9 Things to Know About our Spectron Polycarbonate Lenses

 

1 - All of our Spectron Polycarbonate lenses are completely shatterproof and made with ballistic material used for helicopter windshields. You can run it over, smash it with a hammer, drop them from a 50 story building, they won’t break.

2- The Spectron 4 (VLT 5%) is similar to the Spectron 3+, but provides maximum protection against dazzling sun in conditions of strong reverberation with the use of an anti-reflective coating.  This anti-reflective coating reduces eyestrain and eliminates interference glare. Spectron 4 lenses are perfects for mountain activities.

 

3 - The polarizing filter of the Polarized 3 (VLT 12%) and Polarized 3+ (VLT 11%) eliminate the glare from water surface snow or windshield for a better and clear vision. The Polarized filter 3+ produces the same mirror effect as the Spectron 3+ to improve the filtration of visible light.

 

4 - Spectron 3 and Polarized lenses are appropriate for driving but Spectron 4 is not recommended for driving because the lens is extremely dark.

 

5- Every Polycarbonate lenses can be use for mountains, performance or water sports. You will choose your lens depending of your light sensibility.

 

6 - If you wonder why you don't have a clear vision when getting into the woods or when the weather is cloudy, it is because Spectron Polycarbonate lenses are not photochromic and will not transition for you from light to dark or from dark to light.

 

7 - Our lenses and frames come with our lifetime warranty so rest assured that if anything goes wrong with Julbo’s eyewear, we’ll take care of and defect. Unfortunately we don’t cover scratched lenses from overuse or misuse.

 

8 - A special baby lens is available at Julbo. The Spectron 4 baby provides a maximum protection against Sun's UV rays.

 

9 - All of our Spectron Polycarbonate lenses offer an extreme suns UV ray's protection (VLT from 13% to 5% depending on the lenses).

 

 

 

9 Things to Know About Our Cameleon Lens

If you’re looking for a photochromic performance lens that’s going to give you some serious protection in the mountains, our Cameleon lens is the one for you.

Our Cameleon lens is the ultimate mountaineering, alpine climbing lens that blocks the sun’s harmful rays, cuts snow glair and keeps your eyes from burning in extreme environments. Our Cameleon lens has been used to conquer peaks from Everest to Rainer. Here are a few features and tech specs about the Cameleon lens you might not have known about.

1. Most of photochromic lenses are affected by extreme temperature. The Cameleon lens is non-temperature sensitive. It will transition ( 5-20% visible light transition / Category 2 to 4) from light to dark and dark to light in about 25 seconds regardless of how cold or hot it is.

2. In the mountains, especially on snow and glaciers, the sun can cast intense glares so we’ve fully polarized the Cameleon lens.

3. We’ve added an oil-repellent layer so it will shed rain or any moisture you may encounter in the alpine zone.

4. Our Cameleon lens comes with an exceptional anti-fog coating that fights moisture and condensation on the lens. Pro tip: If you sweat or have oil buildup on your lenses, be sure to wash it with a little dish soap and warm water, it’ll wash away any buildup from sweat.

5. All of our photochromic lenses are completely shatterproof and made with ballistic material used for helicopter windshields. You can run it over, smash it with a hammer, drop them from a 50 story building, they won’t break.

6. Our lenses and frames come with our lifetime warranty so rest assured that if anything goes wrong with Julbo’s eyewear, we’ll take care of and defect. Unfortunately we don’t cover scratched lenses from overuse or misuse.

7. If you’re driving with them on and wondering why you’re still squinting, it’s because our Cameleon lens is UV activated and your vehicle windshield has a protective UV layer, preventing the Cameleon lens from transitioning. 

8. The Cameleon lens is the darkest photochromic lens Julbo makes.

9. We also offer several ski goggles available with our Cameleon lens.

lunette de course à pied

Le rendez-vous annuel des adeptes du 21k, qui se tiendra à Mont-Tremblant le 14 août 2016, approche à grand pas. Que ce soit l'objectif de votre saison ou d’une vie, la course à pied est une discipline exigeante, endurante et technique pour tout le monde. Ayez les mêmes attentes pour l'ensemble de votre équipement!

Considérée souvent à tort comme un simple accessoire de mode, la lunette de soleil, au-delà du style, peut être un réel outil d'aide à la performance.

L'un des principaux critères dans le choix de votre paire pour vos sorties doit être la légèreté. Plus une monture est légère, plus vous l'oublierez vite et pourrez la porter du début jusqu'à la fin.

Mais pour la garder sur le nez durant toute la course, il faut également que les verres s'adaptent à la luminosité ambiante tout en protégeant vos yeux des UV. Verre photochromique, évolutif, adaptatif, variable, changeant… quelque que soit le terme utilisé, l'intérêt pour vous reste le même : emmener une seule paire de lunettes de soleil pour faire face à toutes les situations d'ensoleillement et ce quel que soit le temps !

En plus de bénéficier d'une protection solaire optimale, il est également important d'éviter l'apparition de toute gêne visuelle dû notamment à la transpiration. Nos verres photochromiques Zebra (cat. 2 à 4) et Zebra Light (cat. 1 à 3) possèdent un traitement antibuée en face interne.

Et si en plus vous les combinez avec des verres suspendus, vous êtes sûr de ne jamais rencontrer ce problème !

Julbo Goggle Review: How to choose the right lens?

Philippe Gautier’s Review of Julbo’s Goggle lenses
Association of Canadian Mountain Guide Ski Guide
Professional Member of the Canadian Avalanche Association
Owner and operator of Névé Expeditions: www.nevexp.com

Six weeks wearing Julbo lenses - first as a guide at a remote skiing lodge in the Coastal Range Mountains of British Columbia, and then, for more remote lodges, as a guide on various ski mountaineering trips through backcountry all the way from Whistler to Lake Louise.

I’m mainly looking for a go-to ski mountaineering lens, but I also need to know what’s out there for my other sportive pursuits. I figured that the ups and downs I’d encounter in both weather and terrain over the course of six weeks would be the perfect challenge for Julbo’s ambitious claim, ‘’Julbo, you only need one lens.’’ If what Julbo says is true, my actual mission is to figure out which one of their lenses best suits my adventurous needs. Which will it be? The Snow Tiger? The Zebra Light? The Zebra? Or  will it be the Cameleon?  Read on to find out.

Julbo Snow Tiger Lens

Snow Tiger

I used the Snow Tiger lens for the first time on my initial flight at a heli-skiing operation. The mountains and glaciers looked different to me, and it wasn’t only because I was seeing them for the first time – I was seeing them in pink! The Snow Tiger makes some snow textures appear in light tones of sparkling pink – never have I skied with a lens that is so sharp and precise that it reveals snow textures.

It took me a while to get used to seeing the world in pink, but it was worth it. For example, I was in a corn cycle and it was quickly apparent that I needed to ski ‘’The Pink.’’

My best experience using this lens was over a few hours on clear days in areas where I needed uncompromised visual acuity. For prolonged exposure to the sun or in lower-visibility conditions, I preferred the Cameleon or the Zebra light lens.

Julbo Goggle Zebra lens

Zebra

The Zebra is a true in-between lens. It darkens well on clear days and brightens up nicely in lower-visibility conditions. If I had to carry only one lens for all weather conditions, this would be it. It’s great for anyone looking for a general all-weather lens.

Julbo Goggle Cameleon lens

Cameleon

The Cameleon was designed to handle a wide variety of light conditions. It’s a darker lens, and although I would like it to darken a little bit more on sunny days, it quickly adapts when the clouds roll in, and again, when the sun comes back out. Compared to the Snow Tiger, it will better protect my eyes for longer periods on clear days, but without as much contrast and definition, and definitely no pink!

Julbo Goggle Zebra light lens

Zebra Light

When it got nasty (think blowing snow in low-light conditions), the Zebra Light out-performed every other lens. In high overcast conditions, the thin clouds let enough UV through for the lens to react and darken a little more than it needs to, but otherwise, it’s great. My mission was to find a go-to ski-mountaineering lens, and I’ve found it.

Conclusion

In summary, the optimal weather conditions for each lens are as follows:

  • The Snow Tiger: Partly cloudy and, when needed, in clear sky conditions
  • The Zebra: All Weather
  • The Cameleon: Clear Skies
  • The Zebra Light: Blowing snow, cloudy and other snowy conditions

The Zebra Light is now my go-to ski mountaineering lens, and that’s because, generally, one lens is all I really need for ski mountaineering. However, when serving as a guide for any form of mechanized skiing, I’ll need a lot more from my lens, and that’s where the other lenses will come into play.

 

 

Tackle some Dirt!

Alexandre Provost - Adventure Racing

Gravel Grinders are Today’s new and refreshing road biking events. These are rides or races that mostly take place on gravel roads instead of on pavement. Participation is open to everyone, with no sanctioning or license needed.

I first took part in Rasputitsa in 2014 and I’m not sure I’ve ever had more fun on a bike. I only placed 48th, but I’d never been happier. I had a blast! How could I be bored with the massively amazing start, the friendly peeps, the strava segment, the maple syrup shots at the top of Cyberia*, all with the fun of being surrounded by a small group riding and attacking the hills?

*Cyberia: a segment of Rasputitsa where you may… or may not… be able to ride your bike…

Alexandre Provost - Adventure Racing

Rasputitsa attracts a wide variety of participants: roadies, mountain bikers, cyclo-crossers, riders on borrowed bikes and bearded single-speed dudes. Even the odd pro shows up sometimes! It makes out for a thrilling ride for everyone; you can to hang on to a group that matches your skill set, and hope for the best!

You don’t really need a cyclo-cross bike for the event, even though it’s on a gravel road. I’ve been using my road bike with 700x28 tires, and my friend used his regular 700x23 road tires and rode just fine! Some guys even showed up with fat bikes at Rasputitsa, and certainly found themselves riding with a certain edge in Cyberia!

Alexandre Provost - Adventure Racing

Like trail is to running, gravel races are not mainstream and probably won’t be (thank God) but the phenomenon is growing, and you can find more and more of them out there. The Après Vélo party is always certainly the highlight of the day - complete with a BBQ, local beer and your fellow adventurers’ stories of their day.

Dirty 40 and 100 à B7 are two very good organizations that offer fun days rife with challenges that are well worth the post-race endorphins payoff:

Raputitsa in April http://www.dirty40race.com/

Dirty40 on September 5th http://www.dirty40race.com/

Do yourself a favor and tackle some dirt this summer!

Expédition Alaska: la course pour les fous de course d'expédition

À chaque année, mes co-aventuriers et moi nous demandons quelle course-expédition aborder à l’année d’après. Expédition Alaska tombait bien dans nos cordes : navigation, terrain et conditions… tous difficiles. Bref, un regroupement d’éléments jouant en notre faveur! De plus, grâce aux 21 heures de clarté nordique par jour, nous allions en avoir plein la vue.

Quelques embûches plus tard, nous nous sommes finalement retrouvés au point de départ. Notre menu pour la semaine allait comprendre une traverse de glacier, du packraft sur rivières et lacs, une escalade de montagne, du rafting sur rivière glaciale et du vélo de montagne sur une route parsemée de cols et de sentiers. Pour le dessert : kayak de lac et de mer.

Le départ est donné! Nous débutons, sans lâcher les côtes des meneurs, sur le prologue de 20 km à partir de Lake Eklutna, à l’assaut du glacier! À la fin de notre longue journée parsemée de sommets et de crevasses, les troubles respiratoires qu’éprouvait notre co-équipière se sont aggravées. Nous terminons cette première transition en 6e place.

Le lendemain arrivé, notre quatuor devient trio – notre co-équipière ne reprend pas la course, suite à une attaque d’asthme. Les règlements de la course dictent que toute équipe ne terminant pas la course intacte serait placée dans une catégorie inférieure. Extrêmement déçus, nous avons tout de même continué, les 3 gars, le couteau entre les dents, déterminés à montrer que nous faisons partie de l’élite.

Nous nous embarquons dans la section nommée ‘’The Soul Crusher’’ par l’organisation, laquelle nous terminons avec le 2e meilleur temps après 36 heures de trek en montagne et packraft (la 1ère équipe a terminé en 34 heures). Une fois sur la montagne, tout se passait bien, mais la descente en a embêté plus d’un, même que certaines équipes en finirent après près de 3 jours…

Nous entamons les 5 prochains jours en donnant tout ce que nous avons pour parcourir le plus de distance après les gagnants. Avec un ronflant 9h de sommeil, nous rallions l’arrivée à Mile Zero de l’Iditarod Trail, au cœur de Seward.   

Les conditions furent difficiles et nous étions mouillés à 80% du temps, mais nous en revenons avec le sentiment d’avoir fait tout ce dont nous pouvions, en prenant en compte les circonstances.

Nous avons porté nos Julbo Venturi tout le long de l’expédition,  soit sur le glacier, en forêt et dans l’océan! Soumis à de telles conditions, les lentilles Zebra light étaient de mise et ont rempli leur rôle à merveille. Je crois les avoir gardé pendant un cycle complet de 24h sur le bout de mon nez alors que nous pagayions sous la pleine lune sur Lake Kenai!

Malgré qu’Expédition Alaska n’en fût qu’à sa première édition, nous avons eu le droit à une course plus grande que nature, s’étalant sur 6 jours et nuits, à laquelle nous avons rajouté un septième jour pour nous permettre de participer à la course Mount Marathon à Seward, AK.

J’ai parcouru le trajet avec mes partenaires habituels, Jean-Yves et Jonathan Dionne. J’ai une confiance sans bornes envers ces deux frères : nous avons bravé plusieurs tempêtes ensemble et en affronterons maintes autres. Nous nous complétons bien dans nos rôles, un élément important, lors toute course d’aventure, qui devient crucial lorsque la course et d’une telle longue durée.

Pour les intéressés, le lien ci-dessous vous amènera à découvrir la course d’aventure telle que décrit par la Canadian Adventure Racing Association : http://www.canadianadventureracing.com/#!about/cee51

Julbo Ambassador Laurra Perry Wins Finger Lakes 50M

Laura continues her winning streak as she prepares for the infamous Canadian Death Race. She is aiming for a top 3 results. If you want to learn about Laura's race, read her account bellow.

WOW, where to start?!?! I'm still in complete shock over how this race unfolded and how the day ended up! :)  What an amazing race! Finger Lakes is so well organized from start to finish, with amazing volunteers, aid stations, participants and a fabulous Race Director!


So let me take you back to why I signed up for this race... I wanted a race that was tough, muddy and would prepare me mentally for some of my upcoming races.  I had heard about Finger Lakes 50s a while back, and heard how the course was often "a complete mud-fest"... SOUNDED GOOD TO ME!

Well, in the days leading up to the race IT RAINED! and the forecast called for MORE RAIN... I enjoy mud to a point, but ONLY to a point.  I knew that this was going to be a tough one!  The worst part was that they were calling for thunderstorms, which made me nervous.  There are a lot of open cow pastures that we had to run across and I was scared to death about lightening! Oh well, not much I could do about it.

We arrived at our hotel only to learn that there was no kitchenette AND NO TOASTER!! (Anyone that knows me, knows that I actually have a "race toaster" that I bring to races that I know there won't be one in the room).  I am a creature of habit, so what did I do? I went and bought a 2nd "race toaster", my mind was at ease, I could have my bagel! DISASTER AVERTED!

We woke up at 4:00am to the lovely soothing sound of... you guessed it... RAIN! OH YAY! UGH!!



Before the race I started to think about all the great women I have been inspired by lately, my coach Ann Trason, Sally McRae, Kaci Lickteig, just to name a few.... I was ready to rock!

The hard part about this race is that the 50k and 50M all start together, and there's no way to know who's doing which race.  The gun (or actually the horn) went off, and people FLEW down the first section.  I tucked myself in just behind the lead pack of men and started running a very comfortable pace.  Soon I was running with another great female runner Nora McIver-Sheridan, she was awesome! She was doing her 1st 50k race, and was a blast to run with (she was speedy... and ended up winning the 50k, yaaaay Nora!!)

So what was the condition of the course you ask??? Well, there was MUD, some more MUD and MUD on top of MUD! 
This was actually an "ok" part of the course
 


There were many sections of the course where the mud and water was knee-deep, a true shoe-sucking course.  Bloody awful!! (and i loved it!)

The course isn't super hilly, but it is technical and has non-stop rollers.  The first loop flew by so fast, it was incredible! My legs felt fabulous, and I was in such a good place mentally.  I remember coming through the first 26k split and saying to the RD Steve Shaum "Oh, I'm definitely doing the 50M, this is awesome!"



As the day progress the course just kept getting worse! The mud sections became deeper and longer and the water-logged sections got WAAAAY worse.  But it really didn't bother me, I knew I was running strong.  At one point I passed 2 guys that were running together, and they said "you're running strong, are you in the 50k?"  I replied "Nope, 50 mile"... in my head I thought "yup, you just got chicked!"

On the 3rd loop Corey jumped in with me to pace me (he needed to get a run in anyway, so it worked out perfectly).  Corey kept me moving (often faster than I would've liked) and he encouraged me to "keep moving" when the mud started to REALLY PISS ME OFF! He would say to me "you're tougher than the pain".  I don't remember how many men I passed on my last loop, but it was a lot!!

Now, don't get me wrong, the race wasn't all sunshine and rainbows! I had some really low points where my hips were screaming at me, and my legs were slipping and sliding through the mud. I took one really nasty fall and ended up banging up my knee pretty badly.  BUT I didn't let it get me down, I just kept pushing forward.  I kept saying to myself  "channel your inner-Ann", and it worked! Man-oh-man does she inspire me!!! 


I crossed the finish line 1st place female, 7th overall and 1hour and 32 minutes ahead of the 2nd place female!  I got the most amazing trophy (a GIANT cow), a growler of local Pale Ale, a pint glass, and a fleece jacket!  


Awesome Cow Trophy! (we ran through cow pastures!!)
I met some truly amazing people during this race includingKevin Hartstein and Nancy Kleinrock!  I also learned a lot about how much suffering I can endure with a positive attitude.  I also learned that Corey truly believes in me, and only pushes me because he knows I can take it (thanks babe).

 NO BLISTERS!!


 A HUGE thank you to my parents and Corey for crewing for me during the day and making sure that my nutrition was on-point!




I want to thank my amazing coach Ann Trason for making sure I was 100% prepared for this race.  Ann is caring, passionate and so motivating!!  We went into this race with the plan to run it as a training run for my upcoming races, and I did just that! I felt strong all day, and really learned what i need to do for the rest of the season.  Without Ann's guidance I don't know if this would've been possible!

Thanks to my amazing sponsors for their support!!

Can Clouds Protect your Eyes Against the Dangers of the Sun?

It is important to remember that, even in cloudy conditions, the sun is still dangerous in the mountains.

You should not count on overcast skies to protect you as cloud cover provides only limited filtration. While UV light can be stopped by some clouds (alto-cumulus), cirrus clouds have no filtration effect at all.

50% of the sun's radiation passes through fog. It is therefore necessary to protect yourself in the mountains, even when conditions are cloudy.

At high altitudes in overcast conditions, you may frequently find yourself in the upper layer of the clouds. The radiation here is intense due to the effects of light diffraction. The risks are therefore even higher than in fine weather.

Julbo has developed a range of products specially adapted to these extreme conditions that combine Category 4 lenses, wraparound frames and protective side shields. Check out our mountain collection 

Julbo Explorer

The Most Common Eye Disorders Found in Climbers
 

****DISCLAIMER:  For informational purposes only. Readers should report any discomfort or pain to their eyes to their doctor.

 

Summary
Solar radiation is estimated to increase in intensity by 10% at every 1,000 m altitude threshold. Exposing oneself (and one's eyes) to UVB rays at these heights is particularly dangerous. It can never be said enough: neglecting to wear sunglasses in high-altitude light environments can lead to permanent eye damage. 
The 4 most common eye disorders among climbers are: photokeratitis or snow blindness, erythropsia, white-out syndrome, and corneal frostbiteAll of these disorders can be prevented by making sure proper eyewear is part of your equipment when setting out into high-altitude light environments.

 

THE MOST COMMON DISORDERS

1- Photokeratitis or Snow Blindness

Condition & Cause: Erosion of the epithelium (the layer of surface cells covering the cornea), caused by extended exposure to intense light (high UVB radiation).

Symptoms: 4 to 6 hrs after exposure, you will feel pain and a granular sensation under the eyelids. You will also experience photophobia (pain increased when in the presence of light). Conjunctival redness, excessive tear secretion, swelling of the eyelids and difficulty opening the eyes, as well as intense blepharospasm (involuntary blinking of the eye), are also symptoms.

Treatment: Rest in a dark room / eye patch(es) / application of an antiseptic eye wash and ophthalmic ointment. During recovery, avoid eye washes containing an anaesthetic. Contact lenses must not be worn for 4 to 5 days.

2- Erythropsia

Condition & Cause: Exhaustion of the retina resulting from prolonged exposure to intense light stimulation. This disorder is rarer than snow blindness.

Symptoms: Objects take on an abnormal reddish hue.

Treatment: Rest in a dark room, application of eye patches and ophthalmic ointment

Snow blindness and erythropsia do not have long-term after-effects if treated in time. However, snow blindness can endanger the lives of mountaineers in high-altitude environments by depriving them of their vision while mountaineering.

3- White-out Syndrome

Condition & Cause: Frostbite of the eye or eyelids as a result of being exposed to extremely cold temperatures.

Symptoms: Initially, you will experience pain, blurred vision, photophobia and excessive tear secretion, or even a total loss of vision. Later, symptoms include a reduced visual acuity that is associated with a loss of depth perception  resulting in disorientation and sensations of vertigo on the field.

Treatment: Protecting the eyes from cold, and warming them up should ensure good recovery.

4- Corneal Frostbite

Condition & Cause: The temperature of the cornea is reduced to a temperature between 29 and 36 °C. Extreme cold and/or snow combined with wind can lead to frostbite of the cornea.

Symptoms: At first you will experience blurred vision, excessive tear secretion, photophobia or even a total loss of vision. Later, symptoms include a reduced visual acuity associated with a loss of perception of depth perception resulting in disorientation and sensations of vertigo on the field.

Treatment: Removal from the cold. Eye patch(es) and gradual passive heating  for 2 to 3 days. Tip while on the field: use a warm teabag to heat up the eye.

Warning: If not treated correctly, corneal frostbite can lead to necrosis and you could even lose your eye.

 

 

Remember that all of these disorders can be prevented by wearing equipment suitable for high-altitude conditions. Julbo has developed a range of products specially adapted to the conditions mountaineers find themselves in. Our protective eyewear is equipped with Category 4 lenses, wraparound frames and protective side shields. Check out our mountain collection

Comment choisir une lunette de soleil pour enfant? Allez-y pour la lentille!

L’ INDICE DE PROTECTION SOLAIRE 

Les filtres solaires doivent répondre à la norme européenne (EN1836). Plus particulièrement, ils doivent :

•bloquer 100% des rayons UV;
•empêcher l’éblouissement;
•avoir une résistance mécanique suffisante (déterminé selon un test d’impact);
•avoir une qualité optique suffisante (catégorie optique ou indice minimum de 1 ou 2; détails dans le tableau ci-dessous):


Tous les modèles Julbo vous sont proposés en indice 3, pour une protection polyvalente, et en indice 4 pour une protection optimum en milieu très exposé; et pour les plus petits.

Tous les modèles de lunettes solaires Julbo sont équipés de nos verres Spectron 3, Spectron 4 ou Spectron 4 Baby. Pour répondre aux normes de sécurité et de confort, ces verres sont fabriqués en polycarbonate (les verres minéraux étant dangereux en cas de bris). 

      

Le Polar Junior est un verre polarisant qui s'adapte bien aux lunettes d’enfants. Plus léger, son filtre polarisant coupe les reflets (ex : à la surface de l’eau) et permet à son porteur de lire le terrain plus finement grâce à l’accentuation des contrastes.

Le verre Zebra est un verre photochromique, proposé sur certains modèles sportifs. Son niveau de protection s'adapte aux conditions lumineuses environnantes.

Son indice de protection varie entre le 2 et le 4, permettant aux enfants de porter leurs lunettes toute la journée, peu importe la météo.

How to Choose a Pair of Mountain Sunglasses?

High-mountain frames must provide the wearer with optimum protection. In addition to a Category 4 lens, they must offer good protection against direct and indirect radiation, as well as from external elements. They must also be adapted for use in extreme sports.

A good frame must therefore provide:

  • Total coverage / protective side shields.
  • A pronounced curve.
  • Excellent grip.
  • A headcord (ideally).

    Comment choisir une lunette de soleil pour enfant? Il faut porter attentention à la monture!

    LES MONTURES POUR ENFANTS

    Les lunettes de soleil ne protègeront vos enfants que s'ils acceptent de les porter! Au-delà de l’évidence des bienfaits de leur port, les besoins et la morphologie des visages de nos enfants doivent être pris en compte. De plus, ils courent partout, alors les montures seront soumises à davantage de mouvements et de chocs s'ils ne tiennent pas en place! 

    La forme du visage enfant se caractérise par des traits spécifiques (ex: nez peu formé chez les très jeunes…) qui évoluent au fur et à mesure qu'ils grandissent. Il faut donc choisir des montures qui leur conviennent selon leur niveau de développement.

    1- La protection des yeux :

    • les montures doivent suffisamment couvrir les yeux afin de bloquer les entrées lumineuses provenant de tout angle;
    • la taille de la monture doit bien convenir au visage.

     

     


    2- La forme des montures doit tenir compte des particularités du visage des enfants :

    • la racine du nez est peu développée
    • le visage est plat

     

     

     

    Tel que décrit plus tôt, les besoins spécifiques en terme de monture, de choix de verres et de couleur évoluent selon l'âge de votre enfant. Julbo vous propose des montures pour chaque étape de leur croissance.  En voici quelques exemples:

    Why Should You Wear Sunglasses in High Altitude?

    Summary:

    Solar radiation is estimated to increase in intensity by 10% at every 1,000 m altitude threshold. Exposing oneself (and one's eyes) to UVB rays at these heights is particularly dangerous.

    Therefore, the intensity of solar radiation is 1.5 times greater at 2,000 m and 2.5 times greater at 4,000 m (over sea level). At this level of exposure, you will require a high quality lens that offers a Category 4 protection such as the Spectron 4, Cameleon, or Zebra lens, in order to preserve eye health.

     

    THE DANGERS OF THE SUN IN HIGH-MOUNTAIN ENVIRONMENTS

    Anyone who practices high-mountain sports must be aware that they are operating in a risky environment.

    While the risks linked to the mountains themselves may be obvious, those caused by exposure to the sun at high altitudes are more difficult to understand. Let me shed some light on the subject.

    Exposure will vary depending on the thickness of the ozone layer in the atmosphere (which acts as a natural filter), the season and the angle of incidence of the sun's rays, which changes throughout the day.

    Solar radiation is estimated to increase in intensity by 10%  (between 4 and 16%) at every 1,000 m altitude threshold. Exposing oneself (and one's eyes) to UVB rays at these heights is particularly dangerous. In addition, the snow often present in the mountains reflects between 80 and 90% of solar radiation, compared with 20% on non-snowy ground.

    Therefore, the intensity of solar radiation is 1.5 times greater at 2,000 m and 2.5 times greater at 4,000 m (over sea level). At this level of exposure, you will require a high quality lens that offers a Category 4 protection such as the Spectron 4, Cameleon, or Zebra lens, in order to preserve eye health.

    Neglecting to use protective eyewear in high-altitude environments can lead to permanent damage to your eyes. The 4 most common eye disorders among climbers are: photokeratitis or snow blindness, erythropsia, white-out syndrome, and corneal frostbite. All of these disorders can be prevented by wearing ocular equipment suitable for the conditions.

    Since 1888, Julbo sunglasses have protected our most daring adventurers on their escapades up into all of our world's greatest mountains. Used on expéditions from the jagged Antarctic landscape, to the Alps, to the 8,000 m Himalayan peaks, Julbo has honed its expertise in high-mountain sun protection and has become a benchmark brand in the field of high-altitude eyewear.

    Les enfants et les bébés ont-ils besoin de lunettes de soleil?

    Les enfants sont souvent dehors pour jouer ou pratiquer des activités sportives. Ils sont donc naturellement exposés aux rayons du soleil. Cependant, le cristallin des enfants est perméable aux UVA, Il ne devient imperméable aux UVA qu'à l'âge adulte.


    VRAI ou FAUX?

    1- En montagne, l’intensité des rayons UV est-elle plus forte ?

    VRAI. En montagne, l’intensité des rayons UV augmente de 10% à tous les 1000 m. Il ne faut donc pas se protéger que de la clarté et de la réverbération liées à la neige.

    2- La visière de la casquette protège bien les yeux des enfants contre le soleil, vrai ou faux?

    FAUX, car une part importante du rayonnement vient de la réverbération :

    -sur la neige : jusqu’à 90% de réverbération
    -sur l’eau : jusqu’à 30 % de réverbération
    -sur le sable : jusqu’à 28 % de réverbération

    3- Qu'on soit à la montagne ou à la mer, lorsque le ciel est couvert, il n’est pas nécessaire de porter des lunettes de soleil. Vrai ou Faux?


    FAUX. Les nuages ne filtrent qu'au maximum 10% des rayons UV. D’ailleurs, les coups de soleil sont fréquents dans ces conditions car il ne fait pas forcément chaud et on ne prend pas la peine de se protéger…Il en va de même pour les yeux.


    Marque pionnière dans la protection solaire pour les yeux des enfants, Julbo s’engage plus que jamais auprès des opticiens, des professionnels de santé et des consommateurs pour les sensibiliser et leur proposer les solutions de protection les plus adaptées aux yeux des enfants.
