I'm seeing more and more World Cup racers wearing blue goggle lenses in flat light condition rather than the more usual orange lenses. Anybody tried them?

krekeg, if they're like Oakley's superb Hi Yellow lens they look blue from the outside but they're actually yellow when you look through them & give a lot more light transmission than persimmon/orange.

No these are actual blue lenses. Didier Cuche and Julia Mancuso seem to use them a lot.

It's not something you really notice but as soon as you start looking out for them you see them everywhere - well at least at the World cup races on TV.

seems a bit of a contradiction if you think about, the main reason for wearing goggles with yellow lenses is to block out the blue end of the colour spectrum which is usually the hazy end.

Counterintuitive if one conflates the ability to focus in bright light with eye chemical response in dim light.
Those are the POC Iris Comp. Blue transmissive lenses for low light have been around for almost a decade now, as seen on the Scott Light Amplifier and Night Amplifier lenses.

The responses of rods and cones both contribute to vision at
intermediate and other low-level intensities of illumination. Furthermore, the
human eye response is notdirectly related to the peaks of wavelengths per se,
but rather to an integration of the spectral curve and relative ratios of intensities
of the pigments of the cones and rods. At times only two cones are essentially
effective. As light intensity falls, the human eye becomes increasingly sensitive
to light of shorter wavelengths. At low light conditions such as twilight the eye
is most sensitive to a bue-green light such as 510 nm. The HC tint for the lens
24 desirably approximates the response curves for cone photoreceptors in the
retina, but with certain modifications to enhance the use of the goggle for
certain conditions. Desirably, the goggle lens takes advantage of the shift to
shorter wavelengths in low light conditions by modifying the transmission curve of the lens so as to be more efficient in low light conditions such as by enhancing the response to blue light. |

It does seem odd what with blue being the opposite of orange but used for the same conditions.

Check your assumptions: Low light (overcast, sunset) is not the same condition as brightly illuminated diffuse sky light (fog)

Oh I see, so;
Gray days and late afternoons = blue
Fog and snowing = Orange
Would that be right?

Or yellow.
To reject the color coming from the most diffuse source (blue sky) and therefore most likely to be directly reflected into the eye at random angles by suspended droplets without striking the object of interest first.

Thanks comprex, I'll go with that. Now which colour best suits the rest of the outfit

Or a grey..........?
I must admit I picked out my lens colour as the colour least likely to give an overall colour tint to what I was looking at - I wanted red to look red and green to still look green. Grey seemed to fit this.

krekeg, am i being a cynic for suggesting that the skiers sponsor may dress them out in a never ending succession of different colours/styles of kit in an attempt to shift more product? I am? oh....
Ideally (for Oakley) we'd all have 7 different pairs of goggles - one for each ...er... type of light

red 27, heh, I wish.
My crack wasn't entirely a jest, assuming a constantly improving skier.
Have you noticed yet that all of the response descriptions above assume a stationary observing platform, and that there might be a relationship between lens colour selected and the speed of the skier?
The speed would affect the position of the gaze spot, the depth of focus expected, and the amount of reliance on peripheral vision input vs. well-focused ie. stared-at input (that a truly fast skier wouldn't have time for)?

Also how about the fact that light conditions can vary from minute to minute as the sun moves, as clouds go across the ski, as you ski through patches of light and shade. Until you can get magic second to second reactalite lenses in goggles to cope with each light condition as you encounter it then does it really matter what colour you ski in? I suspect that at some point in any ski run it will be the right colour!!

I don't know why they do so many lenses lol. And i didn't know Ted Ligety had his own Brand! I just bought my goggles (Oakley Crowbar with the pionk shiny lense) Just cause i liked them!

Do I take it that to deal with flat (but not particulalrly poor) light, blue lenses are best? I dislike flat light intensely and usually wear my orangey goggs when it turns up. They improve matters, but not by as much as I'd like. Should I try blue?

Used blue last season and found them very effective on snowy days at picking out detail.
For choice I use my old motocross goggles with hologram skulls because it scares children. Can't see a thing, mind. Come to think of it, that's probably what's scaring the children.

richmond, probably not. Think of blue lenses as for days or nights when a) there is no blue sky and b) there is no water in droplet or crystal form floating in the air in front of your eyes. Both conditions need to be met.

richmond, please step into my online goggle-shop where I will be able to provide you with lenses for every eventuality. It's also a little known fact that the width of the elastic strap that fixes the ocular items to ones cranium also plays an integral part in improving visibilty in otherwise 'flat' light - again, come in-store and I'll be able to kit you out with ...er... 7 different 'bandwidths' to cover every degree of refraction, and at a very modest €49.99 each

red 27, so for only €349.93 I can have a pair of goggs for every occasion, 3 on each arm and one on my face. Bargain! Where do I go?
