I have been using polarized and photo chromatic lens in my goggles for the last two seasons. Contrast is more related to the tint one uses and different people have different results with different tints regadless of what the label tells you. But I have better than 20/20 vision so I am lucky.
I have also found that whilst one can get away with a lighter lens if it has a mirror in bright light - the non mirrored lens tends to have better low to flat light contrast. mirrored lens also tend to show scratches more ie the scratch refracts light so it is distracting to wear.
If I cannot decide in the car park I just take two pairs of goggles so I do not have to pfaff with lens changes.
This is how the various lenses work with my eyes:
Smith Phenom/ turbo:
Sensor Mirror - pretty good in all conditions except really flat light.
Polarised Rose Copper - awesome in bright to mid low light - actually has better contrast in flat (ie white out) light for me than the Sensor.
RC36 - really good all round lens but not used since getting PRC (above) - now a non mirror spare.
Ignitor Mirror - good in bright to mid light but not as good as PRC - now a spare.
Yellow - for really low/ flat light -only ever use these when I know it is going to be socked in or snowing for the whole day.
I have had Spy Goggles with their persimmon lens which are awesome for just about all conditions. Their bronze/ silver mirror lens is great for bright to mid level light. Their lenses are hardier than Smith lenses. Especially the sensor lenses which seem to have quite fragile coatings (despite never rubbing them when they are damp etc etc).
I have had Smith and Spy Polarcromatic sunglasses for about 12-18 months now and they are both pretty good.
Smith Vector - Polarchromatic Copper Mirror - these are awesome for skiing in all lights except flat light. No big problem because most flat lightsituations for me equate to rubbish weather so I have goggles on my then. I would recommend these highly. They are glass lenses too so they are a bit hardier. Good for fishing in bright light too.
Spy Diablo with Grey Photochromatic lenses - these are my everyday glasses as they really clear things up in low light and stop glare through to medium bright situations. When it is really bright I switch to the Smiths. They are light on the face but the scoop lets too much air in for me when skiing so I do not wear then skiing as I cannot see for the tears. Even though these are not rated as polarized I can see fish in the water with them on and can't with them off so figure that one out.
They both adjust really quickly to light changes even road tunnels are no big problem.
I guess I have a glasses/ goggles addiction too; two pairs of Smith Phenoms Turbos, two pairs of Phenoms, two pairs of Spy Orbits, Smith Vectors, Spy Diablos, Revos (best allround sunglasses ever with a proper glass lens), assorted Dragon Rake (best sports glasses ever)/ Killer Loop and Oakley M frame glasses (and about 25 spare Oakley lenses - used to be sponsored).
I really need to get a grip or have a garage sale.
Anyway hope all that bumpf helps you decide on a brand/ style/ type for your new eyesight.
