There is a good reason why amber is a good color. Your eyes are maximally sensitive to light of that wavelength. Limiting your vision to monochromatic light makes it easier for your eyes to focus sharply. This is because light refracts through a greater angle the shorter the wavelength.

 

Regardless of the explanation, it's well known that yellow lenses make it easier to discern contrast in flat light conditions.

A darkish amber is good for all round. Rose is good if the light is alternating between light and dark (skiing through trees with open patches). Yellow and light amber is good for low light.

 

I believe the explanation for blue blocking is that the eye lens is optimized for focusing green light and has a hard time focusing bright blues to UV and to a lesser degree reds to IR. I think snow is very reflective in the blue to UV which reduces shadowing and definition in flat light conditions. That is mostly pseudo-scientific speculation though.

 

Can't go wrong with Smith goggles
