Spherical lenses = unnecessary
Been watching the olympic winter games on and off. I've probably seen 1 set of spherical lenses for every 10 cylindrical.
IMO, further evidence that spherical lenses don't offer any appreciable increase in optical clarity. Personal preference is one thing, but if the best riders and skiers in the world don't need spherical lenses to do their thing, then I am guessing that us mere mortals don't really need them either.
Given the thinness and (relatively) low refractive index of plastic lenses in ski goggles.... those of you who claim superior optical quality on spherical lenses are fooling yourselves.
My reccomendation: buy goggles for the fit, non-fogging performance, or aesthetic.
