[pct-l] Eyeglass wearers

[Tortoise]

Yes,  these photochromic lenses are available in the US. have been for 
years.

I wear glasses from when I get up to when I go to bed. It seems to me, 
although I may be wrong or just that my information is outdated, that 
the lenses are somewhat slow to change such as when going indoors from 
bright outdoors, or when driving in the daytime and then going into a 
tunnel. Also I'm not sure the lenses become completely clear even in low 
light.  Maybe the technology has improved.

Are there some out there with current experience with these? And how 
well do they combat glare compared to polarized lenses?
