Photochromic' s for Biking
I have been using these glasses for bike riding for about 3 weeks now.
I ride in different light conditions sunny, cloudy, under elevated highway (Nimitz)
Pros: Good Construction.
No obstructions to periferal view. A plus for street commuters.
Removable sweat pad on brow.
Comfortable does not fall off your face.
Price for what you get.
Cons: The glasses are not dark enough for ridding into the sun.
They take awhile to darken and will not darken if shaded.
I don't know how scratch resistant the lenses are, hopefully I don't find out too soon.
Thanks,
