I used to wear Fotonyk but they didn’t cover a full range of vision up and down. When I looked at my computer, there was no coverage. These have a larger range of coverage, have a big glasses look and are light/fit well. Changes lenses isn’t overly simple in comparison. But still works fine. I put my own RX lenses in these from a 3rd party.
Awesome, the defender model are simply the best photocromatic sunglasses I have used. The Sintryx looks awesome and the technology of the lenses are the best.
Awesome fit and feel! Had been wanting these for quite some time and finally jumped on them.
