I wrote the original review, and I'm still in love
Someone said that photochromic lenses are good for cycling. I couldn't disagree more, they are overtly dangerous, at least on the backroads in the Catskills where I ride. I don't know about you, but when I'm descending from a sunny hillside into a heavily shaded area, I don't want to wait 15 seconds for my lenses to adjust. This isn't something that happens occasionally, or even once per ride, more like dozens of times on every ride.
Assos got it really right with the abrupt transition between tint and clear, and I wouldn't be surprised if everyone starts following their lead.
I know they look odd but they are so much better than other sunglasses I've had that I don't really care. As I said in my review, it isn't often that a product comes along that so clearly improves the riding experience.
I guess the value of photochromics is relative to your own personal use and local conditions. I for one find them really useful, particularly starting in the dark and then finishing on a bright sunny day. Even for fast changing conditions, I can't see how they're any more dangerous than fixed darker shade sun glasses...
Sure the Assos glasses no doubt deal with abrupt changes better than glasses with a fixed dark shade, but do they deal with bright sunlight as well as a fixed dark shade glass does? Or, putting it another way, do the Assos glasses work any better in variable conditions than any other fixed clear or near to clear (eg: yellow) glass?
So it comes down to personal preference. Buy what you like and what works for you, not what someone else finds works in a different part of the world.
