ROCKBROS Photochromic Cycling Glasses for Men Cycling Glasses Clear Safety Glasses Road Mountain Bike Bicycle Glasses

Not photochromic AT ALL!!Add a few more hard earned money and get a decent one.

These provide excellent eye protection, are comfortable, and darken in bright sunlight. They come with a hardshell carrying case and cleaning cloth. This is my second pair and they've stood up well to the abuse of mountain biking wear and tear.

No son pesados y tienen un buen tamaño para una persona promedio entre 1.70 y 1.80

It doesn't get dark in the sunlight as stated and the quality is not very good, average. The case it came in is very good, better than the quality of the glasses :D

Have used these on and off for a few months as cycling glasses. They are ok on an overcast day whilst road biking letting enough light in. When the sun comes out they eventually darken a little but not quite enough for really bright sunshine. The transition is not fast though as I found out mountain biking through trees - they take a while to lighten up which can be a problem if you’ve just ridden under a tree canopy at speed! But for the price they seem a fair deal.

No tolero mucho la luz del sol en los ojos y mi temor era que los lentes al oscurecer no tuvieran ese efecto de polarizado que tienen otros modelos, pero hasta ahora los he sentido bastante cómodos tanto de día como de nocheAjustan bien así que no se van moviendo
