There are a variety of glasses on the market these days, so you may be wondering, "Do I really need these photochromic glasses to effectively protect my eyes?" The answer to that is: yes! Because while most other glasses only reflect or darken to protect the eyes, this product goes one step further with its intelligent color change .
If you use these glasses in daylight, i.e. in the sun, the lens becomes darker as it effectively filters intense light and thus improves visual acuity. At night or indoors, the lens on these glasses brightens to improve vision and reduce glare. The best part is that this all happens automatically!
