ECVL Day & Night Lens

Here is the short summary of the ECVL Day and Night Lens:

This is a 2-in-1 lens designed for 24/7 wear, combining two major technologies:

• Anti-Blue (Indoor/Night): The lens remains clear indoors. It blocks harmful blue light from phones and laptops to reduce eye strain and headaches.
• Photochromic (Outdoor/Day): The lens automatically turns dark (like sunglasses) when exposed to sunlight, protecting your eyes from UV rays and glare.

Key Specs:

• Material: 1.56 Index (Thinner and lighter than standard lenses).
• Protection: UV400 (100% UV protection).
• Best For: People who want one single pair of glasses for both computer work and outdoor travel.
