The Mercer System

A lens for every hour you're on a screen.

Different light needs different protection. Lighter tints keep colors true for daytime work. Deeper tints shut blue light down when you're winding toward sleep.

Others vs VELVO

They claim. We publish the data.

Every blue light brand says the same three things. Almost none of them show you a single measurement. Here's the difference.

What others say

✕“Blocks blue light” — no percentage, no wavelength, no proof

✕“Doctor recommended” — which doctor? no name, no source

✕“Premium lens technology” — $150–$270 for the same resin lenses

✕Trust badges that link to absolutely nothing
