ReadAid Clear Merritt Reader Blue Light Glasses – Black 3.0x
Part of the ReadAid lens collection
Our black Merritt Reader with 3.0x magnification — our strongest, for fine print, labels and close detail work.
The clear InvisiAid lens is independently lab-tested to filter 35% across 400–500nm, with 86% visible light transmission — a Category 0 filter under ISO 12312-1. No tint and no color shift, so it works for books and screens alike.
The same frame also comes in 1.0x, 1.5x, 2.0x and 2.5x. Full measured data for all fourteen of our lenses is on our science page.
