ReadAid Clear Merritt Reader Blue Light Glasses – Black 2.5x
Part of the ReadAid lens collection
The Merritt Reader in black, with 2.5x magnification and our clear InvisiAid lens — reading glasses that also filter screen light.
The lens is independently lab-tested to filter 35% across 400–500nm at 86% visible light transmission — Category 0 under ISO 12312-1, so there's no tint and no color shift. 2.5x is one of our stronger magnifications: best for small print, labels, and close detail work rather than general screen use.
A light filter for comfort rather than a treatment for anything — what the research does and doesn't support is set out on our science page.
A fraction of the price.
Light sensitivity buyers shopping the premium brands rarely realize there's an affordable, lab-certified alternative. Here's the math.
