ScreenAid Yellow Merritt Blue Light Glasses – Black
Part of the ScreenAid Yellow lens collection
The Merritt in black with our light yellow screen lens — the step up from clear when a bright display still feels like hard work.
Independently lab-tested, the ScreenAid lens filters 60% across 400–500nm at 79% visible light transmission — a Category 1 filter under ISO 12312-1. That's substantially more filtering than a clear lens, with only a slight warm shift, so colors stay usable for everyday work, gaming and browsing.
Lightweight TR90 frame, comfortable for a full day. For color-critical work the clear InvisiAid is the better choice; for the hours before bed, the SleepAid range filters far more.
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.
