InvisiAid Clear Merritt Blue Light Glasses – Black
Part of the InvisiAid Clear lens collection
The Merritt square frame in black with our clear lens — screen-time filtering with nothing visible on your face.
Independently lab-tested by Micro-Light Optics, the InvisiAid clear lens filters 35% of blue light across 400–500nm, with 86% visible light transmission — Category 0 under ISO 12312-1. In practice: it takes the edge off screen light without noticeably changing how colors look, so it's wearable through a full working day, on video calls, and for color-critical work where a tint isn't an option.
A light filter rather than a treatment for anything — the research on blue-light filtering and eye strain is mixed at best, and we set out what it shows on our science page. If your goal is evening wind-down before sleep, the tinted 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.
