21-22 Inch Blue Light Filter Panel

This panel filters blue light from 21 to 22 inch monitors. It mounts by hanging over the top edge and includes Velcro strips for extra security. The filter blocks 60% of blue light in the 380 to 480 nm range and 100% of UV light. It measures 19.7 by 12.2 inches and maintains full colour fidelity.

Suits desk workers seeking eye comfort

Office users who spend long hours at a 21 or 22 inch screen benefit from reduced eye strain and improved sleep patterns. The filter also protects the display from scratches and fingerprints. Buyers with monitors outside the 21 to 22 inch diagonal should look elsewhere, as the panel will not fit correctly.

Covers 21 to 22 inch diagonals

The panel handles standard 21 and 22 inch LCD, LED, TV, PC and Mac displays with a 19.7 by 12.2 inch visible area. It runs out for ultrawide, curved or larger screens where the dimensions exceed the filter size. Installation remains simple for compatible models with the hang-and-go design.
