23-24 inch Anti-Blue Light Filter Panel

The BFKK panel is a physical screen filter designed for monitors with a diagonal measurement between 23 and 24 inches. It hangs over the top of the display to reduce exposure to high-energy visible blue light and ultraviolet radiation during extended computer use. The product dimensions are 21.5 inches wide by 13 inches high, intended to cover the active viewing area of compatible screens.

Upgrades from basic software filters

Unlike software-based night modes that shift colour temperature, this hardware panel blocks 60% of harmful blue light wavelengths between 380 and 480 nanometres and 100% of UV light. The jump is worth it for users who require accurate colour representation while still reducing eye strain, computer vision syndrome symptoms and potential long-term eye health risks. Installation is immediate with no calibration required.

Suits office workers and home users

The filter maintains full visible colour transmittance for general productivity, browsing and media consumption. It also adds a layer of scratch and fingerprint protection to the screen surface. Buyers needing coverage for smaller, larger or ultrawide displays should look at a different size. Users who prefer a permanent adhesive application or a frameless edge-to-edge fit will not find those features here.

Questions about this item

What are the exact panel dimensions I should measure against my 23-24 inch monitor?

The panel measures 21.5 inches wide by 13 inches high; measure only the visible screen diagonal without the plastic frame to confirm fit.

How do I install the filter and what common step should I avoid skipping?

Hang the panel over the top of the monitor; if the monitor has a curved or thin bezel, apply the supplied Velcro strips to prevent the filter from sliding forward.

Will the blue-light coating degrade and need replacement over time?

The filter blocks 60% of blue light between 380 and 480 nm and 100% of UV light permanently; no coating wears off, so no scheduled replacement is required.
