Perfect Fit for 42-Inch Widescreens

This anti-blue-light filter is cut for 42-inch displays with a 16:9 aspect ratio. It targets home users, office workers and families who want to reduce eye strain during long screen sessions. The transparent film also acts as a scratch shield against children and pets. Installation uses pre-applied double-sided tape on all four edges.

Blocks 400–500 nm Blue Light

The filter uses a seven-layer design to block wavelengths between 400 nm and 500 nm, the range most associated with eye fatigue and sleep disruption. The film measures 36.61 inches wide by 20.47 inches high (930 mm × 520 mm). Buyers must verify these exact dimensions against the viewable area of their screen before ordering.

Suits Flat or Raised Bezel 16:9 Panels

This protector fits both flat-bezel and raised-bezel monitors or TVs that match the stated height and width. It is not for screens with different aspect ratios, smaller or larger viewable areas, or curved panels that prevent full adhesion. Anyone unsure of their exact viewable dimensions should measure carefully before purchase.

Questions about this item

How much blue light does the 400nm-500nm filter actually block when the panel is on?

The filter targets the 400nm-500nm wavelength range to reduce blue-light exposure, helping to lessen eye strain and support better sleep while the display is in use.

What mounting method does the 16:9 filter use to stay on a flat or raised bezel?

Double-sided tape runs along all four edges; you peel the top strip first, align the filter to the viewing area, then secure the remaining three sides once alignment is confirmed.

Will the 930 mm by 520 mm sheet cover my 42-inch 16:9 screen without gaps?

The filter measures 36.61 inches wide by 20.47 inches high (930 mm × 520 mm); measure your viewable area — excluding any bezel — and match those dimensions before ordering.
