## Summary description

QOLTEC 51073 is a 21.5-inch matte screen protector with anti-glare surface and blue light filter. Designed to reduce reflections and limit harmful blue light from displays, it helps decrease eye strain during prolonged use. Suitable for monitors or all compatible 21.5" screens, it provides a practical protective layer against smudges and minor scratches.

## Long description

QOLTEC 51073 is a 21.5-inch matte screen protector that combines an anti-glare surface with a blue light filtering layer. It is designed for compatibility with 21.5-inch displays and provides a protective overlay that reduces reflections, limits transmission of short-wavelength blue light, and helps prevent minor scratches and smudges on screen surfaces. The matte finish also helps reduce visible fingerprints and diffuse ambient light, improving visual comfort during extended viewing sessions.
Advantages
The matte anti-glare treatment reduces mirror-like reflections and improves on-screen contrast under ambient lighting. The integrated blue light filter lowers the proportion of high-energy visible blue light reaching the eyes, which can help reduce visual fatigue during prolonged use. The protector acts as a physical barrier to everyday wear such as fingerprints, dust and light scratches, preserving the original display surface. Installation is straightforward and the slim, low-profile construction maintains touch sensitivity and image clarity while minimizing added bulk.
Suitable for
 21.5-inch computer monitors with flat screens
 Home or office desktop displays
 Workstations used for prolonged computer tasks such as coding, writing or data entry
 Environments with bright ambient light or window reflections
Key specifications
 Screen size compatibility: 21.5 inches (diagonal)
 Surface finish: matte anti-glare
 Optical feature: blue light filtering layer
 Protection: reduces fingerprints, smudges and minor scratches
 Thickness: low-profile film designed to preserve touch responsiveness and clarity

How to use
Before application, clean the display thoroughly with a lint-free cloth and a mild screen cleaner to remove dust, oils and debris. Align the protector with the display edges and gradually apply it from one side to the other to minimize trapped air; use a soft squeegee or the edge of a credit card wrapped in cloth to smooth out bubbles. If the protector has a removable backing layer, peel it away step by step while pressing the protector onto the screen. For best results, perform installation in a dust-free environment at room temperature.
Usage recommendations
To maintain the protector and the underlying screen, clean periodically with a soft microfiber cloth and avoid abrasive cleaners or solvents. If the protector becomes heavily scratched or delaminated, replace it to preserve optical performance and protection. Keep the product away from sharp objects during handling to prevent damage before installation.
