Protetor de ecrã QOLTEC 51075 23,8 polegadas anti luz azul, mate anti brilho

QOLTEC 51075 is a 23.8-inch monitor screen protector with an integrated anti-blue-light filter and a matte anti-glare surface designed to be mounted on 23.8" displays. The protector reduces the amount of short‑wavelength blue light reaching the eyes and minimizes reflections from ambient light sources, maintaining screen legibility while improving viewing comfort during prolonged computer use.

Advantages

The matte anti-glare coating disperses reflected light to reduce mirror-like glare without significantly darkening the display. The anti-blue-light layer attenuates harmful short-wave blue light to help reduce visual fatigue and potential sleep-cycle disruption associated with extended screen exposure. The protector preserves touch sensitivity and image clarity for most office, study and multimedia applications while adding a consistent, uniform surface finish to the monitor.

Suitable for

• Office work with prolonged monitor use
• Home study and remote learning sessions
• General multimedia and video streaming
• Environments with overhead or window reflections

How to use

Clean the monitor screen thoroughly with a lint-free cloth and, if needed, a mild screen cleaner to remove dust and fingerprints. Align the protector with the display edges and apply it starting from one side, smoothing across with a soft card or cloth to remove air bubbles and ensure full contact. Reposition gently if necessary before full adhesion. Follow any included manufacturer instructions for attachment and removal to prevent damage to the display surface.

Recommendations

For optimal comfort, use the protector in combination with regular breaks from screen work and correct monitor positioning. Avoid abrasive cleaners and sharp tools when installing or cleaning the protector. If color-critical work is required, verify color rendering with and without the protector to ensure it meets specific visual requirements.
