[Filter Size] 540*340mm (Compatible with 23-24 inch LCD monitors, TV monitors, and gaming monitors) *Can also be used with 20-22 inch monitors as long as the protruding parts are not a concern. [Privacy Protection] This "anti-spy filter" features a 60-degree viewing angle and polarized properties, making the screen appear clear when viewed from the front but completely black from the person sitting next to you. [Blue Light Filter] It also blocks approximately 50% of the blue light emitted by LED LCD displays. *Blue light is known to reach the retina without being absorbed by the cornea or lens of the eye, and can cause retinal dysfunction. *As it does not prevent reflections, it is not recommended for use in environments with high sunlight. [Easy Installation and Removal] Simply hook the filter onto your monitor for easy installation. This durable acrylic protective panel protects your precious LCD screen from impacts. Even if you replace your monitor, you can continue to use it as long as it is the correct size. Unlike stick-on screen protectors, you can apply them only when necessary. [High Hardness] Worried about children touching, scribbling, or bumping into your monitor, or even your pets scratching it? This 2mm thick screen protector has a 10H surface hardness, providing excellent protection against scratches and impacts. Use it to protect your monitor when you're not using it.
