An Anti-Glare Filter is a protective layer applied to screens, such as those on computers, tablets, and smartphones. Its primary function is to reduce reflections and glare from ambient light, making it easier to see the display in bright environments. This is particularly useful for people who work outdoors or in well-lit offices. These filters can be made from various materials, including plastic or glass, and are often designed to be easily attached or removed. By minimizing glare, an anti-glare filter can help reduce eye strain and improve overall viewing comfort, enhancing the user experience with digital devices.
