Anti-glare filters are protective screens designed to reduce reflections and glare from surfaces like computer monitors and smartphones. They work by diffusing light, making it easier to see the display in bright environments. This can help reduce eye strain and improve visibility, especially for people who spend long hours in front of screens. These filters come in various forms, including adhesive films and clip-on attachments. They are commonly used in offices, schools, and homes to enhance comfort while using digital devices. Many users find that anti-glare filters improve their overall viewing experience, particularly in sunny or well-lit areas.
