This filter reduces eye strain by cutting blue light. 【Screen Protection】The 3H hardness protective film firmly protects your computer's LCD display. 【Double-Sided Use】 Glossy/Non-Glossy - The surface has an anti-reflective (anti-glare) coating to reduce reflections and glare. The other side has a clear, glossy coating for clear visibility, allowing you to choose your preferred side. 【Magnetic Type】 Easy to attach and detach with one action, so you can use it only when needed. You can remove the filter at home and attach it when you're out, allowing you to use it safely and securely according to your lifestyle. 【Safe Operation】 A privacy filter that prevents prying eyes from those around you during travel on the Shinkansen, in cafes, or in the office, allowing you to operate your computer with peace of mind. *Incompatible models: Some Lenovo ThinkPad series models (ThinkPad X390, Yoga, X1 Carbon, etc.) may experience screen blanking due to malfunction of the sleep sensor when the filter is attached. In this case, it may be improved by adjusting the position of the magnet away from the sensor.
