YMYWorld 13.3-inch 16:9 Magnetic Screen Protector, Privacy Filter, 3mm Wide, Removable, Blue Light Blocking, for Laptops and PCs

Compatible Models: 13.3-inch 16:9 Screens. Dimensions: Filter only: 294mm x 168mm (Vertical/Horizontal variations: +/- 1mm). The top magnetic section is approximately 3mm thick. *The black upper section (with steel plate) is approximately 1mm thick, and the magnetic sticker is 0.5mm thick. When both are attached, the total thickness is approximately 1.5mm. Compatible with Laptops with Narrow Bezels: The top magnetic plate is extremely thin, only 3mm wide, so it can be attached to computers with narrow bezels. Privacy: The screen appears completely black from angles outside of approximately 60 degrees (30 degrees left and right) from the center of the screen, preventing side views and protecting your privacy. Magnetic: Easy to attach: This magnetic privacy filter can be removed as needed. Includes a wide range of accessories: The included magnets can be used to attach the filter to computers without built-in magnets. (Four magnets are included; normally, two are sufficient, but use all four if necessary. Also included are fixing tabs and double-sided tape, but use these only when necessary.) *Some models may have a slight gap when closing the PC cover with the filter attached, but the sleep function will still function without any issues.

[Reduces Eye Strain] Blue light emitted from laptops is said to disrupt the body's rhythm and cause eye strain. This filter blocks approximately 49% of blue light, making it recommended for those who work on a computer for long periods of time.

[Double-Sided Use] One side of the filter is anti-glare, while the other is glossy. Use the anti-glare side to prevent reflections from sunlight and other light sources and reduce glare.

[Screen Protection] The 3H hardness rating protects your computer screen from scratches and cuts.

[Moderate Transmittance] With a transmittance of 72%, you can wear it for long periods of time without feeling any discomfort. [Great for Business Situations] This filter is useful for business situations such as on the Shinkansen, airplanes, in cafes, and at work, and is used by many corporate customers. *Not compatible with some Lenovo ThinkPad models (ThinkPad X390, Yoga, X1 Carbon, etc.), please note that when the filter is attached, the sleep sensor may malfunction, causing the screen to go blank. In this case, you may be able to improve the situation by adjusting the magnet position away from the sensor.
