YMYWorld Magnetic Screen Protector Privacy 3mm for Blue Light Removable 13.3-inch 169 Anti-Spy Filter, Wide, Laptops, PCs, Cut,

[Compatible Models] 13.3-inch 16:9 Dimensions: Filter part only: 294mm x 168mm (Variation in height/width: +/- 1mm) The magnetic part at the top is approximately 3mm thick. *The thickness of the black part at the top (with a metal plate) is approximately 1mm, and the magnetic sticker is 0.5mm / The total thickness when both are attached is approximately 1.5mm. [Also compatible with laptops with narrow bezels] The width of the magnetic plate at the top is extremely thin at 3mm, so it can be attached to laptops with narrow bezels. [Anti-peeping] The screen appears completely dark from angles outside of approximately 60 degrees (30 degrees to the left and right) from the center of the screen, preventing prying eyes from the sides and protecting your privacy. [Easy attachment with magnets] As it is a magnetic anti-peeping filter, it can be removed as needed. [Plenty of accessories] Even PCs without built-in magnets can be attached using the included magnets. (Four magnets are included; usually two are sufficient, but use all four if needed. Fixing tabs and double-sided tape are also included, but use these only when necessary.) *Some models may have a small gap when the PC cover is closed with the filter attached, but the sleep function will work without problems. [Reduces Eye Strain] Blue light emitted from laptops is said to disrupt the body's internal rhythm and induce eye strain. This filter cuts approximately 49% of blue light, making it ideal for those who work on computers for long periods. [Double-Sided Use] One side of the filter is anti-glare (anti-reflective), and the other side is glossy. Use the anti-glare side if you want to prevent reflections from sunlight or artificial lighting and reduce glare, or use the side you prefer as needed. [Screen Protection] With a hardness of 3H, it can protect your computer screen from scratches and cuts. [Just the right level of light transmission] With a light transmission rate of 72%, you can use it comfortably even when it's attached for extended periods. [Ideal for business settings] This filter is highly valued in situations where you use your computer for work, such as on bullet trains, airplanes, in cafes, and at the office, and is therefore used by many corporate clients. *Incompatible models: Please note that with some models of the Lenovo ThinkPad series (ThinkPad X390, Yoga, X1 Carbon, etc.), the screen may go blank due to a malfunction of the sleep sensor when the filter is attached. In that case, adjusting the position of the magnet away from the sensor may resolve the issue.
