StarTech Anti-Glare Privacy Screen Filter for 13.3" Widescreen Laptop (16:9) (133LB-PRIVACY-SCREEN)

This privacy filter is a convenient and cost-effective solution to protect confidential data from unwanted viewers. The privacy shield darkens your computer's screen from the side while providing a clear viewing angle of 60 degrees (+/- 30 degrees from center) to the user. Reduce eye strain and improve visual comfort by reducing blue light exposure. The 13.3-inch laptop screen filter is independently tested by a 3rd party lab to block 47% of blue light in the 380-450 nm range. Digital eye strain can lead to symptoms like headaches, dry eyes, and blurred vision.
