This Laptop Privacy Screen is designed to work with your 2021 and 2023 14-inch MacBook Pro. This privacy filter is a convenient and cost-effective solution to protect confidential data from unwanted viewers.

The privacy screen protector is reversible, with a matte anti-glare side for environments prone to glare and a high-gloss side that helps retain color vibrancy. The matte side provides additional screen protection with a fingerprint and scratch resistant coating. The privacy shield has a light transmittance of 60% providing optimal screen brightness and enhanced levels of privacy. Attach the privacy screen shield using the slim built-in magnetic strips. Included protective sleeve to stow away/protect the privacy screen from damage when not in use. Reduce eye strain and improve visual comfort by reducing blue light exposure.
