Protect your eyes from harmful blue light and UV rays with this 2-pack of GHY universal anti blue light screen protectors. These screen protectors are designed for 23, 23.6, 23.8, and 24-inch monitors (measured diagonally, without bezel) and feature a hanging type attachment for easy installation. They filter out up to 90% of blue light and 99% of UV rays to help reduce eye strain and fatigue. The protectors are also glossy finish, with 8H hardness for scratch resistance. [Note: These protectors reduce glare from the monitor only, not glare from surrounding light sources.]**
