CRT Anti-Radiation/Anti-Glare Filter keeps screen data confidential by making the screen blurry and illegible when viewed from a side angle. When viewed from the front, it is sharp and clear. Filter reduces glare by 99 percent and eliminates 99.9 percent of ELF/VLF E-field radiation. Static electricity is dissipated through a grounding cord to reduce dust buildup and risk of data loss.
