The limited viewing angle narrows the field of vision to +/- 30 degrees, helping keep on-screen information private and reducing the risk of visual data breaches in the office or public. Blue light reduction filters harmful rays by up to 22%, easing eye strain and reducing sleep disruption. The low-reflective coating reduces glare for improved clarity.
