Abstract
Very thin films of liquid anti-reflection materials are applied to optical substrates to increase effectively visual clarity and visual acuity by reducing reflection light losses, reducing internal reflections and increasing light transmission. The primary properties of the materials which are useful as anti-reflection films are characterized as non-volatile, optically clear liquids having a refractive index less than the refractive index of the optical substrate to which they are applied. Low cost, effective anti-reflection coatings are thus applied to optical substrates, such as eyeglasses, using a single liquid layer of the anti-reflective material.
