Abstract: The present invention relates to an optical filter including a flexible, transparent substrate coated with a novel combination of optical coatings, and a frame system designed for mounting the optical filter to a television or other visual display screen. A neutral density contrast enhancement is included within the composition of a flexible substrate, or is coated on either the front, the rear, or both of the surfaces of the substrate. A silicone anti-glare hardcoat is applied to both the front and rear surfaces of the substrate. An anti-reflection coating is added to the front surface of the substrate, preferably via sputtering, and designed to reflect a specific color at a preferred brightness measurement. The combination of a front surface anti-reflection coating, front and rear surface anti-glare coatings, and a neutral density contrast enhancement, eliminates the need for an anti-reflection coating on the rear surface of the substrate.
