Abstract: An improved method is provided for applying an antireflective high contrast coating to a lens, as well as a lens system made with said method. By coating the lenses with a mixture of an oxide and fluoride, the transmission of undesirable visible light wavelengths is reduced, as is the reflection of undesirable light. This combination not only increases perceived sharpness and detail associated with viewing objects through the lenses, but also reduces undesirable reflected glare. Utilization of increased vacuum during the coating process reduces problems of humidity associated with plastic lenses. The combination of oxide and fluoride is controlled to reduce colored tint or hue in the resulting lenses. By imparting little to no color hue to the lenses, the lenses virtually eliminate any undesired color shift associated with prior art lenses.
