Bangerter Occlusion Foil Light Perception

Bangerter occlusion foils are translucent, plastic filters that adhere to the back of a spectacle lens with only water. They block light transmission and reduce visual acuity in a graded fashion. Foils may be cut to fit most frame sizes and shapes and adhere to existing lenses with only water.

Application Instructions:

• The shiny side of the foil is applied to the inside of the lens.
• Cut the foil with sharp scissors to fit within the frame or fit the area needed.
• Slightly dampen the shiny side with warm water & apply to the inner side of the lens.
• Use a dry cloth the gently remove any air bubbles and remaining water.
• Allow to dry for 1 hour.
• Foil size is approx. 2.5″ x 2.5″
