Bangerter Occlusion Foils

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.
Foil size is approx. 2.5″ x 2.5″
Recreational Use: Used in shooting sports – Instructional and Competitive Shooting.

Bangerter Occlusion foils are a system of graded thin flexible patches of varying degrees of transparency that equalize the spatial contrast of the dominant eye.

Application Instructions:
  • The shiny side of the foil is applied to the inside of the lens.
  • Cut the lens with sharp scissors to fit within the frame or fit the area needed.
  • Slightly dampen the shiny side of the foil with warm water and 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.

Removable and Reusable, similar to a window cling on.
The more often it is removed and re-applied it will gather oils and dust and will not stick as well.
Expected life of a foil will depend on how often it is removed – one -two months if it is not removed, less if it is removed daily.
NOTICE: The duration of the adhesion of the occlusion foils can be limited when used on lenses utilizing nano-technology (such as but not limited to Crizal lenses).
