Most common reasons for using a foil

There are many reasons for using a fresnel prism. Your orthoptist will discuss with you the reason why you have been advised to use one. The most common reasons are to:

  • investigate whether your brain has the potential to use your two eyes together as a pair
  • stop double vision (diplopia)
  • use alongside eye exercises which you have been given by your orthoptist
  • predict the outcome of squint surgery.

Advantages prism foil

  • Relieves double vision
  • Easy to (keep) clean
  • It is easy to remove the foil after use
  • Easy to change prism strength as your eye condition changes

And disadvantages

  • Prisms creates a natural blurry image, because of the lines that are on the plastic prism.
  •  They have to be fitted onto a glasses lens. If you do not need glasses to correct your eyesight, a pair can be made up with plain glass.
