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

- 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.
