Are prisms in glasses allowed?
Just wondering if anyone can answer the above.
I have unequal refractive error, (one eye is -50, the other -3.50), which when corrected, can cause some difficulties to cope with for a length of time.
Use of a prism in the -3.50 lense stops this difficulty, without altering the refraction used.
I know prisms are normally used for strabismus, (squint), but I do not have this disorder, just the anisometropia, (unequal refractive error).
Is there anyone on the board, (AME, or otherwise), who knows if the CAA have any regulations regarding prism use?
