Curious....

Hi,

I know I can probably look this up on google, but I am just curious as to why someone may need a prism in their eyeglasses. I didn't see it often when shadowing...

Thankyou

LOL. Ok....

Usually they're for some type of eye muscle problem that is causing the patient eyestrain or double vision.

You'll learn ALL about prisms when you take optics in OD school!

Haha, just learned that today! Double vision...it shifts the image so it focuses on the fovea rather than some other area in the periphery.
