My MIL just told us last night that she has a "lazy eye", and has had it since she was 8 years old (she is in her late 60s now). The doctor gave her a "prism" placed on one lens of her eyeglasses, which looks like a film that makes one eye "work harder" to see through it.
What exactly is "lazy eye", and what is the technical term? I assume there are different degrees of this, as no one knew she had it. (Her diabetes may be making it worse, which is why it is just now being treated?).
Would love to find more info about this, and hear others' experiences.
thanks!
