Over the past few months, I've been doing a lot of close work which has
aggravated my lazy eye (which started when i was 9 and i never got it
treated). I use the term "lazy eye" loosely, as I don't have amblyopia
as such, as the vision in my good eye is actually worse than in my lazy
eye.

I was wearing the wrong rx for the past few months - a diopter stronger
than what i should be wearing.

At a recent eye test, I got the proper rx. And since wearing my new
glasses, i've been having many headaches and squinting a lot, more at
distance than at near. Before with my stronger lenses I was squinting
more at near, as the rx was too strong for close work. My distance
vision is pretty poor now, probably because my lazy eye is not working
and needs to learn how to focus.

the orthoptist did various tests, and I have something called
convergence insufficiency. I got some eye exercises to do to get my
lazy eye to straighten, but the exercises are very tiring as well as
time consuming. Another alternative the doctor suggested is to wear
prisms. This won't really solve my squint, but it will make reading
more comfortable and since I do so much close work, i feel I really
need help to make the lazy eye focus, it often drifts off and I skip
lines and depend too much on my good eye.

Would patching the good eye help while doing close work? Or would a
prism be of real benefit?

Also, should I wear a weaker rx for close work? I can actually see ok
without my glasses for computer work, but get headaches after a while
(astigmatism) so I have to wear the glasses, but i feel i don't need to
be corrected for myopia for near work.

My eye squints more when trying to focus in the distance rather than
near.

I am mildly myopic (approx. -2) and have some astigmatism (-1  to
-1.50).

Any medical professionals out there please help! I'm at my wits ends
trying to find a solution to my problem.

Thank you.
