Tired eye, plea for help!

Hi, I am a student in engineering. I really need good vision to do a
lot of paper work and computer programming. However, about 2 years ago
I started experiencing tiredness in my left eye. The problem seems to
be always present, regardless of my actual tiredness (it is there when
I wake up as well as before going to bed). My eyes acuity is pretty
good and I don't wear glasses (I had a recent checkup), but I feel my
left eye is constantly tensed and tired. I think the problem is
muscular. My right eye feels perfectly normal and relaxed. This
problem is bothering me to the point where I have trouble
concentrating when reading or even talking with people. I sometimes
even suspect I have ADD. I don't like reading for a long time anymore.
During exams at school I take more time to read the questions and that
result in me being slower to answer. On the morning, I don't really
enjoy reading newspapers anymore. I really don't know where that
problem is coming from. When I mask my left eye with my hand and look
around only with my right eye, it feels normal. But when I do the
opposite (looking only with my left eye) I feel somewhat dizzy and
it's like I have a less good global vision (not taking about acuity,
but rather how I "sense" every objects in the room). BTW my left eye
is dominant. I had an injury 2 years ago in the left eye but it
resulted in nothing serious. Essentially, I was hit in the eye and it
was black and swollen for a couple of days. I also had scratched
cornea. I went to an opthalmologist but he checked my eye and
everything was alright. At beginning my vision was blurry but went
back to normal after 1-2 weeks.

I think my problem is related to muscular soreness. I always have a
feeling of tightness that seems to come from inside the eye.

It may also be related with some photophobia. I noticed I feel better
when wearing sunglasses.

Or maybe I just don't get enough sleep, but usually I sleep at least
8h per night.

Anyway this is a really annoying problem that has been going on for
way too much time. It has deep impact on my whole life. Please help,
any suggestions appreciated, like off the counter products etc...!

 

Thank you for the suggestions. I am wading through my options.

Ok. From what I have read of presbyopia, it causes an inability to focus on
near objects. I have an inability to focus on far objects at certain times
and under certain conditions.

I realize presbyopia is caused by a relative inflexibility of the lens, and
I would believe that could cut in either direction (near or far), if that is
what you are suggesting.

I may ask for clarification later. I have promised my wife I am going to
stop obsessing about my eyes for a little while. (A promise I am partly
breaking just by responding, oops.) I will return to figuring out what I'm
going to do in a week or so, perhaps in a less frantic way then.

Reasonable advice.

Thanks for your input. I may be back with more questions later.

Yes. When nearsightedness worsens at your age, one has to at least
suspect presbyopia to be part of the problem. And yes, it can manifest
as a problem seeing both near and far, with the best acuity in the
mid-range. That is what happened to me.

But everyone is different. A VTOD whom I admire and respect once told
me, "Don't give everyone else your own visual system." I think the
meaning of that is pretty clear.

Cheers,
