Wearing an eye-patch.

I have had strasbismus in my left eye all my
life.

And so I look out of my right eye and
suppress completely my left eye.

My good eye (the right) sometimes feels
strained, and so I ask:

Should I wear an eye patch over my right eye
to exercise the left one and also give the
right one a rest?

Please help/

Thanks. I notice the strain when working at
the computer a lot.

I have a flat screen 1280 x 1024 pixels which
I was told was pretty good.

Would there be something about the screen
which would be causing the problem, and if so
can I upgrade to something better.

Seems like it would be quite an unusual patient not to be able to
"see" if he had either dry eye or blephartis. Like doc, is my eye
red?

you probably should not bother. suppression of your left eye prevents
you from seeing double which is a good thing.

I think there's a lot about dry eye that you don't understand.

The precorneal tear film layer HAS a refractive index of its own.
Optimal visual acuity depends on the tear film layer being intact.

People with dry eye syndrome have blurred, and variable, vision very
frequently. This causes eyestrain, tension around the eyes, "foreign
body" sensation, headaches, fatigue, light sensitivity, and a host of
other symptoms.

That is probably true.

The above two I understand.

"HAS" ???

Neil, the refraction index of the tearlayer is nearly the same as is the
cornea and so not that important optically speaking.

However you are quite right in mentioning the importance of this layer
when it comes to vision acuity.
It 'smooths' the optical surface of the cornea epitheliumlayer and keeps
it transparent (among other important things)

Well, the tear film has a thickness several orders of magnitude less
than the cornea, so the refractive index difference would not matter
too much, it seems. No eye model incorporates it, that I have seen.

The thickness of this tear layer is of no importance Don and forget what
I said about the difference in indices between the tearlayer and the
cornea....

tearlayer 1.336
cornea 1.376


The fact the curvature of the front and back of the tearlayer (plano)
are the same as the frontcurvature of the cornea counts.

BTW, a very slim lens is still a lens.

What would it hurt if you switched and see if it helps.
I have had strasbismus for 3 years now due to Myasthenia Gravis. I
usually keep my patch on my left eye since it droops sometimes, but if
my right eye feels strained, I will change it for awhile and it always
seems to help. I then will change it back. I am not going against the
doc's advice, it is good to check out other possible problems too, I
am just going from my own experience.
