Medical Forum / General / Vision / June 2008Wearing 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/ > I have had strasbismus in my left eye all my > life. [quoted text clipped - 8 lines] > to exercise the left one and also give the > right one a rest? The poor vision will create more strain. Unless you are under the age of 12, patching the right will not improve the left. The right eye strain is more likely related to a right eye problem, not the strabismus. Have an eye exam and ask the doctor to check you for dry eye and blepharitis.

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.

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. > I think there's a lot about dry eye that you don't understand. That is probably true. > The precorneal tear film layer HAS a refractive index of its own. > Optimal visual acuity depends on the tear film layer being intact.

Neil Brooks schreef: > The precorneal tear film layer HAS a refractive index of its own. > Optimal visual acuity depends on the tear film layer being intact. 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) Jan (normally Dutch spoken) > > The precorneal tear film layer HAS a refractive index of its own. > > Optimal visual acuity depends on the tear film layer being intact. > > Neil, the refraction index of the tearlayer is nearly the same as is the > cornea and so not that important optically speaking. 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. Don W.

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. Jan (normally Dutch spoken) BTW, a very slim lens is still a lens. > I have had strasbismus in my left eye all my > life.

[quoted text clipped - 10 lines] > > Please help/ 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. Billy Hey, From my personal experience you try out isotine eye drops, which is ayurvedic preperation and 100% safe to use. Won't leave any side effect, if no improvment stop using aftr a month... but i have used it and it is really effective. for more details about isotine: http://www.isotineeyedrops.com/
