Fakman As far as I'm aware, eye patching is used (on a short term basis) to help treat conditions such as amblyopia, strabismus, & double vision experienced during ocular myasthenia gravis.
It's important to note that no clinical research on patching healthy eyes/vision, exists. So the long term effects are unknown. (This doesn't apply to those already diagnosed with an eye condition/injury).
However, it's reasonable to assume that prolonged patch use may result in conditions such as hyperopia, myopia and anisometropia in the dormant eye, especially if one is patching for 7+ hours a day (average work day).
Although this can be mitigated if one is regularly alternating the patch over each eye.
Either way, if patching, it's vital to monitor any vision/health changes through routine appointments with an optometrist/ ophthalmologist.
In my view, I refuse to use an eye patch just to use certain digital equipment. Both my eyes & vision are currently in good stable condition, as determined by my opthalmologist.
I can read books, newspapers and small text comfortably on paper, and i can see physical objects near and far, with and without the use of prescription eyeware. I've also been able to use certain digital displays in the past, without any trouble, and presently, I can use certain (although limited) LCD displays quite comfortably.
I know my eyes and vision are not the problem here, but the actual display tech itself is.
I'm not prepared to patch, and I'd rather find and use a display that's comfortable for my eyes, as I shouldn't have to subject myself to any risk.
However I fully sympathize with and understand those that patch for employment purposes, or those experiencing extreme difficulty finding any comfortable display without patching. I can only suggest regular routine visits with an opthamologist/optometrist, and discussing the matter directly with them if any changes in the patched eyes are noticed.
