I've recently developed intermittent vertical diplopia (double vision) - it will happen out of the blue and last for a few minutes (closing eyes and relaxing seems to clear it up). I've been trying to wear my reading glasses more often and also when on the computer and it seems to have largely cleared up, but it still happens now and then. Do you think it's safe to consider it problem solved or should I be looking into it more? Went for an eye exam and she said everything was fine.
Sorry for the late response. I overlooked this. Go see a doctor. Never fuck around with double vision. Especially not with vertical one. And make sure to AVOID horizontal prisms. They never work as a solution except in cases of actual muscle /paralysis/, i.e. via the nerve, and not just muscle "weakness". The muscle weakness theory of strabismus and diplopia seems akin to a load of hogwash, as it fails to pass even the simplest human bioenergetics(and I mean the scientific field that deals with caloric distribution & thermoregulation, not the - unfortunately more well known - hurdur pseudoscience term.) litmus tests:
If given a sufficient nutrient supply and an issue stemming from muscle strength, then exercise alone must suffice to grow the muscle. If the issue stems from muscle length, then exercises alone must have the capability to lead to elongative growth. However, this requires an incentive to LOOK IN THE RIGHT WAY instead of supressing the image. As a theory, it fundamentally confuses cause with effect. Yes of course the muscles become unbalanced - as a CONSEQUENCE of the neurologically originated suppressive (amblyopiatic[sic]) action of averting the gaze of one eye to ensure the brain doesn't have to keep on encountering statistical near misses that waste neurological resources.
If our muscles had some kind of "critical period", then people who didn't hit the gym as children couldn't ever gain muscles in a gym as adults. A clearly absurd notion, thus, via reductio ad absurdum, QED.
Causes of diplopia range from the innocuous to the serious, I would investigate a bit further and rule out the easy stuff (diabetes/thyroid) and stay alert for other possibly related symptoms.
