This usually does nor come on immediately. It happens when I am using the computer, and sometimes when driving, watching a video or reading for extended periods of time.
My ophthalmologist has diagnosed dry eye and prescribed artificial tears, but I am skeptical. It is only in the left eye and only when I focus. I can eliminate the problem by wearing an eye patch. Can you imagine what my employer would say first day on the job? Ho, Ho and a Bottle of Rum!
There is a test for dry eye called the Schirmer test, among others. Might want to take this to rule it out. Don't know if there is a test for eye muscle fatigue, which is more what I suspect. Another physician (not an ophthalmologist) suggested the possibility of a nerve (leading to the eye) problem which could be detected by an MRI, if nothing else makes sense.
Has anyone experienced this? If in the affirmative, what was your diagnosis and how did you get rid of the problem?
I am thinking disability and/or workers comp (computer vision syndrome - CVS). Anyone would be crazy not to avoid additional pain, which could morph into permanent, 24-hour pain for the remainder of one's life. This might be worse than going blind.
