Hi guys,
I'm glad I found this fourm! Your insights are very interesting. I had strabismus in one eye as a child, which was corrected by surgery. Perhaps working on a computer after age 30 somehow restored my defect, which is hidden now. I have occasionally been told that I don't focus my vision on the speaker. But it happened maybe 1-2 times. Maybe I will go to an optometrist with this idea.
Try to warm your eyelids with a warm towel for 5-6 minutes every night before going to bed and then massage your lower and upper eyelids for 2-3 minutes. How to do it, you will find on the internet. This is not a 100% solution to the problem, but it helped me a lot after a few days.
