Posting this simply as an interesting data point:
Been patching for, um, about 2 weeks, and now I have a problem:
When I'm not looking at a computer screen, my eyes take longer (or it is more difficult) to converge to a single point. For example, 0.8sec versus the 0.2sec that is normal for healthy people.
It's not in any way a serious problem at this moment, but I'm wary of it getting worse, so I'm stopping patching for now.
I know another poster in this thread had a similar experience. 
In my case, I didn't really notice relief during the exam. I did notice that my flicker symptoms were reduced within 2-3 days of getting the lenses though. I think the best thing to do would be to try a pair of prism lenses and see how they affect your general eye strain as well as flicker symptoms, and then go from there 
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.
I have -0.25 astigmatism in my left eye. I have known for 10+ years but never tried glasses until a couple of years ago. I got a pair with astigmatism correction, a pinkish tint and blue light filter. I gave in 2-3 days later because of intense headaches and extra eyestrain even with screens that I could tolerate prior to buying the glasses.
I now got the doubt that I did not wait long enough. Questions. Did your eyes have to adjust to the new glasses or was the transition smooth? Prior to the astigmatism correction, did you have eyestrain when reading on paper as well?
logixoul When I'm not looking at a computer screen, my eyes take longer (or it is more difficult) to converge to a single point. For example, 0.8sec versus the 0.2sec that is normal for healthy people.
I too developed side effects from extreme eye-patching (many hours a day) while being subjected to intense eyestrain from new devices / LED lighting (I should add sleep deprivation). While my orthoptist, whom I am due to see in three weeks, told me that I could use an eye patch as long as I wanted, an optometrist recently recommended to avoid it. I will check again with the orthoptist on risks and benefits.
mike Same experience. Now that I 3 months ago started to have problems with ALL displays, like TV as well, patching my right (non-dominant) eye helps if not removes the issue totally.
What is interesting is that I have tried to use my wife's OLED phone with 240Hz PWM eye-patched, and it does not either cause any discomfort.
So it is BVD or some spasm related, not a windows or display driver version problem for me. Hoping to get the problem that started 3 months ago to the level it was when I was able to tolerate some non-PWM screens.
I have been either patching or closing my right eye for awhile now, and have noticed a decent reduction in eye fatigue with several screens.
Last time I went to an optometrist, many years ago, I had perfect 20/20 vision. I'm only in my 20s and still don't need glasses.
Just how often are screens dangerous enough to harm binocular vision, or vision in general?
From what I've read here, many of you have had vision problems for most of your life, but that's not me. I'm concerned certain screens are not just fatiguing my eyes, but damaging them as well.
I haven't had any noticeable issues with double vision or depth perception, but I want it to stay that way.
eyepatching is +1 confirmation for the dithering 'magic eye' fake 3-D problem hypothesis.
I sill patch daily and to date it is the only effective treatment for me. I have been patching for a little less than a year, and I can tell that it is improving my resistance to screens even when not patched. My hope is after 3-4 years of patching, i may be unaffected
I have to say, over time, I am absolutely noticing a difference in my ability to tolerate Windows 10 without the patch. It is definitely increasing. It is agonizingly slow progress, but it is definite progress. The patching does seem to be training my brain to overcome my BVD. I can't believe it.
If after a few years this cures me ... just to think ... 20+ years of agonizing pain, flying all over the damn country to every specialist and snake oil salesman promising me a cure, a literal case in my closet full of useless lenses, devices, eye trainers, gels, creams, pills, filters, over $25,000 spent on this hellish journey ... and the cure turns out to be a 99 cent paper eye patch. I wouldn't know whether to laugh or cry.

Do you mind sharing specifics, like you can go 30 minutes without the patch whereas before it was intolerably etc? Would be interesting to see. Glad you are a feeling better.

You are helping lots of people here. That won't give you the $25k back, but I hope it gives you some solace.
Probably a stupid question and may have already been covered and I've just not seen it….(no pun intended)
After trying a brute force method of tolerating things which is not reallyt working I've got a couple cheap eye patches but how do I know which eye I should be covering?
I believe I have slight astigmatism in my right eye, so would my left eye be dominant?
Or should I be doing one eye for a little while then swap to the other?
