bkdo Yeah, this is what I am going to do. Do you wear your prisms constantly or just for computer/smartphone use?

Dominic

In my case, I have BVD that requires me to wear them as much as possible, screen or no screen. I’m actually at the point now where I get a headache if I don’t wear them, lol.

Not sure if your situation is different though, did you optometrist give you any instructions on wearing them?

Dominic That's my rating:
Patch on right eye 1/10
Patch on left eye 2/10
Astigmatism lenses (-0.25 both eyes) 5/10

Sounds encouraging! (the astigmatism lenses result, I mean).

Your lenses have -0.25 correction; could you please also tell me what your eye's astigmatism value is? (based on machine printout and/or based on optometrist evaluation)?

bkdo My optometrist told me to wear prisms only for near vision tasks, but I feel like I should do it all the time. I have a heterophoria both at near and far. As I had my LASIK done 8 years ago I don't want to be prisms (or any glasses) dependent, but what else we can do if vision therapy doesn't lead to satisfying results.

logixoul Based on autorefraction I have -0.5 on right and -0.25 on left eye. I tried three pairs of cylindrical lenses: -0.25 & -0.5, -0.25 & -0.25 and 0 & -0.25. The first ones gave me a headache, the last didn't make much difference.

Thanks!

If I understand correctly (from several of your posts), astigmatism lenses (-0.25 both eyes) make it much more comfortable for you to look at screens (even when taking into account the headache you get from those lenses). Is that right?

Also, did you find any way to (partially or fully) remove the double vision?

logixoul Exactly. Headache I get from lenses is much more tolerable and it starts after hours, not seconds.
My double vision is fixed by astigmatism lenses, but I'm not sure if it's caused by astigmatism. Before I bought a new laptop and all this has started I had never had double vision.

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.

logixoul

This happened to me, but it eventually faded.

logixoul

Sorry to hear that, a break from the patch definitely sounds like a good idea. Have you spoken with an optometrist about the patch at all?

bkdo Have you spoken with an optometrist about the patch at all?

No, I never became certain that the patch helps me in the first place (I mean I couldn't make sure it's not placebo) so I only very briefly mentioned it to my optometrist. He didn't comment on it.

mike Hi,

Yes, I actually continued to patch (barely stopped at all), because the 3 responses to my post sounded very encouraging.

The problem (the "difficulty converging" problem) has almost completely faded away.

bkdo My advice would be to pick the pair that you think provides the most symptom relief

Symptom relief during the actual eye examination? Or symptom relief in the weeks after getting the prism lenses?

logixoul

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.

logixoul astigmatism lenses (-0.25 both eyes) make it much more comfortable for you to look at screens

Dominic My double vision is fixed by astigmatism lenses

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.

AGI I felt relief immediately, however even after months of wearing astigmatism lenses my headache caused by them has not gone away. Prior to the astigmatism correction I had a slight eyestrain when reading on paper, but did not have eyestrain from good screens.

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.
