squidward_eyes_93 You should definitely give vision therapy a go. You may get rid of the prisms. See an orthoptist or a behavioral optometrist 🙂 Finding a fix for your eyestrain may not be straightforward, though. As you said, heterophoria may not be the only cause of our problems.

      AGI ok! thank you so much! 🙂 ya I think I need someone to give me a little gentle push and encouragement to sign up for vision therapy, and feel optimistic about it. I definitely feel so much more energized to take on this challenge...In fact I might call the office today lol ya definitely not straightforward…I used to cry about it, but lately things are on an upward trend; though with setbacks as well. glad I could share this with someone who understands. means a world to me.

          squidward_eyes_93 Vision therapy requires only a few minutes per day. I do it a few minutes every day multiple times per day. It helps releasing some of the strain. Worst case scenario it won't (completely) fix your problems, but will make your eye muscles more balanced.

          I understand you. Best to fight back and stay positive. Getting depressed does not help.

                What kind of exercises were/are you doing? Are there any materials online?

                    karut Please see here for example. If you are not familiar with vision therapy and do not know what condition you have, you need to get advice from a professional, though. My exercises may not be adequate for your condition.

                        AGI Thank you so much AGI! I think you helped me try again. I have been falling off of my at home vision therapy routine lately lol

                          AGI I have vision therapy exercises where I make myself go crosseyed until two images become three. Is that enough?

                            My opinion is to change all the light fixtures in your house in places you commonly stay in to be PWM-free, and also change jobs to be in an environment with no PWM.

                            This is what I've done and I basically avoid places with PWM lighting and it's worked out okay for me. My devices include iPhone 8 on iOS 14.5.1. iPhone XR on iOS 16.2. Asus PG248Q on windows 7 still. They are all okay. As for the lighting I use in my home, I posted about that in another thread regarding flicker-free lighting: https://ledstrain.org/d/1176-flicker-free-led-lightning-its-the-most-important-thing-which-one-to-buy/55
