martin Thank you for your really detailed posts about what helped you martin! Now that you believe you're on the right track, please don't forget about us! Please give us a 1-month progress check, 3-month progress check, 6-month, etc, via calendar reminder if you have to, just to ensure that it's not just another red-herring!
I believe I have a similar source issue as you: convergence insufficiency & accommodative insufficiency. My eyes look fine, and I don't have any lazy eye or anything like that, but they are a bit wide-set, and may have a bit mroe trouble converging at near than a general control. Earlier you were saying convergence excess though, which is the exact opposite as convergence insufficiency, so I just want to make sure which one is correct in your case.
I just had my annual eye exam on Tuesday of this week. I also want to stress again what martin was saying. The problem is not one of vision acuity. Every year, with corrective lenses (either spectacles or contact lenses), I have 20/20 or even in some cases 20/15 vision. The issue is long term comfort in focusing at near (arm's length). This is more to do with how the two eyes team up to create a fused image that your brain processes.
It's unbelievable seeing the war between optometrists & ophthalmologists on this issue as well. It seems they believe two different schools of thought. Optometrists (if you get a good one) believe the issue may be due to binocular vision, and may do a "binocular vision assessment" on you and determine if you need prisms in your glasses, or binocular vision therapy. Ophthalmologists on the other hand will just believe you have dry eyes. It's pretty unbelievable that they spend 12 years at university to come up with a diagnosis that is so wrong. Don't waste your time. Go to an optometrist and ask for a binocular vision assessment (convergence testing, accommodation testing, etc)
If at all possible, I would like to try beating the source of the problem through binocular eye exercises. When I first presented my big issues in the fall of 2012, I couldn't keep that ruler with the E on it together and fused at my optometrist's office if my life depended on it. On Tuesday, it can pretty much nearly touch my nose and I still have it fused. The convergence exercises I did over the years made this possible. My challenge still though is holding this fusion for several hours a day I spend using a computer. Long into a work day, I will still have the issue of my eyes getting a bit tired, and my fused vision will get a bit "jumpy" (incidences of suppression)
martin, can you explain a bit more what makes these new glasses of yours so special? Do they use extra prisms to help with convergence and/or accommodation? If I find over the months/years that I can't quite get where I need to be with the eye exercises, I will resort to "cheating" and getting glasses that do it for me! 😉
