ha. speaking of blessings
you cannot imagine how much of a blessing it was to have received that two-letter diagnosis (excess convergence) from the optometrist.
I have spent all week -killing my eyes- reading medical journals about excess convergence and related symptoms. This is something which I could not have done with the cliched term 'eye strain' which, except for the account of my subjective experience, is all I've had to go by. Actually, I never looked at a medical journal before - the inspiration for doing so now has been the amount of responses to my query from "pay per article" medical journals in Google searches. Luckily I miraculously managed to remember my university student number (password too); and furthermore-fortunately they have not kicked me out of the system yet so I can access many of the articles.
I have been learning so much!
After having tentatively diagnosed myself with "ill-sustained accommodation", I decided - upon recommendation of articles - to visit a vision therapist.
I went to the "vision therapist" - actually also an optometrist - told him the previous optometrist's diagnosis, to which he scoffed (later admitting that it was part of the problem, but a symptom not cause), and then I hesitantly told him my own. After a little while he had diagnosed me with "accommodative insufficiency" and prescribed a new pair of glasses - no mention of vision therapy.
Unfortunately I did not like his manner, and he had not explained to my satisfaction why I needed the particular glasses he prescribed - there was some funky logic in there- though in the end he may be right.
Nevertheless, "accommodation insufficiency" does concur with my own subjective feeling of what occurred to me when I tried to read a lot "It feels like I am (or at least one of my eyes is) looking beyond the page, and I have to keep trying to bring the focus back": in this case the ciliary muscle (which is responsible for adjusting our "inner lens") is incapable of sustaining focus on close objects, its' focus lands "behind" the object - where less muscle tension is required; the eyes then overly converge*[this is a highly dubious point!! - I am not sure of the relationship between vergence/accommodation] in an effort to focus on the correct plane(perhaps using the cornea for magnification?? - not sure)- this leads to strain on two different muscle sets, one caused by the other.
I haven't quite worked out the convergence bit yet.
According to anonymous optometrist on the internet "There are LOTS of doctors (99% of opthalmologists and probably 33% of optometrists) that have not been educated to be able to diagnose these problems." Yet, the articles I have been reading state that they are some of the most common issues!??*

Now I have an appointment with the original optometrist who I prefer because he makes a greater effort to explain things to me, is not arrogant and does not make spurious analogies; basically I feel more comfortable with him and trust him. But perhaps I will cancel the appointment.
I still feel vision therapy is what I want to do, it's just a question of finding someone reputable, and not too expensive. Or finding a suitable internet site, specific to my condition. But we shall see.

[* correction, insufficient convergence is one of the most common, insufficient accommodation is less s0- though often they occur together]
