Convergence insufficiency (CI). PLEASE, help me!?

As of November 2010 I started having some symptoms like eye strain, pain on my eyes and serious difficulties whenever I tried to read. At the moment, I saw a doctor in order to see what was happening to me. The doctor prescribed me new glasses but it didn’t solve my problem, I returned there twice more and took new glasses and eye drops but it was useless. I still had serious problems to read.
Three moths later I went to another city and saw another doctor. This doctor also precribed me new glasses and told me that the muscles of my eyes were weak. He asked to make pencil pushups and said it would solve my problem. I got new glasses for the third time and started doing the exercices. A month later I returned to my doctor’s office to tell him I wasn’t felling better. At the moment he asked me to make an orthoptic test with another doctor who worked in the same hospital. I did it at the same day but nothing was found. The doctor told me I had tendency to develop strabismus but it wasn’t important and he also told me my problem might disappear in a few months.
After that, I visited another doctor who suggested me to use contact lenses, it was horrible and useless. I also saw general practitioner who discovered that my blood pression was a little high, probably because I get too stressed with my vision problem.
About six months ago I finally found a doctor who diagnosed my problem, convergence insufficiency. Nevertheless, the treatment prescribed by this doctor isn’t working. He asked me to do do some exercises in a doctor’s office and at home too, I did it but it didn’t help me.
I have searched about this disease and it’s treatment. I discovered that some doctors use prism reading glasses, training spactacle lenses ( I don’t know what it is.) and even surgery to treat this disorder. But my doctors say that these methods are not good. In their opinion, orthoptic exercises is the solution for me.
At present I’m doing more exercises in another clinic, actually I’ve done only one session there yet. I’m not sure it will work and sometimes I get desperate when I read about people who are trying to get rid of this problem for 5 years or even more.
It’s even harder for me because I’m a student and the only thing I do is to read. I love reading but my vision problem is stopping me from doing that. If you have already had this problem or if you know someone in anywhere who can help me, please tell me!

Thank you for reading it.

Help understand!?

Please explain wat this means(today!)

When the room light is low, your eye adjusts in several ways. First, the rod and cone cells on the retina begin to produce more light-sensitive chemicals. These light-sensitive chemicals are the first step in detecting the light, converting it to an electrical signal and transmitting that electrical signal to the brain. Second, the iris muscles relax, which causes the opening of your eye, the pupil, to become very large. This allows your eye to collect as much light as possible. Finally, the nerve cells in the retina adapt so that they can work in low light. These three changes take about 20 minutes to 2 hours, but they increase your sensitivity to low light by about 10,000 times.
When you read, your eye must be able to focus an image of the words onto your retina. To do this, the iris, as well as the muscles that control the shape of your lens, must contract to keep the focused image on the retina. If you read in low light, your visual muscles get mixed signals: Relax to collect the most light, but at the same time, contract to maintain the focused image. When that object is poorly lit, focusing becomes even more difficult because the contrast between the words and the page is not as great, which decreases the eye‘s ability to distinguish visual detail. That ability is called visual acuity. Your eyes have to work harder to separate the words from the page, which strains your eye muscles. Consider this to be strenuous exercise for your eye muscles. So your eye muscles will ache, much as your arm muscles and leg muscles become sore after strenuous exercise.

When your eyes are working this hard for a long period of time, the strain may cause a number of physical effects. Symptoms of eye strain include sore eyeballs, headaches, back and neck aches, drooping eyelids and blurred vision. Because you often don’t blink enough when focusing on a single object, you may also experience uncomfortable dryness in your eyes. None of this damages your eyes, and all of it eventually goes away after you stop straining them. Many eye doctors leave it at that, but some note that eye strain may contribute to nearsightedness. Most people who are nearsighted were born that way, but there is evidence that prolonged eye strain can make it worse.

If you are comfortable reading with a flashlight (or other low light) and don’t experience any of the above symptoms of eye strain, it’s probably fine for you to read this way. It’s certainly easier on your eyes to read in good light, however. You can also avoid eye strain when you’re reading by blinking frequently and taking a moment to focus on something out the window or across the room every 15 to 30 minutes.
