CI could just be an
Astigmatismor it could be muscle related. My oldest daughter(8) has the misfortune of having my genes, and has thusly inherited my Astigmatism. Basically both eyes see perfectly clearly, but the images don't line up 100% and are thus blurry.
My daughter also has
JRA, and becuase of the possibility that JRA can effect the eyes, we have been going to an eye doctor to have her checked out every six months. When I first noted that she was getting reluctant to read at night, I mentioned it to the eye doctor. He tested her near and far vision and her vision is 20/20 or better. He said to watch it, and he would check her again at the next appointment. By the next appointment she was still having the same reluctance, and had started complaining that reading too much basically gave her a headache. He checked her again, and got the same results. She can see perfectly. I pressed him, because I know what my issues with vision are, and I knew that she was having some issue. He ended up trying the first prism setting, and low and behold, it made the words clearer for her.
I let her pick out the glasses, and she hasn't lost them yet. although she has franctically searched the house a couple of times looking for them. I steered her toward the Flexible frame glasses. That way she can get get bumped into, or otherwise abuse the glasses (like sitting on them) and they maintain their shape.
The dr. seemed surprised that she (a 7 year old at the time) needed the prism lense, and if I hadn't pressed the issue she would still be struggling to read.
As for the actual exam and the dialation. The dialating drop do sting a little if you just put that directly into the eyes, but when dealing with children our doctor put in some numbing drops first, and my daughter didn't feel anything when the dialating drops were put in. Even if they don't do the numbing drops, the sting is no worse that when you touch your eye with a finger, and get a little of the salty sweat onto the eye. you know it's there, but it last only a second. for after the appoint dark suglasses will be need for at least a couple of hours. Our doctor had disposable sunglasses that they gave her. They looked like the 3D theater glasses with brown lenses instead of red and blue... She got a kick out of them, and wore them instead of teh ones we brought...
Hope that helps.
