Everytime I read or do close up work, I then have blurred and double vision for about 6 hours sometimes. I do have some type of muscle disease that is being worked up but the neuro-opthomplogist says i just need eye drops. My eyes are not dry at all. Eye drops do help at all. Please help me to find the problem. I will look up any muscle disease that this could be related to to see it I have the other symptoms. My eyes are getting worse and I feel like I may someday soon, not be able to see at all.
