I am a 48 year old woman, who has suffered from nistagmus since I was a child. I saw a specialist at first until I was 18, but then my eyesight had improved enough to see a local doc. Now that I am older, and just started a career with computors ,my eyesight has really started to give me problems, my eye doctor told me I just needed some readers, but I am not sure, because it seems like I have to strain to see anything without them. Can you give advice.
