yes my ability to read without glasses went. OMG lol my older freinds told that it would happen and it did. It seems to have happened overnight lol
Mine happened in a single day, or at least how I perceived it. I'd been camping alongide a lake for a week, and drove into town for groceries. First thing I noticed was a STOP sign was blurry. Inside the supermarket I couldn't read the signs over the aisles, to find what I wanted. Yet I could read the labels on the items themselves just fine.
A few days later I was back on base and went to see a military eye doctor, since the problem was continuing. When he said I needed bifocals at 43 I wouldn't believe him, since I could see fine close up, it was my distant vision. His explanation was that my lenses, now becoming inflexible with age, were getting "stuck" in a near vision focus, and couldn't relax to their distant vision state.
Muscles pull the lenses to focus up close, but natural elasticity lets them return to distant vision. Having lost that elasticity, the muscles could still strain to produce close focus, but then the lenses got stuck there, causing blurry distant vision.
It seemed counterintuitive to me, but the doctor assured me that bifocals would resolve the problem. And my eye's lenses would eventually become completely rigid in their distant focus attitude, anyway. And he was right.
