Hi
I passed a full flying medical in 1955. In 1957 when TV started I noticed that I needed to sit closer to the TV to stop blurring. I diagnosed slight myopic condition and had my eyes tested. Glasses fixed the problem.
By 50 I noticed that there was a shift in my vision and glasses were no longer necessary for long distance under good lighting conditions. I had my drivers licence so endorsed. This is a vision shift I already knew was a common result of myopia.
By 55 I found I needed glasses for close work and had my eyes tested again where glasses were again prescribed for reading. This also fixed the problem of difference in the focal range of each eye.
At 76 I now need glasses for close work (reading etc) and distance for night driving. (if I remember to bring them). I don't use glasses for normal vision or with a telescope.
As a couple of side issues. a friend of mine (about 40 years ago) had trouble parking his car near the curb and other close objects. Being a smart arse I diagnosed astigmatism and suggested that he have his eyes tested. He did, got correcting glasses and now has excellent depth perception. The other point is I went to a 3D movie yesterday (The Green hornet) and with the polaroid? glasses I had great 3D effect.
