You should try coping with a prescription that effectively changes through the day
Last Christmas I developed a Holmes-Adie pupil. My right pupil now has a mind if its own.
Most of the time it stays moderately dilated. This is a pain in bright sun, because it doesn't constrict quickly to adapt to the bright light. It will sometimes constrict a bit after being in bright light for a long time, but usually just as I'm going back indoors...
It also don't dilate beyond a certain point. So my night vision in my right eye isn't as good as my left (which gives a very odd feel in a darkened room).
It also has an odd behaviour late at night or sometimes after spending a long time in a night contrast environment (like looking at a bright computer screen, phone or iPad for some hours). It will suddenly constrict as if I am in bright sunlight and stay constricted for a long time.
Because the amount of dilation of the pupil is effectively the aperture of the lens, my prescription effectively changes during the day. Also, it doesn't seem to be just the depth of field that changes, which is what I would expect. When my right eye is doing its "clamp down tight" thing late at night, all of a sudden my right eye can focus on the TV unaided nearly as well as my left eye can with my glasses on.
All a bit of a pain in the arse, just hoping that the left eye doesn't follow, as it tends to do in 20% of cases
Using my SLR with my right eye doesn't work so well any more. Also in bright sunlight it isn't just that my right eye is dazzled. It actually effects the white balance as well, so I end up with one eye seemingly with a yellow hue and the other with a green hue. All very odd.
