more on vision

I had a few comments on my last so I decided to write a new post about it.

Firstly in regard to Elspeth’s comment. I agree that children should wear glasses if necessary. That part of my entry was not clear, I was trying to make the point that I can understand children not wanting to wear glasses because they think it’s uncool. But adults should make decisions on more important things such as what is best for their eyes. There are real reasons for needing eye surgery, if without glasses your vision is so bad that you are legally blind then an ophthalmologist may recommend surgery for that. In cases of extreme vision problems apparently a combination of surgery and glasses is required for good results. I also think it makes sense for people who need surgery for their work, for example athletes such as Tiger Woods. Looking cool is not a real reason for surgery, especially not for the small increment of coolness that some people believe is associated with not wearing glasses.

All operations involve some risk. Risk to your vision is not worth a small amount of convenience and possibly looking cool. Besides, it’s widely regarded that people with glasses are more intelligent! ;)

Shintaro mentioned that there is a risk of retinal damage from being short-sighted. What I want to know is whether the risk of that can be alleviated if you wear glasses all the time? If you wear your glasses everywhere except in bed, in the shower, and in the sento, does that stop this problem? Maybe I should try and wear my glasses for more than the ~15 hours a day that I currently do.

Finally an anonymous poster noted that they didn’t know anyone else who had an optical migraine. My ophthalmologist mentioned that it’s rare to have a migraine that only affects the vision and nothing else. I feel fortunate to have it like that, the list of other migraine symptoms sounds very unpleasant. Of course only having had it once I can’t be sure that next time it will be the same. I might get the nasty symptoms next time. :(

However one problem with what I experienced is that it came on suddenly with no warning. It would be very unpleasant to suddenly lose central vision while driving (I would have to hope that the ability to react to objects without consciously noticing them works well). Fortunately I have only been driving about 300K per month in recent years and I can probably reduce this. So the chance of it happening while driving is quite small.
