I didn't know you wore glasses Eclair.
Apparently I should have always worn glasses. My eyes have to work very hard to focus on anything apparently, which I never knew. I found this out about 4 years ago, and the optometrist was amazed that I'd gone through life with no headaches and even made it through school...especially liking reading and art. So, when I got glasses, he didn't give me the actual prescription strength I needed because he wanted me to still work and exercise my eyes as long as possible and not wear them all the time, only for reading.
But now, I simply must have them for computer, reading now and I suspect driving, but have fought wearing them driving, to keep exercising the muscles. Whereas 4 years ago, I didn't, or at least my eyes worked well enough to cope. Unfortunately I read a lot, a hell of a lot for work, and I know my sight is deteriorating fast now.
I remember getting killer headaches in school when I was due for a prescription change. It is quite something that you went all that time without glasses though you needed them.
My major issue now is with prismatic lenses. I have an appointment on Saturday and I bet the prismatics need to be stronger again. My left eye is lazy and just wants to go wandering.
That's what my optometrist said. He asked me several times about headaches etc, that it was quite unusual for someone of my age to have been able to have coped, plus reading and fine art for so long without side effects.
The other thing though is I have a high pain threshold, which can be problematic. This led to me for example to go to the dentist after feeling a little achy, and at the insistence of my partner, only to lose a tooth. The dentist was completely amazed that I hadn't had it seen to sooner...like you just don't get to this stage without major pain.
Same when I had my kids. And that process in itself was bizarre.
