Day 16 : Someone or something you definitely could live without.
Hmm. This is actually harder than it sounds. But, after some consideration, I could live without my nearsightedness and astigmatism. I started wearing glasses in the third grade and they were real “glass” glasses. My eyes got steadily worse and I changed to plastic lenses because the glass ones were becoming too heavy.
For awhile in high school I wore contacts — hard ones, because back then only hard ones could be used for astigmatism (I understand it’s different now). I didn’t continue with contacts for two reasons: one, they hurt my eyes and I couldn’t seem to adjust to them, and two, my face felt naked without the glasses. I guess after wearing them for almost ten years, they seemed like a part of me. I only took them off to swim or sleep. Sleeping without glasses had an interesting effect — all my dreams are blurry. I wonder if that is true for others — anyone else experience that?
Currently, my left eye is twice as bad as my right one — about -8 diopters for the left, -4 for the right. That’s just the myopia correction, of course; I don’t know what the astigmatism correction is. But I don’t think my astigmatism is bad.
This picture shows how glasses correct for near-sightedness. The concave or minus lens focuses the light onto the retina instead of in front of it (a convex lens would correct for far-sightedness). Astigmatism is a little different because it produces more than one focal point, due to an irregularly shaped cornea.
