I started to wear glasses a couple of months ago, after the lenses inside my eyes became less flexible with age and lost the ability to focus on distant objects. My distance vision was probably deteriorating for a year or two before that and probably affected my perception of England. I thought the English landscape was soft and blurry, which I attributed at the time to the abundant vegetation and persistent drizzle. Now I think it was just out of focus!
My specs have given me a much sharper view of useful things like stars and street signs, but they're also proving useful as shields. Last weekend at a party I stood near a fire, and some smoke that blew in my direction hurt my eyes much less than I expected. This evening I sliced some onions while making dinner, and found that I didn't need to submerge them to stop my eyes watering. Four eyes are actually better than two.
One final point: I know some of my relatives have taken digital photos of me in the last couple of months. Could someone send me one of these recent photos to use as an accurate profile picture?
