- I always wonder why more people don't wear hard lenses. They are
- optically superior to soft lenses, correct for astigmatism because they
- maintain the proper lens shape even if your eyes are flat, they don't scratch
- or tear easily like softs, they don't require daily sterilization, and they
- last forever. They also protect your eyes better and the modern gas
- permeables breath as well as softs. The only disadvantage is that it takes
- a few days to get used to them because since they are smaller, your eyelids
- have to jump up onto the lens when you blink, and this is slightly annoying
- at first. After a few days, this is no longer an issue. The small size is
- nice because they are smaller then your iris so you don't get the dorky
- "ring around the iris" look that softs give you.
-
- AND they work fine with the A2E!!!! If we could only get APO
- low dispersion contacts, what a sharp world it would be.
-
- Any comments on the optics of vision correction? It seems to me
- that the lenses we use every waking moment are at least as important as
- the ones on our cameras. Nah!
