My safety glasses arrived.
Through the many years I wore only a contact, if anything, my left eye was subjected to no correction. It was very upset when I put this lens on it. It squirmed around. I saw double; things alternated between looking much more clear and much less clear. I don’t know if it is just glasses as usual or because one eye is too nearsighted to pick my nose, and the other is slightly farsighted (overlooking my nose entirely, I suppose), but with the glasses on each eye has a different focal length unless I look straight through the glasses.
Probably this is common to wearers of glasses. I suppose my eyes will be locked looking straight out of my skull for the rest of my life. This is probably why people who wear glasses develop a distinctive sag around their eyes; not a huge sag, but a characteristic softening. The eye-driving muscles are deprived of any function and wither away.
It’s more fun to look at life from all different angles.
