If you see someone with their head under the cloth and their glasses dangling out held from holding the temples in their teeth, it's probably me or another nearsighted presbyopic photographer.
That might be me. I've been reading without my glasses for quite a while now, and using a pair of glasses just for PC (too much time spent in a photo forum). But my ophthalmologist now says I'm starting to develop a cataract and should consider laser surgery. My wife will have that done to both eyes in the next month or so. Old age is hell!
