I've been wearing progressive bifocals for about 3 years - almost exactly the same amount of time that I've had a DSLR. I have found that my declining vision creates two problems for me. First, I can't manually focus with accuracy. Two examples:
First image was shot focusing manually, as carefully as I could (with my glasses off - trying to focus photos with the glasses on seems a crap shoot, since the lens varies so much with just a mm of head tilt.)
Sucks. Could have been a good shot if it had been in focus.
Second image was letting Nikon and Sigma do the focusing for me. Note that I had good light, a monopod, and still subjects, so the technology wasn't being challenged at all.
I apologize for the use of non-herp photos. Please forgive me.
Obviously, in the field I can rely on autofocus to overcome my lack of decent vision. Autofocus isn't perfect, but it almost always does better than I can do on my own.
But what about in post-processing? When I sit at the computer a slight roll of my chair or a slight tilt of my head makes a big difference in whether I perceive that a photo is in focus or is a throw-away. I'd hate to dump good shots because my eyes don't see that they are, in fact, in focus.
My optometrist recommended that I get a pair of computer glasses to use at the desk, rather than wearing my progressives. But I hate to spend the money, and I'm sure I'll end up leaving them at the office when I need them at home, and vice versa. So I'm wondering if some traditional bifocals would be better than progressives. That way when I'm looking at the computer screen I know for sure that I'm seeing it through the same lens every time, regardless of where I'm sitting. And I would always have them with me, if they were my only glasses. Computer distance is not necessarily reading distance, so maybe I want trifocals.
So, photographers with presbyopia, what glasses work best for you?
