Rereading the thread on shooting glasses, and reading this one this morning, makes me realize that vision problems are various and what works for some of us will not work for others.
While I wear bifocals, I usually remove them for reading or if working on something small that I need to see very clearly. I need to hold the book or item fairly close, but I can actually see more clearly without the bifocals. (I can also see my front sight well without bifocals.)
I should check, but my guess is that I can see my car dash and instruments well without bifocals.
Ya know, writing this, I'm thinking that while I have been wearing bifocals now for 15 or 20 years, what the heck am I wearing bifocals for...?
Since our eyesight changes over time, maybe they made sense for my earlier but no longer do? I think next time I visit an optometrist I am gonna bring this up...
