[Elecraft] Changing the power of an OptiVisor

[Ron D'Eau Claire]

Several people mentioned the issue of getting the right magnification with
an OptiVisor. I found mine in an Hobby store, so I was able to try them on. 

You can vary the magnification without buying new lenses. Like most of us
over 40-something, I have "presbyopia" (old eyes) that won't focus up close
any longer so I wear reading glasses. They work very well under the
OptiVisor. In fact, it's designed for them. I have a 4 diopter lens in my
OptiVisor, and I add or remove my reading glasses as needed for more or less
power. If you have bifocals or graduated lenses, you can get graduated
magnifying power the same way! 

If you don't need glasses, reading glasses are available in drug stores,
book stores, etc. that will do the trick. Get good ones that have decent
lenses. Ignore the looks from the clerks as you try them on under the
OptiVisor in the store!
