Optivisor?

Looking to buy an Optivisor over the internet but not sure what power to
get...I usually wear 1.50 or 1.75 cheaters to read...any suggestions
for what to get to be able to solder those itty, bitty Elecraft parts?

FYI - usually the number represents Diopters, which is the unit used
to express the power of a lens. It is the reciprocal of the focal
length expressed in meters.

A lens with a diopter of 10 would enable your eyes to easily focus at
1/10 meter (3.9 inches). One with 5 would work well at 1/5 meter (7.8
inches), etc.

I'm sure distortion was a bad choice of words; it was not a cheap knock-off. Field of view was far too short with the 4x for me. The 3x has proven to be perfectly usable for me, with a much better field of view. The fact that I'm accustomed to progressives with a high power *may* be a factor here. As I said, I realize a lot of guys like the 4's.

As an aside, I live less than 8 miles from the Optivisor company.

Another word of warning. Optivisors cut off peripheral vision. But I
"knew" just where my soldering iron was. After a 2 hour wait in the
emergency room, the doctor gave me a tube of silver sulfadiazine and
told me to be careful. 700 degrees burns very fast. Usually, I can
adjust the optivisor up slightly, so that I can also see underneath
with glasses only.

I have the same opinion. I bought the 4s because I wanted all the
magnification I could get. I found that the focal length is too close to be
comfortable to me. The view is fine but the work is just too close. I
intend to get 3s and I suspect they will be a better fit for me. Someone
here explained the relationship of the number to the focal length. Prior, I
didn't realize the number was anything but just a number. Thanks, Jim

Re: Optivisor?

At work I use a 3 generally but also have one of the little 2.5x flip
down lenses attached so that I can zoom in closer when I need to. Very
handy.
