Hi Sharron and all -
I also have been using regular prescription glasses which are
stronger than my regular reading glasses and haven't used my
optical visors since. But now I wonder why everyone doesn't do
this> What are the reasons people actually use the visors as
opposed to eyeglasses?
One thing different about the optivisor is that it allows us to wear
our glasses at the same time. It magnifies over the prescription
glasses correction. This allows me to have optivisors in several
strengths for different needs - rather than several pairs of
prescription glasses.
Not everyone has simple prescriptions where the eyes are the same to
be able to just buy stronger reading glasses (which are not made with
safety material) at a drugstore. My (progressive trifocal)
prescription glasses are made with the polycarbonate lens for safety
and they cost about $200+. Never needed glasses until my 40th
birthday. Started out using the cheap “readers” and now, it seems
that my prescription changes every other year - and that gets costly.
Also, I seem to have missed it in this string, but, optivisor makes
lenses in glass and, recently, I noticed they are using plastic for
lenses as well. I’ve always used the glass ones and they last
forever. Fortunately the parts are repairable or replaceable and we
can just pick up and swap a new strength of lens when needed.
I felt really weird when I started wearing the optivisor back in the
70’s - but, now I feel naked working without it. I’ve gotten used to
the scratches in metal looking like canyons. 
They still do the
job - so, I’ve never invested in a new system.
Aloha,
