Just wanted to share I found a good deal on Optivisor (ie.
magnifiying lens) at Overstock . com
Here’s the link:
I got the one with a #7 lens.
Looks like they’ve omitted the knurled knobs at the hinge joints so
you can’t adjust the tension. It won’t be a good deal when the visor
keeps fallingdown on your face after the hinges loosen. Chinese
I found it a few cents cheaper here

These are the LX version, with plastic lenses instead of optical
glass. Cheaper on Amazon.
Also note, you can purchase and change lenses for about $15.
What is the difference between these 2? thx, brenda
