Someone made mention of obtaining an Opti-visor (SP?) at a
craft store. Another quality brand is made by Magni-Focuser.
This one has a handy feature in the form of a knob at the back
of the headband that allows for easy size adjustment. The
Opti-visor's band tends to slip and work loose.
Optivisor makes a knob-adjust headband too. I have one. At one point I
picked up a second Optivisor so I could leave one at work and it has the
slip-type head band adjuster. Perhaps it was cheaper.
I agree, the knob adjust is worth getting even if it's a few bucks more!
