Really, is this an eye test???
I don't know how big your monitor but mine makes this twice actual size.
I bought a Bluetooth headphone set. It is a neck band that sits on my shoulders around my neck. The wires that go to the earpiece retract into the neck strap part for storage. It seems to be a nice enough setup. But the instructions were set up and designed for a nice 8.5 x 11 page but printed in a teeny tiny booklet. The fonts are 6 point or smaller. I have pretty good eyes and with my bifocals I can just read it. Dang. It was easier to use a magnifying glass. If I was really trying to read it, I would download the manual and view it on my computer.
They are nice for long phone calls so I don't have to have the phone to my ear. A can type and talk. Or listen to music while mowing the yard.
