Over the summer, I had cataract surgery on both eyes. In the process, I went from being very nearsighted (fine for a weaver!) to having 20/20 distance vision but very poor near vision. That's what happens to aging eyes - near vision fades pretty quickly.
The opthalmologist keeps wanting to pigeonhole me in with the older folks who only need to see the TV, the bingo card, and the large-type Reader's Digest magazine. The first pair of glasses with corrective lenses - the pair that Medicare covers (or at least, gives an allowance toward) - had the upper 50% of the lens uncorrected (since I'm 20/20 for distance, right?), the lower-middle 25% set for about 1-meter distance, and the lowest 25% set for reading distance (maybe 16 inches from my nose).
Those are great for the grocery store, because I can see the strawberries at the far side of the produce department, and also read the tiny print on the ingredients list on the cereal carton. Also great for driving; I can see the big-rig truck on the highway, and also the dashboard, all at the same time, just by raising or lowering my head. Works for knitting while watching TV, too. But.
I got the glasses from the Opthalmologist's optometry department a couple of days ago. After using them for several weaving sessions and being very unhappy with the experience, I went back today, armed with "show and tell" consisting of one woven piece (a scarf made of 60/2 and 120/2 silk) and some photos of the looms I work on.
I had to argue with the doctor for much too long before I was able to persuade him that what I really wanted was a pair of glasses for *WEAVING* since I only go to the grocery store twice a week, and weave most of the day every day. He finally relented and designed me lenses that have the upper third of the lens set for about a meter away, the lower third set for about the location of the fell of the cloth when I weave, and the middle third about half-way between the two.
These are "progressive" lenses, so there's no sharp line between the various zones, the magnification just transitions gradually from one to the other.
Anyway, enough rant. These are the "show and tell" photos I brought along. I don't think he had any idea what a loom was, and these helped. I thought you might also be interested...
