What a concept! I had never heard of piano glasses. I knew about reading glasses (been using them a bit longer than I care to admit) and computer reading glasses, but piano glasses....interesting. The idea of having glasses especially made for the piano has stayed with me and I started to do some research into the idea. I found that the traditional distance for reading glasses is about 14-16 inches and the distance for computer glasses is about 18-20 inches. So, I sat down at my piano (using proper posture) with a tape measure and found my piano music reading distance to be 22-24 inches. That is significant focal length difference and will definitely impact an eye prescription. (Here's a pretty interesting article for optometrists on eyeglasses for musicians.) I imagine this difference can vary depending on the individual, so it is probably important to measure yourself at your own piano.
So, I have been noticing lately that my own eyes have been changing a bit with respect to my reading (and piano) focal length. It has been harder to practice my own music because the musical notes have become a bit more blurry. So, I'm going to have to schedule an appointment with my optometrist for a new glasses prescription and this poses a bit of a dilemma. Glasses are expensive, should I get a pair of reading glasses and a pair of piano glasses? Upon reflection, I think I'm probably going to get a new pair of blended bifocals and a separate pair of piano glasses, which means I'm buying an extra pair of glasses. However, I love my piano, I think it will be worth it.
Just be aware that progressive (what you called blended) glasses can cause the sides to be blurred. There is some expensive intellectual property out there to reduce it.

ReplyDeleteI used to pay a lot for custom reading glasses. But often scratched or lost then.
ReplyDeleteNow I get them at CVS in 3 packs. Very cheap. And toss them every month or so once scratched.
My point here is even if you want custom prescription, you can very cheaply try different strength reading glasses from local drugstore for a few bucks each. So suggest you try that. Just get your prescription from optomitrist, then buy that strength, then some others in steps of .5 or .25 less power.
Sounds like your prescription is in the range that is sold at the drugstore. That's handy. I rarely wear contacts these days, so I believe my prescription wouldn't be available at the drugstore. However, Readers.com does have a lot of strengths.
