Here's an update to my Feb 9 posting about an eyeglass-possibility on EBAY -------
My vision-prescription changed slightly so I ordered new eyeglasses. I got another big-lens model from EBAY --- my THIRD prescription within this frame in 6 or 7 years. These suit me fine for pool-playing. If you visit EBAY, search for item
263425199280... then click on the description to find info about adding prescription lenses.

The lens height is 52mm. That is about as large as I've seen elsewhere. The TOTAL cost for frame and single-vision lenses was less than $30 so I'm happy --- despite the 30-day shipping wait.
