I’ve got some rimless eyeglasses bought years ago from Zenni that I love and that are in perfect condition w.r.t. the frame, but need new lenses. Zenni won’t sell me the same ones again for some stupid reason (something about reducing the allowed Rx strength on those frames due to customer feedback).
Anybody know a good place to get eyeglass lenses by themselves, so I can cut and drill the damn things to fit the frame myself?
(Note: I’m sure it’s possible to have a brick-and-mortar eyeglass shop do it for $$$$$, but I’m cheap, so no.)
Indeed. A long time ago I worked as an internship in one of those places, and cutting the glasses requires special equippment to follow the sample shape and get rid of all the fine dust that is produced while grinding them down. But the work done is usually quite cheap compared to the cost of the glasses themselves, so that is definitly not something I would DIY.
How does the process change when they’re rimless glasses (so the only things I need to be concerned about are getting the pupillary distance and axis right, and then drilling a few holes in the correct spots – the edge is just flat-ground instead of a V-bevel and can be whatever arbitrary shape I want)? Surely that reduces the need for a fancy shape-copying machine, right?
For rimmless glasses they have shapes supplied by the frame manufacturer that the machine can follow. But usually the shape isn’t that important for rimmless glasses so they can likely find a shape in their stock that is similar enough to your current glasses shape.
