I lost a pair of eyeglasses and contacted the store from which I bought them asking if they could sell me an identical replacement. A clerk there said that they can't because my "prescription expired," and it would be illegal for them to sell me a replacement unless I either presented an "unexpired" prescription or else had the optometrist who wrote the original prescription extend its expiration date.
The clerk claimed that the sale of prescription eyeglasses is regulated in the same way as the sale of prescription drugs. I can't find any law or regulation supporting this claim.
What, if any, legal or regulatory restrictions apply to the sale of eyeglasses to individuals without a "current prescription," or any third-party "prescription" at all?
E.g., if I want to buy a pair of eyeglasses with lenses ground to +1.25 | -1.00x180, does the seller face any adverse consequences for selling me those based only on my specification, and no evidence that any optometrist has "prescribed" that specification for my purchase?
