Do they accept donations of used eyeglasses?

Yes

I think it depends on location and whether a local group or agency sponsors the collection. I don't believe Costco corporate does so.

Artisans Bank on Rt 40 does.

Not when I asked a few years back.

I have not seen them taking .. appreciate your kind ness though

Very good question that is best addressed to the store itself rather than customers on a Google Maps user forum.
