I recently purchased these online, but I mistakenly bought them without realizing they were reading glasses. Unfortunately, I can't return them, and I won't have any use for them, so I'm putting them up for sale. The reading glasses come with a case. I only opened the plastic and tried them on once to see how they felt. Please note that I am only selling one set. The color of the reading glasses is black. 【Product Description】 Latest model of PINT GLASS progressive multifocal intelligence smart zoom function reading glasses.

Also, they do not have astigmatism or myopia correction functions, so they may not be suitable depending on your eye condition.
