Prescription glasses, silver. The part that rests on the ears causes some pain. The lenses are -3.25 for the right eye and -3.5 for the left eye. The seller's unaided vision is 0.05 in one eye and 0.1 with both eyes. Ideally, these should be made based on an ophthalmologist's prescription or by an optician, but I am listing them in the hopes that someone can use them for everyday use, or as a backup in emergencies or disasters. Thank you very much.
