Tenor and Alto Prescriptions
Hello all! We are thinking of buying these glasses as Christmas gifts, but wondering about the prescription lenses. Are they something that have to be ordered with the glasses when you first get them, or can you get the prescription lenses later? Some of our friends that we would like to purchase them for have prescription glasses, and we do not know their prescription and if we ask for it, might ruin the gift surprise. So we would like to purchase the Tenor and Alto glasses, but wanted to make sure they could add prescription lenses later if wanted.
