If you're getting OLD-er & need reading glasses because your ophthalmologist broke your heart by telling you your prescription became stronger (heehee ok my heart has healed); then dollar stores are great!!
They had hundreds of glasses to choose from for only dollar $1 each! I picked up nine (9) different styles/colors. They do have more masculine styles available too. So much cheaper than other non-dollar stores you can buy at. You can definitely have backups in different rooms at home, work, car, purses & etc.
They are good about current expiration dates on items. I personally sterilized/cleaned everything. I have seen a spill or two here but for the most part it looks relatively organized & clean-ish w/ wide variety. I've been here twice.
PS: I did noticed the attempted escaping of balloons on the ceiling & alas they are doomed. RIP balloons.
