either online or local, sell contact lenses without prescriptions or even ship contact lenses that are the wrong prescription or brand that the doctor originally prescribed. The incorrect contact lenses will not properly fit the eye and can cause significant damage to the eye’s function, which could lead to irreversible loss of vision.
Do not panic if you “lose” a lens in your eyes. This usually happens if you rub your eyes. It is impossible for the contact lens to be lost behind your eyes due to a membrane called the conjunctiva that covers the entire eye. Try putting a few drops of saline or artificial tears into your eyes which will in turn moisten the lens and your eyes, then look off to the side to see if you locate the lens.
