Other forms: opticians
The person who makes your eye glasses is an optician. They work in the back room of the glasses shop, or at a factory, fabricating the lenses and attaching them to the frames.
While an optician can determine whether you are nearsighted or farsighted, if you have a medical eye problem, you probably want to visit an optometrist or an ophthalmologist. Both of these are eye doctors, but the latter has completed full medical training and has chosen eye health as a specialty.
