An optician is a technician who makes and checks lenses,
glasses, and
contact lenses. They take a prescription from an
Ophthalmologist or
optometrist and make the glasses or help choose the correct type of
contact lens in terms of fit and how hard/soft.
Note that they cannot prescribe lenses or anything, not even eye drops. All they do is take your prescription and grind out the lens. Simple job, requires less training than an optometrist or Ophthalmologist.
