Opticians assist customers who require vision tests, prescriptions, repairs, and, in some cases, minor eye surgery; essentially, they helps customers determine which prescription they require and assist with any other questions or needs that they may have. Opticians use a piece of equipment called an phoropter to measure the depth of vision that each customer has, and then they are able to determine exactly which prescription the customer needs. Other equipment is also used, including a tonometer, which injects a small amount of air pressure into the eyeball to test for glaucoma. All opticians should be familiar with this equipment, and some may also be able to operate laser surgery machines for outpatient correction procedures.
