To fit contact lenses, dispensing opticians measure eye shape and size, select the type of contact lens material, and prepare work orders specifying the prescription and lens size. Fitting contact lenses requires considerable skill, care, and patience. Dispensing opticians observe customers' eyes, corneas, lids, and contact lenses with special instruments and microscopes. During several visits, opticians show customers how to insert, remove, and care for their contacts, and ensure the fit is correct. They may work in medical offices or small stores where customers are served one at a time, or in large stores where several dispensing opticians serve a number of customers at once.
Opticians spend a lot of time on their feet.
If they prepare lenses, they need to take precautions against the hazards associated with glass cutting, chemicals, and machinery. Most dispensing opticians work a 40-hour week, although some work longer hours. Those in retail stores may work evenings and weekends. Some work part-time. About 50 percent worked for ophthalmologists or optometrists who sell glasses directly to patients.
