When the finished glasses are returned from the laboratory, RSLDs use optical tools and gauges to make sure that the glasses match the work order. Opticians adjust glasses to fit their customers comfortably. Some Dispensing Opticians also grind and polish the lenses and mount them into frames. RCLDs fit contact lenses by measuring the shape and size of the eye. They select the type of contact lens material and train the wearer to insert and remove the lenses and clean and maintain them properly.
Opticians use various instruments to help select and fit contact lenses for their customers.
They work in retail optical stores and in eye clinics. They may work in 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 deal with customers most of the time and may spend a lot of time on their feet. If they also prepare lenses, they must take precautions against the hazards associated with glass grinding, chemicals and machinery. RSLDs may join the California Association of Dispensing Opticians.
