Optical Technician

Job overview
Optical technicians prepare lenses according to prescriptions from optometrists and ophthalmologists.

What do people do in this job?
These prescriptions contain details of the size, shape and strength of the lens, location of optical centre, position of bifocal segments (if required) and the type of frame.

Optical technicians may only have to fit lenses according to clients' needs, since the majority of lenses and frames are imported and a stock of prepared articles is held by optical laboratories.

In the manufacture of lenses, optical technicians must first examine the lenses for defects in the glass as well as the curve, thickness and size of the glass.

The lenses are cut with a machine to produce the prescribed curve, and then buffed and polished.

The lenses must be shaped to fit the desired frame according to prescription.

Optical technicians also repair damaged lenses and frames and prepare contact lenses.

What kinds of people are suitable for this career?
Accuracy, good eye-hand co-ordination and good vision are essential qualities.

Optical technicians must have a mechanical aptitude and enjoy doing fine handwork.

What qualifications are needed? 
There are no set qualifications, apart from a good all-round school education.
