Ophthalmic Laboratory Technicians
Ophthalmic laboratory technicians may specialize in one activity or perform several functions in the laboratory. There are two major aspects of ophthalmic laboratory work: lens grinding and lens finishing. The work of the lens grinder begins with a standard-size lens blank, which is usually mass produced by an optics company and sold to the ophthalmic laboratory. Following the specifications included in a patient's prescription, lens grinders pick the proper lens blank for the job, measure and mark the lens for grinding and polishing according to the prescription, and set up and operate the machines that grind and polish the lens. They measure the lens with precision instruments, such as lensometers and objective lens analyzers, to make sure that they meet prescribed specifications.
