Relationships with occupations

Essential knowledge

Optical instruments is an essential knowledge of the following occupations:

Optoelectronic engineer: Optoelectronic engineers design and develop optoelectronic systems and devices, such as UV sensors, photodiodes, and LEDs. Optoelectronic engineering combines optical engineering with electronic engineering in the design of these systems and devices. They conduct research, perform analysis, test the devices, and supervise the research.
Optician: Opticians help to improve and correct an individual’s vision according to prescriptions provided by a specialised doctor in ophthalmology or an optometrist. They fit spectacle lenses and frames, contact lenses, and other devices to the specifications of both the individual and the prescription. Opticians do not test patients vision nor write prescriptions for visual correction. Their scope of practice varies according to national regulations.
Optomechanical engineer: Optomechanical engineers design and develop optomechanical systems, devices, and components, such as optical mirrors and optical mounts. Optomechanical engineering combines optical engineering with mechanical engineering in the design of these systems and devices. They conduct research, perform analysis, test the devices, and supervise the research.
Optometrist: Optometrists examine and test eyes to identify abnormalities, visual problems, or disease. They prescribe and fit lenses such as spectacles and contacts, and offer advice on visual problems. They may also refer patients to a medical practitioner. Their scope of practice and title varies according to national regulations.

Optional knowledge

Optical instruments is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Optical technician: Optical technicians assemble, repair and design various parts of eyewear such as lenses, frames, patterns and eyewear. They cut, inspect, mount and polish all parts using various machinery and hand tools. Optical technicians shape, grind and coat lenses for prescription eyewear. They fit completed lenses into eyeglass frames. Optical technicians ensure that lenses conform to the dispensing optician’s, specialised doctor in ophtalmology’s or optometrist’s prescriptions. They may also work with other associated optical instrumentation and its maintenance.
Optical engineer: Optical engineers design and develop different industrial applications with optics. They have knowledge of light, light transmission principles, and optics in order to design engineering specs of equipment such as microscopes, lenses, telescopes, and other optical devices.
