Optometrists examine eyes, test vision, prescribe glasses and contact lenses, and detect eye diseases such as glaucoma and cataracts, as well as signs of wider health problems. You need an optometry degree, typically three to five years, or a four-year Doctor of Optometry after university study in the United States and Canada. Most work in community eye care practices, and some work in hospitals.
Most optometrists work in community practices, from independent shops to large retail chains, often in town centres or shopping areas. Others work in hospital eye departments alongside ophthalmologists, in specialist contact lens or low-vision clinics, universities, research or industry. Some visit people at home who cannot travel. Hours are usually regular but can include evenings, Saturdays and public holidays in retail settings. The work is indoors, detailed and involves seeing many patients a day.
Essential skills listed for this occupation in ESCO, the European Commission's multilingual classification of skills and occupations.
Essential knowledge: preventive medicine · eye protection regulations · quality standards of ophthalmic equipment · optical glass characteristics · refraction of the eye · optical instruments
You need an optometry degree approved by your national regulator or professional body. In the UK, you complete a three- or four-year degree and a period of supervised practice. In Australia, India and many Asian countries, optometry degrees usually take four to five years. In the United States and Canada, you complete university study, usually a bachelor's degree, then a four-year Doctor of Optometry programme and national exams. In some European countries, the profession is organised differently, with training through vocational colleges or combined with dispensing glasses. After qualifying, you register or get a licence before you can practise.

Optometry is a regulated profession in most countries, although the rules vary more than for many health careers. Usually you must register with a national or state regulator after an approved degree and supervised practice or exams. The scope of practice differs a lot: in some countries optometrists can prescribe medicines and manage eye diseases, while in others they mainly test sight and fit glasses. In a few countries optometry is not recognised as a separate profession. Check the local rules before you choose a programme.

Demand for eye care is growing as populations age and more people develop conditions such as diabetes, glaucoma and short-sightedness, which is becoming more common among children in many countries. Many health systems are moving eye care from hospitals into the community, giving optometrists wider clinical roles. Online sales of glasses and contact lenses and automated sight tests may put pressure on some retail work, so specialist clinical skills are likely to become more valuable.
An optometrist examines eyes, tests vision, prescribes glasses and contact lenses and detects eye disease. A dispensing optician fits and supplies glasses and lenses from a prescription. An ophthalmologist is a medical doctor who specialises in eye disease and eye surgery. In the UK, optometrists are often informally called opticians, which can cause confusion.
In the UK it usually takes around four years, including a degree and supervised practice. In Australia, India and many other countries, optometry degrees typically last four to five years. In the United States and Canada, you usually complete a bachelor's degree and then a four-year Doctor of Optometry, so around eight years in total.
In some countries, yes. Optometrists in the United States, Canada, Australia, New Zealand and the UK can prescribe certain eye medicines, sometimes after extra training or as part of their degree. In other countries, their role is limited to testing sight, fitting lenses and referring patients with eye disease. The rules change over time, so check the regulator in your country.
It can be. Optometry offers regular hours, direct patient contact and a clear clinical role, and demand for eye care is growing. However, much of the work is in busy retail settings with sales targets, and your scope of practice depends heavily on the country. Consider whether you enjoy careful, repeated testing as well as clinical problem solving.
