An optician is an eye care professional who helps you choose, fit and adjust glasses and contact lenses. An optician also carries out an eye test and can refer you to an ophthalmologist if you have any symptoms or abnormalities.

What is an optician?

An optician is a qualified eye care professional who specialises in testing your eyesight and advising on, prescribing and fitting spectacles and contact lenses. In the Netherlands, opticians undertake vocational training (MBO) or higher vocational education (HBO), during which they learn how the eye works, how to measure refractive errors and how to determine the correct correction.

The optician carries out an eye test, also known as a refraction test, to determine the correct prescription you need. During this test, the optician assesses your visual acuity and checks whether you are short-sighted, long-sighted or have astigmatism. An optician can also screen your eyes for signs that may indicate an eye condition, and refer you to an optometrist or ophthalmologist for further examination.

As well as fitting glasses and contact lenses, an optician advises you on the right type of glasses or contact lenses for your situation, and on the maintenance and care of your lenses. With contact lenses, the optician checks that the lens fits your eye properly and that your cornea remains healthy.

Good to know

What does an optician do?

An optician measures your eyes, determines the correct prescription for spectacles or contact lenses, and fits the spectacles or lenses. They also provide instructions on how to insert and remove contact lenses and on how to care for them properly. Many opticians offer a follow-up appointment to check that the lenses are still fitting properly and that your eyes are healthy.

The difference between an optician and an optometrist

An optician has completed a vocational or higher vocational qualification and is authorised to carry out eye tests and fit spectacles and contact lenses. An optometrist has completed a higher vocational or university degree and is authorised to carry out more comprehensive eye examinations, for example using equipment to assess eye pressure or the retina. In practice, opticians and optometrists often work together in the same shop or practice.

When should you visit an optician?

You should visit an optician if you notice your vision is becoming less clear, if you get headaches when working at a computer screen, or if you need new glasses or contact lenses. You can also visit an optician for a lens check-up or if you have any questions about comfort or aftercare. If you experience symptoms such as pain, redness, flashes of light or sudden loss of vision, the optician will refer you to an ophthalmologist.

Opticians and contact lenses

When it comes to contact lenses, the optician not only measures your prescription but also the curvature of your cornea and the size of your pupil. This is necessary to find a lens that fits well and is comfortable to wear. The optician will teach you how to safely insert and remove the lenses and which lens solution is suitable for your type of lens. At SMEYEL , you’ll find a wide range of contact lenses and lens solutions which you can order following advice from your optician.

Frequently asked questions

For an eye test, a new pair of glasses or contact lenses, you should visit an optician or optometrist. If you have symptoms such as pain, sudden loss of vision, flashes of light or persistent redness, an ophthalmologist is the right person to see. The optician may refer you if they notice anything that requires further investigation.

That depends on your age and the condition of your eyes. Adults with no symptoms can have an eye test every two to three years. If you wear contact lenses, an annual check-up is standard practice to ensure the lenses still fit properly and your eyes are healthy. If you notice any changes in your vision, you should visit sooner.

An optician or optometrist may spot signs that could indicate an eye condition, for example during a screening of your retina or eye pressure. For a diagnosis and treatment, the optician will refer you to an ophthalmologist. The optician does not make a diagnosis or prescribe medication themselves.

You can order contact lenses online if you have a recent eye test and fitting from an optician or optometrist. These details are on your contact lens prescription or order voucher. Only order lenses that match those specifications, and have your eyes checked regularly to ensure they remain healthy.
