Optician is a general term that covers both optometrists and dispensing opticians. When you visit an optician you may have your sight tested by an optometrist or an ophthalmic medical practitioner. They are trained to recognize abnormalities and diseases in the eye, such as cataract and glaucoma.
Your eyesight is precious, which is why having regular eye tests is so important. The NHS provides free eye tests and help towards the cost of glasses for qualifying customers. Regular eye tests are important, which is why we recommend you have an eye test at least every two years, whether you feel you need spectacles or not. You may be entitled to a National Health Service (NHS) eye test which is free. You are entitled to a free eye examination, paid for by the NHS if: an ophthalmologist (eye doctor) has advised you that you're at risk of glaucoma, you are a war pensioner and you need the sight test because of a disability for which you get a war pension and you are 40 or over, and your mother, father, brother, sister, son or daughter has been diagnosed with glaucoma. It is important to have an eye examination at least once every 2 years as this is a vital health check for your eyes.
