Visiting the optician at least once every 2 years is vital as your vision can change significantly in between check-ups. If you’re a contact lens wearer, it’s a good idea to have an eye test yearly so you’re wearing lenses with the most accurate prescription and avoid unnecessary strain or discomfort.
Eye tests can also detect symptoms of a range of health conditions, not limited to your eyes. When you visit an optician for an eye test, the optometrist or ophthalmologist that carries out the examination has been trained to recognise any problems such as cataracts or glaucoma. They’ll also check for symptoms of diabetic retinopathy, an effect of developing diabetes.
