What is a sight test and how does it differ from an eye health exam?
Simply put, a sight test checks a person's vision only, and an eye health exam checks for any disease and the vision as well.
An eye health screening is provided by an optometrist, by physicians in the course of general practice, and by ophthalmologists - medical doctors specializing in diseases of the eye.
The purpose of an eye health examination is to observe eye structures and cell tissue for any early signs of eye disease and the necessary correction for vision.

What is the difference between an optician, ophthalmologist and an optometrist?
Opticians are trained and qualified lens, frame and contact lens specialists.
Optometrists provide vision testing services and are also trained to perform eye health examinations. Some of the other services optometrists provide are orthoptic training services, visual field testing, and glaucoma testing.
An ophthalmologist is a medical doctor trained in detecting and treating diseases of the eye, and in performing eye surgeries.

If I’ve never had an eye test before but I think I need glasses, can I go to an optician?
In short, no. You should have a complete eye examination every two years. Opticians can modify your prescription eyeglasses, sunglasses, contacts, but the safer bet is to consult an optometrist. An optician will be more than happy to refer one to you. A lot of opticians have an optometrist on premises.
