Optometrists examine people’s eyes to diagnose vision problems, eye diseases, and other conditions. Using various instruments and their trained eyes, optometrists test for depth and colour perception, as well as the patient’s ability to focus and coordinate the eyes.
When necessary, optometrists prescribe corrective lenses and rehabilitative treatment. For example, an optometrist may diagnose someone with myopia, which means the person sees close objects clearly but can’t see distant objects with the same clarity. The optometrist will then prescribe lenses that adjust the way light rays enter the eye so the patient can see near and far objects with equal clarity.
Optometrists may also provide vision therapy for those with vision problems or those who have recently had eye surgery. If, while examining a patient, they find evidence of disease, such as diabetes or high blood pressure, they refer the patient to another health care practitioner.
In addition, optometrists in most provinces and territories can remove foreign bodies, such as splinters, from the eye, and apply eye drops and ointments. Optometrists must follow any regulations set by their province or territory when performing these types of tasks.
Most optometrists work in general practice, but some specialize in eye care for children, the elderly, or partially sighted people. Others may develop ways to reduce on-the-job eyestrain for workers, specialize in sports vision, teach, research, or consult.
Optometrists should not be confused with ophthalmologists or opticians. Ophthalmologists are medical doctors who specialize in all aspects of eye care. In addition to examining eyes and prescribing eyewear, ophthalmologists can perform eye surgery as well as diagnose and treat eye diseases and injuries. Opticians fit eyewear according to prescriptions written by ophthalmologists or optometrists.
