What’s the difference between optician, optometrist, and ophthalmologist?
Ophthalmologists are medical doctors who diagnose and treat all eye diseases, perform eye surgery and prescribe medicine to correct vision problems. If you have been referred to an ophthalmologist by your family doctor, optometrist or other health care practitioner, you can locate one using this tool – available at the COS website
