People between the ages of 0-19 and 65 and over are covered by OHIP for their appointments. Contact lens assessments, vision therapy and some diagnostic tests are not covered by OHIP. Those who have certain eye and medical conditions are covered between the age of 20 and 64, including diabetes, cataracts, glaucoma and macular degeneration, for example. Your optometrist will be able to make the decision if you are eligible for OHIP coverage when they do a full eye examination. Those who are covered under OHIP are eligible for a full eye exam once a year, as well as partial appointments as needed within the year.
