Lack of awareness about eye conditions and poor access to treatment are major hindrances to those with visual impairment. Sadly this can be the leading cause of loss of vision in many people. Let us work together to increase awareness about eye diseases and promote regular eye checkups. It is recommended to have a complete eye exam at age 40, based on the results of which your doctor can recommend how often you should have future eye exams. If you are 60 or older, have your eyes checked every year or two.
