This online visual acuity test is not a medical evaluation and does not replace a visit to a eye care professional. It is not designed to be used as a diagnosis for illness or other conditions, for treatment, or for the mitigation or prevention of illness. This test simply aims to give you a general idea about your visual capacity. We recommend that you follow-up this test with a full vision evaluation by a vision care specialist. Only eye care professionals can make decisions on medical treatment, diagnosis or prescription.
