Colour blindness, medically referred to as colour vision deficiency (CVD), is a visual impairment that affects the ability to distinguish between specific colours, most commonly between red and green, but also blue and yellow in some cases.
In rare instances, individuals may experience complete colour blindness (achromatopsia), where no colour is perceived at all. The condition is most often inherited genetically, though it can also be acquired as a result of ocular disease, neurological disorders, medication side effects, or age-related changes in the eye.
At Tonic Eye Care, we provide comprehensive eye exams that include assessments for colour blindness in Toronto as part of our diagnostic services. These assessments are designed to identify the type and extent of colour vision deficiency accurately and to support patients in understanding how it may impact their functional vision and quality of life.
Our optometrists use clinically validated tools and evidence-based methods to assess colour discrimination. If you or your child are experiencing difficulty identifying colours or if you have concerns about colour vision’s role in education, career development, or daily activities, our team is equipped to provide a thorough evaluation and professional guidance.
