Introduction
Colour blindness, or color vision deficiency, is a condition where individuals have difficulty distinguishing between certain colors, most commonly red and green. While usually inherited, it can also develop later in life due to eye diseases or certain medications. At Shreya Eye Centre, Dr. Rakesh Gupta offers expert evaluation and management for patients with color vision problems.
Common Causes of Colour Blindness
Genetic Factors: The most common cause, often passed from mother to son.
Age-Related Changes: The lens of the eye may yellow over time, affecting color perception.
Eye Diseases: Conditions like glaucoma, macular degeneration, and diabetic retinopathy.
Injuries or Trauma: Damage to the retina or optic nerve can alter color perception.
Medications: Some drugs used to treat heart disease, high blood pressure, or infections may affect color vision.
Chemical Exposure: Certain industrial chemicals may cause color vision changes with prolonged exposure.
Symptoms of Colour Blindness
- 1. Difficulty distinguishing between shades of red and green (most common)
- 2. Confusing blues with purples or yellow with light greens
- 3. Trouble identifying colors in poor lighting
- 4. Reading colored charts or graphs inaccurately
- 5. In severe cases, seeing everything in shades of gray (very rare)
Diagnosis and Management
Color Vision Testing: Simple, non-invasive tests like the Ishihara test can identify color vision deficiencies.
Genetic Counseling: For families with a history of inherited color blindness.
Specialized Lenses and Glasses: Tinted lenses or color filters may improve color perception in some cases.
Adaptation Techniques: Learning to rely on patterns, labels, or brightness instead of color cues.
Support for Students & Professionals: Guidance in choosing suitable career paths and coping strategies.
If you or your child struggles with identifying colors, especially at school or work, it’s important to consult an eye specialist. Color blindness can impact learning and daily life, but early diagnosis can help manage challenges effectively.
