Colour Blindness

What is Colour Blindness?


Also known as colour vision deficiency, colour blindness is when someone has difficulty or cannot distinguish between certain colours, usually with shades of red, green, yellow and more rarely, blue.

Colour blindness happens when the colour sensitive cells within the eye aren’t working properly or are missing.

Most cases are caused by an inherited genetic condition, usually from the mother’s side.

Who usually suffers from Colour Blindness?


Anyone can have colour vision deficiency, but it’s much more common in males.

It can also develop later in life as a result of health conditions like:

  • Diabetes

  • Glaucoma

  • Multiple sclerosis

Or as a side effect to certain medications.

At Optika Opticians, colour vision tests are not part of the usual eye exam, so make sure you let us know if you’d like one. If you have any concerns about your colour vision, it’s important to see your optometrist.
