Q: Do colourblind people only see grayscale?

A: As the wordings color blindness and colorblind have a liberal usage, this is not true. Most of the people called colorblind suffer from red-green color blindness and some of blue-yellow color blindness. Only very few are affected by achromatopsia and just some of those are completely colorblind. But if so there is a smooth transition to blindness and there is no hard line between really being colorblind, highly sensitiveness on bright light and blindness. And the conclusion is, colorblind people can see colors but just can’t distinguish all of them. 99% of all colorblind people are not really color blind but color deficient; the term color blindness is misleading.

Q: If men are colourblind then does this mean they get it passed on from their fathers?

A: The most common red-green color blindness is a sex-linked trait. Therefore it is encoded on the X-chromosome which is passed on from a mother to her son and not the father.

Q: So do colour blind people see the world like dogs?

A: No, as in reality dogs are not really colour blind and have the ability to perceive colours. They just perceive the colour range differently from say a human being with normal vision. So dogs really have a form of colour vision deficiency. Which means they are colourblind….What was you question again?!

Q: Is colour blindness realy an issue?

A: Researches have shown that colorblind people definitely feel handicapped in their everyday life and almost nobody recognizes this.. There are many situations and stories to tell where color blindness is a little or even a big burden.

Q: Is there a medicine for that?

A: There is no cure or treatment available currently for colour blindness. People can get assistance through specialized software and the use of specific glasses, but that doesn’t mean they get their normal vision back.
