Thanks for visiting my crowdfunding page!

We take our vision for granted, seeing colour for what it is, is something that most people don't give a second thought. Unfortunately, this isn't the case for my husband as he is colour blind. The aim of this crowdfunding page is to raise money to have a test to determine which type of colour blindness and to then purchase a pair of specialised glasses which will enable him to see things as we do.

"People with dichromatic colour vision have only two types of cones which are able to perceive colour i.e. they have a total absence of function of one cone type. Lack of ability to see colour is the easiest way to explain this condition but in actual fact it is a specific section of the light spectrum which can’t be perceived. For convenience we call these areas of the light spectrum ‘red’, ‘green’ or ‘blue’ . The sections of the light spectrum which the ‘red’ and ‘green’ cones perceive overlap and this is why red and green colour vision deficiencies are often known as red/green colour blindness and why people with red and green deficiencies see the world in a similar way.

People suffering from protanopia are unable to perceive any ‘red’ light, those with deuteranopia are unable to perceive ‘green’ light.

People with both red and green deficiencies live in a world of murky greens where blues and yellows stand out. Browns, oranges, shades of red and green are easily confused. Both types will confuse some blues with some purples and both types will struggle to identify pale shades of most colours.

However, there are some specific differences between the 2 red/green deficiencies.

Protanopia

Protanopes are more likely to confuse:-

1. Black with many shades of red

2. Dark brown with dark green, dark orange and dark red

2. Some blues with some reds, purples and dark pinks

3. Mid-greens with some oranges

Deuteranopes

Deuteranopes are more likely to confuse:-

1. Mid-reds with mid-greens

2. Blue-greens with grey and mid-pinks

3. Bright greens with yellows

4. Pale pinks with light grey

5. Mid-reds with mid-brown

6. Light blues with lilac"
