Note: This page is intended solely
for those suffering from color blindness.

While we are mainly concerned with humor here at Dribbleglass.com, we also happen to care deeply about those afflicted with color blindness.

If you are reading this, you are one of the unfortunate souls who sees the world only in black, white and shades of gray. This is tragic.

That is why this page is devoted to you. We want to do our part to disseminate information about your condition. It's a small gesture, but hopefully one which will give you hope as you go about the business of living in a colorless world.

The Basics

As you probably know, color blindness may be hereditary, or can be caused by disease of the optic nerve or retina.

Inherited color blindness is most common. This type is found in about 8% of males and 0.4% of females. These color problems are linked to the X chromosome and are almost always passed from a mother to her son.

Photoreceptors called cones allow most people to appreciate color. These are concentrated in the very center of the retina and contain three photosensitive pigments: red, green and blue. As a person who is color challenged, you have a deficiency or absence in one or more of these pigments.

Resources for the Color Challenged

The following are links to information about color blindness. Again, we understand there is no cure for your ailment, but knowledge is power.

We hope this information will prove useful to you, and again, we admire you for your courage in grappling with this tragic medical mystery.
