From bright orange sunsets to brilliant blue skies, the world is bursting with a rainbow of colors to be seen. Unfortunately, not everyone gets to enjoy the variety of hues that surround us \u2014 something that is so often taken for granted!<\/span><\/p>\n

Around 300 million people suffer from color blindness. This means the color spectrum they see is more limited when compared to others. The most common form of the condition affects up to 8% of men and 1% of women.<\/span><\/p>\n

The severity of color vision deficiency varies from person to person. Some may only have trouble determining the brightness of a specific color, while others may not be able to tell one shade from another.<\/span><\/p>\n

What Causes Color Blindness?<\/span><\/h2>\n

Color blindness, or color vision deficiency, is caused by a malfunction or absence of some of the light-sensitive cells in the retina called the cones.\u00a0<\/span><\/p>\n

The retina has three cones \u2014 red, blue, and green \u2014 that each detect different wavelengths of light. When these cones don’t function properly, or when they\u2019re absent, color vision deficiency occurs. For example, someone with malfunctioning red or green light-sensing cones would suffer from red-green color blindness.<\/span><\/p>\n

The most common form of color blindness is red-green color deficiency. This type is often inherited. Other types, such as blue-yellow color blindness and complete color blindness, are much less common.\u00a0<\/span><\/p>\n
