Eyeglasses for the Color Blind

One in every 12 men and one in every 200 women has some degree of color blindness, also called color vision deficiency. The condition is not actual blindness, but rather an inability or decreased ability to see color and perceive differences in color. Color vision deficiency can be a partial or total deficiency, although total color blindness is not as common.

What Are the Types of Color Blindness?

There are two main types of color blindness:

  • Red-green – which is the most common type of color blindness, and is often inherited from the mother’s side on the X chromosome
  • Blue-yellow – which is rarer, and usually occurs from damage to the optic nerve or retina

In both of these types, the two colors are confused, as both are seen as grey-brown instead of the true colors. Color blindness can also result from disease, brain injury, and certain drug reactions.

What Are Color-Blind Glasses?

Color-blind glasses are eyeglasses with lenses that have special filters that may help a person with color blindness see specific colors more accurately.

They are made with certain materials to absorb and filter out some of the wavelengths between the green and red colors that confuse the brain. When wearing the glasses, some of the light coming through is blocked so that the remaining red and green light wavelengths don’t overlap as much. With less color overlap, the brain gets a clearer signal to help distinguish between the colors.

While there is no cure for color-blindness, color-blind glasses may give people who are color-blind an opportunity to see the world more accurately and experience a greater spectrum of colors while wearing the glasses. The positive effects of the glasses only last as long as they are being worn.

Color-blind glasses can improve the quality of life for people who experience color deficiency and provide a deeper vibrancy and greater array of color schemes.

Because each type of color blindness is unique, the effectiveness of color-blind glasses varies from patient to patient. Most of the color blind glasses available are designed to correct mild red-green color-blindness, leaving fewer options for those who experience severe red-green color blindness, or the blue-yellow type of the condition.

What Does it Mean to be Color Blind?

Are you color blind? Is there a treatment? Find out at our Citrus Heights, California , eye care center

Despite the name, being color blind has nothing to do with blindness. Rather, it’s a vision condition that compromises your ability to perceive all the colors of the rainbow. However, that doesn’t mean people who are color blind can only see black and white – they just see color differently from the majority of the world.

Millions of people around the globe are color blind, primarily due to genetics. What about you? If you’ve ever noticed that you have trouble differentiating certain colors (does your family always joke that your clothes don’t really match?), book an eye exam at EYEcenter Optometric. Our Citrus Heights, California , eye doctor will check your color vision with a specialized test.

What makes some people color blind?

You can’t understand how color blindness works without a basic understanding of how light and color vision work:

All objects reflect some wavelengths – while absorbing other wavelengths. When you see color, you’re seeing only the reflected light. For example, a vibrant sunflower blossom is only bright yellow because it reflects the medium-long wavelength of yellow and absorbs all the others.

Your eyes and your brain partner to see the different wavelengths of light. The cornea and the lens of your eye focus light onto the retina, which contains millions of light-sensitive photoreceptor cells. These cells are called rods and cones, after their respective shapes.

Rods and cones contain photopigment molecules that trigger electrical signals to be sent to the brain when they absorb light. Cones, which contain one of three different photopigments (red, green, and blue), respond stronger to bright light.

If your cones have a mutation that blocks their ability to respond to all the wavelengths of light, then the signals that communicate colors to your brain won’t be sent correctly = color blindness. The most common type of color blindness is red-green, which makes people see the world in duller, yellowish brown hues.

To find out if you’re color blind and to learn more about the different specialized glasses and lenses available for treating color blindness, visit our Folsom, California , eye care center. We’ll help you see the world in full color!
