Not Everyone Sees the Same Colors
Color vision deficiency is a condition where your eyes struggle to distinguish between certain shades of colors. People can experience red-green deficiencies, blue-yellow deficiencies, and even complete color deficiency. Total Vision Huntington Beach is here to help you understand why this happens and what you can do to manage the effects.
How Your Eyes See Colors
Light enters your eye and is focused onto a sensitive layer of tissue at the back called the retina. This tissue contains specialized cells known as cones. These cones react to different wavelengths of incoming light, and they help you detect red, green, and blue light waves.
When your cone cells lack certain pigments, they send incomplete color information to your brain. If you have less of a given pigment than normal, you may simply struggle to distinguish certain colors. If you lack that pigment completely, you may be unable to distinguish some colors at all.
Common Types of Color Blindness
People experience color vision differences in a few specific ways.
Red and Green Deficiencies
In this form of color deficiency, people struggle to tell red and green apart, and it’s much more common in men.
There are several forms of red-green deficiency, each of which has a slightly different effect on your ability to see color. However, one common form of this condition is called protan deficiency, and it makes red shades look more green to your eyes.
Red-green deficiency often doesn’t substantially affect daily tasks. In cases where color distinctions are important, such as when navigating traffic lights, many people learn to memorize the relative positions of objects rather than distinguishing them by color.
Blue and Yellow Deficiencies
This type happens when your eyes struggle to identify blue. Blues may look green, and you may also struggle to perceive yellows.
This condition is less frequent than red and green deficiencies, and it affects men and women at equal rates.
Complete Color Deficiencies
You see everything in shades of gray with this condition. This very rare condition is known as achromatopsia.
It often comes with extreme light sensitivity. You might need to wear dark glasses even on cloudy days to stay comfortable.
Risk Factors & Health Conditions
Genetics & Family History
Color vision deficiency is usually passed down from mother to son. About 1 in 10 men has some form of color deficiency.
This inherited trait usually remains stable throughout your entire life. Your color perception rarely worsens if the condition stems from your genetics.
Health Conditions and Age
Certain health issues like glaucoma can sometimes cause color vision deficiencies as they progress. Some medications can also affect how a person sees color.
As we age, we also tend to see colors less vibrantly.
Diagnosis & Treatment Options
Finding the right support starts with a comprehensive eye exam. As your eye doctor in Huntington Beach, we can identify color vision deficiency as part of a regular eye exam. The most common test involves showing you a series of images filled with colored dots and asking you to read numbers from the image.
While there isn’t a cure for color deficiency, some tinted glasses and contact lenses are designed to make colors easier to distinguish. You can also develop habits at home, like labeling colorful items in your kitchen and workplace, to help reduce frustration.
If you’re struggling with color deficiency, book an eye exam with our team at Total Vision Huntington Beach and let us help you find a practical solution.
