People who are color blind see colors differently than other people. Color blindness usually refers to a color deficiency where it’s difficult to distinguish between different colors. True color blindness, when one can only see black and white, as the term connotes, is extremely rare. The most common type of color blindness in the inability to see the difference between shades of red or green. For example, people with red/green color deficiency will have a difficult time distinguishing between blue and purple because they can’t see the red element which is part of the purple hue.
Color blindness is usually an inherited condition and is much more common in males than it is in females. Approximately five to 8% of men have color blindness while in women it’s only around half to 1%. We have certain light sensitive cells at the back of our eyes known as photoreceptors. There are two types of photoreceptors; rods and cones. The rods are responsible for helping us see in the dark while the cones are responsible for color vision and seeing in daylight. If someone is color blind there are certain deficiencies with the function of the cones.
If you think you have color blindness, please Book an Appointment to see Dr. Zurcher who will be happy to check your ability to perceive colors. People who are color blind tend to adjust and don’t have issues with daily tasks and activities.
If you were born being able to see the full range of colors and then either over time or suddenly you notice difficulty in distinguishing colors, please Book an Appointment with Dr. Zurcher as this could be a sign of an underlying condition such as cataract.
You may notice on your own that you’re getting confused between colors or the people around you may tell you that the color which you think you are seeing is actually wrong. If this sounds familiar to your experience then there’s a chance that you may have color blindness.
Color blindness does not usually manifest as only being able to see in black and white. There are different types of color blindness depending on which colors the person has difficulty with and also the amount of colors that are deficient. Usually people with this condition can’t distinguish between certain colors such as red and green. In addition, colors appear to be washed out and are hard to differentiate.
Color blindness can also develop over time or suddenly, as opposed to being a condition from birth. Acquired color blindness could be caused due to:
There’s no way to prevent or treat color blindness from birth, but the good news is that it’s almost always considered to be a mild condition and it should not affect your day to day functionality. There are special glasses or contact lenses that can help with color blindness. If a person was not born with color blindness but acquired it over time then your eye doctor will treat the underlying cause.
Color blindness occurs when a person doesn’t see colors like most people do. It doesn’t usually affect daily functionality as most people with this condition adapt. If you think you have color blindness, you can Book an Appointment with Dr. Zurcher.
