Color Blindness

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. Wernick 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. Wernick as this could be a sign of an underlying condition such as cataract.

Symptoms

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:

  • An optic nerve disease - the optic nerve connects the back of the eye to the brain
  • A stroke inside the eye which occurs due to blocked arteries of the eye
  • Eye diseases such as cataract or macular degeneration
  • Some medications
  • Various toxic chemicals
Symptoms

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.

Common Questions

There are many different types of color blindness, depending on which specific colors and the amount of colors cannot be perceived properly. The main categories are Deuteranomaly - reduced sensitivity to green light; this is the most common type, Protanomaly - reduced sensitivity to red light, and Tritanomaly - reduced sensitivity to blue light; this is very rare
If you think you have color blindness, make sure to Book an Appointment with Dr. Wernick who can diagnose the condition. The eye doctor will perform a color perception test, known as the Ishihara test. You will be shown a page that has different colorful dots on it and camouflaged in the colors will be a colorful number or shape that you will be asked to identify. Someone who is not color blind will have an easier time identifying the number or shape on the page, whereas a person with color blindness will have a much harder time finding the number or shape amongst the other colors on the page.
Both yes and no. Typically, males with genetic color blindness, which is estimated to be 8% of all males, cannot have color blindness in only one eye. It is possible, however, that a genetic or acquired disorder of the optic nerve and/or macula can decrease the color vision in one eye.

Testimonials


At Amplify with Dr Wernick I was seeking help for seemingly intractable, probably age-related dryness. I've seen other doctors about it, and that has been helpful, but what he explained to me about it and the careful way he answered all my questions gave me so much more of a clear understanding of what is going on (and is not) that I am more able to implement all his and others' recommendations than I was before. And he gave me additional resources for further follow-up. I am most grateful.

Wow! This is a great Eye Care medical facility. I was thoroughly examined by Dr. Pinkhasov for over 2 hours. She made sure to check my eyes for pretty much everything and patiently explained proper care for my eyes. They definitely know how to provide great care and treat their patients right. Now I know why they have such a great reputation and been around for so long.

Dr. Kavner is a gifted diagnostician and orthoptic therapist. He treated me several decades ago for a condition similar to dyslexia. I was having migraines five times per week. I worked with him for about a year and I experienced tremendous improvement (down to 3-4 per year) that has lasted.

Dr. Kavner recommended two types of eye therapy for my daughter. One of them using bio-feedback. In just three sessions she is seeing considerably better. She shouted this morning: Ooh my God! I could not see these letters with my glasses on, and now I can see them without my glasses. If you are willing and able to invest in improving your vision, this is a good place to go to!

I have always found Dr Kavner's work, expertise and wisdom of the highest caliber. As one of the fathers of OT, occupational othomology, his depth and breadth of knowledge about the eyes' health and wellbeing of the patient is exemplary. Cannot say enough good things about him.
