Color Vision Deficiencies

Color vision deficiency is a term that is used to describe one of a number of hereditary or acquired color vision problems. The inherited form is the most common deficiency. It affects both eyes and does not worsen over time. This type of color vision deficiency occurs more in males than in females.

Color vision deficiencies may be partial (affecting only some colors) or complete (affecting all colors). Complete color deficiency, also known as color blindness, is rare. More often, individuals have a deficiency with one of the three photosensitive pigments in the eye: red, green or blue. Those people with normal color vision are referred to as trichromats. People with a deficiency in one of the pigments are called anomalous trichromats (the most common type of color vision deficiency). A dichromat has a complete absence of one cone pigment.

The most common signs of color vision deficiency are difficulty distinguishing between reds and greens or difficulty distinguishing between blues and greens. There is no cure for color vision deficiency. However, those with mild color vision deficiencies can be taught to associate colors with certain objects. In some cases, color vision deficiency can affect child development and career choice, which is why early detection is critical.

What Our Clients Say About Us

  • "I have been to Visio Eyecare for the past three years and I am very satisfied with this place. Number one perk, they are open on Sunday and getting an appointment is extremely easy! The eye doctor is very nice and helpful; she really listen to what you want and if you say you do not want to spend a dime over what is necessary, she listens and advises you on glasses under your budget; my glasses have always been ready quickly; I will recommend this place to anyone!"

  • "I had a wonderful experience today. Called and they had me come in immediately for an appointment. Everyone was extremely nice and Dr Au helped me choose my new glasses.
    I will be going back yearly."
    Michael B.
  • "Dr. Au is GREAT! I can't say anything better about her. She makes you comfortable, explains your insurance claims and gets you the best deals within your budget."
    Lauren B.
  • "I never thought I would feel compelled to write a yelp review for an eye doctor but Dr. Au and her receptionist are so awesome that I must! I just moved to the area and had run out of contacts so I just googled the closest eye dr. She has given me multiple lens samples so I can find what best works for me before ordering. I feel so cared for in her office and am so happy I found her."
    Meredith K.
  • "Great service at a very fair price. Skip that chainstore and that place with the fancy waiting room and go here."
    Paul K.
  • "I've worn glasses for about 15 years and this is the most personable interaction I've ever had at an eye center. Dr. Au and the receptionist were sooo sweet and considerate. I came here unintentionally as I was desperate for an appointment and they had an opening the same day. I'm so glad I found this place! Not to mention I was in and out in 30 minutes and they have great COVID precautions!"
    Jaicha V.
  • "Dr. Au and her receptionist are the nicest! They make everything super fast and easy and explain everything very clearly. She referred me to Wills Eye Hospital for additional testing and they were very impressed that she had picked up on a rare issue that I have with my eyes. I highly recommend Dr. Au!"
    Sarah C.
