Innovations in Color Blindness

clipart 048

There have been a lot of videos going viral lately of color blind people “seeing color” for the first time using specialized glasses. The emotional reactions of amazement, shock and joy even lead some to break down into tears. The glasses provide these individuals a way to view the world in vibrant, living color, as everyone else around them is able to.

One in every 12 men and one in every 200 women have some degree of color blindness or color vision deficiency (CVD). The condition is not actual blindness, but an inability or a decreased ability to see color and perceive differences in color. CVD can be a partial or total deficiency, although total color blindness is not as common. There are two main types of color blindness:

  • red-green - which is most often inherited from the mother’s side on the x chromosome, and

  • blue-yellow - which is much more rare and usually occurs from damage to the nerve. CVD can sometimes be acquired through disease, brain injury or certain drugs or chemical reactions

The World of the Color Blind

Contrary to common misconceptions, a person who is color blind does not see only grey.  He still usually sees color to some extent, but often the colors appear dull or washed out and can be easily confused with other colors. People often have trouble identifying or naming certain colors or distinguishing colors, for example, red and green, as well as orange, yellow and brown may appear similar, particular in low light situations. In fact, while people with normal color vision typically see about one million unique shades of color, individuals with color deficiency are only able to perceive 5-10% of that.

People with color deficiency often do not know they are color blind until they are tested. They assume everyone else perceives colors the same way. Often individuals are tested when they are seeking out certain career paths in which it is essential to distinguish colors such as pilots, electricians or police officers among others.  

Innovations in Color Vision

Color blindness can impair certain aspects of daily life and limit certain activities or job options and therefore there are a number of companies out there working on technology to overcome these difficulties. While there is no cure for CVD, there are aids available that can sometimes assist with increased color perception.  

Eyeglasses/Sunglasses

There are a couple of brands of color enhancing glasses available that help some individuals with red-green colorblindness.

Both EnChroma and o2Amp Oxy-Iso Color Correction Glasses work for about 80% of people with red-green colorblindness - which means that not everyone will have the same experience as those that appear in the videos. The lenses enhance color perception by filtering out the light into different spectral components. EnChroma has two versions - indoor, designed for looking at computer screens and outdoor, sunglasses.  

Another solution is a custom designed ColorCorrection System in which contact lenses and glasses are customized for the individual and are available with or without a prescription. These lenses work by changing the wavelength of the colors as they enter the eye to enhance color discrimination and perception.

Apps for CVD

There are a growing number of apps available for smartphones and tablets that serve as color vision aids for those with CVD.  One example is the Colorblind Avenger which is a color identification program will allows the person to use their mobile device as a visual aid. The user takes a photo or selects an existing photo and when he touches an area on the image the app displays the color of the selected area.

Huevue is another app of colorblind tools that help people with CVD identify, match and coordinate colors. There are many other apps available out there to help aid those with CVD and educate others about living with the condition.

There are even video games and software design tools that are now created with colorblind modes to allow use by people with CVD. While none of these tools and aids are able to restore color vision permanently, they do allow those with the condition to live a more vibrant life.

Dear Northwood Vision patient,

COVID-19 has the potential to cause grave harm to many of the citizens in our population. According to Harvard epidemiologist Dr. Mark Lipsitch it is likely that at least between 40-70 % of the population will become infected with COVID-19. This virus is twice as contagious as the flu. About 80 percent will not have severe concerns, but based on the current data, 20% of the infected will become severe or critical, needing some form of hospital care to do well. Currently, about 30 % of those who become classified as severe based on WHO classification, will not survive. These are the unfortunate realities at the moment.

Meanwhile, at Northwood Vision, we want to do as much as possible to minimize this risk, to prevent mortality and long term side effects, while doing our best to provide the services our patients need. We are convinced you care about these same things. (Read more)

Here is what we are asking you to do to make a smaller exposure footprint:

  1. If you have any symptoms of a cold or flu (coughing, fever, difficulty breathing, running nose, etc), please reschedule your appointment for at least one month from now.
  2. Try not to touch any surfaces in the office you do not have to touch.
  3. If you are trying on glasses, DO NOT put the frames back on the shelf. Rather, we will collect them from you for proper cleaning before they are returned to the shelves.
  4. If you are ordering contact lenses, a year supply (and some 6 month supplies) order can be direct shipped to your home at no cost. Please take advantage of this so you don’t have to come into the office more than necessary.
  5. If you do need to come into the office for an adjustment, please call the office at 727-725-5558 when you arrive in your vehicle. We will let you know if there is a wait and will put you on a list so we can call or text you to come therefore minimizing the time you are in the enclosed space of our office.
  6. Please come to your appointment with the least number of people possible to reduce exposure to them and to others at the office.
  7. If you have any loved ones that have been exposed to the virus or certainly if they have symptoms of a respiratory illness, please wear a mask in case you are an asymptomatic carrier, or if possible, wait at least 4 weeks before coming in for non-essential care.

In an effort to protect you, here is what we are doing to help lower your risk:

  1. All surfaces in the office will be cleaned several times per day with antiviral/antibacterial cleaner. Surfaces in the exam room will be cleaned thoroughly in between each patient.
  2. No sick or symptomatic staff will be permitted to work while sick with a known viral respiratory infection or symptoms, or while directly caring for a sick relative/friend.
  3. For your safety, payments can be done ahead of time over the phone if you call ahead. This will decrease the amount of time you are in the store and your exposure risk in our enclosed space.
  4. No glasses frames other patients try on will be put back on display until the frames are cleaned with an antiviral cleanser.
  5. We are actively asking patients to reschedule for 4 weeks later if they have any symptoms themselves or in their family/ social network.
  6. We are giving options for patients to acquire goods by mail rather than coming into the store.
  7. We altering our schedule to decrease the number of patients that might be in the office at the same time to maximize social distancing.
  8. We are practicing frequent hand washing at our office to protect you and each other.
  9. We will ask patients to reschedule if they present to our clinic with a cough or other COVID-19 symptoms.

Thank you for your patience and understanding during this stressful and trying time. Let us all work together to lower risk of the spread so that less people die and less people have permanent side effects from COVID-19. Each of us can do our part. May God bless each of you and keep you well. Thank you for your understanding and care for your fellow humans.

Dr. Christopher K. Keats, OD
