Did you know that up to 8% of men and 0.5% of women of Northern European descent suffer from the most common form of red-green color blindness? What does it mean to be colorblind and if you suffer from this condition, can Vino Optics Oxy-Iso colorblind glasses help you? Read on to find out.
What is color blindness and what are the causes?
Most of us share a common sensory experience of color vision. Some people, however, have a color vision deficit, which means their perception of color is different from what most of us see. The more serious forms of these impairments are called color blindness. People who are color blind are unaware of the differences in colors that are obvious to the rest of us. People who do not have the most severe types of color blindness may not even be aware of their condition unless they are tested in a clinic or lab.
Hereditary color blindness is caused by abnormal photopigments. These color-detecting molecules are located in cone-shaped cells inside the retina, called cone cells. In humans, several genes are needed for the body to make photopigments, and defects in these genes can lead to color blindness.
There are three main types of color blindness, based on photopigmentation defects in the three different types of cones that respond to blue, green, and red light. Red-green color blindness is the most common, followed by blue-yellow color blindness. A complete lack of color vision – complete color blindness – is rare.
What are Vino Optics color blind glasses?
These are special glasses that were originally designed to help doctors, paramedics, nurses, etc. with red-green color blindness see signs of health like veins. Eyeglass lenses amplify the perception of oxygenation of the blood under the skin, allowing color deficient people to better perceive veins, erythema and other health conditions.
With the exception of dark pink or purple tinted lenses, glasses don’t look that special.
They have a plastic frame and appear to be a relatively inexpensive pair of sunglasses.
Can you see the number in the center of the circle? This is just a plate of a Ishihara color test. If you’re color blind, you probably can’t see it. But when you put on Vino Optics color blind glasses, you may be able to see it. I say “can” because glasses don’t work for everyone although the Vino Optics website says they can correct color blindness for everyone. I did not find this statement to be correct. Granted, I only performed three tests with the glasses. One test with my friend at work, one with my dad and I tested them on myself even though I’m not color blind.
I was the guinea pig for the first test and had no problem seeing each number of the Ishihara color test linked above. When I put on the Vino Optics glasses the only thing I noticed was that everything had a dark pink tint and some colors like blue and yellow looked more vivid, almost shiny.
For the next test, I took the glasses to work and asked someone I knew color blind to take the Ishihara test. He was able to guess the numbers correctly or draw the wavy lines in only one or two of the plates, but when he put the glasses on he was able to guess almost all the plates. However, when I asked him to tell me the colors of various objects in the office, he still did not know the colors.
For the last test, I asked my dad to take the Ishihara test. He could only get one correct plate (the one pictured above). And when he put the glasses on, it didn’t help him guess the more numbers of Ishihara’s plates. He said some colors were brighter, but when I asked him to tell me the colors of certain objects, he said red was brown or gray. The only color he could guess about 100% of the time was blue.
Not being able to see colors seems unimaginable to me and it makes me sad to think that my dad doesn’t see things like me. I was hoping that Vino Optics Oxy-Iso color blind glasses would allow my dad to experience certain colors for the first time, but unfortunately they didn’t work for him. They helped my friend at work take the Ishihara color test, but he didn’t really seem to find the world around him more vibrant or exciting when he was wearing the glasses.
Since these glasses didn’t help my dad, I can’t recommend them to anyone with red-green color blindness. If anyone else decides to buy a pair let me know what you think. Hope you have better luck!
