Did you know that as many as 8% of men and .5% of women who have Northern European ancestry have the most common form of red-green color blindness? What does it mean to be color blind and if you have this condition, can the Oxy-Iso color blind glasses from Vino Optics help you? Keep reading to find out.
What is color blindness and what causes it?
Most of us share a common color vision sensory experience. Some people, however, have a color vision deficiency, which means their perception of colors is different from what most of us see. The most severe forms of these deficiencies are referred to as color blindness. People with color blindness aren’t aware of differences among colors that are obvious to the rest of us. People who don’t have the more severe types of color blindness may not even be aware of their condition unless they’re tested in a clinic or laboratory.
Inherited color blindness is caused by abnormal photopigments. These color-detecting molecules are located in cone-shaped cells within 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 kinds of color blindness, based on photopigment defects in the three different kinds 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 absence of color vision —total color blindness – is rare.
What are Vino Optics Color Blind Glasses?
They are special glasses that were originally designed to help doctors, paramedics, nurses, etc. with red-green color blindness to see health signs like veins. The lenses in the glasses amplify the perception of oxygenation of blood under the skin, allowing color deficients better perception of veins, erythema, and other health states.
Except for the deep pink or purple-tinged lenses, the glasses don’t appear to be 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 one plate from an Ishihara Color Test. If you’re color blind you probably can’t see it. But when you put on the Vino Optics color blind glasses, you may be able to see it. I say “may” because the glasses don’t work for everyone even though the Vino Optics web site says that they can correct color blindness for everyone. I didn’t find this to be an accurate claim. Granted, I only conducted three tests with the glasses. One test with my a 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 problems seeing every number in the Ishihara Color Test linked above. When I put on the Vino Optics glasses, the only thing I noticed was that everything had a deep pink hue and some colors like blue and yellow appeared to be brighter, almost glowing.
For the next test, I took the glasses to work and had someone who I knew was color blind take the Ishihara test. He was able to correctly guess the numbers or trace the wavy lines in only one or two of the plates, but when he put on the glasses he was able to guess almost all the plates. However, when I asked him to tell me the colors of various objects around the office, he still didn’t know the colors.
For the last test, I asked my dad to take the Ishihara test. He was only able to get one plate correct (the one pictured above). And when he put on the glasses, it did not help him guess any the numbers of any more of the Ishihara plates. He did say that some colors were brighter, but when I asked him to tell me the colors for some objects, he would say that 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 the way I do. I was hoping that the Vino Optics Oxy-Iso color blind glasses would allow my dad to experience some colors for the first time but unfortunately, they didn’t work for him. They did help my friend at work pass the Ishihara color test, but he didn’t really seem to find the world around him to be any more vibrant or exciting while wearing the glasses.
Since these glasses didn’t help my dad, I can’t recommend them for everyone who has red-green color blindness. If someone else decides to purchase a pair, let me know what you think. I hope you have better luck!
