A boon for the Color Blind!
What is color blindness?
Color blindness affects about 1 in 12 men and 1 in 200 women. It’s caused by an inherited condition that causes your eyes not to distinguish specific wavelengths of light.
The most common form of color blindness involves red-green deficiencies or blue-yellow deficiencies.
A Little History about the evolution of color Blind Glasses.
The first recorded use of colored lenses was in ancient Egypt around 3000 BC. The Egyptians used green glass to treat cataracts. In medieval times, people wore amber spectacles because it helped them see better at night. By the 1800s, scientists experimented with different materials such as iron oxide and silver nitrate to create tinted eyeglasses. However, these early attempts did not produce satisfactory results.
John Dalton’s studies have contributed to the modern-day innovations in color
vision technology and the invention of glasses for the colorblind, such as the Enchroma lenses invented in 2002. Enchroma lens technology offers a simplified differentiation of colors and increases the contrast of red and green colors.
What are the symptoms of color blindness?
Color blindness usually doesn’t cause any severe health issues or physical changes. But some people may notice other things like trouble reading labels on food cans or clothes because they’re difficult for them to distinguish from one another.
How do I know if I’m colorblind?
You might be colorblind without even knowing it. If you think your eyesight isn’t as sharp as usual, talk to an eye doctor right away.
How do Color blind glasses Help?
The glasses help by enhancing the colors that we see around us. The lenses contain a special coating that helps filter out all wavelengths except those corresponding to the spectrum of light our eyes perceive as visible. This is done so that your brain gets an accurate representation of what’s going on outside.
They help in the following things :
In identifying colors that may not be readily apparent to your eyesight. This is especially helpful when trying to identify a particular shade of clothing, food items, etc.
The ability to see more details on objects such as textiles, patterns, graphics, etc.
Better visual acuity reduces glare from light sources like sunlight, fluorescent lights, LCD screens, computer monitors, etc.
Things to take Care of:
The lenses should not be worn while driving a vehicle as they may cause distraction. The wearer must also avoid wearing them when doing any work that requires concentration on details such as reading fine print etc.
