Enchroma glasses are made of plastic and they have been around since the early 2000’s. They were originally designed for use with computer monitors. However, these days they are available in different sizes to fit all types of eyes. Enchroma color correction glasses come in several colors and can be used for various purposes such as reading, driving or even working at a computer screen.
The most common uses for enchroma glasses are:
1) For correcting red-green color blindness (also known as Deuteranopia).
Red-Green color blindness is a rare condition where the brain does not perceive certain wavelengths of light correctly. These colors include red, green and blue. The problem occurs when the eye sees these colors mixed together incorrectly resulting in reduced contrast between objects and images.
2) For correcting nearsightedness.
Nearsightedness is a type of astigmatism which affects how your eyes focus on close up objects. The effect is similar to having two small pinholes in one’s field of vision. This condition causes blurred vision, double vision or “seeing” things that aren’t there.
3) For correcting myopia (nearsightedness).
Myopia is a common condition which causes objects to be blurred when they are looked at. This blurred vision is caused when light focuses in front of the retina rather than on it. Myopia is also known as short sightedness.
4) For correcting farsightedness.
Farsightedness is a common condition where objects that are far away from you are blurry while close up vision is unaffected. This occurs when light focuses behind the retina rather than on it.
Enchroma color blindness glasses are also available in various styles to fit your specific needs. For example, if you are a professional driver or pilot, you can purchase computerized eyewear which automatically darkens when it senses bright light. Different frames are also available so you can choose the ones which best suit your face.
Some people worry that enchroma glasses won’t help them because they have a more severe form of color blindness. This is untrue. The glasses are beneficial to all types of color blindness and will improve your vision greatly. If you feel that your vision isn’t up to standard then the glasses will make a big difference.
The only people who shouldn’t use these glasses are those with total color blindness (also known as monochromacy). This is a rare condition which affects less than 1 in 30,000 people.
