The lenses used in the corrective eyewear used for people with Irlen Syndrome are designed to correct the refraction of light entering the eye. This helps to reduce or eliminate the symptoms of the condition. The color of the corrective lenses will usually be amber, blue or green.
There are two types of Irlen Syndrome: dyslexia and visual stress.
There are two main types of corrective eyewear for people who have Irlen Syndrome: amber-tinted eyeglasses, which filter out blue light, or green-tinted eyeglasses, which filter out red light. As a result, the brain receives less information about the color blue or red, which helps the brain understand color and the relationship between color and letters.
Irlen Syndrome glasses help to reduce the impact of the sensory overload that can cause difficulty in many academic, social, and personal situations.
In addition to the physical appearance of the lenses, the design of these eyewear also plays an important role in the way in which they reduce the impact of the sensory overload. The lenses are curved and have a high index of refraction. The combination of these two component parts of the eyewear make the light passing through them travel a shorter distance in your eyes than it would without the lenses. This provides your brain with less sensory input and less reaction from your eyes.
The way in which the glasses correct vision is different from bifocal glasses or contact lenses.
The lenses in these glasses are made of a special material that filters out certain wavelengths of light. This allows the brain to process the images that reach it correctly. This means that your eyes can focus on near and far objects without straining, and that you will not experience discomfort or headaches when working with electronics.
Addition to the normal appearance of the glasses, the frames have a distinctive design that allows them to be easily identified.
The thin wires that frame the lenses are configured to stimulate the brain to process information more slowly than normal. This allows the brain to receive more information about colors and shapes, making reading and writing easier. Over time, the brain can learn to process information more quickly without the frames.
The lenses are tinted a light gray and have a slight bluish tint to them.
If you have difficulty reading or concentrating because of a sensitivity to certain colors, you may be trying to solve your problem with the wrong solution. The red-green color blindness that is the most common form of color blindness cannot be corrected with glasses. The same is true for color blindness caused by aging. Fortunately, however, there is a way to improve reading and concentration by wearing special eyeglasses. These glasses have filters that block certain colors from reaching your eyes. As a result, your brain receives a different color of light which helps you to understand color better.
The glasses have a number of characteristics that enable them to help persons with Irlen Syndrome see better.
People with Irlen Syndrome are born with a visual perceptual deficiency that affects the way they visually perceive the world. There are two main types of perceptual organization: organization by color and organization by form. Most people use one or the other of these methods for organizing the world around them. People with Irlen Syndrome use neither. They process the information they receive through their senses differently from most people. As a result, they often struggle to see distinct colors, lines, or shapes.
For some, the glasses provide relief from the constant feeling of visual stress.
The lenses in these glasses have a special blue-green tint which reduces the perception of color – making bright colors seem less bright, and darker colors more muted. These types of corrective lenses are known as “tinted lenses”.
Conclusion
Currently there are no approved prescription products to treat the effects of dyslexia, but there are several options available to help those who suffer from the disorder. One option is to use corrective eyewear to reduce the amount of light that enters the eyes and to compensate for the difficulties reading for some people with dyslexia.
