Those with Irlen Syndrome see the world differently. The way they see colors is different, and they have difficulty reading, especially black print on a white background and coloured text on a white background. The difficulty of reading is made worse by background noise, flickering lights, or bright light. Text that is too small or too high is also extremely difficult to read.
The way light reflects off of an object is known as its color.
People with iris defects often describe their vision as a colorless world or a gray, foggy world. This is because the color receptors in the eye are either completely missing or not functioning correctly. The result is a lack of color information in the brain, which affects the way these people see. While this is often a temporary condition, there are ways to help people with iris defects see better.
The color of a surface is affected by the light that hits it and the light that bounces off of it.
An estimated one in 20,000 individuals are affected by iris pigment disorders which can have a major impact on their vision and quality of life. One of the most common forms of iris pigment disorders is known as iris hypochromia which is a condition where the iris pigment is a darker color than normal. In some cases, the iris pigment is missing completely, creating an entirely white iris. This condition is known as iris achromatopsia.
Green is the color that light reflects off of something when it is shined onto it from the side.
A person with iris color disorders such as erythrophobia or trichromacy will see the world in shades of green. Other people who do not have this form of color blindness will see the world in shades of blue or purple. People with trichromacy can often see a sort of color “middle ground” that neither reds, blues, or greens can be seen. If you are wondering whether you have iris color disorders like this, talk to your doctor.
Light that is shined directly onto skin is called direct light.
People with Irlens Syndrome can see light that is shined directly onto their eyes. With corrective eyewear, they are able to see shapes and colors better as they develop an ability to see detail. These people’s vision is not perfect, though. They can see halos around lights, and images can appear confusing or distorted.
Light that is shined onto an object and then reflects off of it is called diffuse light.
People with iris transmisson loss (ITL) see the world the way a camera would—a bright, white, washed out world. Even if they wear corrective eyewear, objects still appear blurry, and people often describe their world as looking like it’s on TV. This condition can have a huge impact on a person’s daily life, whether it’s getting around town on their bike or trying to find the right medication in the pharmacy.
When the light hitting an object is a combination of both direct and diffuse light, it is called ambient light.
Like many people with iris-based photophobia, people with irlen syndrome see the world differently. While some are fully color blind, most have a reduced sense of color. They also have difficulty seeing contrast and detail. This means that bright colors can appear muted or dark colors can appear lighter than they really are. That means they will often struggle to read the colors on a traffic light or the color of food in a grocery store.
The color of the light that a person with Irlen’s Syndrome perceives is known as the color an object reflects when shined on from the side.
People with iridescence experience color differently than everyone else. When looking at an object, people without iridescence will see it as a single color. That’s it. A person with iridescence will see the object as a combination of colors that flicker and change based on how they are moving. For example, if you were to shine a red ball on someone with iridescence, they might see the ball as being yellow, green, blue, or a combination of all three.
Conclusion
Most people with irlen syndrome will see a difference between the amount of light that reaches the retina in bright light conditions and the amount of light that reaches the retina in darker conditions. This is known as hypochromatic iris. This condition causes reduced sensitivity to light, which leads to a reduced ability to see in bright light. As a result, most people with irlen syndrome will need to wear corrective eyewear during the day in bright light.
