Why do blind people wear sunglasses? I’d wager that the majority of us have.
One of the most widespread misconceptions about blind people is entirely blind. In reality, only 15 percent of people with eye diseases suffer complete blindness. The remaining 15% can only view a small portion of the display.
A blind person may use sunglasses for a variety of reasons. Contrary to popular belief, most people use sunglasses to shield their eyes from harsh lighting and glare.
To better understand why blind people use sunglasses, as well as how they might benefit those with restricted vision, we’ll go a little further into this topic.
Why do blind people wear sunglasses?
1. Sunglasses can improve vision for blind people.
Blind people’s vision may be improved with the use of sunglasses.
The great majority of people who are legally blind have some degree of vision. Some people’s vision may be improved by wearing sunglasses.
In the United States, legal blindness is defined as a central visual acuity of 20/200 in your better-seeing eye with corrective glasses.
An item has to be at least 20 feet away from you to be seen with the same clarity by someone who does not have 20/20 vision while they are at a distance of 200 feet.
It is also possible to have legal blindness if your better-seeing eye has a visual field that is less than 20 degrees wide without shifting your eyes from side to side. To get an idea of what this might look like, you may poke a hole through a piece of paper using the tip of a pen and peek through.
Sunglasses may help people with restricted vision see by cutting down on glare. Nearly the whole field of vision for someone who is blind may be consumed by a glare that is hardly noticeable to the unaided eye.
Photophobia, or sensitivity to bright light, is a typical symptom among people who have lost vision. People who suffer from photophobia may benefit from wearing sunglasses to shield their eyes from strong lights that might cause irritation or worsen their vision.
2. Protection from the sun
Visible and blind people may have their eyes damaged or even destroyed by sunlight’s ultraviolet (UV) radiation. Cataracts and macular degeneration are made more likely by exposure to UV radiation. Blindness due to cataracts is the most frequent ailment that affects people all over the globe.
People who can see are equally as susceptible to UV light damage to their eyes as those who can. Sunglasses may assist those who are legally blind but still have some peripheral vision avoid additional vision loss due to UV radiation exposure.
Some fully blind people may sense discomfort while staring at bright lights, despite not seeing. This phenomenon has been found in people with migraines who have no rod or cone function.
3. To communicate blindness
The presence of sunglasses and a white cane is often interpreted as an indication of blindness. Some blind people may prefer to wear sunglasses to readily indicate blindness in specific settings.
Communicating blindness helps people adopt potentially beneficial actions, such as maintaining a safe distance in crowded settings.
4. Protection from particles, dust, and injury.
Along with protection from intense light, sunglasses may also create a barrier to shield a blind person’s eyes from foreign objects.
Foreign objects in the eyes are more likely to occur in the eyes of those who suffer from visual impairments. Things like open cabinet doors or tree branches might be uncomfortable to accidentally walk into.
Blind people can experience as much agony as sighted people if their eyes are scraped or harmed.
Air particles like dust or pollen may cause eye discomfort. Reduce the number of these particles getting into a blind person’s eyes by wearing sunglasses.
5. Aesthetic grounds.
Many vision-challenged people use sunglasses to make others comfortable, particularly while chatting. Because the eyes of a blind person may not be continually oriented in the direction of the sound source, it might be difficult for blind people to establish and maintain eye contact with others. This is another reason people shield their eyes with glasses to prevent embarrassment in conversation.
Some people lose their sight due to horrific incidents or injuries that may permanently scar or disfigure their eyes. Consequently, they want to conceal their eyes from people, particularly on social media.
As a result, several motivations exist for vision-challenged people to don dark sunglasses. It is widely thought that all visually challenged people are fully blind, although this is frequently not the case. They often have peripheral vision, which aids them in social situations and day-to-day activities.
Do blind people wear unique sunglasses?
It is pretty unusual for blind people to wear non-prescription (or Plano) sunglasses to protect their eyes from ultraviolet radiation and physical debris. Still, some may require something a bit more particular.
Some vision impairments, for example, may need the use of eyewear that blocks out particular wavelengths of light. And, again, not everyone who is visually challenged is entirely blind; hence, some may use prescription sunglasses to improve their sight.
Low-vision specialists can provide the most up-to-date electronic equipment and vision assistance.
Even though everyone’s vision demands are unique, it’s crucial to remember that blind people use sunglasses for the same reasons that the sighted do: to protect and enhance their eyes.
