Why Do Blind People Wear Sunglasses?
Improve vision
Wearing sunglasses can help blind people improve their vision. In the vast majority of legally blind people, there is some degree of vision. Sunglasses may be able to help some individuals with limited vision enhance their capability to see.
Legal blindness is a condition where the central acuity of your vision is less than 20/200 in your better-seeing eye even if you wear corrective lenses. It means you need at least 20 feet to be able to see an object as clearly as a person that doesn't have vision impairment at 200 feet.
Sunglasses may help patients with limited vision by reducing glare. A glare that takes up only a small part of a person's visual field may occupy almost all of a blind person's visual field.
People with photophobia, also known as light sensitivity, have a tendency to experience photophobia. Sunglasses can help people with photophobia protect the eyes from bright lights that may cause discomfort or further damage.
Sun protection
Blind people are also vulnerable to UV rays just like normal people'. For visually impaired individuals with at least some degree of vision, sunglasses might help reduce further vision loss due to exposure to UV exposure.
Completely blind people can experience pain in bright lights, even though they cannot see them. This phenomenon has been described in headache patients whose vision is completely impaired.
Particles, dust and injury protection
Sunglasses also protect a blind person's eyes from external objects while providing them with protection from bright light.
Individuals whose eyes are impaired have an increased danger for acquiring foreign objects in their eyes. For instance, a nearby open door or a low-lying tree branch can be painful to enter unexpectedly. Blind people also feel pain as much as a regular person if their eyes are injured.
Air particles, such as dust or pollen, could cause irritation to an individual's eyes. Wearing sunglasses can help act as a protective barrier to reduce the amount of those particles that gets into the eye of a blind person.
To communicate blindness
Usually the sight of someone wearing a white cane with sunglasses is an unmistakable sign that they are blind. Some people who suffer from blindness choose to wear sunglasses, to communicate the occurrence to others.
Communicating a lack of vision encourages people to adopt potentially useful habits, such as staying a safe distance from large groups of people.
Fighting the stereotype
Besides covering the eyes, wearing sunglasses is the norm for many blind people for a few reasons. Protective eyewear may help avoid eye damage and maximize the field of view.
Some people might wear sunglasses out of a sense of self-preservation to intentionally cover up their eyes. Blind people might feel uncomfortable displaying their eyes or want to reveal their emotions better with their associates.
Some blind people sometimes have difficulty sustaining eye contact, and some individuals find that wearing sunglasses makes others feel more comfortable.
Why Do Blind People Need Black Glasses?
The reason why blind people need black glasses is because blind people are incredibly sensitive to bright lights may be in pain in or around their temple area, and may also suffer from a burning sensation in the eyes or buzzing sound. Lens sunglasses prevent bright light from occurring, thereby lessen the pain.
Why Do the Blind Wear Red Glasses?
Blind people wear red glasses because they let others know that they are visually impaired. In addition to using a cane, blind people are able to communicate with their problem by using red glasses.
