You may have the misconception that a person with blindness has no vision at all. However, that is not true. So, how much is a person with blindness able to see? A person is considered to be blind if they cannot see at all, whereas a person with partial blindness may experience blurry vision. A person is legally blind if they have a 20/200, meaning that they can see from only 20 feet away. However, legal blindness is not a medical term. Medically, blindness can range from mild to severe. An eye specialist is the best person to know whether a person is affected by blindness or not.
Here are some important facts that will broaden your understanding of blindness:
1. Blindness varies from mild to severe: A person with complete blindness will not be able to see anything. However, a person who is partially blind may experience cloudy vision, difficulty in differentiating shapes, and poor night vision among many other symptoms.
2. Eye diseases can also cause blindness: Glaucoma, cataracts, and macular degeneration are among the few eye diseases that could cause conditions leading to blindness. Seeking immediate medical attention could help in preventing the complete loss of vision. A stroke might also lead to blindness while optic neuritis may result in temporary or permanent loss of vision.
3. Babies can also have vision impairment at the time of birth: Though a child’s visual system starts developing in the womb, it is not until the age of two, that a child’s vision is fully developed. A child may have vision impairment at birth as a result of a medical condition. Neurological conditions, genetic conditions, and illness at the time of birth may cause partial or complete blindness in children.
4. Eye infections and other medical conditions can cause blindness in infants: Infections like conjunctivitis or medical conditions such as cataracts, congenital glaucoma, and strabismus might hinder a child’s visual system to develop fully. A child with vision impairment may possess normal-looking eyes. However, if they are not focusing on objects by the age of 4 weeks or 5 weeks, or not smiling at familiar faces by 6 to 8 weeks, then the parents should seek doctor’s advice. An older child may hold objects very close to his or her eyes, and exhibit clumsy behavior.
5. Blindness can be treated in some cases: In some cases, partial blindness can be restored with the help of surgery, medications, and eyeglasses. In cases where vision cannot be restored, the doctors help patients to adapt a sustainable lifestyle, to help them function with limited vision. In the case of people with complete blindness, the doctor may suggest the use of braille, audio clocks, audiobooks, and other aids.
