Visual impairment is a term experts use to describe any kind of vision loss, whether it's someone who cannot see at all or someone who has partial vision loss. Some people are completely blind, but many others have what's called legal blindness. They haven't lost their sight completely but have lost enough vision that they'd have to stand 20 feet from an object to see it as well as someone with perfect vision could from feet away.
People rarely lose their eyesight during their teen years. When they do, it's usually caused by an injury like getting hit in the eye or head with a baseball or having an automobile or motorcycle accident.
Some babies have congenital blindness , which means they are visually impaired at birth. Congenital blindness can be caused by a number of things — it can be inherited, for instance, or caused by an infection like German measles that's transmitted from the mother to the developing fetus during pregnancy. If you, your parent, or your doctor suspects a visual problem, you'll probably pay a visit to an ophthalmologist pronounced: af-thal-MAH-luh-jist , a medical doctor who specializes in examining, diagnosing, and treating eyes and eye diseases.
When someone goes for an examination, the ophthalmologist will look at the structure of that person's eye. If your doctor determines that you have an eye condition that is likely to cause visual impairment, many treatments are available. Options may include eyeglasses, contact lenses, and eye drops or other medicines. In some cases, surgery may be required.
For instance, cataracts are often treated by removing the clouded lens and replacing it with an intraocular lens an artificial plastic lens that requires no special care and restores vision.
Other methods can compensate for vision loss. Guide dogs can help people get from place to place independently. Braille allows those with visual impairment to read and write.
Special equipment such as microscopic and telescopic glasses and voice-recognition software can make school and homework easier. Just as you don't think about your eye color every day, people with visual impairment don't always think about their condition every day either.
The partially sighted student meets the challenge of disability in much the same way as a totally blind student. Accommodations include the use of readers, audio taped texts, and raised-line drawings. Some partially sighted students can take notes in class by printing very large with a felt tip pen or marker; others will tape record lectures for later use.
Visual impairment can improve with glasses or other types of adaptive technology such as CyberEyez. Many blind and visually impaired people adjust to their disabilities. They work, go to the movies, explore new parts of town, and even win national talent contests.
