For you and others who can read this piece of content, a sense of vision doesn’t sound anything different. Imagine someone who cannot see, the world is a little harsh to them. It is crucial to provide the right amenities to someone who is visually impaired. To someone who cannot see, Braille is nothing short of bliss. Ages ago, Louis Braille came up with the Braille system of reading and learning for the blind. The system came as a boon for all the virtually challenged people across the globe and to this date, the system remains unchanged. Louis was born on 4th January 1809, and the world celebrates the day as National World Braille Day. The entire month of January is dedicated to raising awareness on the significance of the Braille system for the blind and visually impaired. As we trip through the blog, we shall understand aspects of blindness like low vision causes and more.

Central vision loss -A blind spot found in the center of vision.
Peripheral vision loss:When a person is not able to see anything above or below the eye levels, though the central vision doesn’t alter.
Night blindness:When a person has problems in seeing in poorly lit places like cinema halls, roads with no street lamps etc.
Blurred vision:A situation when objects both far and near are out of focus.
Hazy vision:The area of vision seems to be covered with a film.
