Blindness is a condition characterized by the loss of vision or the inability to see. There are different levels of blindness, ranging from partial to complete loss of vision. Blindness can be caused by a variety of factors, including genetic conditions, eye diseases, trauma, or other health conditions.
Blindness can be classified into two main categories: legal blindness and total blindness. Legal blindness is defined as having visual acuity of 20/200 or less in the better eye with corrective lenses or a visual field of 20 degrees or less. Total blindness, on the other hand, is the complete loss of vision.
Blindness can have a significant impact on a person’s life, including their ability to perform daily activities, work, and socialize. However, with the help of assistive technologies such as braille devices, screen readers, and mobility aids, people who are blind can still lead fulfilling lives.
It is important to note that blindness is not just a physical disability, but also a social and cultural one. People who are blind often face discrimination and barriers to accessibility, making it important for society to work towards creating more inclusive environments.
