Blindness is a condition where a person lacks or loses their ability to see completely or partially. It can be caused by various factors such as eye diseases, injuries, or conditions affecting the optic nerve or brain. Blindness can range from mild visual problems to complete loss of sight. People who are blind may use alternative techniques and tools to navigate their surroundings, such as using a cane or guide dog, reading in braille, or using assistive technology. While blindness can significantly impact daily life, many individuals adapt and lead fulfilling lives with the support of specialized services and resources.
