What is the definition of blindness?

The definition of blindness is most accurately represented by the inability to see. This term encompasses a broad range of vision impairments, but when referring specifically to blindness, it typically indicates a complete lack of visual perception.

While partial loss of vision, total inability to perceive light, and difficulty in focusing represent various visual impairments, they do not fully capture the essence of what is conventionally understood as blindness. Partial loss of vision indicates some level of sight remains, and total inability to perceive light suggests a more specific medical condition, often associated with profound visual impairment, rather than the broader term blindness itself. Difficulty in focusing refers to issues related to clarity of vision rather than an absence of vision.

Thus, defining blindness as an inability to see encompasses a full spectrum of individuals who may not have any light perception, providing a clear and holistic understanding of the term.
