Complete blindness is a medical condition characterized by the total inability to perceive any form of visual stimulus. It refers to a complete absence of visual perception and the inability to distinguish light, color, or any visual information. Individuals with complete blindness experience a total loss or absence of vision, rendering them unable to see the world around them.
This condition can be caused by various factors, including congenital abnormalities, eye injuries, or diseases affecting the eyes or visual pathways. Some common causes of complete blindness include severe retinal damage, optic nerve damage, advanced glaucoma, cataracts, or acquired brain injuries affecting the visual cortex.
People with complete blindness heavily rely on their other senses, such as hearing, touch, and smell, to navigate their surroundings and process information. They often use assistive devices, such as white canes or guide dogs, to aid in their mobility and independence.
While complete blindness implies the absence of visual perception, it is important to highlight that individuals may still possess some degree of light perception or have the ability to differentiate between light and darkness. However, they are unable to form visual images or recognize shapes, objects, or colors.
Various rehabilitation techniques and assistive technologies are available to support individuals with complete blindness in their daily lives, facilitating their independence and participation in society.
The word "complete" originates from the Latin word "completus", which is the past participle of the verb "complere", meaning "to fill up" or "to finish". The term "blindness" comes from the Old English word "blindnes", which is derived from the Proto-Germanic word "blendan", meaning "to make blind" or "deceive". So, the etymology of "complete blindness" is a combination of the Latin word implying fullness or totality and the Old English term for the state of being unable to see.
