Monovisão

Monovisão, also known as monocular vision, refers to the visual perception achieved when only one eye is functional or used for sight. This condition can result from injury, congenital conditions, or surgical procedures such as enucleation or ophthalmic repair. Monovisão differs from binocular vision, which involves the combined input from both eyes, enabling depth perception and a broader field of view.

Individuals with monovisão typically experience a reduced field of peripheral vision, often around 150 degrees compared to approximately 180 degrees in binocular vision. Depth perception may be compromised, making tasks that require precise distance judgment more challenging. However, many people adapt to monovisão over time, developing compensatory strategies that improve spatial awareness and visual tasks.

In practical terms, monovisão influences daily activities, such as reading, driving, and navigating complex environments. It can increase susceptibility to visual blind spots and make it more difficult to detect objects coming from the non-visual field of the unaffected side. Despite these limitations, certain skills and adaptations can mitigate adverse effects, including enhanced head movements and reliance on monocular cues like size, texture, and motion.

There are various causes of monovisão, including trauma-induced loss of an eye, congenital monocular vision, or medical interventions for eye diseases. Treatment focuses on maximizing the use of the remaining eye and adapting to the visual field limitations. Supportive devices, therapeutic exercises, and environmental modifications can help individuals with monovisão maintain independence and safety.

Overall, monovisão is a condition reflecting the absence or non-use of binocular vision, often requiring adaptive strategies but still allowing individuals to navigate and interpret their environment effectively with appropriate support.
