Which condition often affects one eye and results in decreased vision?

Monocular vision typically refers to the use of one eye instead of both, which can lead to decreased depth perception and may make objects appear differently than they do when viewed with both eyes. It can result from various factors, including conditions that affect vision in one eye, potentially leading to the reduced ability to see with that eye.

While strabismus (misalignment of the eyes) can affect visual acuity by causing one eye to be less functional, it does not exclusively define a condition where one eye is impacted at the level of decreased vision. Similarly, retinal detachment is a serious medical emergency affecting the retina and may result in severe visual impairment, but it is categorized more specifically and often requires immediate surgical intervention. Red eye, which typically results from irritation or inflammation of the eye, may not inherently lead to decreased vision without underlying conditions. Monocular vision encapsulates the effect on visual perception when one eye is not used effectively, leading to outcomes associated with diminished vision integrity.
