Final answer:
Inaccurately determining interpupillary distance can lead to vision problems like presbyopia and hyperopia, affecting binocular vision and the ability to focus on close objects. Presbyopia, often occurring with age, is caused by reduced elasticity in the eye lens or weakened muscles.
Step-by-step explanation:
Failure to accurately determine the interpupillary distance over time will cause vision problems and can result in a decreased ability of the eyes to work together in binocular vision.
One common vision problem associated with such issues is presbyopia, which is where the eye gradually loses its ability to focus on close objects, primarily as a result of aging.
Presbyopia involves the eye lens becoming less elastic or the muscles controlling the lens losing power, leading to difficulty focusing on small objects and reading fine print, typically noticed between ages 40-50.
Moreover, inaccurate determination of interpupillary distance can also contribute to hyperopia, which is farsightedness, where the eyes are unable to converge the rays from a close object by the time they strike the retina, producing blurry near-field vision.
This vision defect might occur due to insufficient power in the lens or the eye being too short.
