Which of the following is a common visual disorder that may require vision training?

Amblyopia, commonly known as "lazy eye," is indeed a frequent visual disorder that may necessitate vision training. This condition typically develops in early childhood and involves the brain favoring one eye over the other, leading to reduced vision in the weaker eye. Vision training techniques, also referred to as vision therapy, are specifically designed to help improve the communication between the brain and the affected eye, ultimately strengthening the visual system and enhancing overall visual acuity.

These therapeutic exercises can include activities that encourage the use of the weaker eye, improve eye coordination, and enhance depth perception. In contrast, conditions such as nystagmus (involuntary eye movement), glaucoma (increased pressure within the eye that can lead to vision loss), and cataracts (clouding of the lens affecting clarity of vision) primarily involve structural or functional issues that may not respond to vision training. Instead, they often require medical intervention or corrective surgery to manage and improve vision.
