What is a key feature of Amblyopia?

• A. Vision in both eyes is good
• B. Loss of vision in one eye
• C. Both eyes appear normal
• D. Development of night vision

Answer: (B)

Amblyopia, commonly known as "lazy eye," is characterized by a reduction in vision in one eye due to abnormal visual development during childhood. In this condition, the brain does not fully acknowledge the images received from one eye, which can lead to significant vision impairment in that eye. This typically results from various factors, such as strabismus (misalignment of the eyes), refractive errors, or other visual impairments that affect how the brain processes visual stimuli. When considering that vision in both eyes is generally not "good" in the case of amblyopia, it’s important to note that the affected eye often has poorer visual acuity compared to the fellow eye. The other options do not accurately represent the defining characteristics of amblyopia. For instance, while both eyes may appear normal upon external examination, the functionality of the affected eye has been compromised, leading to a notable difference in visual performance. In contrast to night vision development, which is unrelated to amblyopia, this condition specifically pertains to the underdevelopment of vision in one eye. Thus, loss of vision in one eye encapsulates the essence of amblyopia effectively.
