Which of the following is a common cause of visual impairments?

Refractive errors are indeed a common cause of visual impairments. These errors occur when the shape of the eye prevents light from focusing directly on the retina, resulting in blurred vision. Common types of refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These conditions can be corrected with glasses, contact lenses, or refractive surgery, making them prevalent among visual impairment causes.

Muscular dystrophy primarily affects muscle function rather than directly causing visual impairments. Attention deficit disorder and autism spectrum disorder are neurological and developmental issues, respectively, with no direct link to causing visual impairments. Thus, refractive errors stand out as a primary and treatable source of visual impairment in individuals.
