Final answer:
Visual acuity loss and blindness are considered impairments, which can lead to disabilities affecting one's ability to perform daily tasks. Accommodations help provide equal access and opportunity for those with visual disabilities.
Step-by-step explanation:
Conditions resulting from lost visual acuity or disability are known as impairments. An impairment refers to a loss of function or abnormality in body structure or mental functioning. In the context of visual acuity, poor eyesight, or blindness would be considered an impairment. This can lead to a disability, which describes a reduction in one's ability to perform everyday tasks due to these impairments. For example, students with visual impairments might struggle with reading notes or their handwriting, leading to difficulties in learning and potentially causing headaches from eye strain. The appropriate accommodations, such as Braille signs and sidewalk ramps, help provide access and opportunity for individuals with visual disabilities.
