Visual disabilities refer to a range of conditions that affect a person's ability to see. This can include partial sight, where individuals may have limited vision, or total blindness, where there is no vision at all. Common causes of visual disabilities include cataracts, glaucoma, and retinal disorders. People with visual disabilities often use tools like braille or screen readers to assist with reading and navigation. Hearing disabilities encompass various levels of hearing loss, from mild to profound. Individuals may struggle to hear sounds or understand speech, which can impact communication. Causes of hearing disabilities can include genetic factors, age-related hearing loss, and exposure to loud noises. Many people with hearing disabilities use hearing aids or sign language to enhance communication and connect with others.
