Hearing loss refers to a partial or total inability to hear sounds, which can result from aging, exposure to loud noises, or medical conditions. It can affect one or both ears and may lead to difficulties in communication and social interactions. Common types include conductive hearing loss, sensorineural hearing loss, and mixed hearing loss. Vision loss involves a decrease in the ability to see, which can range from blurred vision to complete blindness. Causes include aging, eye diseases like cataracts or glaucoma, and injuries. Vision loss can impact daily activities, making it challenging to read, drive, or recognize faces.
