Sensory keenness refers to the sharpness and sensitivity of an individual's senses, such as vision, hearing, taste, touch, and smell. As individuals age, their sensory keenness tends to decline gradually.
This term refers to the process by which our sensory receptors become less sensitive to constant or repetitive stimuli over time.
Presbyopia: Presbyopia is a condition that occurs with aging where there is a gradual loss of the eye's ability to focus on nearby objects due to changes in the lens.
