<h3>What physical characteristics are most prevalent?</h3>
Height, weight, hair color, and skin tone are just a few of the physical traits that you could find prevalent among people. But a select handful stick out more than the others. Face and ocular characteristics are some of these.
Both daily tasks and safety considerations require good eyesight. In instance, having clear eyesight might make it easier for you to read signs correctly and prevent mishaps or injuries. The ability to drive a car or handle machinery safely can also be improved by having good vision.
