eyesight

Eyesight is the ability to see clearly. Think of a hawk soaring high above: its eyesight is so sharp that it can spot tiny prey from far away. But this ability can change over time. A child may see very clearly, while an older person may need glasses to help them see better. The word is usually used in a literal way. It refers to how well someone can see the world around them, especially how clear and sharp things look.

Eyesight refers to the ability to see clearly and accurately. It is not just about having eyes, but about how well they work when you look at the world around you. Good eyesight helps you notice details, judge distance, and see shapes, color, and movement.

The word is most often used when talking about how sharp or clear someone's sight is. We often speak of poor eyesight when a person has trouble seeing and may need glasses or contact lenses. Nearsightedness, farsightedness, and astigmatism are common problems that can affect eyesight.

It is useful to distinguish "eyesight" from the broader word "vision." "Vision" can sometimes describe ideas, plans, or imagination, but "eyesight" almost always means actual physical sight. If you say someone has good eyesight, you mean they can see well, not that they have good ideas about the future.

So whether you are talking about reading small print, recognizing a face across the street, or noticing something far away, "eyesight" is the everyday word for a person's natural ability to see.
