The word 'eyesight' is used to talk about how well someone can see with their eyes. It's usually used when talking about whether someone needs glasses or if they have good or bad vision. For example, if someone says "I have bad eyesight," they mean that they can't see very well and might need help from glasses, contacts or surgery. It's a useful word to describe one's visual abilities or any problems related to vision.
