Which are characteristics of a person who is nearsighted?

People that are usually nearsighted have lots of difficulty reading road signs from far distance, also have difficulty with seeing distant objects clearly, and this is obviously something dangerous for a person who has trouble with seeing from far. And the weird thing is, they might have that difficulty but in the other hand, they are able to see very well from close-up tasks such as reading a book or seeing the computer screen clearly. This disability is called "myopia".  In addition, people who are nearsighted also have difficulty seeing objects from far distance very blurry.   Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak.

I hope this helps answer your question! If you have options for this question, let me know k :) (Ask for help too)
