    There are two sides of eye problems: myopia and farsightedness. With age growing, most old men will get the farsightedness which means that they need to entail strenuous effort on seeing the near things. However, they can see clearly at the far things. That is the function of reading glasses for most old men when reading or seeing near things.

    Of course, it's necessary to wear a pair of reading glasses when someone has reading, especially for the people who have been getting older. As we know that when someone get older, they often have to get the eye problem which is called farsightedness. So by wearing reading glasses, they can effectively make an image at near appear larger. By dong this, they help your eye relax so it is not straining while viewing small close stuff, like a magazine, a computer screen, or that portfolio of papers. So, you should pay more attention to this problem, so that one day you can also buy one for your parents.
