How to know if i need eyeglasses with 20/60 vision?

Get checked: If you know you have 20/60 vision, then I assume you have been tested on a visual chart. The way to determine by yourself if eyeglasses might help is to use a needle to punch a few holes in a black sheet of paper, and then look at some object at a distance that seems blurry. If the image clears up while looking through the holes, then eyeglasses can improve the vision.
