Distance glasses are made for people who are nearsighted ( people who have difficulty seeing DISTANT objects but can see close objects clearly ) reading glasses are for people who are farsighted ( people who have difficulty seeing CLOSE objects but can see distant objects clearly ) Distant glasses come in a MINUS prescription and usually when you wear them, they make everything look SMALLER Reading glasses come in a PLUS prescription and they make the world seem BIGGER
People who are nearsighted have difficulty seeing objects that are far away clearly, but can see objects that are close more clearly. This is typically due to the shape of their eyeball or the focusing power of their eye's lens. Nearsightedness can be corrected with glasses, contact lenses, or refractive surgery.
Isaac wears glasses to correct his vision. They help him see more clearly by adjusting the way light enters his eyes, focusing it properly on his retina. Without glasses, Isaac may have difficulty seeing objects that are far away or up close.
You do if you have trouble seeing like blurry or double vision up close or far away or both
They are made up of a special transparent glass that helpes your eye focus in on close or far away things.
Neither. Being unable to see objects far away is being nearsighted (US English) or shortsighted (British English); you can see things a short distance away. Being unable to see things that are close to you is being farsighted or longsighted. Most people as they age develop the inability to see things close to them and require 'reading glasses' to magnify close items.

Because they are bifocals. Bi=two. The lower half lets you see things Close, the upper half lets you see things farther away. Like two glasses in one.
Near-sided vision is when you can see things close to you but not far away. You need glasses to see things far away. I know this because I am near-sided. Hope this helps you out.
You can wear any glasses you want so long as the prescription is right for your eyes. There are no glasses that will make your color blindness go away if that's what you're thinking.
