If you're able to see objects up close better than those that are far away, you may be nearsighted, a condition called myopia. The problem happens when light focuses in front of your retina instead of on it, making faraway objects look blurry. Glasses, contacts, or laser surgery may help you focus better.
Myopia (Nearsightedness)

When you can see nearby objects, but not those far away, you are nearsighted -- that is, you have myopia. It's a common condition that tends to run in families, and with glasses or contact lenses is easily corrected.

1 AnswerDr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answeredMany researchers believe that the reason why so many people are nearsighted (meaning they can't see far away) is because we don't need distance vision anymore.
Several generations ago, nearsightedness was nearly unheard of among Alaskans, because they were continually looking out to the horizon for information about the weather. Two generations later, and with the incarnation of TV and computers, 30 percent of Inuit kids are nearsighted. Similarly, the Nepalese people believe that those with problems seeing distance should stare at the moon to help exercise and train their eyes to see far away.
