Article: Poor eyesight is typically genetic. So if both of your parents wear glasses, it is reasonable to assume you'll need them eventually too. Keep this in mind as you consider whether or not you need glasses. Ask your family members how old they were when they first started wearing glasses. Think about whether or not your vision seems to have changed over the years. Do you have more trouble viewing specific things than you did in the past? This is a sign that you need glasses. Specifically consider whether you have trouble viewing things that are far away or that are up close, as these are the two biggest problems with eyesight that people typically have. The ultimate way to determine whether or not you need glasses is to get an official eye examination from a licensed optometrist. They will perform tests on your vision and on your eyes in general to determine if glasses are a necessity for you. An optometrist, in addition to whether or not you need glasses, will also be able to tell you if there are any medical problems with your eyes.

Consider your family history. Consider your vision. Consult an optometrist.
