Charting the need for eyeglasses: 10 signs you should get an eye exam

We cannot spell the word “glasses” without an “a” and an “e.” But if you have trouble telling these two letters apart, does it mean you actually need vision correction?

Chances are it means you should have an eye exam. Roughly 60% of the world’s population requires vision correction, according to the Vision Impact Institute. That’s a lot of people, but the good news is 80% of all visual impairment can be avoided or corrected. In fact, 75% of Americans use some sort of vision correction. 3

Figuring out if you need glasses is simply a matter of understanding the symptoms of vision loss. Following are 10 signs that you might need vision correction and should schedule an eye exam.

While the presence of one or more of these signs may not mean a vision problem, an eye exam is recommended to be safe. An eye doctor can help you understand what is causing these changes.
