Nearsighted vs. Farsighted: Treating Common Refractive Errors
Roughly 194 million Americans and over 1.4 billion people worldwide wear glasses or contact lenses, according to The Vision Council. It’s estimated 75% of adults currently require, or will require, vision correction at some point in their lives.
While there are a number of reasons people wear glasses, most often it is to correct what is known as a refractive error. The National Eye Institute defines a refractive error as a vision issue that occurs as a result of changes in the shape of your eye that prevents light from correctly focusing on the retina. As a result, images often become blurred, distorted, and out of focus while also contributing to physical discomforts including headaches, double vision, and eye strain.
