Everyone will eventually have problems with presbyopia. Young eyes have a great auto-focus mechanism that allows kids to see clearly up close, but this auto-focus declines over time. Sometime in their 40s, most people cannot see up close as comfortably or as clearly as they once did, and this is known as presbyopia. This vision problem will eventually stop changing around the mid-to-late 50s and is easily fixed with glasses such as readers or bifocals. Contact lenses are sometimes used but laser eye surgery is almost never used to help with presbyopia.
