You probably associate a trip to the optometrist with having your vision tested, and it's true that figuring out how good your eyesight is is the part of the examination that takes the most time. It's not the only thing that's happening during an appointment, though! They're also testing your overall eye health and making sure there are no nascent problems that might affect more than simply your glasses prescription--and here's how they're doing it.

Although the eyes are one of the few resilient body parts, their location exposes them to the elements, including pokes, dust, and infections. While any of the elements can affect your eyesight, surgery can restore and improve your vision. The best part is that laser eye surgery is non-invasive and is often completed in a matter of minutes. However, eye surgery is still a surgical procedure; hence, post-operative care is vital.
