The science behind LASIK

"The human eye is a remarkable organ that allows light to enter, focuses it with the lens, and processes it through the retina to produce sight."

"Corrective lenses in the form of eyeglasses were our only option for vision impairment until the 20th century, when contact lenses emerged as a popular alternative."

"LASIK, a form of laser eye surgery, has transformed vision correction by providing a new option for millions of patients suffering from refractive errors."

"Understanding the anatomy and functionality of the eye can help inform choices regarding corrective options such as eyeglasses, contact lenses, and LASIK surgery."

The human eye functions by allowing light to enter, focusing it with a lens, and processing it through the retina to form images. Some people experience vision problems such as farsightedness, nearsightedness, or astigmatism. Historically, eyeglasses were the primary solution until contact lenses became popular in the 20th century. Recently, LASIK surgery has emerged as a transformative option for correcting vision impairment. Understanding eye anatomy is crucial for making informed decisions about vision correction methods including eyeglasses, contact lenses, and LASIK surgery.
