The human eye is able to see because the lens focuses light on the retina; ideally, it will be centered on the retina for clear vision. However, many people have refractive disorders that can prevent light from falling where it needs to.
This video explains the refractive disorders, which include myopia, hyperopia, and astigmatism. With myopia, the eye is too short, so objects far away appear blurry. Hyperopia is just the opposite, as the eye is too long. Astigmatism occurs because the cornea is misshaped, so there are multiple focal points in an image creating blurry vision in all fields.
LASIK eye surgery can address all of these refractive issues so that you can see clearly without the need for glasses or contact lenses. Learn about your LASIK surgery options by visiting LASIK of Nevada. Schedule a consultation with us on our website or call (702) 636-2010.
