LASIK Eye Center of Silicon Valley - Dr. Gary Kawesch

20/20 vision is a term developed by optometrists and ophthalmologists to determine what a “normal” person can see when they are 20 feet from an object. Many people who do not have 20/20 vision require glasses or contacts to assist them in seeing more normally. We perform LASIK surgery at our San Francisco, California to improve people’s vision so they no longer require contacts or glasses.

If you have 20/20 vision, when you stand 20 feet from an eye chart, you can see what most other people can see. However, if you are near or far sighted, you may have 20/40 or 20/100 vision, which means when you stand 20 feet away from the chart, you see the same detail that a normal person would see 40 or 100 feet from the chart.

Much of what determines how well you can see involves the shape of the eyeball. When light enters the eye, it passes through the pupil to the retina in the back of the eye. If your eyes are too steep or too elongated, it can cause the light to focus improperly.

During LASIK, a laser is used to reshape the corneal tissue, and allow light to hit the retina properly, providing you with improved vision. LASIK can correct nearly any prescription, and will almost always improve vision enough for you to pass a driving test without glasses or contacts.

If you would like to learn more about your vision and whether LASIK can improve what you see, please contact us at the Laser Eye Center of Silicon Valley today to schedule your initial LASIK consultation.
