Corneal Conditions

The cornea, the part of the eye on which contacts are worn, is a transparent surface where the light passes through and imprints an image on the retina. The light passing through creates a chemically and electronically induced reaction that travels through optic nerves to the brain allowing us to see.

The cornea is normally clear because it does not have blood vessels and has a shiny surface. It must be completely transparent for us to see clearly and is extremely sensitive to light because it has more nerve endings in the body than anywhere else.

Diabetic Eye Care

If you are diabetic, there is something you should know about your eyes. Diabetic retinopathy is an eye disease that can affect the retina and cause a loss of vision if not diagnosed and treated early. Tiny red dots, known as microaneurysms, are small retinal hemorrhages that develop in the eye, and can cause a lack of blood flow. When the eye is lacking blood flow, blood vessels can form in the wrong places in the eye and cause scaring and tearing of the retina, and this can result in vision problems.

What is Red Eye?

Eye redness is due to swollen or dilated blood vessels, which cause the surface of the eye to look red, or bloodshot. There are many possible causes of a red eye or eyes. Some are cause for concern; some are medical emergencies. Others are nothing to worry about. How red the eye appears is often less of a concern than whether you also have eye pain or difficulty seeing.

Computer Use Guidelines After LASIK

People rely on their eyes on a day-to-day basis to complete their most basic daily tasks. For the majority of people, the computer is just as much a part of those daily rituals. Many people spend up to 40 hours a week in front of a computer screen at work, and that doesn’t take into account the time that is spent on tablets and smartphones. LASIK corrects the most common forms of vision impairment to allow patients to see clearly without relying on glasses or contact lenses. But most people have heard that computer use should be limited after LASIK surgery. Dr. Stanley Teplick of Teplick Custom Vision, an NVISION Company, discusses LASIK and computer use with his Portland, OR patients, and offers them some reasonable guidelines to ensure that the eyes stay protected following LASIK treatment.
