I see fine, why do I need to see an Eye Doctor?

Regular eye exams are the only way to catch "silent" diseases such as diabetes, glaucoma and other conditions in their early stages, when they're more easily managed or treated. Many conditions can be discovered in a carefully planned eye exam. Those who consider mass-produced, over the counter reading glasses are truly doing themselves a disservice, both financially and medically.

OOne-size-fits-all reading glasses not only do not work well for most people who have a different prescription in each eye, and/or astigmatism, or whose lens and frame parameters are not measured correctly, they bypass the opportunity to have their eyes checked for early detection of many manageable diseases or conditions. For those insisting on selecting glasses not measured specifically for there eyes, headaches and eye fatigue are common symptoms.

How often should I get a new pair of glasses?

This is a personal concern that can address many issues. You should change your eyeglasses when you feel that your existing eyeglasses no longer are supporting your needs, lifestyle, or taste.

In any case a visit to your doctor should not be only considered when you feel it is time for new glasses. You should visit your eye doctor at least once every year, unless otherwise instructed by your eyecare provider.

What is LASEK?

LASEK takes the best of both PRK and LASIK. As in PRK, there is no microkeratome used during the LASEK procedure and the surface cells are replaced, like LASIK, for quicker visual recovery. However since only the epithelial cells (the outer most layer of cornea) are used in making the LASEK flap, there is no permanent corneal flap.

What is a Cataract?

A cataract is the clouding of the crystalline lens in your eye. This opacity obstructs the passage of light resulting in a reduction of clear vision. Normally, light passes through the clear lens and is focused onto the Retina. However, the natural aging process can cause the lens to become cloudy, or milky. The cataract blocks the passage of light through the eye and causes distorted or blurred vision, glare, or difficulty seeing in poor lighting conditions.

There are three types of cataracts:

A nuclear cataract forms in the lens. Those over 65 are more prone to develop this type of cataract. More than half of all Americans over the age of 65 will develop a cataract.

A cortical cataract forms in the lens, then grows from the outside to the center of the lens. Diabetics are more prone to develop this type of cataract.

A subcapsular cataract forms in the back of the lens. Those with diabetes, high hyperopia (Far-sightedness) or retinitis pigmentosa may be at a higher risk to develop this type of cataract.
