Vision Problems Often Result From Refractive Errors

Background

More than 11 million Americans have common vision problems that can be corrected with the use of prescriptive eyewear such as glasses or contact lenses or surgically with Lasik or Cataract surgery. These conditions are known as refractive errors and they occur when the eye doesn’t correctly bend, or refract, light as it enters the eye. Common refractive errors include the following:

Nearsightedness (also called myopia)—A condition where objects up close appear clearly, while objects far away appear blurry. With nearsightedness, light comes to focus in front of the retina instead of on the retina.

Farsightedness (also called hyperopia)—a common type of refractive error where distant objects may be seen more clearly than objects that are near. However, people experience farsightedness differently. Some people may not notice any problems with their vision, especially when they are young. For people

with significant farsightedness, vision can be blurry for objects at any distance, near or far.

Astigmatism—A condition in which the eye does not focus light evenly onto the retina, the light-sensitive tissue at the back of the eye. This can cause images to appear blurry and stretched out.

Presbyopia—an age-related condition in which the ability to focus up close becomes more difficult. As the eye ages, the lens can no longer change shape enough to allow the eye to focus close objects clearly.

Refractive errors are one of the most common and correctable causes of visual impairment in the United States. According to a recent study led by the National Eye Institute (NEI), approximately half of all American adults don’t have the 20/20 vision physicians consider optimal due to refractive errors.

Correction for refractive errors is relatively simple and includes eyeglasses, contact lenses and refractive surgeries such as Lasik.. Technological advances have improved visual outcomes following refractive surgery. Not that long ago cataract surgeries involved large incisions and the need for thick glasses post-operatively to maintain good vision. Today cataract surgery has evolved to where there is minimal anesthesia, no need for stitches and with our newer implants markedly reduced need for glasses post-operatively. Technology has now made it possible to achieve excellent vision both at distance and near without needing glasses at all. At SightMD we offer all the most common forms of refractive surgery. Our cataract and refractive surgeons are among the best and continually achieve excellent results. Call today to schedule an appointment to be evaluated for refractive surgery or cataract extraction.SightMD has many locations with evening and weekend hours to serve you.
