Think You Need New Glasses? You Actually Might Have Cataracts

Posted in Family Health.

Many seniors think that new glasses and a stronger prescription is all they need to get back the vision of their youth. The fact is that cataracts may be the cause for the decline in vision. The condition is the leading cause of vision loss among adults 55 and older. In fact, more than half the people over age 65 have some degree of cataract development. 

Moreover, a recent study out of the University of Texas Medical Branch in Galveston indicates that seniors suffering from poor vision have shown evidence of a premature mental decline. The results of this study clearly bring to light the importance of routine eye care for older adults, who are at increased risk of eye conditions that cause severe visual impairment such as cataracts. 

 

What is a cataract?

 

 A cataract is a clouding of the lens in the eye, the part of the eye that focuses light and produces clear images on the back of the eye called the retina. Inside of the eye, the lens is contained in a sealed bag or capsule. As old cells die they become trapped within the capsule. Over time, more cells die and accumulate causing the lens to cloud, making images look blurred or fuzzy. For most people, cataracts are a natural result of aging.

 

 

 What are common symptoms of cataract?

  • a painless blurring of vision
  • light sensitivity
  • poor night vision
  • double vision in one eye
  • needing a brighter light to read
  • colors looking faded or yellow

How is cataract treated?

In the early stages, stronger lighting and eyeglasses may lessen vision problems caused by cataracts. At a certain point, however, surgery to remove the cataract may be needed to improve your vision and general lifestyle.  Usually, a lens implant is placed at the time of surgery to replace the natural lens. Cataract surgery is the most frequently performed surgery in the United States. More than 90% of the people who have cataract surgery regain useful vision.  Your ophthalmologist will explain your alternatives, risks, and benefits at the appropriate time.

Am I at risk for cataract?

The most common type of cataract is related to aging. In an age-related cataract, the center of the lens gradually hardens and becomes cloudy. It may become so cloudy that your Eye M.D. cannot clearly see the details of the retina. At that point, you might experience difficulty identifying colors and seeing at a distance.

Other causes of cataract include:

 

  • family history of cataracts
  • medical problems, like diabetes
  • injury to the eye
  • medications, especially steroids
  • radiation
  • long-term, unprotected exposure to sunlight
  • previous eye surgery
  • smoking
 

 

 

 

 

 

By performing a thorough eye exam, your ophthalmologist can detect the presence of a cataract.  To learn more about cataract, visit www.eyecareamerica.org.
