Eye exams are recommended periodically, with the interval differing for various age groups.  In the first three years of infancy, a child should have vision checked along with normal pediatric checkups.  Between the ages of three and six (the most crucial period of eye development) an eye exam should be scheduled every year or two.  After that period, until adulthood, exams should be scheduled as necessary.  During the twenties one should have at least one exam.  During the thirties one should have at least two exams.  In the forties, fifties, and early sixties, one should schedule an exam every two to four years.  For seniors, an exam every year or two is recommended.

In addition to these basic guidelines, people with a family history of eye problems, those monitoring a diagnosed eye disease, or those with certain high risk diseases such as diabetes, it is recommended that exams should be performed at least once a year.  Regular eye exams are the best way to keep you seeing your world clearly.

Any abnormal phenomena or changes in your vision can indicate a variety of possible problems.  The key to preserving vision in the face of most eye diseases is early treatment.  Thus it is important to consult an ophthalmologist if you notice anything unusual or any change in your vision.  It could be a serious problem, or it could be inconsequential, but the peace of mind and the possibility of catching a serious problem early are certainly worth it.

Many serious eye diseases often have little or no symptoms until they are well developed.  The only way to diagnose a problem early in such a case is to schedule periodic eye exams.  This is the best way to preserve the clearest vision possible for life.

A cataract is a clouding of the normally clear lens of your eye.  For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged up window.  They are one of the leading causes of vision impairment in the United States.  However, because cataracts form slowly and over a long period of time, many people suffer from them without ever realizing it.  You may have cataracts if you experience one or more of these symptoms: 

  • Blurry or foggy vision
  • Colors appear dull or washed out
  • Poor night vision
  • Halos appear around lights
  • Sensitivity to sunlight or bright lights
  • Needing more light to read
  • Your glasses don’t seem to work


Initially, stronger lighting and eyeglasses can help with cataracts.  But, if impaired vision interferes with your usual activities, you might need cataract surgery.  Fortunately, cataract surgery is generally a safe and effective procedure that involves removing the clouded lens and replacing it with a clear artificial lens.  Cataract surgery is generally done on an outpatient basis, using local anesthesia to numb the area around the eye.  You may experience improved vision very soon after surgery, but your sight will continue to steadily improve.  You generally will be healed within eight weeks after surgery.
