20/20 Eyesight is Not Enough
Why is it important to get an Eye Exam done when your child has already had a Vision Screening?

Vision screenings can uncover some vision problems, but they can miss more than they find. This is a major concern about vision screening programs. Current vision screening methods cannot be relied on to effectively identify individuals who need vision care. In some cases, vision screening may actually inhibit the early diagnosis of vision problems. Screenings can create a false sense of security for those individuals who “pass” the screening but who actually have a vision problem. These people are then less likely to receive treatment for their vision problem and it could become worse.

What are the limitations of vision screening programs?
Limited testing

Many vision screenings test only for distance visual acuity. While the ability to see clearly in the distance is important, it does not indicate how well the eyes focus up close or work together. It also does not give any information about the health of the eyes.Some screenings may also include a plus lens test for farsightedness and a test of eye coordination. However, even these additional screening tests will miss many vision problems.

Untrained personnel

Often, administrative personnel or volunteers who have little training conduct a vision screening. While well-intentioned, these individuals do not have the knowledge to competently assess screening results.

Inadequate testing equipment

Even when done in a pediatrician’s or primary care physician’s office, the scope of vision screening may be limited by the type of testing equipment available. Factors such as room lighting, testing distances and maintenance of the testing equipment can also affect test results.
