Limitations Of Vision Screening Programs
Vision screening programs are intended to identify children or adults who may have undetected vision problems. If the screening indicates a vision problem, they are referred for further evaluation.
However, a vision screening can’t be relied on to provide the same results as aâ¯comprehensive eye and vision examination.
Screenings can take many forms. Often schools provide periodic vision screenings for their students. A pediatrician or other primary care physician may do a vision screening as part of a school physical. When applying for a driver’s license, your vision will likely be screened. Vision screenings are often part of local health fairs put on by hospitals, social service agencies or fraternal groups like the Lions and Elks clubs.
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.

How Is A Comprehensive Eye Examination Different From A Vision Screening
Specialized equipment and procedures, which are not available as part of a vision screening program, are needed to adequately evaluate eyes and vision.
Only a doctor of optometry or ophthalmologist can conduct a comprehensive eye and vision examination. These doctors have the specialized training necessary to make a definitive diagnosis and prescribe treatment.
A comprehensive adult eye examination includes:
- Patient and family health history.
- Visual acuity measurement.
- Preliminary tests of visual function and eye health, including depth perception, color vision, peripheral vision and the response of the pupils to light.
- Assessment of refractive status to determine the presence of nearsightedness, farsightedness or astigmatism.
- Evaluation of eye focusing, eye teaming and eye movement abilities.
- Eye health examination.
- Additional tests as needed.
Vision screening programs can’t substitute for regular professional vision care. Children or adults who pass a vision screening could still have an eye health or vision problem. Comprehensive eye examinations are the only effective way to confirm or rule out any eye disease or vision problem.

For a few hours after an eye dilation, you should avoid driving, reading and looking at screens. Make sure to wear sunglasses to protect your eyes from the sun as your pupils shrink back to normal.
