Vision Screenings Q & A

What is a vision screening?

A vision screening is a type of eye exam that uses simple, quick testing to identify potential vision problems. Unlike a comprehensive exam, a vision screening does not use dilating eye drops to see into the rear portion of the eye; instead, it uses a series of assessments to evaluate how well a person sees under different circumstances and at different distances.

Vision screening is especially important in identifying possible vision problems in older adults, very young children, and in school-age children, including problems that can interfere with schoolwork, socialization, sports, and other activities. If a vision problem is identified during a vision screening, in most cases, the patient will receive a comprehensive eye exam to determine the underlying cause of the problem.

When should children have vision screenings?

Vision screenings play a critical role in childhood eye development. When vision problems are uncorrected in a child’s younger years, the brain doesn’t learn how to “translate” image data, and that can have a long-term effect on the child’s development and even their adult life.

The American Academy of Ophthalmology and the American Association for Pediatric Ophthalmology and Strabismus recommend screenings before 12 months of age, at three years of age, and when entering school, with periodic vision screening performed whenever a problem is suspected. Additional screenings should be performed throughout childhood to look for signs of vision problems, including myopia (nearsightedness), which is especially prevalent among children.

What kinds of vision problems can be detected with a vision screening?

Vision screening is highly effective in identifying children and adults who have or are at risk for vision problems like:

  • Myopia or astigmatism
  • Amblyopia (a condition that develops when the brain “favors” one eye over the other, causing the “non-favored” eye to become weak)
  • Strabismus (misalignment of the eyes)
  • Ptosis (lid drooping)
  • Cataracts
  • Glaucoma
  • Neurological issues or tumors

Our doctors and staff are committed to ensuring all children receive appropriate vision screening, and we offer free vision screenings for all school-age children.

What happens during a vision screening?

The tests performed during a vision screening depend in part on the child’s age. Most vision exams begin with an assessment of the eye and the pupils and an evaluation of the “red reflex,” a reflection of light from the pupil that’s normally bright red and of equal brightness in each eye. Other tests assess the alignment of the eyes and the health of the cornea. Preschoolers and older children will undergo an eye chart test to help identify refractive vision problems like myopia, hyperopia, and astigmatism.
