Amblyopia (lazy eye) is the most common cause of vision impairment in one eye in children – 1 or 2 in every classroom – and can impact reading speed and fine motor skills in some affected children. Early detection and treatment is crucial for obtaining the best vision outcomes. Krista Kelly, Ph.D., Postdoctoral Fellow, Crystal Charity Ball Pediatric Vision Lab, suggests following vision screening recommendations of the American Association for Pediatric Ophthalmology and Strabismus. Routine vision screening should begin before a child starts school, and can be done as part of well-child visits. Screening involves reading a chart with letters or pictures, or using a device called a photoscreener to check for risk factors affecting vision, such as amblyopia, strabismus (misalignment of the eyes), a need for glasses, or other conditions. Vision screening is typically performed by pediatricians, school nurses, and other healthcare professionals and volunteers. Children who fail vision screening will be referred for a more comprehensive eye exam by an eye-care professional.
