Free children's vision screening program for senior kindergarten (SK) students
  • Vision screening looks for signs of potential vision problems in children
  • School-based vision screening allows for all children to be checked for signs of eye problems so they can be treated in a timely manner (children who already wear glasses will be screened with their glasses on)
  • Three short, non-invasive tests will test for vision problems commonly found in children:
    • Autorefractor: the student's eyes will be scanned with a camera to measure the size and shape of the eyes
    • HOTV Visual Acuity Chart: the student will be asked to identify letters on a chart to measure clarity or sharpness of vision
    • Randot 3D Vision Test: the student will be asked to identify or point to shapes while wearing 3D glasses to measure depth perception
Note: Vision screening cannot detect all vision problems, and does not replace a child's regular visits to an optometrist
