STEPS

The following Vizavance screening components are part of a minimum or baseline for effective children’s vision screening and are state mandated:

Explanation of our Vision Screening Process

Distance Visual Acuity Screening

Visual acuity is defined as sharpness of vision; the standard measurement is 20/20. Distance visual acuity is typically determined by having a person “read” an eye chart at a standardized distance. In Oklahoma, all PK and Kindergarten students are screened down to the 20/30 line. A passing score for PK and Kindergarten is 20/40 or better in both eyes. Students in 1st grade and older are screened down to the 20/30 line. A passing score for 1st grade and older is 20/30 in both eyes.

Random Dot E Stereopsis Test (RDE)

Stereopsis is the visual perception of three-dimensional space resulting from the blending of the images in each eye. Stereopsis testing is conducted to determine if the eyes are working together.

Near Vision Test

This is a specialized test administered to 4th graders and up to determine if a child is having difficulty viewing objects at close range. With both eyes uncovered the student is asked to read the letters on the 20/30 or 20/32 line.

SPOT Vision Screener Camera

The Spot Vision Screener is a handheld vision screening device that quickly and easily detect vision issues on children from 6 months of age through adult. Spot screens both eyes at once from a nonthreatening 3-foot distance. Spot accurately detects the potential indication of these common vision problems:

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Astigmatism (blurred vision)
  • Anisometropia (unequal refractive power)
  • Strabismus (eye misalignment)
  • Anisocoria (unequal pupil size)

Testing for Color Vision

Color Vision Defect – Pseudoisochromatic Plate (PIP) Test – Also known as “Color Blindness,” a genetic color vision defect: Red/Green, Blue/Yellow. This genetic defect will not change over time and is usually symmetrical. Vizavance screens the Pre-K and Kindergartener children in schools.

Referral Letter

Vizavance provides referral letters to children and adults who do not pass the vision screenings and need a comprehensive eye exam.

Seemore Screening Form

All students receive a Seemore Screening Form, informing the parents/ guardians the results of the Vizavance vision screening that day.
