Survey respondents report using a variety of methods to notify parents of the results of their child's visual screening. Some respondents report using more than one method. Knowing the outcome of the referral for a professional eye examination is critical to the success of a vision screening program. Five percent of the schools screen for distance vision only if a student has a vision concern, not at any specific grade level. Table 2 below shows the instruments used for distance vision screening by the respondents.
Some respondents report using a combination of instruments.
A variety of other screening charts are used by respondents. Survey results indicate the Titmus Vision Screener is the most frequently used machine for distance vision. The vision survey committee expressed concern that the Titmus Vision Screener may be obsolete. The model of Titmus Vision Screener used in most cases is not known. Models made before 1984 have been discontinued and parts are no longer available.
