How can technology be used in vision screening programs?
A. The vision screeners (examples below) are appropriate for vision screening. However, caution needs to be exercised when using the equipment with young children as they have been able to peak on the older equipment as a result of the equipment’s ergonomics. The older equipment is not designed to accommodate the small head of young child to the viewer. MDH also recommends testing color vision separately, as the manual color vision books have higher sensitivity. The visual acuity referral criteria are the same as for the vision charts (20/40 for age 4 and under, 20/30 for age 5 and older). Pictured below are the Titmus and Keystone screeners as examples. Other brands are also available. The price range is $1,400.00-$1,700.00.
