Note: This app is designed only for iPads with high resolution retina displays. It will not display near vision optotypes correctly on iPads without the retina display.

Finally . . . you can now screen and test vision with evidence-based eye charts and optotypes on any iPad with retina display.

The School Health Near/Distance Vision Screening and Testing app by Good-Lite for any iPad with retina display features evidence-based, proportionally spaced eye chart designs and optotypes for screening and testing both distance and near vision. App also includes Continuous Reading Text.

Charts adhere to national and international guidelines for eye chart design.

Near and distance vision threshold charts include LEA Symbols, HOTV, LEA Numbers, and Sloan Letters. Toggle button provides ability to change charts to prevent memorization. Each eye chart and Continuous Reading Text chart has 3 charts choices.

LEA Symbols and HOTV charts include a screen with the 4 individual optotypes that individuals can identify before starting the screen/test.

App settings permit screening or testing at different distances and measurements.
Choices for distance vision optotype notations are: 10 foot actual, 20 foot equivalent, 3 meter actual, 6 meter equivalent, letter size (M size), decimal, and logMAR.

For example, the screening/testing distance for distance vision charts used at the 20 foot equivalent setting would be 10 feet/3 meters with results equivalent to 20 feet (i.e., 10/10 would be reported as 20/20). Line sizes range in this setting from 20/16 to 20/63 and include 20/16, 20/20, 20/25, 20/32, 20/40, 20/50, and 20/63.

Choices for near and reading optotype notations are: 20 foot equivalent, 6 meter equivalent, letter size (M size), decimal, logMAR, and diopters of add for 1 meter

For example, the screening/testing distance for near vision charts used at the 20 foot equivalent setting would be 16 inches/40 centimeters with results equivalent to 20 feet. Line sizes range in this setting from 20/16 to 20/320 and include 20/16, 20/20, 20/25, 20/32, 20/40, 20/50, 20/63, 20/80, 20/100, 20/125, 20/160, 20/200, 20/250, and 20/320.

The Continuous Text Reading chart includes 4 to 13 short sentences for each line size in the 20 foot equivalent setting. Chart line sizes in this setting range from 20/20 to 20/80 and include 20/20, 20/25, 20/32, 20/40, 20/50, 20/63, and 20/80.
