App Description
"LEA ACUITY" is a unique interactive chart to measure visual acuity specifically in PRESCHOOL children! CHECK ALSO THE ADVANCED VERSIONS "FAST ACUITY" or "VISUAL ACUITY"!
Important Notice: this app is for iPhone and iPod touch ONLY, and should NOT be run on the iPad because of the different display resolution!
To get the best results with "LEA ACUITY" make sure to follow these simple steps:
1) set precisely the viewing distance of the patient using the bottom slider,
2) adjust the vertical slider on the right to select a range of letter sizes that can be easily seen by the patient,
3) press the + and - buttons to fine tune the letters size by small steps,
4) touch the smallest line the patient can fully read.
Et voila! The visual acuity is reported with some useful comments (Tip: tap on the acuity line above the chart to produce a new random chart).
NOTE that, contrarily to other acuity charts available on the iPhone, all our charts:
- are randomly generated to prevent memory effects,
- support distance up to 8 meters (26 ft),
- support metric or imperial units for distance or acuity,
- provide a unique interactivity for maximum flexibility (and support device rotation),
- and most importantly, they follow the logMAR design recommended by the NATIONAL EYE INSTITUTE and the INTERNATIONAL COUNCIL OF OPHTHALMOLOGY.
CHECK OUT the full version "FAST ACUITY" that includes additional charts specifically designed for testing literate people (Sloan chart) and preschool children (HOTV chart)!
