Fast Acuity Lite 1.0

Fastest and most reliable VISUAL ACUITY TEST for the general population!

Check out the full version: "FAST ACUITY", the best visual acuity test for literate & illiterate people as well as preschool children!

Forget all these eye tests based on the 150 year-old Snellen chart:

1) FAST ACUITY LITE presents an interactive eye chart that follows the recommendations by the NATIONAL EYE INSTITUTE and the INTERNATIONAL COUNCIL OF OPHTHALMOLOGY to address design flaws in the Snellen chart.

2) FAST ACUITY LITE uses Landolt C and Tumbling E symbols considered as the reference optotypes for testing visual acuity by the International Council of Ophthalmology in its VISUAL ACUITY MEASUREMENT STANDARD.

3) FAST ACUITY LITE can produce an infinite number of eye charts (tap on the acuity line above the chart to produce a new random chart).

FAST ACUITY LITE could not be easier to use:

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 in term of the orientation of each letter,

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.

Several options are available to customize the test: choice of C or E optotypes, foot or meter acuity units, choice of 4 or 8 orientations, choice between black letter on white background or vice versa.

Note that only the C and E optotypes are available in this lite version. The full version "FAST ACUITY" includes additional charts: the Sloan, HOVT and Lea charts. All of these interactive charts will soon be included in version 1.3 of our full featured iPhone app "VISUAL ACUITY" (the Landolt C & Tumbling E charts have already been added in the current version).
