AOC includes more than 60 dynamic, interactive tests, grouped in 5 main programs: Visual Acuity, Refraction, Contrast Sensitivity, Binocular and Driver’s License.
LIST OF TESTS
VISUAL ACUITY
Sloan Letters, Landolt Rings (ISO 8596), Tumbling E, Numbers, Snellen Letters, HOTV, Pigassou Child Symbols, Core Child Symbols, Playstation, Allen Preschool, Sloan Non Random Letters, Landolt C 4 symbols.
ETDRS
Tables 1, 2, R with contrast function. Three view modes: standard, IOL and mesopic. Illiterate mode and masking function.
REFRACTION
Myopia (Red and Green), Clock Dial, Points, Half clock, Astigmatism – Fan and Block, Grid test, Binocular Balance, Amsler’s Grid.
CONTRAST SENSITIVITY
Small Letter Contrast test, Pelli-Robson @1m, Contrast Sensitivity – Gabor patches, Ishihara color blindness test. All the optotype charts have a contrast function at 0.15 Log steps.
BINOCULAR VISION
Points of Fix, Maddox, Worth, Schober test, Sheard test, Phoria & Associated Phoria tests, Aniseikonia, OXO – Mallet test, Random dots Steps/Hand, Osterberg Stereo 2/4, Duochrome, Pictures for Retinoscopy.
MKH
Cross test, Pointer test, Rectangle test, Stereo Triangle, Balance test, Differential D6/D8 stereo test, Stereo test, Cowen test.
DRIVER’S LICENSE EXAM
Visual Acuity OD/OS, Contrast Sensitivity, Twilight Vision (mesopic visual acuity), Glare Sensitivity, Glare Recovery Time.

OPTIONS
Professionals can put together the examination program by creating sequences of preferred tests.
All optotype tests support different display modes and options.
There is also a “memory function” that lets you switch between visual acuity tests while maintaining the parameters of the current optotype chart.
Child (or Illiterate) and Low Vision modes streamline clinical use.
