Portable tablet games effectively assess chromatic contrast sensitivity in normally sighted individuals. These vision tests show good repeatability, offering a promising tool for clinical use and early disease detection.

Area of Science:

  • Ophthalmology
  • Vision Science
  • Human-Computer Interaction

Background:

  • Tablet computer displays offer a portable platform for developing vision tests.
  • Assessing color vision with accessible, portable tests aids self-monitoring and early disease detection.
  • Gamified tablet applications can assess chromatic contrast sensitivity, providing a portable alternative to traditional methods.

Purpose of the Study:

  • To determine normative values for tablet computer-based chromatic contrast sensitivity games.
  • To evaluate the repeatability of these games compared to the Cambridge Colour Test (CCT).
  • To assess the potential of gamified vision tests for clinical application.

Main Methods:

  • Developed three tablet-based games with varying gamification levels to assess chromatic contrast sensitivity.

  • Compared the performance of these games against the Cambridge Colour Test (CCT) Trivector test.
  • Evaluated chromatic contrast sensitivity in 100 normally sighted individuals (median age 19.0 years).

    • Main Results:

    • Games 1 and 2, along with the CCT, demonstrated similar absolute thresholds and tolerance intervals.
    • Game 3 showed significantly lower values than Games 1, 2, and CCT due to task differences.
    • Repeatability was comparable across the CCT and tablet games, except for game 3 (blue-yellow).

    Conclusions:

    • Custom-designed tablet games are portable and rapid for assessing chromatic contrast sensitivity.
    • These games show good repeatability and may be suitable for routine clinical practice.
    • The developed games are particularly promising for testing younger populations.
