4.2.2. Usage with limited vision

Where <abbr title="Information and Communication Technologies">ICT</abbr> provides visual modes of operation, some users will need the ICT to provide features that enable users to make better use of their limited vision.


  1. Magnification, reduction of required field of vision and control of contrast may contribute towards meeting this clause.
  2. Where significant features of the user interface are dependent on depth perception, the provision of additional methods of distinguishing between the features may contribute towards meeting this clause.
  3. Users with limited vision may also benefit from non-visual access (see clause 4.2.1).

There is currently no content classified with this term.

Components that implement this clause

This is the prototype for ChromaFocus LITE, a next-generation color-picker for contrast and colorblindness, which is now moved to a new repo (sorry for inconveniences). It will be periodically updated to reflect ChromaFocus LITE's codebase. ChromaFocus PRO (due in mid 2018) will not be posted at this location.
