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.

Notes:

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).
