ÖNORM EN ISO 9241-303

This part of the standard establishes image quality requirements for electronic visual displays. The requirements are generic, independent of technology, task and environment. They are stated as performance specifications to ensure effective and comfortable viewing conditions for users with normal or adjusted to normal eyesight. This standard does not address issues of accessibility for people with disabilities. It does take into account aspects of the eyesight of older people. This standard, however, may be of value to people dealing with issues of visual impairment in certain cases; the specification of essential characteristics for normal viewing can be used to gauge the severity of different visual abnormalities so that appropriate solutions may be identified. Moreover, a selection of the relevant documents regarding the needs of people with disabilities including those who have poor, deteriorating or no sight appears in the informative Annex E. 20.
