Vision Testing Apparatus & Method

A method of testing vision, the method comprising:

• obtaining data characterising the performance characteristics of a local display;
• adapting a reference vision test in accordance with said characterising data to generate an adapted vision test that is a faithful reproduction of said reference test when displayed on said local display;
• displaying said adapted vision test to a user at said local display;
• registering user input in response to said displayed adapted vision test;
• generating a set of results based on said registered user input;
• and
• providing said results to the user.

A vision testing system comprising a vision test web-server and a local vision testing apparatus that can each communicate one with the other via an internet, wherein:

• the local vision testing apparatus comprises:
• a local display;
• means for obtaining data characterising the performance characteristics of said local display;
• means for displaying to a user at said local display, a vision test that comprises an adaptation of a reference vision test;
• means for registering user input in response to said displayed vision test;
• means for providing the user with the results of said displayed test;
• and a communications interface for web-based communications with said web-server;
• the vision test web-server comprises:
• a store for reference vision tests;
• means for adapting a selected vision test with data characterising the local display of said vision test apparatus;
• means for sending said adapted vision test to said local vision testing apparatus for display to a user;
• means for generating a set of results based on registered user input received from said local vision testing apparatus;
• and means for sending said results to said local vision testing apparatus.
