Guide Dogs is highlighting its role in preventing blindness and visual impairment with its second annual One Vision eye care awareness week, launched tomorrow.
Baroness Betty Boothroyd will test her eyes on a new computerised vision screener, which will be offered free to companies throughout July in a bid to improve the eye health of the UK's six million VDU computer users.
Eye Kon, a screen saver that reminds people to take a screen break, is downloadable from the charity's web site.
Guide Dogs has been stepping up publicity about its eye care work over the past two years. While the provision and training of guide dogs remains its core focus, the charity has been funding eye care research since 1990 and is also involved in providing other mobility aids for blind and partially sighted people.
A spokeswoman said: "We were doing this eye care work but we weren't telling anyone about it until last summer when we launched One Vision for the first time. People in time will recognise that although guide dogs is our major activity, there is more to us than that and that we are in the business of eye care too.
