To be able to appreciate the benefits of Blu-ray and HDTV, you need to have perfect "20/20" vision, experts say--and up to a third of people in Britain don"t. This means that millions of pounds spent on high-definition televisions and Blu-ray equipment are effectively being wasted.
The fact is that most people do not have their eyes examined regularly, and the result is that up to a third of UK residents have less than perfect vision--most without even knowing it. This is true even if they do have glasses or contact lenses, for many go too long between check-ups and don"t notice that their prescriptions are no longer up to scratch.
This leads to many consumers paying out for equipment and Blu-ray discs when they can"t enjoy the superior resolution and colour offered by the technologies.
What can be done? According to Vision Express optician Phillip Hyde, "[a] small change in prescription can potentially make a big change in the quality of the picture that you see. If you"re investing in HDTV, you ought to have your eyes checked to make sure you get the full benefit."
