Despite the explosion in HDTV sales driven by a desire to watch every second of those vital matches, it would seem many people are wasting both their time and money. It really doesn't matter how sharp the image on your TV if the lens in your own eyes give a blurred effect.

With fans attracted by the prospect of improved picture quality, clarity and definition, it is estimated (by Kelco) that the World Cup will help to boost sales of HD TVs by 5% to a total of 7.6 million sets sold in this year alone. However a survey by Glasses Direct, the world's largest online prescription eyewear store, found that 35% of the UK's 32 million glasses wearers have not bought a new pair of prescription glasses in the last two years. They may be unaware that their potentially reduced vision will impede their viewing of the beautiful game which would be a real shame, as three million people have now subscribed to HD in the UK.

"Even a slightly short sighted person trying to watch an England match on HD TV may fail to take advantage of the superior picture quality. If you're investing the money to buy an HD TV to watch the World Cup, you ought to have your eyes checked to ensure you're experiencing the full benefit" says David Hutchfield, Dispensing Optician at Glasses Direct.

Jamie Murray Wells, Founder and Executive Chairman of Glasses Direct adds "We want to help the fans get as much out of the World Cup as possible so we're giving away a free pair of Fabio Capello style ZeroRH+ frames complete with prescription lenses to the first hundred people who now get their eyes tested and find they need a new pair of prescription glasses."
