Worried that your kids will end up with poor eyesight by sitting too close to the TV? Well, now take a sigh of relief for a new super-smart TV will turn its picture fuzzy if it senses a youngster is too near to the screen. And it won’t go back to normal until the child moves away to a safe distance. The LX 3D model from Sony hits the shops in the UK next month. The TV set uses a type of face- recognition technology to distinguish children from adults and can work out how far they are from the set and whether they risk damage to their eyes.

The LX, which has not yet been given a price, was unveiled as part of Sony’s latest range of 3D TVs. The first will go on sale, starting with the 3D-capable HX8 40in, priced around 1,800 pounds, and the HX8 46in at around 2,200 pounds.
