How would you view a man who's stockpiled a lifetime supply of old-fashioned light bulbs because he believes low-energy bulbs could lead to blindness?
You might well dismiss him as dotty. But the man in question, John Marshall, is no crank. In fact, he's one of Britain's most eminent eye experts, the professor of ophthalmology at the University College London Institute of Ophthalmology. So concerned is he that he has boxes stacked with old-fashioned incandescent lightbulbs at home.
'I bulk bought incandescent lightbulbs before the Government made it illegal to import them,' he says.

Nor is he alone in his concerns about modern light bulbs. Another eminent British professor, John Hawk, an expert in skin disease, is warning they may cause sunburn-like damage, premature aging and even skin cancer.
He doesn't have any low-energy bulbs in his house, explaining: 'I have lots of old-style bulbs I bought in bulk when they were available.'
Incandescent bulbs had been the standard form of illumination for more than a century. But following an EU directive, the Government banned the import of 100-watt bulbs from 2009. This was followed by a ban on 60w bulbs in 2011 and a full ban on all 'traditional' bulbs in 2012.
