WHEN Tom Davies, the spectacles designer, asked his opticians in London to survey how many customers suffered from dry eyes the results were astonishing. “More than 60 per cent, with many saying it was the bane of their lives.”
It reinforced what he’d spotted on a trip to the US, where dry eye clinics were everywhere. “It’s the epidemic that no one is talking about,” says Davies. “People are staring at screens for hours, at blue light and not blinking enough; they’re exposed to pollution; and well into old age. Their tear ducts are getting blocked. They can no longer form proper tears.”
