Wearing face coverings to protect oneself from coronavirus can trigger a new medical phenomenon nicknamed 'mask eye', optometrists have warned. They have issued advice on how to cope with face-covering-associated ocular irritation. More than one in five people are struggling to maintain healthy eyes while wearing face coverings to reduce the spread of coronavirus, according to research by the College of Optometrists to mark National Eye Health Week. People in the UK are legally obliged to wear a face covering in settings such as public transport, shops and supermarkets, entertainment venues and places of worship, according to the Government's website. Daniel Hardiman-McCartney, clinical adviser to the College of Optometrists, said: "As you breathe out, air is directed out of the top of your mask and is blown over the surface of your eye. "This may result in your tears becoming disrupted and evaporating more quickly which can cause discomfort and a gritty feeling where your eyes may become watery and look red or sore." He said people experiencing eye discomfort should first ensure their mask fits firmly around their nose, so air is forced out at the sides. Lubricating drops or sprays can also be used to help keep the eye surface moist. Mr Hardiman-McCartney said: "We know from our own research that 22 per cent of people noticed their vision deteriorate during lockdown, so we are urging these people and anyone who is having issues with their eyes to contact their local optometrist. "All practices will be following Government guidance and optometrists wearing PPE, to ensure that your visit is safe." Blinking three or four times and shutting your eyes tightly for a few seconds every 20 minutes can also help naturally refresh the eyes.
