Research fellow Dr Nisha Yeotikar said: ‘Our eyes water for many reasons. An eye irritation may result in protective watering that can clear irritants - fumes from onions or an allergic reaction, for example.’
The research led by Dr Yeotikar found that as we get older, eye lubrication from the meibomian gland decreases, but found that tears could make up for a loss of lubrication caused by MGD.
