Eye infections often lead to blepharitis, which is an inflammation of the eyelids that leaves them feeling itchy, crusty, burning and stinging.The condition is caused by bacteria entering through a scratch or other tiny wound in the eye. So you might think that keeping your eyes free of make-up is a good way to avoid infection, but in fact the opposite is true. It is found that people who don't wear make-up are more prone to blepharitis.Blepharitis can usually be treated with good eye hygiene and applying a warm compress to the eye. However, if it doesn't go away, or if you suffer repeated infections, you should be referred to a specialist as there may be a damage to the eye or an underlying health complaint such as a skin condition.
