What Causes Puffy Eyes?
Apart from lack of sleep, eye puffiness may be caused by stress, crying, allergy, irritation or infection (which should be treated). Basically the puffiness is a result of excess fluid accumulating in the soft tissue that surrounds the eye. A cold compress can smooth down the area and help disperse the swelling.
It's worth noting, that in addition to common, relative harmless causes, there are some rare but serious conditions that may cause persistent puffiness, particularly if accompanied by facial swelling, so do check with a doctor if if you are unsure.
