If you wear contact lenses, avoid wearing them while you sleep or for more than 19 hours. Unless you are wearing special lenses that are made for wearing overnight, your contact can deprive your eyes of oxygen and lead to extreme discomfort and possibly serious permanent damage to your sight.
When it comes to puffy eyes, there is a quick and easy solution which can literally cure you of the problem. Stop eating salt! The more salt you eat, the more water you retain, and that will become visible around your eyes. Reduce your sodium and your puffiness will disappear.
If you want your eyes to look and feel their best, drink lots of water. The more hydrated you are, the less you will suffer from dark circles. Hydrated skin doesn't allow the blood vessels to show, ensuring that your raccoon eyes (dark circles) become a thing of the past.
