Sympton

Some common causes of dark circles under the eyes are fatigue, lack of sleep, allergies, smoking, sun exposure and genetics. Dark circles under the eyes can be puffy and possibly blur vision. The dark circle is an indication that enough oxygen is not reaching the tissues of the body. In some rare cases, lack of vitamins can cause dark circles under the eyes. This is relatively uncommon. Nevertheless, if you're not eating a balanced healthy diet, you may see dark circles. And sometimes changing to a more healthy diet can help to
diminish those dark circles.
