Boiled eggs on the eyes is a common physical therapy method to accelerate eye microcirculation and treat eye fatigue or dark circles. It is usually done by boiling a raw egg, and after the boiling temperature has slowly subsided to a temperature acceptable to the human eye, it can be rolled back and forth along the eyelids to heat the skin or lid glands in the eye. The temperature should be as hot as the human eye can tolerate, and not too hot, which can cause skin redness and swelling. If you use this boiled egg on your eyes regularly, it will improve the local circulation of the eyes and relieve visual fatigue. This is a commonly used treatment to relieve fatigue and improve dark circles under the eyes and should be advocated.
