Over time, there will be sunglasses syndrome. Second, the anatomy and physiology showed that a small hole under the eyes, called the infraorbital foramen, this hole has an important nerve branches. It is distributed in the eye fissure of the mouth cleft between the skin and nose, in charge of sensory function. Because of the weight of the sunglasses and lens ring focus compress the infraorbital nerve, it will lead to the discomfort of the nerve distribution area, with the extension of the time wearing glasses; there will be local skin numbness, dull, visual fatigue and other symptoms.
