Dull reflex to light is a test to check the functional activity of the pupil, divided into direct reflex to light and indirect reflex to light. For direct light reflex, the pupil is usually illuminated directly with a flashlight and its dynamic response is observed. In a normal person, the pupil narrows immediately when the eye is stimulated by light and recovers quickly when the light source is removed. Indirect light reflex means that when light is shone on one eye, the pupil of the other eye immediately narrows, and when the light is removed the pupil expands. When examining indirect light reflexes, one hand should be used to block the light to avoid direct light reflexes in the examining eye. The appropriate diet for patients with blunted reflexes: 1, blueberries Blueberries contain a large number of vitamins, amino acids, minerals and other components, have a good nutritional health effects.
