光喷嚏反射也叫“旋光性喷嚏反射”。人群中有大约10%到35%的人一见到阳光或灯光就鼻腔发痒,容易打喷嚏。还有人在想打喷嚏而又打不出来的时候,看到强光后一下子就打了出来。光是靠眼睛看到的,喷嚏是鼻子打出来的,可谓风马牛不相及的两者,在这个问题上究竟有什么关系呢?
另一个理论认为,把鼻子眼泪通过鼻泪管泄漏是一种光的反射引起喷嚏。
Another theory suggests that tears leaking into the nose through the nasolacrimal duct are a cause of the photic sneeze reflex.
反射光的打喷嚏是医疗条件,其中包括人民打喷嚏突发接触强光,也可能多次连续打喷嚏。
Photic sneeze reflex is a medical condition by which people sneeze with sudden exposure to bright light, and possibly also sneeze many times consecutively.
