I know that humans won't squint their eyes even if exposed to dangerous levels of ultraviolet or infrared light because our eyes simply don't have the capability to detect it. Neither do the irises constrict.
Since the human eye is most sensitive to green light, does this mean that we will squint and/or constrict our irises more readily for green light? Perhaps even when the intensity is safe for our eyes? (Albeit close to dangerous levels)
