"We've found that melanopsin plays a crucial role on the human ability to see how well-lit the environment is. These findings are redefining the conventional system of light detection that so far has only taken into consideration two variables, namely brightness and the amount of incoming light. Our results suggest that brightness perception should rely on a third variable -- the intensity of a stimulus that targets melanopsin."
"Sithole ukuthi i-  melanopsin inendima enkulu ekhonweni lomuntu lokubona ukuthi indawo ikhanya kahle kangakanani. Lokhu okutholakele kuchaza kabusha isistimu evamile yokubona ukukhanya futhi kuze kube manje ecabangele nje izindlela ezimbili kuphela, ukukhanya kanye nesilinganiso sokukhanya okungenayo. Imiphumela yethu ibonisa ukuthi indlela esibona ngayo ukukhanya kufanele incike endleleni yesithathu – ukujula kwalokho okushukumisayo okuqonde ku-melanopsin."
