When light receptors in the eye detect bright light, a reflex is triggered, making circular muscles in the iris contract and radial muscles relax, making pupils smaller.
Lorsque les récepteurs lumineux de l'œil détectent une lumière vive, un réflexe est déclenché, provoquant la contraction des muscles circulaires de l'iris et la relaxation des muscles radiaux, ce qui réduit le diamètre des pupilles.
