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