Question

Quizplus · Accepted Answer

Dark adaptation involves the accumulation of rhodopsin, a light-sensitive pigment found in the rod cells of the retina. As rhodopsin accumulates, it allows for better sensitivity to low levels of light, which is necessary for vision in dimly lit environments. The speed of dark adaptation can vary based on factors such as age, health, and the amount of light exposure prior to entering a dark environment. However, it generally takes longer than light adaptation. Dark adaptation does not result in inhibition of rod function; rather, it enhances rod sensitivity. While there may be some improvement in acuity and color vision during dark adaptation, these changes are not the primary focus of the process.
