Accommodation

Quizplus · Accepted Answer

Accommodation refers to the process by which the eye adjusts its focus to see objects at different distances clearly. This involves changing the shape of the lens to focus the visual image on the retina (A). In fish, accommodation is achieved by moving the lens either forward or backward (B), which is different from humans and other mammals who change the shape of the lens. Some animals can change the fluid volume in the optic chamber to adjust focus (C), showing the diversity of mechanisms for accommodation across different species. Therefore, all three statements are correct, illustrating various aspects and mechanisms of accommodation in different organisms.
