False.
Explanation:
Accommodation is the ability of the lens of the eye to adjust its focal length to focus images of objects at different distances on the retina. The retina itself is the light-sensitive layer where the image is formed, but the adjustment of focal length happens by changing the curvature of the lens with the help of ciliary muscles.
