Final answer:
A. The 6. cornea with the help of the lens and the vitreous humor, focuses images on the 4. retina
B. Visual 2. accomodation occurs for close vision, as the lens changes its shape to bring the image into__
C. The changes in the lens are brought on by contraction of the 5. cillary muscle.
Step-by-step explanation:
To focus on near and far objects, the human eye undergoes a process called accommodation. This process involves changes in the shape of the lens to adjust the focal length, thereby ensuring that images are focused precisely on the retina.
Completing the statements about how the eye focuses on near and far objects:
- The cornea, with the help of the lens and the vitreous humor, focuses images on the retina.
- Visual accommodation occurs for close vision, as the lens changes its shape to bring the image into focus.
- The changes in the lens are brought on by contraction of the ciliary muscle.
In summary, for statement A, the correct option is the cornea and the retina. For statement B, the phenomena is accommodation and the state achieved is focus. Finally, for statement C, the structure responsible is the ciliary muscle.
