Lens in the human eye is?
ABiconvex
BBiconcave
CSpherical
DCylindrical
Answer:
A. Biconvex
Read Explanation:
- The lens in the human eye is biconvex, meaning it is curved outward on both sides.
- This shape allows the lens to focus light rays precisely onto the retina, enabling clear vision.
- The biconvex lens adjusts its shape through the ciliary muscles to focus on objects at various distances, a process known as accommodation.
- A biconvex lens converges light rays, which is essential for concentrating light on the retina's fovea centralis, the point of sharpest vision.
- The lens's transparency and flexibility are crucial for proper light passage and focusing.
