Find the incorrect match

Options

A. cornea acts as refracting structure of eye
B. Choroid prevents internal reflection of light rays within eye
C. Lens regulates the amount of light entering the eye
D. Suspensory ligaments attach the lens to ciliary bodies

Answer

To solve the question "Find the incorrect match," we need to evaluate each of the given statements regarding the structures of the eye and their functions. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Evaluate the first statement: "Cornea acts as refracting structure of the eye."**
- The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. It is responsible for most of the eye's total optical power due to its curvature.
- **Conclusion:** This statement is **correct**.

2. **Evaluate the second statement: "Choroid provides internal reflection of light within the eye."**
- The choroid is a layer of blood vessels and connective tissue between the sclera and retina. It provides nutrients to the outer layers of the retina and helps absorb light to prevent reflection within the eye.
- **Conclusion:** This statement is **correct**.

3. **Evaluate the third statement: "Lens regulates the amount of light entering the eye."**
- The lens is responsible for focusing light onto the retina, but it does not regulate the amount of light entering the eye. The size of the pupil, which is controlled by the iris and ciliary muscles, regulates the amount of light that enters the eye.
- **Conclusion:** This statement is **incorrect**.

4. **Evaluate the fourth statement: "Suspensory ligaments attach the lens to ciliary bodies."**
- The suspensory ligaments (also known as zonules) connect the lens to the ciliary body, allowing the lens to change shape for focusing.
- **Conclusion:** This statement is **correct**.

### Final Answer:
The incorrect match is the third statement: **"Lens regulates the amount of light entering the eye."**
