The phenomena of light responsible for the working of the human eye is

Options

A. Reflection
B. Refraction
C. Power of accommodation
D. Persistence of vision

Explanation

To solve the question about the phenomenon of light responsible for the working of the human eye, we can follow these steps:

### Step 1: Understand the Structure of the Eye
The human eye consists of several parts, including the cornea, lens, iris, pupil, and retina. Each of these components plays a role in the process of vision.

### Step 2: Identify the Role of the Lens
The lens of the eye is a crucial part that helps focus light onto the retina. It is a transparent structure that can change its shape to adjust the focus for near or distant objects.

### Step 3: Explain the Process of Refraction
Refraction is the bending of light rays when they pass from one medium to another. In the case of the eye, light rays enter through the cornea and then pass through the lens, where they are refracted to form a clear image on the retina.

### Step 4: Conclude with the Answer
Since the lens of the eye is responsible for bending (refracting) light to focus it on the retina, the phenomenon of light responsible for the working of the human eye is refraction.

### Final Answer
The phenomenon of light responsible for the working of the human eye is **refraction**.
