Answer

To answer the question, "The eye lens focuses light falling on it onto a light-sensitive screen present at the back of the eye called the _________", we can follow these steps:

### Step 1: Understand the Structure of the Eye
- The human eye consists of various parts, including the lens, retina, pupil, iris, cornea, and sclera. Each part has a specific function related to vision.

### Step 2: Identify the Function of the Eye Lens
- The eye lens is responsible for focusing light that enters the eye. It bends (refracts) the light rays to form a clear image.

### Step 3: Locate the Light-Sensitive Screen
- The question specifically asks for the light-sensitive screen at the back of the eye. This is where the image formed by the lens is projected.

### Step 4: Identify the Correct Term
- The light-sensitive screen at the back of the eye is known as the **retina**. The retina contains photoreceptor cells that detect light and send signals to the brain to create visual images.

### Step 5: Confirm the Answer
- Based on the structure of the eye and the function of the retina, we can conclude that the correct answer to fill in the blank is **retina**.

### Final Answer:
