What is binocular vision?

Explanation

**Step-by-Step Solution:**

1. **Definition of Binocular Vision**: Binocular vision refers to the ability of both eyes to focus on the same object simultaneously. This coordinated effort allows for depth perception and a three-dimensional view of the world.

2. **Mechanism of Binocular Vision**: When both eyes look at an object, they send slightly different images to the brain. The brain processes these images together, allowing us to perceive depth and distance, which is essential for tasks like judging how far away an object is.

3. **Stereoscopic Vision**: Binocular vision is often referred to as stereoscopic vision. This term emphasizes the three-dimensional aspect of the vision that results from the brain combining the two slightly different images from each eye.
