# Eye Movement vs Normal Eyes - What's the Difference?

Most people think their eyes move smoothly, but science tells a different story.

## The Science Behind Eye Movement

### Saccadic Eye Movement

Your eyes naturally make small, quick jumps called **saccades** when tracking moving objects. This is normal human behavior.

### Smooth Pursuit

**Smooth pursuit** is the ability to track moving objects without jerky movements. Only about 1% of people can do this naturally.

## Why the Eye Movement Challenge Went Viral

The challenge appeals to everyone's curiosity:
- Am I normal?
- Can I control my eyes this way?
- What does my score say about me?

## What High Scores Mean

- **Psychopath Eyes**: People with high scores may have better sensorimotor integration
- **Smooth Tracking**: Indicates good visual-motor coordination

## How to Improve

Practice makes perfect! The more you play, the better you get at controlling your eye movements.
