➊ One million colours?
The human eye can distinguish approximately one million different colours — amazing, right?
➋ Upside down?
Every image that hits our retina is actually upside down. Luckily, our brain flips it so we see right-side up.
➌ The body’s fastest muscle?
The orbicularis oculi — the muscle used for blinking — is the fastest reacting, responding in less than 1/100th of a second.
➍ Lucky green?
Green eyes are the rarest natural eye colour. Only around 2% of the world’s population has them.
➎ More than just seeing?
Optometrists can detect early signs of conditions like diabetes, high blood pressure, and even brain tumours through eye checks. Your eyes are incredible!
