The human organ that does not grow is the eye.
While most parts of the body continue to grow until adulthood, the eye essentially reaches its full size during childhood.
This is because the eye is a complex organ that relies on precise structures and proportions for optimal vision. Unlike other organs that can grow and adapt, the eye's delicate balance is crucial for its function.
While the eye doesn't grow in size after childhood, it does continue to develop and change throughout life. For example, the lens continues to harden and the vitreous humor can shrink, potentially leading to age-related vision changes.
