Der Sinn des Sehens

Sight is our primary sense, allowing us to navigate and understand the world.

Over 80% of environmental information reaches us visually.

Different animals have varying visual capabilities, from superb to nearly non-existent.

Some animals, like cave dwellers and deep-sea fish, have limited or no sight.

Certain creatures, like some sea creatures, lack eyes.

Some animals, like mole rats, deep-sea fish, and cave salamanders, have very poor eyesight.

Eyes come in different shapes and structures across various animals.

Some ancient animals, like the pearl oyster, have eyes composed only of a pupil and retina with a specific shape.

Most eyes, including human eyes, feature a pupil to let in light and a retina to form images.

Human eyes are a complex visual system with a pupil, lens, retina, and other components.

A simplified representation of an eye, similar to a pearl oyster's eye, highlighting the basic components for light capture and image formation.

Incoming light travels from the object to the eye.

An image is created on the eye's internal surface (retina) after light passes through the eye.

The small opening in the model eye that allows light to enter.

The component inside a model eye where light forms an image for processing. Often paper

A simplified representation of an eye, similar to a pearl oyster's eye, which demonstrates how light forms images.

The image formed on the retina is upside down.

The part of the eye receiving the light from the object, resembling transparent paper in a model.

The small opening in the eye that lets light in. Similar to a hole in the model eye.

The brain flips the inverted image to make it right-side up for us to perceive the world correctly.

A simplified representation of the eye showing how light creates images, often a box with a hole.

Light from an object must enter the eye to create an image.

The eye captures light to form images.

Light passing through a hole creates an upside-down image on the inside surface.

The hole in the eye (pupil) lets light enter, influencing the model's image quality.
