TED-Ed: Eye vs. camera - Michael Mauser

The video explores the differences between human eyes and cameras in perceiving the world. It highlights how eyes and cameras both have lenses and photoreceptors but function differently. The eye's lens changes shape to focus, unlike a camera's lens. Human retinas have multiple photoreceptors, leading to color perception differences. The video also discusses the uneven distribution of photoreceptors in the retina, causing phenomena like blind spots and visual illusions. Eye movements and the brain's role in vision are also covered, emphasizing the evolutionary efficiency of human vision despite its imperfections.

How does the lens in a human eye focus on objects compared to a camera lens?

• By using a zoom function

• By rotating around the object

• By moving closer or further from the object

• By changing its shape

Why don't humans need color filters like cameras do?

• Because human eyes can only see in black and white

• Because human eyes have a higher resolution

• Because human eyes have photoreceptors that respond to different wavelengths

• Because human eyes have a built-in zoom function

What happens to faint stars when you look directly at them?

• They appear brighter

• They change color

• They seem to disappear

• They become larger

What is the reason for the 'blind spot' in human vision?

• Lack of photoreceptors in a certain area

• Presence of too many photoreceptors

• Excessive light exposure

• Overlapping of visual fields

Why can't you see your eyes move when looking in a mirror?

• Because your eyes move too slowly

• Because the mirror is too far away

• Because your vision briefly stops during eye movement

• Because the mirror reflects light differently
