Your retina is in the very back of the eye. It holds millions of cells that are sensitive to light. The retina takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing.
Q. How does the eye flip an image?
How do eyes work? The images we see are made up of light reflected from the objects we look at. Because the front part of the eye is curved, it bends the light, creating an upside down image on the retina. The brain eventually turns the image the right way up.

Q. What are the 8 structures of the eye?
- Parts of the Eye. Here I will briefly describe various parts of the eye:
- Sclera. The sclera is the white of the eye.
- The Cornea. The cornea is the clear bulging surface in front of the eye.
- Anterior & Posterior Chambers. The anterior chamber is between the cornea and the iris.
- Iris/Pupil.
- Lens.
- Vitreous Humor.
- Retina.
The cornea, a clear window at the front of the eye, covers the iris and the pupil. A clear lens, located behind the pupil, acts like a camera lens by focusing light onto the retina at the back of the eye. The retina is a light-sensitive inner lining at the back of the eye.

Q. Can hummingbirds recognize humans?
Hummingbirds recognize and remember people and have been known to fly about their heads to alert them to empty feeders or sugar water that has gone bad. Hummingbirds can grow accustomed to people and even be induced to perch on a finger while feeding.
Q. How often should you change hummingbird sugar water?
You must change your feeder’s nectar, even if it looks like it hasn’t lost a drop, on a regular basis. During hot weather, change it every two days. In milder weather, once a week is fine.
Q. Where do hummingbirds sleep at night?
They mostly sleep on branches or on the nest, and it’s been known for them to even hang upside down. If you see a hummingbird at night hanging or appearing to breathe very slowly, leave it where it is. It’ll just be in its state of torpor getting a good rest. Torpor is also a way for them to survive on colder nights.
