The top image set shows two red lines going from the back of the owl into the eye, forming a V as it goes to the back and out of the eye to show farsightedness.
- Farsightedness causes nearby objects to seem blurry, while distant objects appear clear.
- This happens because the light rays that enter the eye focus too far from the lens.
- The eyeball is too short or the cornea is not curved enough.
- The image of the owl forms before reaching the retina.
The bottom image shows an owl on the left and an eye on the right. There are two red lines going from the back of the owl into the eye, forming a V as it reaches the back of the eye. A convex lens is placed just before the red lines enter the eye to show how farsightedness can be corrected.
- The convex lens bends the light rays toward each other before they enter the eye.
- The image of the owls now passes throught the concave lens, forming on the retina, instead of in front of it.
