Question
In the whole process of seeing an object, the light undergoes ____ outside the eyes and ____ inside the eyes.
- Reflection, transmission
- Transmission, reflection
- Reflection, refraction
- Refraction, transmission
Hint:
The light from the object enters the eye and forms an inverted image at the retina.
The correct answer is: Reflection, refraction
In the whole process of seeing an object, the light undergoes reflection outside the eyes and refraction inside the eyes.
After light bounces off an object such as a tree or book, it still goes straight, but in a new direction. When light enters our eyes, we see objects. Light entering the eye is first bent by the cornea, the transparent window at the outer front of the eyeball. The cornea provides most of the eye's refractive power. Then it is refracted through the eye lens and an image is formed on the retina.

What is the eye defect shown in the picture below?
The correct option is a)Myopia.
- Nearsightedness or myopia is an eye condition caused by a refractive error that causes distant objects to appear blurry. A nearsighted person can clearly see nearby objects.
- Myopia means that the focus of the eye is in front of the retina instead of on it. The retina is the surface at the back of the eye that collects light.
- It converts light into electrical impulses that the brain interprets as images. Blurry vision can occur when the eye focuses light in front of the retina.
