2.0NCERT Solutions Class 10 Science Chapter 10 Human Eye and Colorful Science: Overview

Light enters the eye through the tough, clear cornea, which protects the human eye. The iris, a muscle behind the cornea, adjusts the pupil size to control the amount of light entering the eye. The iris also gives the eye its color, such as black, brown, or green. Behind the pupil, the lens further focuses light onto the retina, which contains nerve cell that convert images into signals sent to the brain via the optic nerve. The two types of nerve cells are:

1. Cones – responsible for color and bright light vision.
2. Rods – sensitive to dim light.

In low light, the pupil expands to let in more light, while in bright light, it contracts.

Eye Care Tips:

• To avoid strain, ensure proper lighting for activities, and maintain a reading distance of about 25 cm.
• Wash your eyes regularly with clean water and avoid rubbing them.
• Eat foods rich in Vitamin A, like carrots, leafy greens, eggs, and dairy, to support eye health.
• If you experience pain, irritation, or vision issues, consult a doctor and use corrective lenses if needed.

3.0What Will Students Learn in Chapter 10: Human Eye and Colorful World?

• Learning what the different parts of the eye do and what they do in helping us to see.
• In NCERT Solutions Class 10 Science Chapter 10 there is a brief overview of some of the common vision disorders including myopia which is also known as nearsightedness, hypermetropia or farsightedness and presbyopia, and using lenses.
• How the eye is able to change its ability to focus to accommodate nearby or distant visuals.
• How different colors of white light are formed or separated as it passes through a prism.
• Some of the occurrences such as the twinkling of star and the apparent changes in the path of light due to the atmosphere.
• Learning how the sky appears to be blue, and why the Sun appears reddish during sunrise and sunset.
