The chapter “The Human Eye and the Colourful World” in the UP Board Class 10 Science Book explains the structure and working of the human eye. Students learn about how we see objects, accommodation of the eye, and defects of vision like myopia, hypermetropia, and their corrections using lenses.
It also covers beautiful optical phenomena such as dispersion of light, rainbow formation, and scattering, which explain why the sky appears blue and sunsets look red.
This chapter combines concepts of physics and biology, enhancing understanding of light behavior and human vision — key for board exam preparation and scientific awareness.
