[C]. Hypermetropia is corrected by using spectacles containing convex lenses.
[D]. The whole purpose of using a convex lens is to reduce the converging power of the eye-lens.
Q12
Recently, in a science class test, you are asked a question where you have to say whether the statements are correct or not?
[A]. Presbyopia is that defect of vision due to which an old person cannot see the nearby objects clearly due to loss of power of accommodation of the eye.

Class 10 Science Chapter 10 Important Questions
What is the function of Iris?
Iris is a dark muscular diaphragm that controls the size of the pupil.
What is meant by accommodation of eye?
The ability of the eye lens to adjust its focal length is called accommodation.
Why do stars twinkle?
The twinkling of a star is due to atmospheric refraction of starlight. The starlight, on entering the earth’s atmosphere, undergoes refraction continuously before it reaches the earth.This makes continuously change in star’s position and we see the twinkling of stars.
Why does sky apear blue in colour?
The molecules of air and other fine particles in the atmosphere have size smaller than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end. When sunlight passes through the atmosphere, the fine particles in air scatter the blue colour (shorter wavelengths) more strongly than red. The scattered blue light enters our eyes and we see blue sky.
