What You Will Learn?
✅ The ability of the eye to focus on both near and distant objects, by adjusting its focal length, is called the accommodation of the eye.
✅ The smallest distance, at which the eye can see objects clearly without strain, is called the near point of the eye or the least distance of distinct vision. For a young adult with normal vision, it is about 25 cm.
✅ The common refractive defects of vision include myopia, hypermetropia and presbyopia. Myopia (short-sightedness – the image of distant objects is focused before the retina) is corrected by using a concave lens of suitable power. Hypermetropia (far-sightedness – the image of nearby objects is focussed beyond the retina) is corrected by using a convex lens of suitable power. The eye loses its power of accommodation at old age.
✅ The splitting of white light into its component colours is called dispersion.
✅ Scattering of light causes the blue colour of sky.
