1、Why is cylindrical lens used?
A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused in a single dimension or axis.
2、Which defect of the eye can be corrected by using a cylindrical lens?
The defect of the eye that can be corrected by using cylindrical lens is Astigmatism. Astigmatism is caused due to uneven curvature of the eye lens.
3、How do concave and convex lenses correct vision?
Concave Lenses Are for the Nearsighted, Convex for the Farsighted. Concave lenses are used in eyeglasses that correct nearsightedness. ... Placing concave lenses in front of a nearsighted eye reduces the refraction of light and lengthens the focal length so that the image is formed on the retina.
