1.	A person looking at a mesh of crossed wires is able to see the vertical wires more distincly than the horizontal wires. Why ? How can it be corrected ?
Answer» This problem is due to astigmatism of the eye. This defect is removed using a cylindrical lens with appropriate axis and suitable radius of curvature.
