List of top Science Questions on The Human Eye asked in UP Board X

Range of clear vision of a normal eye is -
(i) Explain with the help of labelled ray diagram, the defect of hypermetropia. How is it corrected by a lens?
Explain with a drawing how hypermetropia is corrected. The near point of a hypermetropic eye is 75 cm. What is the focal length of the lens required to correct this defect? The near point of a normal eye is 25 cm.
The human eye forms the image of an object at its:
The amount of light entering in the eye is controlled by:
Explain the power of accommodation of the eye. Draw a ray diagram for image formation by a convex lens when (a) the object is at a distance of 2f, (b) the object is in between 2f and infinity.
A person having normal eye can clearly see an object, if the distance of the object from the eye is:
A person is unable to see distant objects clearly. Defect in his eyes will be:
A person suffering from short-sightedness can see up to 100 meters. Calculate the nature and the focal length of the lens in order to correct this defect so that he can see objects at infinity hence correct vision. Also, draw the ray diagram.
