Assertion : when we see an object, the image formed on the retina is real and inverted.

Reason – If the magnification is less than 1 then image formed is real and inverted.

Assertion: A normal eye can clearly see all the objects beyond certain minimum distance.

Reason : The human eye has capacity of adjusting focal length of eye lens.

Assertion : Hypermetropia is the defect of eye in which farther objects can be seen clearly but not nearby objects.

Reason : Hypermetropia is corrected by using converging lens.

Assertion : In myopia defect of vision, light from a distant object arriving at the eye lens get converged at a point in front of the retina.

Reason : The eye lens is producing too much convergence in the incident beam.

Assertion – A hypermetropic person prefers to remove his spectacles while driving.

Reason – When a hypermetropic person wearing the spectacles looks at a distant object, the parallel rays from the distant object get converged in front of the retina. The image thus appeared blurred.

Assertion : The human eye is capable of adjusting the focal length of its eye lens.

Reason : Ciliary muscles adjusts the curvature of the crystalline lens inside the human eye.

Assertion – Doctors prescribe bifocal lens to patients suffering from presbyopia.

Reason – In presbyopia, a person may not be able to see far away as nearby objects due to decrease in the power of accommodation of the eye

Assertion – Pupil regulates and controls the amount of light entering the eye.

Reason – The size of the pupil is controlled by the ciliary muscles.

Assertion – A myopic person is not able to see far away things clearly.

Reason – This happens due to the shortening of the eye ball.

Assertion – In cataract, there is partial or complete loss of vision.

Reason – Crystalline lens of people at old age becomes clear and transparent.
