Question

Where will the image of distant objects be in case of myopia?
A) Before the retina,
B) on the retina,
C) behind the retina,
D) above the retina,

Answer 1

In a normal eye when the light rays which reflected back from the object that we see, the image falls focused on the retina. Due to certain eye conditions the image that is focused does not fall exactly on the retina. The formation of an image may differ from different eye conditions.

Complete step by step solution:
One of such eye conditions is refractive error of the eye. The refractive error of the eye is an average error of the eye. This happens because when the eye cannot focus the image of the object clearly. The outcome of the refractive error is that the vision gets blurry and sometimes it can be severe that it can cause vision impairment. Some of the refractive errors of the eye are myopia which is short sightedness, Hyperopia which is far sightedness, astigmatism which is distorted vision, presbyopia which is unable to read at arm’s length.

The refractive error of short-sightedness where the medical term is Myopia. In this vision condition the person can see the objects that are closer to them clearly, whereas the objects that are far away are not clear, that is the image of the object looks faded. The occurrence of myopia is due to the cornea which is too curved or that the eyeball is too long. In case of myopia the image of the object does not fall on the retina, but it falls before the retina.

Therefore, in myopia the image of a distant object will be formed before the retina.

Hence the option (A) before the retina is the correct answer.

Note: The refractive errors can be corrected using specific types of lenses for different errors. The myopia can be corrected using the concave lenses of appropriate power, the hyperopia can be corrected using convex lenses of appropriate power, the presbyopia can be corrected using bifocal lenses or progressive lenses of appropriate power, the Hyperopia can be corrected using cylindrical lenses.
