Amyopic (nearsighted) child wears contact lenses that allow her to have clear distant vision. the power of the lenses of her eyeglasses is -3.00 diopters. without the corrective lenses, what is the far point of the girl?

0.3 m

Explanation:

When a person is myopic it means that light rays from distant object are focused in front of retina so in order to correct this, we use concave lens. The concave lenses focuses these rays on the retina.

Wearing glasses will not change the eye in any way. The diverging lens is simply used to form an image of the object at a distance where the myopic person can see it clearly. Another myopic individual that is not wearing a lens can see clearly objects that fall between their near point and their far point, as well as an individual wearing glasses can see images that fall between their near point and their far point.

Lens' power= -3 diopters = 1/ focal length,f.

Therefore, f= 1/-3 = - 0.3

Far point = -(-0.3) = 0.3 m

exercising at a moderate intensity, and slowly increasing the duration.
