farsightedness, or hyperopia (hiper-ope-ah; far vision), occurs when the parallel light rays from distant objects are (1 ) behind the retina
—at least in the resting eye, in which the lens is flat and the ciliary muscle is relaxed, see part (c) in the figure. hyperopia usually results from an eyeball
that is too short or from a lazy lens. people with hyperopia see distant objects clearly because their ciliary muscles contract continuously to increase the
light-bending power of the lens, which moves the ( 2 ) point forward onto the retina. however, the diverging rays from nearby objects are
focused so far behind the retina that even at full bulge, the lens cannot focus the image on the retina. therefore, nearby objects appear blurry, and ( 3
) individuals are subject to eyestrain as their endlessly contracting ciliary muscles tire from overwork. correction of hyperopia requires convex
corrective lenses that converge the light rays before they enter the eye. thus, farsighted people can see faraway objects clearly and require (4
) lenses to focus on nearby objects.
unequal curvatures in different parts of the cornea or lens cause astigmatism (ah-stigmah-tizm) in this condition, blurry images occur because points of
light are focused not as points on the (5 ) but as lines (astigma = not a point) special cylindrically ground lenses or contacts are used to
correct astigmatism

Explanation:

• For the first blank, in hyperopia (farsightedness), light rays are focused behind the retina.
• The second blank: The ciliary muscles contract to move the focal point (where light converges) onto the retina.
• The third blank: People with hyperopia (hyperopic individuals) have issues.
• The fourth blank: They require corrective lenses (convex as mentioned) for near - vision.
• The fifth blank: In astigmatism, light should be focused as points on the retina.
