Which of the following is an accurate description of how the eye focuses?
A) For faraway objects, the elastic suspensory ligament holds the lens taut, thus flattening the lens. For nearby objects, the eyeballs turn inward, the pupillae muscle lets less light enter the eyeball, and the suspensory ligament loosens to allow the lens to relax and assume its normal shape.
B) For faraway objects, the elastic suspensory ligament loosens the lens, thus allowing the lens to assume its normal shape. For nearby objects, the eyeballs turn inward, the pupillae muscle lets less light enter the eyeball, and the suspensory ligament tightens to flatten the lens.
C) For faraway objects, the elastic suspensory ligament holds the lens taut, thus flattening the lens. For nearby objects, the eyeballs turn outward, the pupillae muscle lets more light enter the eyeball, and the suspensory ligament loosens to allow the lens to relax and assume its normal shape.
D) For faraway objects, the elastic suspensory ligament loosens the lens, thus allowing the lens to assume its normal shape. For nearby objects, the eyeballs turn outward, the pupillae muscle lets less light enter the eyeball, and the suspensory ligament becomes taught, thus flattening the lens.
E) For faraway objects, the elastic suspensory ligament holds the lens taut, thus flattening the lens. For nearby objects, the eyeballs turn inward, the pupillae muscle lets more light enter the eyeball, and the suspensory ligament loosens to allow the lens to relax and assume its normal shape.
