What changes take place in the shape of eye-lens:
when the eye is focused on a distant object?
उत्तर
When the eye is focussed on a distant object, the eye lens gets stretched and becomes thinner. This is because, when the eye is focused on a distant object, the ciliary muscles are completely relaxed. The relaxed ciliary muscles pull the suspensory ligaments tightly. As these ligaments become tight, they pull the eye lens, because of which the eye lens becomes thinner (or less convex).
