When shifting focus from a distant object to a near one, which outcome arises when the eye's lens fails to adequately increase its curvature?

A)Enhanced depth of field perception
B)Blurred vision at near distances
C)Improved contrast sensitivity overall
D)Reduced risk of developing myopia

💡 Explanation

If the lens cannot increase its curvature sufficiently via the ciliary muscle, the focal point falls behind the retina for near objects, because accommodation is inadequate. Therefore, near vision blurs, rather than depth perception improving as the light isn't focused correctly.
