老花 Presbyopia(重定向自Near Point)
![]() 老花(Presbyopia)是眼睛出现老化而导致晶状体不能对近物对焦的视力问题。患者因而在看近物时视物变得模糊。 患者在看近物时视物变得模糊。特别是在光线不足下,问题会更明显严重,这是因为光线不足下曈孔会扩大,因而景深变窄。 另一病征是患者在把焦点大幅转移时的瞬间影像会暂时性变得模糊,这是因为眼睛变焦迟缓所致。

Presbyopia 老花(重定向自Near Point)
![]() ![]() Presbyopia (from Greek presbys (πρέσβυς) = old man + ops (ὤψ) = see like, sight > meaning literally trying to see as old men do) is a condition associated with aging in which the eye exhibits a progressively diminished ability to focus on near objects. Presbyopia’s exact mechanisms are not fully understood; research evidence most strongly supports a loss of elasticity of the crystalline lens, although changes in the lens’s curvature from continual growth and loss of power of the ciliary muscles (the muscles that bend and straighten the lens) have also been postulated as its cause. |
