- n. Inability of the eye to focus sharply on nearby objects, resulting from loss of elasticity of the crystalline lens with advancing age.
Century Dictionary and Cyclopedia
- n. Diminished power of accommodation for near objects, incident to advancing years, and due to progressive loss of elasticity in the crystalline lens.
GNU Webster's 1913
- (Med.) A defect of vision consequent upon advancing age. It is due to rigidity of the crystalline lens, which produces difficulty of accommodation and recession of the near point of vision, so that objects very near the eyes can not be seen distinctly without the use of convex glasses. Called also
- n. a reduced ability to focus on near objects caused by loss of elasticity of the crystalline lens after age 45
- From New Latin, from Ancient Greek πρέσβυς (presbys, "old man"), and New Latin -opia ("vision problem"), from Ancient Greek ὤψ (ōps, "eye"). (Wiktionary)
- New Latin : Greek presbus, old man; see per1 in Indo-European roots + -opia. (American Heritage® Dictionary of the English Language, Fourth Edition)

“The inability to focus on close objects, known as presbyopia, is a natural part of aging that occurs when the lenses of the eyes become less flexible.”
“And when you hit 40, that inability to see near—called presbyopia—becomes a bigger problem, meaning that you may need bifocals, or different lenses for seeing close and far.”
“That's because the lens of your eye becomes less flexible as you get older, leading to a condition called presbyopia or farsightedness.”
“It's an all too common vision problem called presbyopia, affecting nearly everyone by the age of 50.”
“This recession of the near point with age is called presbyopia (prez'bee-oh'pee-uh; "old man's vision" G).”
“Old sight," known as presbyopia, is a common defect of vision in advancing years.”
“Still another defect of vision is known as presbyopia or farsightedness due to old age.”
“Early Show" contributor Taryn Winter Brill reported it's often caused by a condition called presbyopia.”
“By the time we reach our 50s and 60s, the eyes lose the ability to focus to different distances - a condition called presbyopia that's a natural part of the ageing process.”
