Hyperopia vs. Presbyopia

Hyperopianoun

(pathology) A disorder of the vision where the eye focusses images behind the retina instead of on it, so that distant objects can be seen better than near objects.

Hyperopianoun

An abnormal condition of the eye in which, through shortness of the eyeball or fault of the refractive media, the rays of light come to a focus behind the retina, making vision for distant objects better than for near objects; farsightedness; - called also hypermetropia. Cf. Emmetropia.

Hyperopianoun

abnormal condition in which vision for distant objects is better than for near objects

Presbyopianoun

Inability of the eye, due to ageing, to focus on nearby objects; farsightedness

Presbyopia

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 presbytia.

Presbyopianoun

farsightedness resulting from a reduced ability to focus caused by loss of elasticity of the crystalline lens with age

Presbyopia

Presbyopia is physiological insufficiency of accommodation associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects. Symptoms include difficulty reading small print, having to hold reading material farther away, headaches, and eyestrain.
