Elderly farsightedness – Presbyopia
The word presbyopia (lat. presbyopia) in Greek "presbus" means an old person. Presbyopia is a condition associated with age and a decline in the maximum accommodation power of the eye due to changes in the refractive system of the eye. As the eye lens in presbyopia...
Normal eye – Emetropia (lat. Emetropia)
Emmetropia or normal-sighted eye means the refractive state of the eye in which the far point (Punctum remotum) is at infinity, the point of the clearest vision at a distance. In an emmetropic person, the image of the observed object is projected directly onto the...
Astigmatism (lat. Astigmatismus)
The word astigmatism (lat. Astigmatismus) means without a point. Astigmatism is an eye error in which the optical system of the eye has different refractive powers in different meridians. Astigmatism is an eye error in which the optical system of the eye has different...
