In less than a second, a young human eye can accommodate from infinity to closer than 10 cm. Accommodation occurs with minimal effort and can be rapidly repeated with no apparent evidence of fatigue. Unfortunately, maximum accommodation decreases throughout life and by the fifth decade leads to presbyopia, the inability to read at a normal working distance. Interestingly, the mechanism by which the human eye is able to adjust focus has been debated for over 300 years. No previous theory has been put forth that can account for all the physical changPresbyopiaPresbyopia.617.7/55617.755Schachar Ronald A.1941-1806204MiAaPQMiAaPQMiAaPQBOOK9910968558703321The mechanism of accommodation and presbyopia4355249UNINA
