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 chang 606 $aPresbyopia 608 $aElectronic books. 615 0$aPresbyopia. 676 $a617.7/55 676 $a617.755 700 $aSchachar$b Ronald A.$f1941-$0920698 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910463148403321 996 $aThe mechanism of accommodation and presbyopia$92064913 997 $aUNINA
