This is called presbyopia, a condition that is caused by a progressive loss in flexibility of the lens of the eye. This impairs the ability to shift focus between near and far objects. The process is normal and natural, but not preventable. Presbyopia affects virtually everyone, as the Baby Boom generation now is learning. Every year, four million Americans join the ranks of presbyopes and begin an often frustrating adjustment process.
Some bifocal glasses slip down sweaty noses at the gym, or clash with dress-up clothes.
Others put on and take off reading glasses hundreds of times a day, misplacing, searching for, losing and replacing them. Monovision contact lenses freed a few presbyopes from eyeglasses, but sometimes at the cost of depth perception, especially at night. My patients have really enjoyed putting away their bifocal and reading glasses. Almost everyone has mentioned it. This site is governed solely by applicable U.S. laws and governmental regulations.
