This change could be get over by using reading glasses or bifocals. However, the problem of poor vision could be get over easily enough through Lasic surgery. It does not improve the ability of the lens to alter shape or increase the power of the lens. Rather, it makes certain structural changes of the lens to be able to get rid of the need for visual aids.
