Vision Changes After 40

Even if you have had perfect vision your whole life – or if you have had your vision corrected with laser surgery – your vision will continue to change as you grow older. Presbyopia is one such condition that can naturally occur to most adults over age 40.

Presbyopia occurs when the eye’s natural lens begins to lose flexibility which allows it to shift focus from far-to-near. Reading glasses become necessary to read things like smart phones, menus, medicine bottles and other items with fine print.

Although Laser Vision Correction cannot correct presbyopia by restoring focusing power to the lens, there are surgical options for good candidates to help improve range in vision. These include Monovision or Blended Vision with LASIK and Refractive Lens Exchange.


With Monovision or Blended Vision, we correct the dominant eye for distant vision while the other eye is focused for near vision. This technique can help reduce or eliminate the need for glasses by allowing you to have both near and far vision correction. For some individuals, it can take a little time to adjust to so most doctors recommend patients try using monovision contact lenses before permanently altering their eyes.


Depending on your individual eye measurements and vision needs, Refractive Lens Exchange (RLE) is another surgical alternative to allow for restoration of full range vision in patients with presbyopia. As opposed to Laser Vision Correction which reshapes the front of the eye to improve visual focus, RLE replaces the dysfunctional natural lens of the eye with a clear artificial lens designed to enhance the eye’s range in focus.
