What will happen to my near vision if I am 40 years or older or what will happen when I reach 40?

Sometimes between ages 40 and 45, the eye muscles start to weaken and do not allow us to read close up anymore. This is called presbyopia and will sooner or later affect everybody. This process is not affected by LASIK. That said, if you are near-sighted and get that corrected by LASIK, you may lose the ability to see close-up that near-sightedness afforded you after 40. This is why we advocate monovision after age 40, it allows retaining a little nearsightedness to help with some close up tasks.
