I was extremely near-sighted my whole life (literally couldn't read the Big E in the chart) and had Lasik at age 42. Had mono-vision done. They told me I would probably need cheaters within 3-4 years, but here I am at age 49, barely hanging on.
Interestingly, I heard there is a muscle of some sort in your eye socket that squeezes the eye, ever so slightly, which is what makes you able to focus close up. Essentially, as you age, this muscle loses it's ability to perform, thus the need for readers.
My wife is super pissed, she always had great vision, last few years has to have the cheaters and I don't, and I always wore glasses.
