Why do people become nearsighted after LASIK or receiving a higher glasses prescription?

It’s not unusual for people who undergo LASIK to become nearsighted again after two or three years because you’re changing the structure without changing how the person functions. That’s why even when you’ve fixed it so now they can see from far away, whether with LASIK or glasses, you haven’t changed their system, so whether somebody has had LASIK or you’re giving them an eyeglass power now to see far away, if they continue to over-focus, they will make themselves nearsighted.
