As people enter their 40s, they start to develop presbyopia (see #4). Regardless of whether or not you've had Laser vision correction, this process will happen to you. Your surgeon can create an effect known as monovision. This means that one eye will be left slightly nearsighted, thus allowing you to focus on print such as labels and menus without reading glasses, and perhaps allowing you to read into your 50s. As one gets older, it will be necessary to wear reading glasses. Furthermore, if you are over the age of 40 and are used to removing your glasses to read, you must realize that this will no longer be an option following a full correction of your nearsightedness with the surgery.

Shortly after you have had the procedure, it is possible that you may require a temporary pair of reading glasses if you are approaching your 40th birthday since the laser, by design, causes an early overcorrection that normally goes away with time.
