The Monovision Option For Patients Over Age 40 Many people around the age of 40 begin to have trouble reading up close due to the natural weakening of the focusing muscles of the eye, which is known as ëpresbyopiaí. The monovision option simply means that we leave one eye a little nearsighted after LASIK. Leaving your myopia a little under-corrected or your hyperopia a little over-corrected provides you with some reading ability as you age. Monovision will not eliminate your need for glasses to read fine print, but is useful for reading your watch, opening your mail or reading price tags. The disadvantage is that your distance sharpness will not be as good and you will have more difficulty with activities such as driving at night or with sports such as golf or tennis. If you are in monovision contact lenses already, then the monovision option is ideal for you. You can ask us to try you in monovision contact lenses if you think this may be of benefit. In general, 85% of patients over age 40 prefer the best distance vision possible in both eyes and wear reading glasses when needed, declining the monovision option. Letís decide about monovision before your procedure day.
