what is your age? What is your prescription, that is how near sighted are you? have you had any dilated retinal exams looking for retinal problems? if so what was seen?
you have moderate amount of myopia (near sighthedness). If your retina is healthy, you can expect to have a pretty normal life with good eye sight and minimal problems. It is possible that the strenght of the contacts may need to increase as time goes on but that is simply a matter of updating the prescription. Most people with your level of near sightedness do not go blind due to problems. You should do just as well, Dr. Stevens
