This is just some general information. There is an epidemic of myopia world wide especially in Asians. It is due to less time outdoors and more time in front of iPhones, computers, video games, and other prolonged near work. So there are enormous numbers of young people with your problem. There is no way to predict what your final amount of myopia will be. It's like trying to guess your final height. I suggest you see an Eye MD ophthalmologist not an optometrist and see one that specializes in cornea/refractive surgery.
