There is no medication or food for improving eyesight or to get rid of glasses. If not interested in glasses then you can try a. Contact lens b. Lasik laser your number will not increase now whether you wear glasses or not as number becomes stable at age of 18-20 yrs. Having said that I advise you to eat balanced diet including green vegetables and seasonal fruits for keeping eyes and body healthy. As you are not comfortable with contact lens then go for lasik. Lasik is a very easy and painless procedure. If you want to get rid of glasses then go for lasik

Height depends on parent height & in male height gets completed by 20- 21 yrs &  if you don't like glass ,you may go for LASIK after 21-22 yrs because by that time you will have stable power,with regards

You should wait till age of 21 years. Or else if your power is stable for past one year you can go for lasik surgery.  Your height also should be stopped by 21 years of age. In a year your height might not be 5 10.
