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 as your age is now 20 years so 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. If 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.

Myopic around- 3 D has lots of advantage after 40 yrs.  If you have decided for refractive surgery ,go for Smile better than  LASIK ,only 2.5 to 3 mm laser incision but it is only for 20 yrs ,after 40yrs you will have to use reading glasses changing every two yrs till your cataract surgery in old age.

U can get your myopia corrected by LASIK laser.
