Hello. There is no medication or food for improving eye sight or to get rid of glasses.
Get your vision tested and wear glasses.
If not interested in glasses then you can try
a. Contact lens
b. Lasik laser
as your age is now 21 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.
Lasik is a very easy and painless procedure. If you want to get rid of glasses then go for lasik.
