I went to the optometrist doctor to check my vision and they say i got asitigmasim on right eye with a prescription -0.25.However,2 days recently,the other eye is getting blurry.They gave me an eye drop because they said my eye is dry.However,when i was in my country,my vision is normal When i came to study abroad,1 months recently,it is getting worse.What can i do to improve my eye sight?or are there any possible solution.Becuase to be honest,i do not want to wear glasses again.
