Blurred eye. I need any surgery for eye?

Hi Doctor, I am using spectacles for the past 7+ years. I used to wear while working in the office and watching tv etc. In the last 2 years or so, I was putting on spects continuously and recent the times, my sight power seems to be increasing. I consulted vasan eye care hyderabad and warangal branches and they were telling my right eye became weak and hence my right eye vision is blurred. Doctor told me that blurriness is because of longer usage of spectacles. I did get the same feedback from 2 doctors. I was changing my spectacle to new power, my right still showing as blurred. I experimeted by closing left eye and tried to see with right eye and the result is from my spectacles also blurriness is there for my right eye. So, In this case, should I consider that only one eye is working? Is there a permanent solution for my blurred eye? Should I need any surgery for eye? Please advise...
