Though I changed my glasses according to the reading, there is no improvement. Why?

Hello,

Welcome to icilniq.com.

From your attached prescription, I can tell you that there is a very definite change in the power of your glasses and also in the amount of how much you can see. The best to make that difference stand out, that you can do yourself is to cover each eye and look through the other, ideally at an object or letter just visible to normal people around six meters or 20 feet away. You can also try this in different levels of light just as you have compared before. The impression I get from your prescription is that while your myopia has increased in both the eyes, there has been some decrease in the amount of vision in both your eyes. That is to say that the power has increased and the amount you see has come down. As always, testing of glasses is a subjective assessment and varies depending on your suggestion and the optometrist performing the test. In case you are not happy with your current glasses you can always return to the same place for a re-check. I hope this helps.
