When I went to the optician to get my new glasses and put them on, I could see clearly sharp and a few days later with those glasses I see less sharp. I called my mother to tell me if it's normal (because my mother is myopic too) and she said yes, and she told me it's normal and it happened to her too, and she told me my eyes got used to it. But I don't know if to trust. And I also surfed the internet to see if my problem is normal or not, but I couldn't find any results that match what I wrote. I don't know if it's a worsening of myopia or because my eyes got used to it. Could anyone tell me if it is normal or not? Or is it just my feeling?
