I was never using glasses outside home. When I got my lenses, WOW! Seeing this whole world so sharp was amazing. I even discovered that there is a river near a way I was driving by bus


The same is when you are using glasses/lenses for a first time. Before everything was blurry and now you have clear vision, brain must adapt to this.
I got my first glasses when I had -2.75 and -2.5. I had headaches at first day when I was using them, but it is passing with time.
