It will take some time for your eyes to get adjusted to the new pair. You might feel a bit uncomfortable, dizzying, headache. However, it will pass with in a week or two and you will completely love the glasses. In these one week or two, you need to wear your glasses every day. Please keep making an effort to wear them every day, even though you feel uncomfortable. Keep your lenses clean and move your head as you would normally. Some people wearing glasses for the first time get dizzy or experience headaches, because they are moving their eyes now, not their heads. It will be a conscious effort you make, but after a while you’ll get used to it and do it naturally as you normally would.
