the reading part of the lens is only a circle - it does not cover the whole lens...to perforal vision is all blurred and more like bifocals...will give you a headache...terrible!!
couldn't leave these glasses on at all. they were too blurry. i had to hold what i was reading very close to my face to see. i ordered the 3.0-level reading glasses. complete waste of money.
