Is your overall vision equivalent to or better than your better eye's vision?

Pretty much. This is how monovision or "blended vision" works in contact lens and LASIK patients. The challenge with these people (over about 43) is how to address both myopia (nearsightedness) and Presbyopia (age-related farsightedness). If the eye set for distance...
