But the sure thing is that contact prescription has nothing to do with legal blindness. To be considered as legally blind, a person should only have a corrected vision of 20/200 or worse in their best seeing eye and the vision field is confined to only 20 degrees. And you are not legally blind if your vision can be corrected to 20/20 with the help of contact lenses, glasses, etc. So no matter what your prescription is, be it 0.0, -5.75 or even -25, you are not legally blind if your best corrected vision is better than 20/200.

Although a lot of people use this term I'm legally blind without glasses that is totally inaccurate. First legally blind is defined in terms of BEST CORRECTED VISION. Meaning it cannot be applied to conditions corrected with glasses or contacts. Second while myopic individuals like you have poor distance vision without glasses you have 20/20 vision when holding something about 6-8 inches away. JCH III MD.
