Just because you received EyeGlass Numbers does not mean that you need glasses. If your vision falls within the "green zone" (see the image below) in the vision summary dashboard of the website, it implies that you have "normal" vision and probably don't need glasses.
If your results are out of the green zone then it's possible that you need corrective glasses (refractive vision correction). If you feel that you are experiencing issues with your vision, you should talk with your eye doctor. The Personal Vision Tracker and VisionCheck do not check your eye's health and does not replace a thorough check up with your eye doctor.
