Just because you received EyeGlass Numbers from the Full Test, it doesn't mean that you need glasses. If your vision falls within the "green zone" in the vision summary dashboard, 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 Test does not check your eye health and does not replace a thorough check up with your eye doctor.
