Legal blindness refers to a central visual acuity of 20/200 or below or a field of vision no more than 20 degrees while wearing eyeglasses or contact lenses. Visual acuity refers to what you can see directly in front of you (sharpness of your vision), while field of vision is what you can see above, below, and to your sides. Legal blindness is not the same as total blindness, which is the full loss of all visual perception. Legally blind individuals can still see light even though they experience blurry vision.
