|Normal site is usually considered 20/20 visual acuity or close to that standard, with binocular vision and a visual field in both eyes of approximately 170°. An individual may be myopic or near-sighted, hyperopic or far-sighted, or have astigmatism present based on the curvature of the eye. They may require glasses or corrective lenses to see clearly; however, these refractive errors of the eye are still considered normal vision.|
