Innovations in Emmetropia: Latest Treatment Advances
What is Emmetropia? Emmetropia refers to an eye with perfect vision, in which light rays enter the eye and focus directly on the retina, eliminating the need for corrective lenses. In an emmetropic eye, the cornea and lens work together to precisely refract light, resulting in sharp and clear images from a distance and up close. This is the ideal...
