Eye prescription allows us to determine a person's vision quality, that is, their ability to perceive details at close, medium, or long distances. The diopter is the unit of measurement used in optics to designate the refractive capacity of a lens. It determines a person's ability to correct blurred vision.
The type of lenses you should use, the shape, and dimensions of the frames all influence how you choose glasses that make you feel comfortable and allow you to see well. Likewise, the right fit depends on your lifestyle and activities.
