Objective refraction is a technique used in optometry to determine an individual's prescription for eyeglasses or contact lenses without the patient's subjective input. It involves the use of autorefractors or retinoscopes to measure how light changes as it enters the eye, providing an initial refractive assessment that can be refined through subjective testing.

They play a crucial role in enhancing visual acuity and can also serve as fashion accessories or protective gear in various environments.

Contact lenses are thin lenses placed directly on the surface of the eyes to correct vision or for cosmetic purposes. They offer a convenient alternative to glasses, providing a wider field of view and are available in various types, including soft, rigid gas permeable, and hybrid lenses.
