Definition: A contact lens is a lightweight corrective, cosmetic or therapeutic device that is usually placed directly onto the cornea of the eye. Contact lenses have many benefits for wearers, including appearance and practicality. Many people choose to wear contact lenses as opposed to eyeglasses as they do not steam up, they provide a wider field of vision, and they are more suitable for a number of sporting activities.
Contact lenses vary according to construction material, wear time, replacement schedule, and design. In the United States, contact lenses are considered medical devices and require a prescription by a qualified eye care practitioner.
