A lens is a transparent optical structure that bends (refracts) light to form a focused image. In eye care, “lens” can mean the eye’s natural crystalline lens, a contact lens worn on the cornea, or an intraocular lens implanted during cataract surgery. Clinicians also use specialized diagnostic lens devices to examine internal eye structures. Across these settings, the core goal is the same: guide light precisely to improve vision or enable accurate examination.
