A corrective lens is a lens that is typically worn in front of the eye to improve daily vision. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye. Intraocular lenses are surgically implanted most commonly after cataract removal but can be used for purely refractive purposes.

Browline glasses are a style of eyeglass frames where the "bold" upper part holding the lenses resembles eyebrows framing the eyes. They were very popular during the 1950s and 1960s, especially in the United States of America. The glasses were first manufactured by Shuron Ltd in 1947 under the "Ronsir" brand, and quickly emulated by various other manufacturers. The design became the most common style of eyeglasses throughout the 1950s and the early 1960s before it was surpassed in popularity by solid plastic styles. Browlines enjoyed a renaissance as sunglasses in the 1980s before returning to popularity in the 2010s, with the rise of retro style and the hipster subculture.
