A practical superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit.

The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution.

Many lens designs have been proposed that go beyond the diffraction limit in some way, but there are constraints and obstacles involved in realizing each of them.

Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.

Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness.

Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses.

Some types of safety glasses are used to protect against visible and near-visible light or radiation.

Glasses are worn for eye protection in some sports, such as squash.

Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports.

Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.

A simple lens consists of a single piece of transparent material, while a consists of several simple lenses (elements), usually arranged along a common axis.

Lenses are made from materials such as glass or plastic, and are ground and polished or moulded to a desired shape.

A lens can focus light to form an image, unlike a prism, which refracts light without focusing.

Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses.

Glory is the ninth studio album by American singer Britney Spears.

It was released on August 26, 2016, through RCA Records.

She also renewed her record deal with RCA Records.

Spears began work on the album in 2014; lacking a deadline for completion, she continued work into 2015 and 2016, which—according to Spears—provided her the opportunity to create one of her favorite albums in her catalogue.
