Aristophanes
Aristophanes (Ἀριστοφάνης,; c. 446 – c. 386 BC), son of Philippus, of the deme Kydathenaion (Cydathenaeum), was a comic playwright of ancient Athens.

Burning glass
A burning glass or burning lens is a large convex lens that can concentrate the sun's rays onto a small area, heating up the area and thus resulting in ignition of the exposed surface.

Charles S. Hastings
Charles Sheldon Hastings (November 27, 1848 – January 31, 1932) was an American physicist known for his work in optics.

Coddington magnifier
A Coddington magnifier is a magnifying glass consisting of a single very thick lens with a central deep groove diaphragm at the equator, thus limiting the rays to those close to the axis, which again minimizes spherical aberration.

Defocus aberration
In optics, defocus is the aberration in which an image is simply out of focus.

Detective fiction
Detective fiction is a subgenre of crime fiction and mystery fiction in which an investigator or a detective—either professional, amateur or retired—investigates a crime, often murder.

Dioptre
A dioptre (British spelling) or diopter (American spelling) is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres.

Focal length
The focal length of an optical system is a measure of how strongly the system converges or diverges light.

Focus (optics)
In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge.

Fresnel lens
A Fresnel lens is a type of compact lens originally developed by French physicist Augustin-Jean Fresnel for lighthouses.

Glasses
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.

Graphoscope
A graphoscope was a 19th-century device used in parlors in order to enhance the viewing of photographs and text.

Image
An image (from imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

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

Loupe
A loupe is a simple, small magnification device used to see small details more closely.

Macro photography
Macro photography (or photomacrography or macrography, and sometimes macrophotography), is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size (though macrophotography technically refers to the art of making very large photographs).

Magnification
Magnification is the process of enlarging the appearance, not physical size, of something.

Microscope
A microscope (from the μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye.

Optical aberration
Aberration in optics refers to a defect in a lens such that light is not focused to a point, but is spread out over some region of space, and hence an image formed by a lens with aberration is blurred or distorted, with the nature of the distortion depending on the type of aberration.

Optical power
Optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light.

Pliny the Elder
Pliny the Elder (born Gaius Plinius Secundus, AD 23–79) was a Roman author, naturalist and natural philosopher, a naval and army commander of the early Roman Empire, and friend of emperor Vespasian.

Presbyopia
Presbyopia is a condition associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects.

Reading stone
A reading stone was an approximately hemispherical lens that was placed on top of text to magnify the letters so that people with presbyopia could read it more easily.

Roger Bacon
Roger Bacon (Rogerus or Rogerius Baconus, Baconis, also Rogerus), also known by the scholastic accolade Doctor, was an English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empiricism.

Spherical aberration
Spherical aberration is an optical effect observed in an optical device (lens, mirror, etc.) that occurs due to the increased refraction of light rays when they strike a lens or a reflection of light rays when they strike a mirror near its edge, in comparison with those that strike close to the centre.
