However, Ancient Greek and Roman science did not understand refraction (how light is bent through a lens) and did not use lenses to correct short sight (they thought the eye sent out beams, rather than receiving light waves). ... As lens making became more accurate, artists began to realise the possibilities for using a lens to help with making ...
The History of Lenses. The use of lenses dates back thousands of years, with early civilizations discovering the basic principles of optics and refraction. Ancient Beginnings: Egypt and Mesopotamia: Some of the earliest lenses, made of polished crystals, have been found in ancient Egyptian and Mesopotamian sites, dating back to around 700 BC ...
It has even been suggested that a piece of Greek pottery discovered dating back to 4th century BC depicts a man using an early telescope and that ancient people were able to connect two lenses inside a simple tube to make an early, crude telescope. However, making lenses and a telescope useful for astronomy purposes requires a level of ...
The earliest applications of optics most likely began with the development of lenses in ancient Egypt and Mesopotamia. The earliest known lenses, made of polished glass, often quartz, date as early as 700 BC. C., like the Nimrud lens, discovered in Assyria. Water-filled glass spheres used as lenses in ancient Rome and ancient Greece are also known.
Few other advances were made in optics until after 1000 AD. However, the Arab scholar Alhazan, a.k.a. Abu Ali Hasan Ibn al-Haitham, conducted the first serious study of lenses in Basra (Iraq). He studied refraction in lenses, disproving Ptolemy's law of refraction, and also carried out research on reflections from spherical and parabolic mirrors.
The last lens was estimated to have a focal length of 150 mm. Of the "lenses" recently published, the vast major-ity have a diameter between 23 and 25 mm. Signifi-cantly, one of the "lenses;' with a diameter of 54 mm and maximum thickness of 6 mm, bears a 9-mm hole in its center.14 D6rpfeld, who dated the objects to
lenses were also discovered in the ancient city of Tanis, Egypt, in the remains of a house belonging to an artist. They are dated to around h A focal length of 15 mm is given in 7, but this must ...
The field of optics has served an essential role in the advancement of science and technology, with evidence of lens production dating back to the ancient Egyptians as early as 2000 BC [1]. Modern ...

Most lenses, though, were probably magnifiers for authenticating seals and for carving gems. (Sines, George, and Sakellarakis, Yannis A.; "Lenses in Antiquity," American Journal of Archaeology, 91:191, 1987.) Comment. We wonder if any ancient Greeks ever put two of these lenses together to make a telescope.
Finally after more than 2 thousand years, discoveries in many fields of science enabled engineers and inventors to start testing “modern optics”, which focuses on the research of brand new areas such as wave optics and quantum optics. ... One of the most famous examples of those original lenses is Nimrud lens. Created in the ancient Assyria ...
It is more powerful and of better quality than the Nimrud lens. Also, the Roman writers Pliny and Seneca both referred to a lens used by an engraver in Pompeii. It could be that the science of optics is a lot older than we have believed. But the Nimrud crystal could just as well have been an item of jewelry or an amulet.
Ancient optics experiments laid the groundwork for modern scientific methods, illustrating humanity’s enduring quest to understand the nature of light. Investigating phenomena such as reflection and refraction, these early inquiries were pivotal in shaping optical science.
The early history of optical lenses is poorly defined. Lens-like objects were used for jewelry or decorations for thousands of years, and technology necessary to make lenses was available. In antiquity, a number of activities would have benefited from image size enhancement, and a few lens-like obje …
Discovered in 750 BC, Nimrud Lens is considered to be the oldest lens artefact. It is believed to have been used as a magnifying glass to read, to concentrate sunrays to start fires or as a decorative piece. It has a focal length which is roughly 12 centimetres (equal to a 3x magnifying glass). The image is from Wikimedia Commons and is ...

A. Sutherland - AncientPages.com - The Nimrud lens is 3,000-year-old object that could re-write the history of science. Although the telescope was officially invented in the 16th century, it is possible that ancient Assyrian astronomers used the so-called Nimrud lens that allowed them to watch the skies nearly three thousand years earlier.
