18 th March is a World Eyeglasses Day
Eyeglasses are a tool used to correct vision defects or protect the eyes from harmful rays. They typically consist of two circular, oval, or differently shaped lenses made of glass or plastic, which are mounted in a frame with openings for the lenses. The frame is designed to sit comfortably on the nose, with arms extending towards the ears to hold the glasses in place. When the lenses are fitted correctly, they provide the necessary vision correction.
History
Greek and Roman authors mention the use of water-filled glass vessels to magnify objects, as described by Claudius Ptolemy in 150 AD. In ancient times, religious scholars used thick lenses while reading and copying manuscripts. In 1282, a clergyman named Nicholas Bullett used eyeglasses to sign a contract. Roger Bacon is credited with the invention of eyeglasses, as he suggested that transparent crystals or glass could help people with poor eyesight. However, Marco Polo recorded that the Chinese were using lenses for vision correction around 1270.
Concave lenses became popular in the 15th century, benefiting those with nearsightedness. Eyeglasses evolved significantly over time. Lenses were mounted in frames, and in 1827–1830, Edward Scarlett introduced the concept of adding temples (arms) to secure them over the ears. By 1749, telescope-like glasses were in use, and in 1806, single-lens eyewear became common. The use of double-lens glasses with a spring mechanism was introduced in 1840.
The idea of contact lenses was first proposed by Sir John Herschel in 1845. German scientist Müller successfully demonstrated the protective use of contact lenses for diseased corneas. Swiss physician Eugène Fick later coined the term “contact lenses.”
