Who invented the contact lenses? The artistic history behind the lens

Leonardo da Vinci's famous artist was the first person to create contact lenses in 1508, but the French philosopher, Rene Descartes, used sunglasses to use contact lenses.

Contact lenses are located on the cornea for eye correction, therapeutic and cosmetic purposes. The contact lens often has the same benefits as a thick spectacle, the difference between the two correction fields because the contact lenses are light and visibly unclean.

About one hundred and twenty-five thousand people around the world with contact lenses. The lenses are most people in the United States and Japan. Twenty-eight-thirty-eight million American sports contacts, while the lens compiles thirteen million people in Japan.

Leonardo da Vinci is commonly known as the inventor of contact lenses. Da Vinci first proposed a method for testing the strength of the cornea by fitting his eyes into a bowl of water in his 1508 philosophical work. Manuel D. Leo showed interest in how the eye fit to certain elements influenced. Da Vinci did not care to use contact lenses in addition to correctional vision, as optical innovation came from the French philosopher and mathematician Rene Descartes. In 1636, Descartes suggested that a glass tube be filled with some liquid and put the tube on the cornea. According to the original plan, the bottom of the glass tube was designed so that the vision was correct – the design came to a standstill when it was considered as if it could not have been blinking.

In 1801, Thomas Young, a British scientist, developed an "eye cup" liquid that is the world's day predecessor to modern day contact lenses. Like the relationship developed by Da Vinci, Young's contact lenses were originally not designed for optical correction. In 1887 Adolf Eugen Fick made the first successful correction contact lenses

Contact lenses contain three basic functions, corrective contact lenses, therapeutic contact lenses and cosmetic contact lenses. Visually-behaved contact lenses were the first in the family of visionary caps for correct defective vision. These contacts were asked to improve optical disorders that can not be corrected by glasses, including non-inflammatory keratoconus and aniseiconia disorders caused by uneven meshes. Corrective contact lenses are also prescribed for optical conditions, such as close-ups (medical myopia), visual hypermetropia and irregular corneas characterized by astigmatism.

Therapeutic contact lenses or soft contact lenses are used to treat ophthalmic disorders that are subject to dry eyes, corneal ulcers, eye erosion and bullous keratopathy. Therapeutic contacts were compared with "lens lenses" due to their protected properties of refractive disorders of the eye.

Cosmetic contact lenses are used to change eye appearance. Elegant cosmetic relationships often cause color changes in your eyes. The American Food and Drug Administration classifies cosmetic contact lenses as "decorative links". Costumes and patterns associated with cosmetic lenses were linked to blurred vision and optical firing. Types of theatrical and scleralized cosmetic contact lenses
