Interesting truth about contact lenses
The idea of a contact lenses like a first visual support begins to seem like a great idea in 1508.
Like many ideas about revolution and transition of this time, it is the intellectual property of inventing Leonardo da Vinci boss.
Da Vinci describes a direct method that changes the corneal strength of vision by engulfing the head in a bowl of water, or by wearing some glass hemisphere filled with water on the eyes.
However, this has been shown to be unrealistic as many other inventions of Da Vinci (E.g. Helicopter), due to the age he lives.
Develop contact lenses.
Further down to 1636, the French philosopher René Descartes proposed the idea of a liquid glass tube filled with liquids for direct contact with the cornea.
The protruding head of this tube is to include glass and with exact shapes.
This is also proven to be unrealistic, like its ungainly size and shape prevents people from blinking.
Quick transfer to 1887, Germany, where German glass blowers F.e.
A year later, in 1888, German ophthalmologist Adolf Fick - working from the findings of Muller - built and equipped with first contact lenses from Blown Glass.
Although uncomfortable, and can only be worn in a few hours at a time when it is worn on the entire eye, this is a real breakthrough in contact lenses technology.
In 1949, the first pressure glass was developed and soon became popular, becoming a series of compelling a series in the 1960s.
Modern contact lenses.
Modern contact lens works by resting on the corneal of the wearer, the outer outer surface of the eye.
The lenses are kept in the main position by pasting into the tear film covering the front of the eye, but the second is the pressure caused by the eyelids caused by the blink of an eye.
When the person wears the light, their eyelids surfed on the lens surface, thus moving a bit.
This movement allows the tears of the wearer to provide the necessary lubrication for the cornea and also helps to clean any debris between the cornea and contact lenses.
Contact lens function.
Contact lenses There are two main functions: medical use and aesthetic use.
However, due to lightweight optical lenses and sometimes serious can bring, all kinds o
In terms of medically, contact lenses are often used to fix visual disorders such as myopia, hyperopia, astigmatism and reading problems.
These conditions are caused by light not properly focused on the retina, causing blurred vision or me
When placed on the cornea, an exposed lens acts as an original optical element to eye in the light picking up.
These optics combine with optical words
Contact lenses in the movie.
Due to how contact lenses can be used to significantly change the appearance of an individual's eyes, they see a widely used in the film industry and TV.
Some apps that are more noticeable about contact lenses in movies are red blood eyes o
Contact lenses are also widely used on Saga of Star Wars as well as in Riddick films (Pitch Black, Riddick Chronicles).
Contact lenses are
Future concept for contact lenses.
One in the future can use contact lenses of bionic contact lenses - a concept unlike Google glasses.
This type of dedicated contact lens is currently under development, followed by a prototype in Seattle, USA.
The lens itself is made up of biological safety organic materials and has electronic circuits built from a metal layer of only a few nanometers.
Currently, the device can only operate in a few cents with raw wireless batteries and only one pixel screen.
However, this is just another step for contact lenses that can bring the rudimentary idea of Da Vinci and push it into the future of Mass-Media.
So those who know, give it a decade (perhaps less about the level of technology quickly moving these days) and we all can read extremely through our bionic contact lenses
