Bionic lens promises SUPERHUMAN sight three times better than 20/20

From glasses to standard lenses and even lasers, there are many ways people can restore or correct their vision.
But the latest so-called 'bionic' lens promises to not only restore sight, it claims it can boost it to three times better than 20/20.
And surgery to insert the lens takes just eight minutes, with sight being restored in seconds.
The Ocumetic Bionic Lens (pictured) was created by Dr Garth Webb. He claims surgery to implant the lens is as 'painless and gentle' as cataract surgery and restores sight within 10 seconds. Although he hasn't revealed the intricacies of the technology, he did say it created vision three times better than 20/20

Visual acuity - or the ability to see fine spatial details - is typically measured with a Snellen chart used by optometrists globally.

In theory, this means Dr Webb's lenses could create 20/0 vision, at which point the wearer could see letters when stood at 20ft that a normal person could see with the letters directly in front of their eyes - although Dr Webb has not categorised it in this way.
Elsewhere it is made of 'inert biocompatible polymeric materials; that do not cause biophysical changes within the eye.
Dr Webb has not revealed the intricacies of the technology behind the lens and MailOnline has contacted him for more information.
The chart displays letters that get progressively smaller in size.
The benchmark, and vision that is considered healthy and 'normal', is classified as 20/20.
This means a person can see the same line of letters when stood at a distance of 20ft compared with what a 'normal' person sees at the same distance.
A basis for 'normal' was determined using a large database of test results.
By comparison, 20/40 vision means the test subject sees at 20ft what a 'normal' person sees at 40ft.
Legal blindness is categorised as 20/200. On the opposite scale, 20/15 offers enhanced vision.

In July 2013 researchers from San Diego and Switzerland fitted a traditional contact lens with a magnifying ring which, when worn with a pair of Samsung 3D glasses, could magnify scenes by 2.8 times.

The vision created by Dr Webb's lenses has been dubbed 'super sight' because its more powerful than the average person's sight. Superhuman vision is common in science fiction films and comics such as Superman (Henry Cavil in Man of Steel is pictured)
The lens-glasses combination was designed to help restore the sight of people suffering from age-related macular degeneration, or blindness.
The 8mm contact lenses were fitted with a 1.17mm magnifying ring around the edge and small aluminium mirrors were fitted into this magnifying ring.
These mirrors bounced the light from objects in front of the wearer approximately four times around this ring before sending the image to the retina.
By the time this image hit the retina it appeared magnified by almost three times.
When the lenses are being worn in 'ordinary mode' this magnified image is blocked by polarising filters fitted to a pair of modified Samsung 3D glasses.
Researchers recently developed lenses that give the wearer telescopic vision, designed to restore sight in blind people. The front and back of the lens are shown at (a) and (b). Picture (c) shows the lens on an optomechanical eye. The lenses are worn with 3D glasses and can magnify images when unblocked (e)
Elsewhere, iOptik announced at last year's CES that it had developed contact lenses that allow the wearer to see high-definition virtual screens (pictured). In particular, the system lets them see projected digital information, such as driving directions and video calls
To switch to 'telescopic mode', the wearer can change these filters so that the only light that hits their retina is the light created by the magnified process.
Elsewhere, iOptik announced at last year's CES it had developed contact lenses that allow the wearer to see high-definition virtual screens.
In particular, the system lets them see projected digital information, such as driving directions and video calls.
The tiny 'screens', which are the invention of Washington-based group Innovega, sit directly on a users' eyeballs and work with a pair of lightweight glasses.
Google is also working on 'smart lenses' that contain a control circuit, an image capture component and an image sensor.
The system can be wirelessly linked to a mobile phone for data access and to issue commands via audio, although it is unclear if the lens would be powered wirelessly or have a wired link to a battery.
