The document discusses a presentation about bionic eyes. It begins with an introduction to bionic eyes and their purpose to restore vision for blind individuals. It then explains that bionic eyes work by using a camera and microchip implants to convert images into electrical signals that the brain can interpret as vision. The presentation covers advantages like restored visual tasks for patients, disadvantages like high costs and risks, and a conclusion that bionic devices may not fully restore vision but can help blind people lead more independent lives.

4. Introduction :
 Eye is the most sensitive and most important part of a
human beings body
 Some people are born blind and some people get
build due to some eye defects or partially loose their
vision
 India has largest blind population in the world which
is nearly about 15 million people
 “The world only exists in you EYES.you can make it
as BIG or as SMALL as you want.”
 - F.Scott fitzerald

5. What is bionic eye?
 Derivation of the word “Bionic (bio+electronic )
 Bionic eye,is an experiment visual device intended to restore
functional vision in those suffering blindness.
 Bio electronic eye
 Electronic device which replaces the functionality of a part or
whole of the eye.
 Bionic eye devices are developed to restore a sense of vision to
people with retinitis pigmentors and age-related macular
degeneration
“We are entering a bionic era where we actually are beginning to
see technology that’s sophisticated enough to emulate key
physiological functions.”
- Hugh Herr.

6. Working of bionic eye :
 The bionic vision system consists of a camera,
attached to a pair of glasses, which transmits high
frequency radio signals to a microchip implanted in
the eye.
 Electrodes on the implanted chip convert these signals
into electrical impulses to stimulate cells in the retina
that connect to the optic nerve
 These impulses are then passed down along the optic
nerve to the vision processing centers of the
brain,where they are interpreted as an image

9. Aim of the bionic eye
 The main aim of artificial vision is to restore some degree
of sight to the profoundly blind
 Since blindness can result from defects at many different
points along the visual pathway.there are accordingly a
wide variety of proposed models for an artificial eye.
 The earliest stage of visual processing in the
transudation of light into electrical signals by the
photoreceptors
 Biohybrid implant a device that incorporates living cells
with man- made elements .
“Your eyes show the strength of your soul.”

10. Advantages :
 Ability to perform visual tasks demonstrated in many patients
 Upgradable external hardware and software to benefit form future
innovations
 It can be easily implanted
 There is no necessity to suffer from long and short sights
 It helps to correct the vision
 No longer has limited access
 The brain has an amazing ability to adapt to new input and improve his or
her understanding of what is being seen via an artificial vision system
. A camera is the save button for the minds eye

11. Disadvantages :
 It will not be helpful for glaucoma patients
 Australian one is still being researched
 Both eyes has research cost in the million of dollars
 American one doesn’t correct vision to 100%
 Creating an artificial replacement for these is a
risky task
 It is difficult to acquire this technology by common
man
the eye of a human being is a microscope which
makes the world seem bigger than it really is.
- khalil gibran

12. Conclusion:
 Bionic devices are being developed to do more
than replace defective parts
 Be may not restore this vision fully but we can
help them at least to find the air way recognise
faces read books distinguish between object
such as cups and plates above all lead and
independent life
