3. The Bionic Goggles are
high-tech glasses that
allow the legally
blind to see.
It also
help those
who are normally
confined to their homes
to navigate shopping centers or
simply walk to the corner shop and
read bus numbers. smart spectacles use tiny cameras and
a pocket computer to alert wearers to objects and people
ahead.

4. The founder of this technology is a Canadian
engineer Conrad Lewis. He did it for his two
sisters, who were legally blind due to
Stargardt’s Disease.
There was nothing that could be done
medically, but Conrad believed he could
develop an engineering solution that would
restore their sight.
Lewis started working for this in 2007,
beginning his quest with a small team of 20
researchers and engineering developers.
Now, he is profoundly known as the founder of the Ottawa-based
company , eSight Corporation.
His idea and hard work are now helping many legally blind people
to see.

5. According to the World Health Organization (Arditi & Rosenthal,1998),
when the best-corrected vision in the better eye is in the following ranges,
it is considered:
Sl. No. Range of Vision Description
1. 20/30 to 20/60 near-normal vision or mild vision loss
2. 20/70 to 20/160 moderate visual impairment, or moderate low vision
3. 20/200 to 20/400 severe visual impairment, or severe low vision
4. 20/500 to 20/1000 profound visual impairment, or profound low vision
5. Below 20/1000 near-total visual impairment, or near total blindness
6. No light perception total visual impairment, or total blindness
Legal blindness is the inability to achieve better than 20/200 vision with
spectacles on –even with visual aids, a legally blind person could not see
from 20 feet an object which someone with perfect vision could see from
200 feet. Some legally blind people can see a small amount, but their eyes
do not pick up enough for their brains to recognize what is being seen, and
it is these people whose lives can be turned around with these invention.

6.  Device has a video camera mounted on the frame of the glasses.
 Software projects images of nearby objects to the see-through displays
 The glasses don't replace lost vision but assist with spatial awareness

8. Image Processing
Image captured by the camera, processed for magnification,
edge enhancement and contrast enhancement and projected
from the video goggles onto the parafoveal region of the
retina. Additional smart processing for dynamic
magnification in the fovea is enabled by eye tracking.

10. Iain Cairns, 43, tried out the glasses in
Oxford's Covered Market. He was diagnosed
with the inherited eye condition
choroideremia at around the age of 12. On
having the glasses fitted, Iain reacted: 'Ooh, I
can … I can see your face. It's, er, like
suddenly going into … Like the Lord of the
Rings when he puts the ring on. And sees
things in a new way … That tablecloth is
looking lovely. It's getting the pattern of the
tablecloth … It's like I’ve wandered into an
80s pop video.
Everyone has cool A-ha drawings round them. . It's now much more of a
scene with several people in.

11. Lyn Oliver, 70, of Faringdon in Oxfordshire has a
guide dog, Jess, to help her get around. She was
diagnosed with retinitis pigmentosa in her early
20s, an eye disease which gradually leads to loss of
vision and blindness.
Lyn has tried out the bionic glasses and describes
how they could help when out with her guide dog:
'If Jess stops, the glasses can tell me if she's
stopped because there's a kerb, there's something
on the floor or it's road works, and it'll give me a
sense of which way she may go around the
obstacle.' Lyn relates how on one occasion, when
she was without a guide dog for six months last
year and just using a cane, she walked into a car.
'Some people insist on parking on the pavement,
and then swear at you because you've walked into
their Precious car. There was just too much traffic
noise for me to detect it there. With the glasses on,
I would have seen the car.’

12.  Blindness and visual impairment affect people in different degrees. moderate visual
impairment and severe visual impairment can be coupled together under “low vision”.
People who suffer from low vision may find everyday activities such as reading,
writing, cooking, and shopping to be challenging even after regular corrective lenses.
 This glasses help visually impaired to “see” better, using technology normally found in
smatphones and video game accessories, these high-tech specs make use of camera, face
tracking software and sensors.
 Different colors could represent different things, such as people or objects whereas
brightness could convey proximity. This glasses also provide audio feedback played
through an earpiece.
 These glasses in short allowed people to be more independent.

13. Future Promises
 Currently, the team is working to expand the capabilities of its eyewear.
In its current form, the device already addresses a large range of vision
problems, but software enhancements will extend that even further.
 Further advancement of the semitransparent video goggles with low
weight and ergonomic design will minimize the social awkwardness of
the electronic eyewear.
 Higher resolution, high brightness and contrast would allow
comfortable viewing.
 Advanced image processing, and especially image recognition, are
other very promising directions of future research.
 Advancements in the field of three-dimensional cameras will help
encode depth information and provide additional warnings about the
obstacles.
 Similar algorithms for image simplification and enhanced scarcity
should help with optical approaches to restoration of sight. Better
understanding of pathways of retinal and cortical processing of
artificial vision will help to optimize the algorithms of image
presentation in these vision restoration approaches.
