Title, vision simulations.
-
People with visual impairments
using assistive devices.
-
For people with
normal sight, it can
-
be difficult to fully comprehend
the experience of the visually
-
impaired.
-
One frequent comment from
those with vision loss
-
is if you could see
what I see, you'd
-
understand what
I'm going through.
-
In this section, we have
created a series of simulations
-
for the most common
causes of vision loss.
-
We hope that by
viewing them, you
-
will gain a better
appreciation for vision loss
-
and improve your ability
to assist and communicate
-
with those who have low vision.
-
Title, macular degeneration.
-
A blurred image with
dark spot in the center.
-
Macular degeneration
is the leading cause
-
of vision loss
among older people.
-
It is a condition that affects
the center portion of the eye.
-
That's the part responsible
for central vision
-
and seeing detail.
-
Title, cataracts.
-
A sharp, focused
image becomes blurred.
-
A cataract is a cloudy area that
forms in the lens of the eye.
-
Cataracts cause an overall
blurring and haziness of vision.
-
If you have cataracts, it often
appears as if everything is out
-
of focus.
-
People with cataracts tend to be
very sensitive to bright light
-
and glare.
-
Title, glaucoma,
retinitis pigmentosa.
-
A blurred image with a sharply
focused area in the center.
-
While very different conditions,
both glaucoma and retinitis
-
pigmentosa result in a
loss of peripheral vision,
-
often described
as tunnel vision.
-
People with a certain
type of glaucoma
-
can also experience nausea,
headaches, and halos
-
around bright lights.
-
Title, diabetic retinopathy.
-
A blurred image with
dark spots throughout.
-
When diabetes damages the tiny
blood vessels in the retina,
-
this condition results
in overall blurred vision
-
and blind spots from
bleeding in the eye.
-
The conditions can
produce patchwork images
-
where portions are
completely blocked out.
-
Title, hemianopsia,
stroke related blindness.
-
Image of a
refrigerator, left side
-
blurred, right side focused.
-
The result of a cerebral
stroke, brain tumor or trauma,
-
hemianopsia is the loss of
vision in half the visual field.
-
Look at how difficult it
is to see the water and ice
-
dispenser on the left.
-
People with this
condition can benefit
-
from learning new techniques
to scan their environment.
