sunglasses are important for a great
number of purposes. they aid in
professions involving glare, are good for
protecting your eyes from uv, people
who
have sensitive eyes can also wear them in
order to protect their eyes.
unfortunately, wearing sunglasses in a
social setting can make
it difficult for
people to catch some of the more subtle
body language inherent in eye
movement.
rolling your eyes, or motioning to
something with them, even maintaining a
piercing glare all become difficult to
achieve when wearing lenses with any
useful level of tint. it is also difficult for
people to see the direction of you're
gaze,
to the point where they're never sure
whether you're looking at them or not.
in order to rectify this situation, i feel
that
a type of sunglasses that have an image
of
your eye projected onto the outside
surface can go a long way.
there are a number of ways that this can
be done. this first of which is turning the
lense of the glasses into an lcd with a
pair
of small video cameras on the inside
frames that create the image on the
screens.
this can also be achieved with a
sophisticated assembly of eye tracking
equipment set up to tell an arm on the
frame of the lenses where to hold a
translucent plastic cutout of you're eye
relative to the screen. while this method
would involve a bit off excess weight
sitting on your nose, it would have the
added benefit of keeping other people
from wanting to borrow your sunglasses.
