Knowing about people’s health
through eyes has always been useful for doctors. Moreover, people often say
that eyes are the window to the soul. It seems that Professor Jin Zhang, from University of Western Ontario, has taken that into account, he
created new contact lenses that might be a release for diabetic patients. The
lenses are made by embedded nano-particles into hydrogel. The great part in
this is that the nano-particles react to the blood found in the tears.
According to the level of sugar in the blood, the lenses change colors, warning
the wearer that his or her levels of glucose have changed.
Thank
to this new device, diabetic people will have the opportunity to avoid the uncomfortable process of self-monitoring and taking blood samples throughout
the day. Regarding this, professor Zhang points out that “There
is a need for a non-invasive measure to detect the levels of glucose, instead
of taking a blood sample,”
Personally, I think that the device is great since it improves people’s
quality of life. The only problem that can come up
with the lenses is the cost. Maybe, people with low incomes will have to wait
for months or even years until the can get their pair of contact lenses.
In
this video you can learn more about contact lenses technology in general. And
from minute 1:44 you will find specific information about this topic.
