The selected readings for this week cover a variety
of innovations in a wide array of fields around the globe, ranging from
Education to Energy. One of these particularly
struck a chord with me: the self-adjusting eyeglasses presented in Honor
Whiteman’s article “Self-Adjustable Eyeglasses: How One Man's Vision Is Helping
Others to See Better.”
Firstly, I was struck by the simplicity of the
glasses. As stated, the concept of self-adjusting
glasses was first proposed in 1879, but was not actually realized until 1985,
when Joshua Silver was asked if he could create an adjustable focus lens. “My
initial response was ‘no,’… Then I said, ‘oh yes,’ and I made one that afternoon,
and I've still got it.”[1] It
only took someone questioning the way things were traditionally done to create
a product that has the potential to change countless lives. The glasses, called
Adspecs, as well as more recent models, are easily produced; the only roadblock
to making them completely accessible to all in developing countries is the cost
of production (and, therefore, the price). Through continued testing, the
glasses are becoming less and less expensive to produce, but are still above
Silver’s stated goal of $1 per pair.[2]
As I continued reading, I could not help thinking of
my own family. Just three years ago, my father’s eyesight deteriorated so much
that he had to undergo the Lasik procedure. Though successful at first, his
vision has once again quickly deteriorated since then, almost as if he had
never undergone the pricey surgery. I know that my family would have
appreciated a low-cost alternative to Lasik, especially considering its
volatile results – which led me to consider accessibility of the self-adjusting
glasses to consumers in countries like the US. What would be the consequences
to tapping into a market of individuals who often do have access to optometric
care, with regards to price and accessibility to the product in developing
countries? And, as Whiteman asks in his article, “Would self-adjustable eyewear
work in such countries? And would opticians be willing to sell such a product?”[3]
It’s interesting to see what technologies have
emerged since the unveiling and implementation of these glasses, some of which
may be more fitting for a market of individuals in developed countries. One
example is Deep Optics’ self-adjusting lens, which would use the same basic
idea as Silver’s lenses (a liquid layer between lenses which shifts to refocus
the viewer’s eyes), but would adjust focus nearly automatically thanks to an
internal processor.[4]
Though this is only a prototype for now, similar products could ultimately open
self-adjusting lenses to a market that can afford more than just the bare
basics. In fact, similar products, such as dial-adjustable glasses, are already
available in stores such as Walmart and on sites like eBay for an affordable price.
For example, Walmart offers “Adlens Adjustables Unisex Variable Focus Eyewear”
for only $23.97.[5]
It may not be anywhere near Silver’s proposed $1 mark, but it’s a start.
