Researchers at MIT have developed a method of using a basic cellphone coupled with a cheap and simple plastic device clipped onto the screen to estimate refractive errors and focal range of eyes.
Because of its simplicity, and the fact that soon just about everyone will have access to a mobile phone, eye exams may become available to the whole world at little to no cost. Read more »

“Will you grab that spider web?” my grandmother said abruptly. We were sitting on an old bench overlooking the river. It was September. I had sprung her from the assisted living home earlier that day.
“Which spider web are you talking about, Gram?” I asked her. My eyes were sleepily watching the timeless flow of the big river, the eddies and swirls along the banks, and the gracefully bending boughs of the old oak trees as they waltzed with the wind.
“There to the left!” she said with certainty, reaching her bony hand into the sky and grasping at thin air. “Get it, will you?”
I looked again but there was nothing. I knew that my grandmother’s mind had developed a little static among the signals, a few crackling wires in the electric grid of her brain, and I figured that her eyes were playing tricks on her.
“I don’t see it, Gram. What does it look like?”
She seemed a little disappointed that I did not share her perception. “It’s feathery, and it’s drifting just over the river. It’s actually quite pretty.” Read more »

PaPaLaB Co Ltd, a Japanese firm, has announced their development of the “YC-3300,” a camera they claim can capture the exact same colors as seen by the human eye. The camera is designed for archiving and medical applications. While cameras with similar technology currently exist, they are too large and expensive to be practical. The YC-3300 is currently priced at $140,477, with more affordable models in the pipeline.
Technology like this will be crucial with cameras in medicine taking an ever larger role in research, education, and diagnosis.

Even though we intuitively think that a particular color looks the same to different people, researchers from The University of Chicago and Vanderbilt University have uncovered that the brain plays a critical role in color perception. The brain actually assigns colors to objects and with a bit of tinkering one can fool the brain to assign the wrong color to an object being viewed. Read more »

It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…

Book Review: Is Empathy Learned By Faking It Till It’s Real?
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
The Spirit Of The Place: Samuel Shem’s New Book May Depress You
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
Eat To Save Your Life: Another Half-True Diet Book
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
