Floaters And Losing The Clarity Of Youthful Vision
“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.

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.

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.
