Color Blind? These Lenses May Help

vivid-s

Apparently, Encroma lenses are not a cure for color blindness, but for some individuals, they offer some help by enhancing colors.

From their site – With the EnChroma lens, colors appear brighter and more saturated. People report that their color discrimination is faster and more accurate, they are able to see more vibrant colors. They are more likely to notice objects that are differentiated against a background based on color (such as a flower against background of leaves), whereas without the lens those objects would have been overlooked.

Camera That Sees Cancer Is In Development, May Be Adapted To Cellphones

lensAccording to the University of Queensland –

Mantis shrimp eyes are inspiring the design of new cameras that can detect a variety of cancers and visualise brain activity. University of Queensland research has found that the shrimp’s compound eyes are superbly tuned to detect polarised light, providing a streamlined framework for technology to mimic. Professor Justin Marshall, from the Queensland Brain Institute at UQ, said cancerous tissue reflected polarised light differently to surrounding healthy tissue.

Vantablack – A Material Too Black To See

vantablack-sAccording to The Independent –

A British company has produced a “strange, alien” material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the “super black” coating made of carbon nanotubes – each 10,000 times thinner than a human hair – is an odd experience. It is so dark that the human eye cannot understand what it is seeing. Shapes and contours are lost, leaving nothing but an apparent abyss. Actual applications are more serious, enabling astronomical cameras, telescopes and infrared scanning systems to function more effectively. Then there are the military uses that the material’s maker, Surrey NanoSystems, is not allowed to discuss.

Soap Bubble 3D Display Screen

According to BBC –

Viewers may soon be able to watch films on soap bubbles – after researchers developed a technology to project images on a screen made of soap film. An international team produced a display that uses ultrasonic sound waves to alter film’s properties and create either a flat or a 3D image. The bubble mixture is more complex than the one sold in stores for children, but soap is still the main ingredient. The team says the display is the world’s thinnest transparent screen.

Trillion Frames Per Second Camera Is Able To Capture Light Waves

According to BBC –

A camera capable of visualising the movement of light has been unveiled by a team of scientists in the US. The equipment captures images at a rate of roughly a trillion frames per second – or about 40 billion times faster than a UK television camera. Direct recording of light is impossible at that speed, so the camera takes millions of repeated scans to recreate each image. The team said the technique could be used to understand ultrafast processes. The process has been dubbed femto-photography and has been detailed on the Massachusetts Institute of Technology’s Media Lab’s website. “There’s nothing in the universe that looks fast to this camera,” said Andrea Velten, one of the researchers involved in the project.
