Blackholes for the Blind   (0)  [vote for, against]
Electromagnetic blackholes created around the cornea for the blind.

Surgically installed contacts located around the eye made of meta-materials

"Each strip takes the form of a circuit board etched with intricate structures whose characteristics change progressively from one strip to the next, so that the permittivity varies smoothly.

The outer 40 strips make up the shell and the inner 20 strips make up the absorber.

"When the incident electromagnetic wave hits the device, the wave will be trapped and guided in the shell region towards the core of the black hole, and will then be absorbed by the core,"

These contacts aid deficient cornea in refracting visible light if not completely replacing it. The lens in the eye uses this light as it normally would there. However the lens can also be superseded by the black hole to redress any issues with it as well.

I don't get this. Is it meant to replace glasses/contact lenses in helping the wearer to focus? Are the quotes quoted from somewhere?

But woah! I forgot to say welcome to the HalfBakery! Watch out for the locals. And under no circumstances accept any offers of custard.

//paras 2,3,4 copied from article. // That's why I asked about the quote marks. Quoting is fine, I think. But I don't understand the idea's purpose.

Many forms of blindness are caused by the eyes inability to refract light. A blackhole sucks in light.

So, what do these do that is different from a lens?

Could you name a few?

"I dropped my contact lens...and now it's orbiting the Earths core."

The article mentions a "desktop black hole".

Sadly nothing to do with the cosmological buggers; an application of a 'meta-material', which etymology I don't understand.
