Do It Yourself Eyeglasses Use Water To Let Users Make Their Own Prescription.

Josh Silver is on a quest to make the world’s poor see. A professor of physics at Oxford University, Silver was idly discussing optical lenses with a colleague, wondering whether they might be adjusted without the need for expensive specialist equipment, when the lightbulb of inspiration first flickered above his head.

What if it were possible, he thought, to make a pair of glasses which, instead of requiring an optician, could be “tuned” by the wearer to correct his or her own vision? Might it be possible to bring affordable glasses to millions who would never otherwise have them?

More than two decades after posing that question, Silver now feels he has the answer. The British inventor has embarked on a quest that is breathtakingly ambitious, but which he insists is achievable… to offer glasses to a billion of the world’s poorest people by 2020.

Silver has devised a pair of glasses which rely on the principle that the fatter a lens the more powerful it becomes. Inside the device’s tough plastic lenses are two clear circular sacs filled with fluid, each of which is connected to a small syringe attached to either arm of the spectacles.

The wearer adjusts a dial on the syringe to add or reduce amount of fluid in the membrane, thus changing the power of the lens. When the wearer is happy with the strength of each lens the membrane is sealed by twisting a small screw, and the syringes removed. The principle is so simple, the team has discovered, that with very little guidance people are perfectly capable of creating glasses to their own prescription.

Some 30,000 pairs of his glasses have already been distributed in 15 countries, but to Silver that is not near enough. Within the next year the now-retired professor and his team plan to launch a trial in India which will, they hope, distribute 1 million pairs of glasses.

The target, within a few years, is 100 million pairs annually.

Another WTF?!? Moment… The Man Has Eaten BOTH Of His Eyeballs!

But…

The Judge Ruled Him Competent When He Ate The First Eyeball!!

A Texas death row inmate with a history of mental problems pulled out his only good eye and told authorities he ate it. Andre Thomas, 25, was arrested for the fatal stabbings of his estranged wife, their young son and her 13-month-old daughter in March 2004. Their hearts also had been ripped out. He was convicted and condemned for the infant’s death.

While in the Grayson County Jail in Sherman, Thomas plucked out his right eye before his trial later in 2004. A judge subsequently ruled he was competent to stand trial.
