The app is a game meant to strengthen your visual reaction time, and consequently make you a better point guard, baseball hitter, and so on. It’s not a new idea, especially in baseball, where vision science has made its way into MLB clubhouses, and vision training apps have sprung up.

But Game Vision is trying to appeal to a younger crowd, with a kid-focused design and the Chris Paul endorsement.

This aspect was actually a big thing that drew Paul to the app, as a father who admits his own cell phone is populated with tons of kids games.

“I was able to give [the app developers] feedback both as a professional athlete and as a father,” he tells Business Insider.

Paul has done a bit of computer coding himself, and his brother actually majored in computer science, but he didn’t have any technical role in the app development. That doesn’t mean he just put his name on it though. Paul and his son tested the app together and worked with the team to make changes, he says.

So did the app improve his son’s reactions?

“Well, he is six,” he laughs. But proud papa Paul did note that his son got on base three times in his latest baseball game.

Game Vision works by having you tap targets as they appear in circles, which in turn destroy brick formations.

Here’s what Game Vision is like to play:

Ocumetics Bionic Lens

Ocumetics’ Bionic Lenses offer relief from cataracts and a new generation of wearable camera optics

Originally posted by the  vancouversun.com / rshore@vancouversun.com @theGreenManblog

Can the Ocumetics 8 Minute Surgery Give You Superhuman Vision For Life

Ocumetics Visual scientist Garth Webb is harnessing cutting-edge technology to improve one of nature’s most dazzling devices: the human eye.

Webb’s trademarked Bionic Lens is about to begin animal and human trials, in which a highly responsive manufactured lenses is surgically implanted into the eye.

The Ocumetics lens is being developed initially as a replacement for lenses damaged by cataracts, which cause the eye’s natural lens to cloud and even release toxins that can damage the cornea, retina and other structures of the eye.

But the implants — which replace the natural lenses inside the eye — don’t just restore 20/20 vision, they allow the patient to see three times better than normal without ever needing glasses.

In fact, Webb foresees a future in which no one needs glasses and any person whose faulty natural lenses are replaced with Bionic Lenses would never develop cataracts.

The Bionic Lens is uniquely responsive to the muscles that control the shape and thickness of the eye’s natural lenses, which allow us to focus on far away landscapes and closely held fine print, but requires only 1/100th of the energy used to control a natural lens. Natural lenses tend to stiffen with age, while the muscles of the eyes weaken.

With Ocumetics implants, no matter how old you and your eyes get, the muscles will never strain to control and focus the implants, Webb explained.

Ocumetics is also using its lens technology to develop revolutionary 3-D camera optics that — unlike traditional glass lenses — mimic the function of human eyes, from changing the focus of the lens from infinity to just a few centimetres in a fraction of second and making imperceptibly quick adjustments to the lateral convergence of the lenses that enable humans to see in stereo, with three-dimensional depth.

The images captured — whether in the Amazon jungles or the surface of Mars — are naturally formatted for the human visual system and perceived by the brain as though you are walking through a “hyper-real” landscape.

That immersive Human Visual Experience (also trademarked) in a wearable technology not unlike Google Glass is something today’s gamers can only dream about, and one that can be recorded and shared with other people anywhere in the world.

“You can essentially live the entire visual experience of another person,” Webb explained. “Or, rather than having a computer screen on my desk, I could just command a virtual screen and control it with visual commands,” said Webb.

Webb envisions such wearable tech replacing computer screens and televisions.

Wearable stereoscopic cameras resembling ordinary sunglasses fitted with Ocumetics Camera Optics (TM) could enable us to see infrared and ultraviolet light, slip into the visual experience of a bomb-defusing robot, call up illuminated night vision and even view the workings of the human body just beneath the skin, all of this projected onto the brain’s own movie screen, said Webb.

“I’ve been quite fortunate to develop these mechanical concepts in an age in which we have the materials to make these things and the lasers to micromachine them to have the properties that we need,” he said. “The technology for many of these applications has already arrived. It’s a special moment.”

The horrible past

As we humans live longer and longer, we tend to outlive some of our less durable parts, the lenses of the eye among them, said Webb. As a result, cataracts have become the world’s leading cause of blindness in people over 40.

Until just a few decades ago the surgery to remove cloudy lenses was nothing short of horrible, requiring an ugly scalpel incision and large stitches.

“They would use a cryoprobe to attach to the lens and literally yank it and all the connective structures out,” said Webb. The trauma to the eye was so extreme that to avoid retinal detachment, the person would have to lie and look straight up at the ceiling for two weeks.”

The patient would then be fitted with glasses sporting “big, thick, humongous lenses.”

Webb graduated from the University of Waterloo’s School of Optometry, after gaining early admission based on superior performance in his first year of general science.

“I left university with the notion that I wasn’t just being trained as an optometrist, but that I was being trained as a visual scientist,” he said.

The young Dr. Webb quickly learned that the existing technology was not meeting the needs of patients.

He recalled early in his career explaining the procedure to a patient who could neither read nor drive.

“He said to me, ‘You know, I think I’d rather just die,’” he said. “And that’s what he did. He didn’t go for the surgery and he didn’t last another year.”

Profound vision loss is known to shorten lives, an effect that is more than reversed by modern cataract surgery. People who recover their vision through surgery live significantly longer, studies show.

“Cataract surgery has evolved dramatically in the last 35 years; lens removal is laser assisted and requires an incision of only 2.7 millimetres,” he said. “It’s extremely low-risk.”

But today’s lens replacements remain deeply flawed. The inert lenses widely used to replace the eye’s natural lens only restore long-distance vision, requiring patients to wear powerful glasses in order to look at a computer or read a book. And because replacement lenses don’t occupy the entire space left by natural lenses, they vibrate when the eye moves, sending damaging reverberations through the delicate structures of the eye.

A sharper future

Bionic Lenses fold up to fit through a tiny incision and then unfurl inside the space left by the natural lens, like erecting the masts of a ship inside a bottle. A “memory foam” ring bonds with the tiny muscles that operate the lens, allowing the eye’s natural structures to control the thickness and curvature of the lens while focusing, even as it minimizes the damaging vibrations caused by old-style inert lenses.

“In effect, it customizes itself to the shape of the space and the muscles in the eye,” said Webb.

Before implantation, the recipient’s eye is laser mapped to create three-dimensional model, which serves as a template for customization of the lens and its supporting structures.

“The design lends itself to mass production because there are so many similarities from eye to eye,” he said. “But in the end, each lens is made specific to each eye.”

Laser shaping of the supporting material ensures the lens will install precisely in the optical centre of the eye. The surface of the lens is sculpted to eliminate image distortion that is typical near the edge of a manufactured lens and to project the sharpest possible image onto the retina.

“We are accurate to one micron, which is one-thousandth of a millimetre,” he said. “That’s about the size of one wavelength of light.”

Ocumetics’ manufacturer is already fabricating the lenses in their final for use in clinical trials to begin this year in Canada, the United States and Australia, among other more exotic locales. Ocumetics has private and university partners committed to the process.

Webb is reticent to give more detail, because the trials’ integrity depends on patient selection independent of his firm’s influence, and, because Ocumetics is bombarded by thousands of calls from people desperate to join the trials, requests they are unable to fulfil.

Clinical trials on animals will last several months, followed immediately by human trials, the results of which will be considered by Health Canada, the U.S. Food and Drug Administration and their counterparts abroad. The first human trial participants will be blind, so no one’s vision is at risk while the tech is proven. Depending on the country, data from between 200 and 600 procedures may be required before approval for commercial sale is granted.

“In some countries we will be selling Bionic Lenses in one year,” he said. Approval in Canada may take two years and the United States slightly longer.

Gold and Lasers May Help Restore Vision to Many

Gold and Lasers May Help Restore Vision to Many
by Gene Ostrovsky on Jul 20, 2011 • 1:51 pm

At Australia’s Swinburne University of Technology research is underway to develop a method of activating optic nerves by laser stimulation.  The idea is to embed gold nanoparticles within the eye that can then be excited by lasers from within a pair of glasses.  If successful, this technology will help people suffering from eye diseases like retinitis pigmentosa and macular degeneration.

The researchers are looking for a non-contact method of stimulating nerves and are exploring the use of laser light, rather than the direct electrical stimulation techniques that have become the conventional approach.

Using a very low intensity laser source they are trying to generate the right amount of heat required to elicit a response from nerve cells without damaging them.

According to researcher PhD student Chiara Paviolo, the new concept explores the potential for light to deliver far more precise nerve cell stimulation than electrodes.

“Electrodes need an electrical current and so they consequently stimulate a group of nerves,” Paviolo said.

“Light, however, allows us to target individual nerves and this should mean more accurate communication of optical signals – an essential outcome if the information delivered to the brain via a prosthesis is to mean anything useful in terms of shapes, colours, dimensions. You don’t just want optical ‘noise’.”

The initial goal is to successfully bond the nanoparticles to the nerve and then achieve a response to light heat.

Gold nanoparticles are being used because gold is inert, biocompatible and has plasmonic or light-responsive properties. The gold nanoparticles can also be fabricated to respond to different wavelengths, making the interface controllable.

“One of the challenges is to develop nanoparticles that are thermally stable,” said Professor of Biointerface Engineering Sally McArthur . “While on one hand heat is necessary, it also has to be limited to avoid damaging cells. Laser heat has long been used in medicine to deliberately kill tissue, but in this instance the opposite result is sought.”

To measure and control the heat, the Swinburne team is building a molecular thermal sensor to measure how much heat is produced, so they can then work out how to control it.
