VISTA, Calif., Dec. 8 /PRNewswire/ -- Ophthonix, the innovators who introduced non-surgical high definition vision technology to the market so that consumers have crisper, clearer and more vivid vision than ever before, today announced the launch of customized iZon® SL(TM) Polarized Lenses. The new iZon SL Polarized Lenses provide wearers with high definition vision, or WOW vision, in sunlight glare, even when reflected off water, land, ice and snow. The iZon SL Polarized Lens is...

Data presented at American Academy of Optometry meetingBausch & Lomb today announced that the company's Lo-Torque® lens design demonstrates significantly better rotational recovery, which can lead to more consistent vision, compared with Acuvue's accelerated stabilization design. These findings from two clinical studies were presented at Academy 2009, the American Academy of Optometry annual meeting in Orlando, Fla.Rotational recovery is defined by how quickly a contact lens returns to...

Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image "“ images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility.One exciting development was Pendry's theoretically perfect work on negative refraction, which offered the possibility of lenses that could create images with resolution not possible with conventional lenses. But this...

NEW ORLEANS, Aug. 3 /PRNewswire/ -- SIGGRAPH 2009 -- Caustic Graphics(R) today announced that Lightwork Design, Robert McNeel & Associates, Realtime Technology AG (RTT AG), Right Hemisphere and SplutterFish have all agreed to port their interactive raytracing applications to the CausticRT(TM) platform, showing strong momentum early on behind the world's only massively accelerated raytracing system for achieving breakthrough levels of quality in interactive, cinema-quality 3D computer...

Researchers at the University of Houston's College of Optometry say they have created custom-made contact lenses for people with highly aberrated vision. While the majority of patients with common vision problems can find glasses or contact lenses fairly easily, the researchers said others who suffer from eye diseases that affect the focus of light have more limited options and might have to learn to live with poor vision. The lenses we make are made for (the specific patient), Assistant...

Like tiny Jedi knights, tunable fluidic micro lenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to a team of Penn State engineers. They may also provide imaging in medical devices, eliminating the necessity and discomfort of moving the tip of a probe.Conventional, fixed focal length lenses can focus light at only one distance. The entire lens must move to focus on an object or to change the direction of the light....

U.S. scientists say they've developed a light imaging technology that could lead to creation of more powerful microscopes and other optical devices. Princeton University researchers said when photographers zoom in on an object to see it better, they lose the wide-angle perspective -- they are forced to trade off big picture context for detail. The scientists say their new imaging method might also lead to lenses that show all parts of a scene at once in the same high detail. It allows you to...

Company Releases Caustic RT - Flexible Development Platform for No-Compromise Raytracing SAN FRANCISCO, April 20 /PRNewswire/ -- Today Caustic Graphics released CausticRT(TM), the worlds only massively accelerated raytracing system for achieving breakthrough levels of quality in interactive, cinema-quality 3D computer graphics. The Caustic development platform, which includes a raytracing accelerator card and SDK, are now available to qualified developers so they can create new or port...

Company Set to Launch the World's First Massively Accelerated Raytracing Solution SAN FRANCISCO, March 10 /PRNewswire/ -- Caustic Graphics(R), a new 3D computer graphics company, launches today with a fundamental breakthrough in raytracing acceleration that is set to define a new era in professional 3D production and interactive consumer graphics. Raytracing, the gold-standard for creating 3D imagery, duplicates the natural physics of light, creating stunning images by meticulously tracing...

Lensbaby, LLC (formerly known as Lensbabies, LLC) is launching today an entire new system of selective focus lenses at the Photokina tradeshow in Cologne, Germany. Three new Lensbaby lenses - The Composer(TM), The Muse(TM) and The Control Freak(TM), - make up the new line of products. Each features the Lensbaby Optic Swap system. The new Muse and the new Control Freak replace the current Original, Lensbaby 2.0, and Lensbaby 3G lenses, which are being phased out. With the Composer,...
