(PhysOrg.com) -- `Most current hard x-ray interferometers are based on crystals, which require their high quality and high mechanical stability,` Anatoly Snigirev tells PhysOrg.com. `This can make x-ray interferometry quite limited. What we have done is develop a different set up that is simpler.` Snigirev is a scientist at ESRF in Grenoble France. Along with scientists at the Russian Kurchatov Research Center in Moscow, and at IMT RAS in Chernogolovka, Russia, Snigirev proposes that refractive bilenses made from silicon can be used in place of crystals. http://www.physorg.com/news169383826.html Physics Thu, 13 Aug 2009 12:06:21 EST news169383826 Lions, giraffes, tigers, rabbits, bears, rhinos and even owls can go blind from cataracts, but an east German firm has an answer: custom-made "contact lenses". http://www.physorg.com/news166941175.html Biology Thu, 16 Jul 2009 06:20:03 EST news166941175 While the majority of patients with common vision problems can find glasses or contact lenses fairly easily, others who suffer from diseases of the eye that affect the focus of light have more limited options and may simply have to learn to live with poor vision. http://www.physorg.com/news161441645.html Medicine & Health Wed, 13 May 2009 13:54:31 EST news161441645 (PhysOrg.com) -- 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. http://www.physorg.com/news161277474.html Physics Mon, 11 May 2009 16:18:36 EST news161277474 Nocturnal geckos are among the very few living creatures able to see colors at night, and scientists' discovery of series of distinct concentric zones may lead to insight into better cameras and contact lenses. http://www.physorg.com/news160941503.html Biology Thu, 07 May 2009 18:59:15 EST news160941503 Contact lenses are great for sight, but do they have an impact on general eye health? Researchers at the University of Alabama at Birmingham (UAB) School of Optometry are working to answer that question by analyzing tears. http://www.physorg.com/news160848590.html Medicine & Health Wed, 06 May 2009 17:10:39 EST news160848590 You've probably been there. In a doctor's office, being advised to do what you dread - exercise. You get that feeling in your gut, acknowledging that, indeed, you should exercise but probably won't. Now imagine that the doctor is your optometrist. http://www.physorg.com/news157727040.html Medicine & Health Tue, 31 Mar 2009 14:10:21 EST news157727040 (PhysOrg.com) -- Biofilms are everywhere - in dental plaque and ear canals, on contact lenses and in water pipelines - and the bacteria that make them get more resilient with age, finds a new study in FEMS Microbiology Letters. http://www.physorg.com/news156088573.html Biology Thu, 12 Mar 2009 14:56:40 EST news156088573 Children wearing contact lenses felt better about how they look, their athletic abilities and acceptance by their friends than did children wearing eyeglasses in a recent study. http://www.physorg.com/news155188309.html Medicine & Health Mon, 02 Mar 2009 03:52:24 EST news155188309 (PhysOrg.com) -- Researchers from the University of Arizona have created a fluid-based opthalmic lens in which the amount of fluid can be constantly adjusted to provide customized eye correction. The lens may one day be incorporated into the tools that eye doctors use to determine prescription strength. http://www.physorg.com/news154705159.html Physics Tue, 24 Feb 2009 13:40:08 EST news154705159 Contact lenses increase the risk of infection with pathogenic protozoa that can cause blindness. New research, published in the November issue of the Journal of Medical Microbiology, shows that a high percentage of contact lens cases in Tenerife are contaminated with Acanthamoeba that cannot be killed by normal contact lens solution. http://www.physorg.com/news143712703.html Biology Mon, 20 Oct 2008 09:11:43 EST news143712703 (PhysOrg.com) -- University of Wisconsin-Madison engineers have developed tunable liquid microlenses that can quickly scan images and record video. Integrated onto fiber-optic probes, the lenses further could reduce the invasiveness of such minimally invasive diagnostic medical procedures as endoscopies. http://www.physorg.com/news143126178.html Physics Mon, 13 Oct 2008 14:16:18 EST news143126178 "Smart" contact lenses that measure pressure within the eye and dispense medication accordingly could be made possible using a new material developed by biomedical engineers at UC Davis. http://www.physorg.com/news136655207.html Biology Wed, 30 Jul 2008 16:46:47 EST news136655207 Even contact lenses are joining the trend to go green. Chemical engineering researchers at McMaster University have shown that a common fluid found in our bodies can be used as a natural moisturizing agent in contact lenses. http://www.physorg.com/news134743060.html Chemistry Tue, 08 Jul 2008 13:37:40 EST news134743060
