New evidence that popular dietary supplement may help prevent, treat cataracts
Researchers are reporting evidence from tissue culture experiments that the popular dietary supplement carnosine may help to prevent and treat cataracts, a clouding of the lens of the eye that is a leading cause of vision loss worldwide. view more (2009-07-16)
Contact lenses with circuits, lights a possible platform for superhuman vision
Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes -- visual aids to help vision-impaired people, holographic driving control panels and... view more... (2008-01-18)
Report issued on outbreak of serious eye infection linked with use of certain contact lens solution
Researchers have additional information concerning the recent outbreak of the corneal infection Fusarium keratitis, which was associated with use of a specific contact lens solution. view more (2006-08-23)
Contact lens wearers at risk from blinding infection
Some 2.2 million people wear contact lenses in England, with 900,000 alone in the southeast. Given the growing popularity in fashion contact lenses for night-clubbers, and for people who want a temporary change of eye colour, there needs to be greater awareness about the risks involved when people fail to clean their lenses properly. Dr Naveed... view more... (2003-11-03)
Study suggests simple way to make near-perfect lenses
A new study from the University of Edinburgh and Pennsylvania State University suggests a smart solution to one of the biggest challenges facing the optics and electromagnetics sector - how to produce near-perfect lenses cheaply. view more (2005-09-08)
Reports characterize fungal eye infections among soft contact lens wearers
Fusarium, the fungus implicated in recent eye infections among soft contact lens wearers, is associated with an increasing number of cases of keratitis (corneal swelling and inflammation). view more (2006-06-13)
Contact lens solutions may not kill off harmful eye bugs
Contact lens solutions may not kill off harmful eye bugs, reports a study in the British Journal of Ophthalmology. view more (2002-01-25)
Impaired vision common in US
A new report estimates that approximately 14 million people aged 12 years and older in the U.S. have vision impairment, of which more than 80 percent could be improved with the use of corrective lenses. view more (2006-05-10)
Custom-sized microlenses
Optical components have joined the trend towards miniaturization. There have, however, been no methods available thus far to produce custom-sized glass lenses. A new process now enables the low-cost, high-volume manufacture of microlenses with extreme dimensions. view more (2004-08-27)
Precision optics hot off the press
Optical lenses have already become a mass product. They focus the bar code laser at the supermarket checkout, record pictures in cameras and mobile phones and control the transmission of data along fiber optic telecommunications cables. Automated production processes help to meet this ever-increasing demand for lenses. While simple plastic lenses... view more... (2003-04-24)
Reversible Microlenses to Speed Chemical Detection
The microlenses make use of the antibody-antigen binding, the same process used by the human immune system, to detect biological or chemical agents. view more (2006-02-14)
UCF, Holochip Corp. announce global licensing agreement for zoom lens patents
The University of Central Florida has signed a licensing agreement with Holochip Corp. for a portfolio of technologies that will allow zoom lenses, such as those used in digital cameras and camera phones, to be manufactured at a dramatically smaller size without compromising clarity. view more (2007-07-23)
'Smart' sunglasses and goggles let users adjust shade and color
Imagine a single pair of glasses with lenses that can be transparent or dark, and in shades of yellow, green or purple, all on command. A new lens with chameleon powers promises to dramatically improve sunglasses' function. view more (2007-03-28)
Mini-beamer in a cell phone or PDA
A summer barbecue by the lake - as the sausages sizzle on the grill some of the party would like to watch the soccer on TV. Today, a choice has to be made whether to stay by the lake or watch the match on a big public screen or the TV set at home. view more (2009-06-25)
UIC investigates eye infections tied to contact lens use
The use of a particular contact lens solution has a strong association with Acanthamoeba keratitis, a rare severe eye infection. view more (2007-06-14)
Perfect image without metamaterials ... and a reprieve for silicon chips
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. view more (2009-09-29)
Nanocoating could eliminate foggy windows and lenses
Foggy windows and lenses are a nuisance, and in the case of automobile windows, can pose a driving hazard. view more (2005-08-29)
Kids think eyeglasses make other kids look smart
Young children tend to think that other kids with glasses look smarter than kids who don't wear glasses, according to a new study. Children between the ages of 6 and 10 who were surveyed for the study also thought that kids wearing glasses looked more honest than children who don't wear glasses. view more (2008-05-13)
Can you see me now? Flexible photodetectors could help sharpen photos
Distorted cell-phone photos and big, clunky telephoto lenses could be things of the past. University of Wisconsin-Madison Electrical and Computer Engineering Associate Professor Zhenqiang (Jack) Ma and colleagues have developed a flexible light-sensitive material that could revolutionize photography and other imaging technologies. view more (2009-01-14)
Engineers demonstrate a new type of optical tweezer
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) demonstrated a new type of optical tweezer with the potential to make biological and microfluidic force measurements in integrated systems such as microfluidic chips. view more (2008-02-26)
