Molecular machines drive plasmonic nanoswitches
Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch. view more (2009-02-12)
Research warns against sleeping in contact lenses
Sleeping in contact lenses can lead to an increased risk of severe eye infection, new research suggests. But new generation contact lenses, the investigation reveals, perform better in this regard than their predecessors. view more (2005-03-21)
Denser computer chips possible with plasmonic lenses that 'fly'
Engineers at the University of California, Berkeley, are reporting a new way of creating computer chips that could revitalize optical lithography, a patterning technique that dominates modern integrated circuits manufacturing. view more (2008-10-23)
Organisms found on contact lenses can provide clues to cause of corneal eye infection
Cultures of contact lenses may sometimes identify the organisms involved in cases of corneal eye infection, according to a report in the September issue of Archives of Ophthalmology. view more (2007-09-11)
Tiny holes offer surprising insights
Researchers from Berlin and Seoul store light in plasmonic crystals view more (2005-03-04)
Study suggests wearing no-line bifocals slows myopia progression in some children
Certain children who wear a special kind of no-line bifocal lenses show signs of slower progression of myopia than those who wear more conventional lenses according to a new study published in Investigative Ophthalmology & Visual Science (IOVS). view more (2007-03-15)
Dual-focus lenses cut thick metal fastest
V&S Scientific, the UK company that licenses the technology from the Force Institute in Denmark, says that demand for the dual focus lenses is beyond expectation, even though they cost much more than conventional optics for laser cutting. The company exceeded its 1999 sales projections for the lenses by the Spring, reports the July issue of Opto... view more... (1999-06-30)
Millions turn a blind eye to dangerous driving
As many as 2.5 million adults in the UK are putting themselves and others at risk by deliberately ignoring the fact that they have bad eyesight. Most do so largely because of outdated information about contact lenses and preconceived ideas about glasses, a study by Dr June McNicholas, senior research psychologist at the University of Warwick,... view more...

Contact lenses inside the eyes
INASMET Foundation, a member of the TECNALIA Corporation from the Basque Country, is currently carrying out research on intraocular lenses. In fact, INASMET presented two projects at the 17th European Congress on Biomaterials held in Barcelona. Apart from publishing the results of a comparative study on intraocular lenses, they presented a... view more... (2003-01-03)
Contact lenses are home to pathogenic amoebae
Contact lenses increase the risk of infection with pathogenic protozoa that can cause blindness. view more (2008-10-21)
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 lens wearers in southern England at nine times the risk of serious eye infection
Contact lens wearers living in southern England are at nine times the risk of developing serious eye infection, finds research in the British Journal of Ophthalmology. Hard water could be to blame, suggest the authors. The research team examined feedback from the British Ophthalmic Surveillance Unit on new cases of acanthamoeba keratitis reported... view more...

Self-moisturizing contact lenses, naturally
Even contact lenses are joining the trend to go green. view more (2008-07-09)
A drug-dispensing contact lens
Taking eye drops multiple times a day can be difficult for patients to do, and because of blinking and tearing, as little as 1 to 7 percent of the dose is actually absorbed by the eye. view more (2009-07-22)
Researchers find 400% Increase in Pulling Power if You Drop Glasses for Contact Lenses
There's more to the saying "men seldom make passes at girls who wear glasses" than meets the eye. Indeed, whether you're a man or a woman, wearing contact lenses on a night out could increase your chances of 'pulling' by as much as four times. This is one of the conclusions of a study carried out by University of Warwick psychology... view more... (2002-09-30)
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)
OHSU eye doctor says laser surgery safer than contacts
Traditional assumptions have held that contact lenses are safer than laser surgery to correct vision problems. view more (2006-10-10)
Contact lenses purchased over Internet may place individuals at risk for harmful eyecare practices
Purchasing contact lenses online may save consumers time, but the process could cause more problems in the long run, according to a new study reported in the January issue of Optometry: Journal of the American Optometric Association. view more (2008-01-07)
Hopkins study shows 30-day soft contact lenses pose very small risk of vision loss
A team of researchers led by the Johns Hopkins Wilmer Eye Institute have determined that the corneal infection rate associated with the use of 30-day -extended-wear contact lenses made from silicone hydrogel is comparable to that previously reported for older lens types worn for fewer consecutive 24-hour periods. view more (2005-12-02)
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)
