Hair-sized lens helps look in blood vessels
A tiny measurement system that incorporates a lens as thick as two human hairs has been developed by researchers to investigate the force exerted on the wall of an artery as blood whooshes past. In a research paper published today in the Institute of Physics publication Journal of Micromechanics and Microengineering, Dr Rob Keynton and colleagues... view more... (2002-03-20)
Telescope embedded in glasses lens promises to make driving easier for visually impaired
Glasses embedded with a telescope promise to make it easier for people with impaired vision to drive and do other activities requiring sharper distance vision. view more (2008-07-25)
Seeing Through the Skin
Feeling blue? According to Prof. Leonid Yaroslavsky from Tel Aviv University, the saying may be more than just a metaphor. view more (2008-09-12)
An artificial cornea is in sight, thanks to biomimetic hydrogels
If eyes are "the windows of the soul," corneas are the panes in those windows. They shield the eye from dust and germs. They also act as the eye's outermost lens, contributing up to 75 percent of the eye's focusing power. view more (2006-09-12)
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)
Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. view more (2007-10-15)
Scientists demonstrate laser with controlled polarization
Applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, lasers in which the direction of oscillation of the emitted radiation, known as polarization, can be designed and controlled at will. view more (2009-04-13)
Coating copies microscopic biological surfaces
Someday, your car might have the metallic finish of some insects or the deep black of a butterfly's wing, and the reflectors might be patterned on the nanostructure of a fly's eyes. view more (2008-09-18)
Freshwater supplies threatened in central Pacific
An international team from The Australian National University, Ecowise Environmental, the Government of the Republic of Kiribati, the French agency CIRAD and the Pacific Islands Applied Geoscience Commission has been studying the impacts of natural and human-induced changes on groundwater in the central Pacific nation of Kiribati since 1996. view more (2007-08-15)
Caltech bioengineers develop 'microscope on a chip'
Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip. view more (2008-07-29)
University of Warwick Designer Polymer Company Wins Business Equivalent of Pop Idol Competition
A University of Warwick spin-out company specialising in designer polymers has won the prestigious Enterprise Launch Pad award at this year's Cambridge Enterprise Conference. The company, Warwick Effect Polymers, wins £5,000 but also importantly it gives them entrance to a "deal day" where a select group of companies get the... view more... (2002-09-19)
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)
Nanofabrication method paves way for new optical devices
An innovative and inexpensive way of making nanomaterials on a large scale has resulted in novel forms of advanced materials that pave the way for exceptional and unexpected optical properties. view more (2007-10-08)
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)
Study shows how disruption of spectrin-actin network causes lens cells in the eye to lose shape
A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al. view more (2009-09-14)
New 'implanted contacts' designed to fix nearsightedness
UT Southwestern Medical Center ophthalmologists will be the first in the area to insert a new type of implanted lens to fix nearsightedness. view more (2006-02-28)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
UCSB researchers show how to make polymeric micro- and nanoparticles
Researchers in the College of Engineering at UC Santa Barbara have discovered how to make polymeric micro- and nanoparticles in a wide variety of different shapes and sizes using commonly-available lab chemicals and equipment. view more (2007-07-10)
New hope for migraine sufferers
Nearly one in ten adults suffers from migraine UK male sufferers alone lose 4m working days with an estimated productivity loss of £750m Migraine accounts for more than half of all headaches New collaborative research by City University, the University of Essex and the Institute of Optometry, London shows that coloured filters are effective... view more...

When every photon counts
The eyes of nocturnal mammals have very large numbers of highly-sensitive rod photoreceptors (the cell type responsible for night vision). They have to perceive light which is less than a millionth of the intensity of daylight. view more (2009-04-17)
