Flat lens offers a perfect image
Applied physicists at Harvard University have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. At a mere 60 nm thick, the flat lens is essen...
Robotics: Artificial insect eyes
A multi-lens artificial eye that can adapt to light mimics the eyes of arthropods such as the fruitfly.Whereas human eyes — and most cameras — use a single lens, the compound eyes of arthropods ha...
Contacts uncomfortable? Changing lens type or lens care product may help
(Wolters Kluwer Health) If your contact lenses are causing you discomfort, simply switching to a different type of contact lens or lens care product may bring improvement, reports a study, "Effect of...
An invisible knife for noninvasive surgery
A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the ne...

Improving Sleep And Promoting Recovery In Patients With Mild TBI Using Bright Light Therapy
A new study suggests that bright light therapy may improve sleep, cognition, emotion and brain function following mild traumatic brain injury (TBI). Results show that six weeks of morning bright light...
Contact lens maker Cooper Cos to sell rigid lens business in Japan
May 31 (Reuters) - Contact lens maker Cooper Cos said it would sell its rigid gas-permeable contact lens and solutions business in Japan to Nippon Contact Lens Inc for an undisclosed sum to focus on i...
Low-cost lens works well after cataract surgery
NEW YORK (Reuters Health) - After surgery for age-related cataracts, patients benefit to a similar extent from either the AcrySof SA60AT intraocular lens (IOL) from a leading manufacture (Alcon),...

Does anybody care that the crystalline lens never gets cancer?
The crystalline lens grows throughout life. New lens fibres are constantly formed as mitotic lens epithelial cells in the germinative zone undergo a process of differentiation, losing their organelles...
Tunable two-dimensional liquid gradient refractive index (L-GRIN) lens for variable light focusing.
We report a two-dimensional (2D) tunable liquid gradient refractive index (L-GRIN) lens for variable focusing of light in the out-of-plane direction. This lens focuses a light beam through a liquid me...
120 watt continuous wave solar-pumped laser with a liquid light-guide lens and an Nd:YAG rod.
We propose a simple and efficient pumping approach for a high-power solar-pumped laser by using a liquid light-guide lens (LLGL) and a hybrid pumping cavity. A 2×2 m Fresnel lens is used as a pr...
Secondary optical lens designed in the method of source-target mapping.
A secondary optical lens was designed and investigated in three-dimensional (3D) space, which was far more accurate than a two-dimensional space in far-field lighting. The shape of the lens surface wa...
Cataract surgery - essentials for the general practitioner.
Age-related cataracts are mainly caused by life-long accumulation of oxidative stress on the lens fibres. Symptoms include reduced visual acuity, requiring more light for reading, and glare. The only...
