Rise in Myopia Means a Boon for Eyewear Industry

"According to mounting research, myopia (nearsightedness) among the young has become a global epidemic. In the United States, myopia rates have roughly doubled over the last generation. A recent study published in JAMA reports that in China (where rates of myopia have skyrocketed to roughly 90% among urban youth), the major cause could be a lack of sun exposure. But young adults aren’t the only ones struggling to see clearly. Older adults are also looking for treatments that address their age-related vision problems. Amid rising demand, the eye care industry is poised to accelerate. It’s already developing new technologies that not only treat, but also prevent (and in some cases eliminate) vision problems," goes the post on Forbes. "With increasing demand from every age group, the $36 billion eye care industry has a bright future. The industry, which includes eye care professionals (opticians, optometrists, and ophthalmologists) and products (eye glasses, contact lenses, and corrective surgeries,) posted a steady combined annual growth rate of 3.4% from 2006 to 2012, outpacing the average growth of the economy at large (2.9%) over those years. Forecasters expect this rate to increase to 5.0% from 2014 to 2019." Read more, especially about the growth of myopia.

Researchers Turn Stem Cells into Retinal Ganglion Cells

"Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. Death and dysfunction of these cells cause vision loss in conditions like glaucoma and multiple sclerosis," according to Science Digest. "The laboratory process, described in the journal Scientific Reports, entails genetically modifying a line of human embryonic stem cells to become fluorescent upon their differentiation to retinal ganglion cells, and then using that cell line for development of new differentiation methods and characterization of the resulting cells."

Bracelete Helps Sight-Challenged Navigate

"Based on the resonance location system (echo) used by bats and dolphins to navigate, Marco Antonio Trujillo Tejeda and Cuauhtli Padilla Arias, mechatronic engineers from the Tec de Monterrey in Mexico, devised a bracelet that makes mobility simpler and safer for the blind," reports Science Digest. "Sunu band bracelet emits high-frequency sound waves (30 pulses per second) that bounce after hitting an object and are recorded by a proximity sensor that calculates the distance, which translates into vibrations directly into the wearer's wrist; as the person get closer to the objects, the pulses will be more frequent."

Amblyopia Causes Slow Reading in Children

"Children with amblyopia, commonly known as 'lazy eye,' may have impaired ocular motor function," reports Medical News Today. "This can result in difficulties in activities for which sequential eye movements are important, such as reading. A new study conducted at the Retina Foundation of the Southwest determined that children with amblyopia read more slowly than children with normal vision or with strabismus alone. Their findings are published in the Journal of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS)." Read more.

Cataract Surgery Can Reduce Dizziness

Help Parents Prevent Injuries This Holiday Season

In 2013, the U.S. Consumer Product Safety Commission (CPSC) estimated that hospital emergency rooms across the country treated 265,700 toy-related injuries, compared to 265,000 the year before. And, 73 percent of those injuries were to children under the age of 15. In fact, approximately 83,700 were to those under 5 years of age. Commonly injured body areas included lacerations, contusions, or abrasions near the head and face. Usually the injuries were caused by non-motorized scooters, toy balls, and toy vehicles.

How We See Motion and Still Objects

"A Dartmouth study reveals how the brain understands motion and still objects to help us navigate our complex visual world," notes Medical News Today. "The findings have a number of potential practical applications, ranging from treatment for motion blindness to improved motion recognition algorithms used in airport and other public security systems. The study appears in the journal Neuroimage. ...Our brain's visual system consists of a 'where' (dorsal) pathway and a 'what' (ventral) pathway. A normally function brain can imply motion from still pictures, such as the speed line in cartoons being interpreted as motion streaks of a still object. However, patients with lesions to the dorsal pathway know where objects are but have difficulty recognizing them, while patients with lesions to the ventral pathway have trouble recognizing objects but no problem locating them."

Seeing Is Not as Simple as Black and White, Says Scientists

"While some things may be 'as simple as black and white,' this has not been the case for the circuits in the brain that make it possible for you to distinguish black from white," reports Medical News Today. "The patterns of light and dark that fall on the retina provide a wealth of information about the world around us, yet scientists still don't understand how this information is encoded by neural circuits in the visual cortex--a part of the brain that plays a critical role in building the neural representations that are responsible for sight. But things just got a lot clearer with the discovery that the majority of neurons in visual cortex respond selectivity to light vs dark, and they combine this information with selectivity for other stimulus features to achieve a detailed representation of the visual scene."

Vision Test Used to Determine Cognitive Ability

Science Digest reports, "A simple technique to measure an individual's visual processing speed -- the speed at which an individual can comprehend visual information -- has been developed in order to identify whether or not they may have cognitive issues. The recent study focuses on using a simple test of visual flicker to evaluate an individual's level of executive cognitive abilities." Read more.

Humans Have the Best of Al Visual Worlds, Prove Scientists

"Humans have the best of all possible visual worlds because our full stereo vision combines with primitive visual pathways to quickly spot danger, a study led by the University of Sydney has discovered," notes Science Digest. "The surprising finding published today in Current Biology shows that in humans and other primates, information from the eyes is not only sent to the visual cortex for the complex processing that allows stereoscopic vision, but also could feed directly into deep brain circuits for attention and emotion. 'The brain cells that we identified suggest that human and other primates retain a visual pathway that traces back to the primitive systems of vertebrates like fish and frogs,' said University of Sydney's Professor Paul Martin from the Sydney Medical School, who led the team that made the discovery."

EU Court Rules Cosmestic Contact Lenses Not Cosmetic

"On 3 September 2015, the Court of Justice of the European Union (CJEU) delivered its ruling in case C-321/14 Colena AG v Karnevalservice Bastian GmbH following a reference from the Landgericht Krefeld (Regional Court Krefeld, Germany) as whether non-corrective colour contact lenses fell within the scope of Regulation (EC) No 1223/2009 (the "Cosmetic Regulation")," reports Lexology. "The effect of the ruling is that the Cosmetic Regulation must be interpreted such that contact lenses marketed purely to alter the user's appearance (rather than to correct vision) will not be within its scope even if the outer packaging declares that the product is a cosmetic, subject to the EU Cosmetics Directive."

A Talk with Architect/Eyewear Designer Philippe Starck

"Philippe Starck is telling me about how he doesn’t like nightclubs. That’s right. The acclaimed French designer who outfitted the famous Parisian clubs La Main Bleue and Les Bains Douches—essentially the Studio 54 of Paris—doesn’t like going out." That's the start of a Bloomberg post about architect/eyewear designer Starck. "We’ve met to discuss his eyewear line, which—unbeknownst to many—has been around for nearly 20 years. His newest collection, Resort 2016, will mark a new direction for the designer and the Starck Eyes brand, which aims to target the more evolved, fashion-conscious male consumer interested in the intersection of technology and style. The frames, generally slim, are now available in the thinnest acetate frames ever, as well as in larger, youthful styles. Masculine square shapes, with a retro bent, put the frames in a luxury design category populated by such eyewear brands as Tom Ford and Persol." Read more.
