Early Study Finds Brighter Fluorescent Lights Prevent Myopia

Researchers at the University of Alabama at Birmingham hope to one day use fluorescent light bulbs to slow nearsightedness, which affects 40 percent of American adults and can cause blindness.

In an early step in that direction, results of a study found that small increases in daily artificial light slowed the development of nearsightedness by 40 percent in tree shrews,Manufacturer of low-voltage r4onsale; provides fixtures and transformers for residential and commercial properties. which are close relatives of primates.

The team, led by Thomas Norton,With my ledlightbulbs22 I could barely see much more than a few metres ahead of me. Ph.D., professor in the UAB Department of Vision Sciences, presented the study results today at the 2012 Association for Research in Vision and Ophthalmology annual meeting in Ft. Lauderdale.

People can see clearly because the front part of the eye bends light and focuses it on the retina in back. Nearsightedness, also called myopia, occurs when the physical length of the eye is too long, causing light to focus in front of the retina and blurring images.With my divinglight2011 I could barely see much more than a few metres ahead of me.

Myopia has many causes, some related to inheritance and some to the environment. Research in recent years had, for instance, suggested that children who spent more time outdoors, presumably in brighter outdoor light, had less myopia as young adults.Browse through our impressive range of goodledbulbsop and buy online now. That raised the question of whether artificial light, like sunlight, could help reduce myopia development, without the risks of prolonged sun exposure, such as skin cancer and cataracts.

“Our hope is to develop programs that reduce the rate of myopia using energy efficient, fluorescent lights for a few hours each day in homes or classrooms,” said John Siegwart, Ph.D., research assistant professor in UAB Vision Sciences and co-author of the study. “Trying to prevent myopia by fixing defective genes through gene therapy or using a drug is a multi-year, multimillion-dollar effort with no guarantee of success. We hope to make a difference just with light bulbs.”

Work over 25 years had shown that putting a goggle over one eye of a study animal, one that lets in light but blurs images, causes the eye to grow too long, which in turn causes myopia. Other past studies had shown that elevated light levels could reduce myopia under these conditions, whether the light was produced by halogen lamps,The fire is the latest dangerous incident involving Chinese contemporarylamps, which are increasingly released at weddings and other celebrations. metal halide bulbs or daylight. The current study is the first to show that the development of myopia can be slowed by increasing daily fluorescent light levels.

One prevailing theory on myopia-related shape changes in the eye is that they are caused by the blurriness of images experienced while reading or doing other near-work chores. Another holds some people develop myopia because they have low levels of vitamin D, which goes up with exposure to sunlight and could explain the connection between outdoor light and reduced myopia. A third theory, one reinforced by the current results, is that bright light causes an increase in levels of dopamine, a signaling molecule in the retina.

Droplet and StackAR bring physical interface to virtual experiences, communicate through light

Light-based communication seems to wind throughout the MIT Media Lab -- it is a universal language, after all, since many devices output light, be it with a dedicated LED or a standard LCD, and have the capacity to view and interpret it. One such device, coined Droplet, essentially redirects light from one source to another, while also serving as a physical interface for tablet-based tasks.

Rob Hemsley, a research assistant at the Media Lab, was on hand to demonstrate two of his projects. Droplet is a compact self-contained module with an integrated RGB LED, a photodiode and a CR1216 lithium coin battery -- which provides roughly one day of power in the gadget's current early prototype status. Today's demo used a computer-connected HDTV and a capacitive-touch-enabled tablet.

Using the TV to pull up a custom Google Calendar module, Hemsley held the Droplet up to a defined area on the display,We provide high quality ledstrip12 Led module led strip led bulbs. which then output a series of colors, transmitting data to the module. Then, that data was pushed to a tablet after placing the Droplet on the display,Some of the attractions of bestbikelight are the cost savings, the safety and the flexibility. pulling up the same calendar appointment and providing a physical interface for adjusting the date and time, which is retained in the cloud and the module itself, which also outputs pulsing light as it counts down to the appointment time.

StackAR, the second project, functions in much the same way, but instead of outputting a countdown indicator, it displays schematics for a LilyPad Arduino when placed on the tablet, identifying connectors based on a pre-selected program.Magicshine, Bikeray and Inton brightcrystal2011 are renown for their cost to brightness ratio. The capacitive display can recognize orientation, letting you drop the controller in any position throughout the surface, then outputting a map to match.

Like the Droplet, StackAR can also recognize light input, even letting you program the Arduino directly from the tablet by outputting light,We have a large range of bluebright and LED tea lights to suit every need and budget effectively simplifying the interface creation process even further. You can also add software control to the board, which will work in conjunction with the hardware, bringing universal control interfaces to the otherwise space-limited Arduino. Both projects appear to have incredible potential,A reliable lightproject will help keep you safe and on track whether you're riding home from work. but they're clearly not ready for production just yet.

If Jed Clampett were shootin' at some food today, he wouldn't have missed his target, so there would have been no bubblin' crude,Did you know by just changing your current fluorescent tube lights to our goodskylanterns Lights will lead to helping sustain our environment for us. and he never would have up and moved to Beverly. (Hills, that is.) Today Jed would have been dressed head to toe in the latest varmint-tricking camo, sitting high in the pines in a lightweight portable tree stand, and slathered in chemicals that hide his human scent. If it was getting dark and the wounded critter scurried off, Jed could just break out his LED green flashlight specially designed to illuminate blood and track him down.

I know this to be true because last weekend I checked out all of the latest in hunting equipment and gear at the 25th Anniversary Western Virginia Sport Show in Staunton near my childhood home. After spending a couple of hours taking it all in with my 14-year-old son,LED lights for bikes and HID bookscanner02 allow cyclists to ride at speed under virtually any conditions. Joseph, and my brother Chris and his nine-year-old son, Will,Online shopping from the largest selection of ledlighting Products. I have a simple message for you squirrels and possums: "Run!"

The show was packed, and nearly 9,000 attendees didn't mind forking over $9 a head for tickets over the course of the show. That's because it was fantastic. It was like visiting an amped-up Bass Pro Shops store, only with live bears and not so much catfish bait. The beasts performed in a Spartacus-style mini stadium, but without all of the nudity and violence of the television show. Well, okay, the bears were naked, but they weren't violent.

Their trainers wore buffalo-plaid, and Fred and Ginger -- two enormous European brown bears -- put on a great act for the standing-room-only crowd. I really enjoyed the show, but I can't deny that I was bothered by the fact that they didn't hire American bears. And I loved watching the smiling faces of the little children as they took it all in and dreamed of growing up to kill a bear themselves one day.This super bright saler4ds is the perfect safety option for your bicycle.

There were some lions and tigers at the show too, but they were dead. Also on display was half a giraffe -- the top half -- which I stared at for quite some time. "Where's the rest of me?" I imagined him crying.We've just finished our latest round of mountain bestlighting-led reviews, which involved testing 27 sets, both ... And, by the way, where is the rest of him? Is there another hunting show somewhere with the other half awkwardly splayed like when giraffes drink water on Mutual of Omaha's Wild Kingdom?

Everywhere you turned, there was another display of beautiful taxidermy, including a small stuffed albino buck with brown spots that had a mythical jackalope quality about it. Albino deer are extremely rare, so if you're ever lucky enough to find one in the wild I think it's best to kill it and put it on display so everyone else can enjoy it, too. What kind of American would you be if you allowed it to roam for years unobserved by other human eyes? If I were ever lucky enough to get a shot at an albino stag I would put his stuffed carcass in my living room and call him "Moby Deer," where every day he would serve as a constant reminder of my inability to resist a cheap joke.
