    We've seen small scale liquid lenses progress from concepts to commerical applications, and now Joshua Silver, a retired physics professor at Oxford University, has perfected what he calls "adaptive glasses," applying similar tech in a singular and ingenious way. Aimed at helping developing nations where glasses are expensive and doctors are often in short supply, Silver's spectacles are made of tough plastic with with silicone liquid in the lenses. When purchased, each lense will have a syringe attached to it, and the wearer will be able to adjust the amount of liquid in the lenses -- which essentially changes the...

    George Washington's vision is recorded at the Library of Congress "This afternoon, as I was sitting at this table engaged in preparing a dispatch, something seemed to disturb me. Looking up, I beheld standing opposite me a singularly beautiful female. So astonished was I, for I had given strict orders not to be disturbed, that it was some moments before I found language to inquire the cause of her presence. A second, a third and even a fourth time did I repeat my question, but received no answer from my mysterious visitor except a slight raising of her eyes. "By...

    A Florida tourism group has dropped its long-standing opposition to offshore oil and gas drilling, saying that a cheap national fuel supply would trigger a boom for the Sunshine State's No. 1 industry. When gasoline prices skyrocketed to more than $4 per gallon this summer tourist spots such as Florida suffered, as would-be vacationers stayed home. So in response, the Florida Association of Convention and Visitors Bureaus (FACVB) has adopted a new policy that encourages a "comprehensive, long-term energy policy" that includes increased oil and natural gas production in the Gulf of Mexico along Florida's coast.
  • How Far Can You See at Sea?( offshore oil drilling )

    Where our line of sight hits the horizon is the distance from our boat to the horizon. A small boat first coming into view is assumed to be at that distance. In the picture above, the sailor cannot see the island's palm trees. If an object, such as a large ship or a palm tree on an island, sticks up well above the water, we can see it from a further distance. Here is how we can calculate how far we can see from a boat on the sea. First let's assume that we are sitting in the cockpit of...
  • Outdoor Activity And Nearsightedness In Children

    ScienceDaily (Aug. 5, 2008) — A growing number of the world's children are mildly to severely nearsighted (myopic), with rates especially high among urbanized East Asians. In addition to coping with poor distance vision, children with severe myopia are more prone to visual impairment and blindness later in life. Although genetic inheritance plays a role, the rapid rise of myopia suggests that environmental factors are driving the trend. Myopia usually begins and progresses during children's school years, but research on the role of intensive reading or other "near work" has determined that this is a minor factor. A new study...

    What would you do if you had the bully pulpit? What policies would you promote. What are the best ways to preserve the US and make the world a better place for our children? This is obviously a vanity, but there is a wide range of opinion represented here and clearly not enough vision is coming out of our elected government. What would you do?

    MOUNTAIN HOME, Ark. — When 9-year-old Kacie Sallee saw her father's face more clearly for the first time in her life, she had a question. "She said, 'Is that what he looks like?'" said her mother, Marinda Sallee. Kacie, who is blind, returned last week from China, where she received umbilical-cord stem cell treatment in hopes of improving her eyesight. The nearly four-week trip and medical treatment was paid through $60,000 in local donations. Kacie was born with septo-optic dysplasia, an underdevelopment of the optic nerve and pituitary gland. She could see bright colors out of her right eye but...

    May 1, 2007 — A new technique called Patterned Scanning Laser uses a computer instead of a human to apply laser pulses to burn away abnormal blood vessels. Instead of manually operating the laser, the pattern of one or two thousand laser pulses is automatically applied. Diabetes affects over 20 million Americans. It can cause many serious health problems, including blindness. Treatment for eye problems is possible, but can be extremely painful. Now, thanks to chemical physics, there is a new laser technology, called PASCAL, can treat patients in just five minutes, and virtually pain-free.

    ScienceDaily (May 19, 2008) — An improved artificial cornea, which could restore the vision of more than 10 million people worldwide who are blind due to diseased corneas, finally is moving toward reality, scientists in California conclude in a new analysis of research on the topic. Curtis Frank, Christopher Ta, David Myung, and Jennifer Cochran point out that disease or injury to the cornea -- the clear tissue covering the front of the eye -- is the second leading cause of blindness worldwide. Although treated in developed countries with transplants from donors, cornea transplants are unavailable in many parts of...

    Being able to see properly is an important part of health. Unfortunately not everyone can afford to buy themselves proper glasses. Just like used clothes or sneakers, you can donate your used glasses. LensCrafters, Pearle Vision, Sears, Target, Sunglass Hut, and BJ's Optical all donate used glasses to Give the Gift of Sight, a program that gives glasses to underprivileged people in North America and developing countries. All you have to do is drop your old glasses off at one of the locations and the program collects, cleans, repairs, and catalogs them into a computer system so they'll be properly...

    COLUMBUS, Ohio - John McCain, looking through a crystal ball to 2013 and the end of a prospective first term, sees "spasmodic" but reduced violence in Iraq and Afghanistan, Osama bin Laden dead or captured and government spending curbed by his ready veto pen. The Republican presidential contender also envisions April's annual angst replaced by a simpler flat tax, illegal immigrants living humanely under a temporary worker program, and political partisanship stemmed by weekly news conferences and British-style question periods with joint meetings of Congress. In a speech being delivered Thursday, McCain concedes he cannot make the changes alone, but...

    WASHINGTON (Reuters) - An ambitious vision to take people to the moon and Mars may fall apart before it even gets off the ground because of uncertain planning and inadequate funding, several experts said on Thursday. A congressional report said NASA's replacement for the space shuttle, the Constellation Program, is in jeopardy, and members of Congress as well as at least one former astronaut agreed at a hearing on the issue. The U.S. Government Accountability Office said the Constellation program, scheduled to begin by 2015, is troubled by engineering, funding and mechanical issues. For instance, the program was meant to...
  • Hurler regains sight after 'miracle' diet supplement (macular degeneration)

    Former Cork club hurler Jimmy Aherne wept when he was told he would be blind within three years. The father-of-four -- who is a second cousin to hurling legend Christy Ring -- was diagnosed with age-related macular degeneration (AMD). The condition is cruel, as it has traditionally been untreatable. For decades, thousands of pensioners who lost their sight were simply told they had "old people's blindness" and that nothing could be done for them. But today, almost 12 months after that shocking diagnosis, the deterioration in Jimmy's eyesight has been halted and his good eye has improved to the point...

    The superhero power to see through walls will soon be within the grasp of ordinary mortals, thanks to a new hand-held X-ray scanner. Inventors hope the gadget could revolutionise police work and Customs searches by allowing officers to seek out contraband, weapons, bombs or hidden people. The LEXID device sends out low-level X-rays which are collected in a lens based on the design of a lobster's eye. Rick Shie, senior vice-president of its American inventors, Physical Optics Corporation, said that lobsters' eyes, which are able to see in deep, murky water, use thousands of tiny squares to focus by reflection...

    You are reading these words right now because 600 million years ago, an aquatic animal called a Hydra developed light-receptive genes—the origin of animal vision. It wasn't exactly 20-20 vision back then though. Hydras, a genus of freshwater animals that are kin to corals and jellyfish, measure only a few millimeters in diameter and have been around for hundreds of millions of years. Scientists at the University of California, Santa Barbara studied the genes associated with vision (called opsins) in these tiny creatures and found opsin proteins all over their bodies.

    When a 37-year old man walked into a hospital emergency room in Glasgow, Scotland last October complaining of "wavy" vision and a non-stop headache that had lasted four weeks, doctors were at first stumped, the British journal The Lancet reported today. The unnamed patient "had no history of head injury or loss of consciousness; his past medical record was unremarkable, and he was taking no medications . . . ." Body temperature and blood pressure were both normal, and a neurological exam scanned negative. But when an eye specialist was called in, the fog began to clear, at least for...

    Nearly 50 years ago, a young Greg Smith celebrated July Fourth fishing, learning to water-ski and getting sunburned on a favorite beach at the Salton Sea. Today, Smith is an Imperial County businessman working to help resuscitate the dying desert sea that few dare to enter and on bad days can drive visitors far from shore with its smell. “We've gone through the hand-wringing,” Smith said. “Now is the time to do something.” That something could cost $8.9 billion over the next 75 years. Legislation to launch a comprehensive revitalization plan – one of the most ambitious in the nation's...

    POLITICAL ILLUSION: When the supportive architecture of a democratic society is misinterpreted and subsequently portrayed to be tyrannically suppressive. POLITICAL VISION: The empowerment of officers in society to protect and serve all citizens’ liberties without infringing on existing democratic architecture. ESSAY: Optical illusions are visually perceived Images that trick our senses into seeing what may or may not exist. For example, Rubin’s Vase is a popular, two dimensional illusion. Indeed, it’s a perfect specimen to illustrate the major premise of this essay. For the uninitiated, the curves of Rubin’s Vase double as a silhouette of two opposing human faces. If...

    WASHINGTON, April 3, 2007 – Virtual reality made its way into the operating room last week when an Army doctor performed the military’s first three-dimensional minimally invasive surgery at Walter Reed Army Medical Center here. Armed with a state-of-the-art helmet, Col. (Dr.) Ernest Lockrow, director of the Telerobotics and Minimally Invasive Surgery Center, used the 3-D capabilities to perform a hysterectomy. Minimally invasive surgery, also known as laparoscopy, uses tiny incisions to operate and typically involves a telescopic lens that is connected to a video camera. The operation last week was the first time the military has used the...

    In the script Gov. Arnold Schwarzenegger recited this week during his trip to Washington, D.C., California is a nirvana where political parties have put aside their differences for the good of the people. "We reformed prescription drug costs, passed the world's most comprehensive plan to reduce greenhouse gases and began rebuilding the state's infrastructure," the Republican governor told a rapt audience of jaded political reporters at the National Press Club while he was in town for the National Governors Association Conference. "We did this working together." By following California's "post-partisan" model, Schwarzenegger said, President Bush and Congress could stop bickering...
