I’m always on the lookout for new research that help us better understand human vision as well as how to preserve and protect it. One study that caught my attention recently concerns a team of researchers at Purdue University
who discovered that the circadian clock plays a significant role in protecting eyes from retinal degeneration. The team studied fruit flies, which serve as a good model for the human retina. In a recent interview with Purdue writer Elizabeth K. Gardner, team leader Vikki Weake, associate professor of biochemistry in Purdue's College of Agriculture, discussed how it might be possible to slow or prevent vision loss from retinal degeneration.

Most ophthalmologists and optometrists are probably familiar with optical coherence tomography (OCT), the non-invasive imaging test that uses light waves to take cross-section images of a patient’s retina. However, OCT is being applied in new ways that might surprise even the eyecare professionals who use it in their everyday practice. Duke University recently announced that researchers there are now applying lessons learned from decades of perfecting the eye imaging technology to autonomous systems sensor technologies used in robots and vehicles.

Biomedical engineers at Duke University
have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The gold standard for imaging and diagnosing diseases within the retina, OCT has yet to find widespread use as an imaging technique for other parts of the body due to its inability to return clear images from more than a millimeter beneath the skin’s surface. Duke researchers found that tilting the light source and detector used in the technique increases OCT’s imaging depth by almost 50 percent, putting skin diagnoses within reach. The “dual-axis” approach opens new possibilities for OCT to be used in applications such as spotting skin cancer, assessing burn damage and healing progress, and guiding surgical procedures.

NEW YORK—If the term “smart glasses” still conjures up images of Google Glass for you, it’s time you took another look at them. Smart glasses have come a long way in the eight years since Glass’s brief but controversial run as a consumer product, which ended due to its unconventional styling, high price and privacy concerns related to its onboard video camera.

Calling the James Webb Space Telescope
an "eye in the sky" barely hints at its power, precision and vast capabilities. Launched by NASA in December, 2021 following years of research and development, and an investment of $10 billion, the Webb Telescope is by far the most sensitive and sophisticated instrument of its type ever developed, a pinnacle of scientific achievement. Its ambitious mission, to peer into space and provide clear images of distant planets, stars and whole galaxies that are light years away from Earth, is unprecedented in scope and complexity.

Starting with the launch of Google Glass in 2013, tech giants such as Google, Meta and Amazon have been exploring ways to make eyeglasses a vehicle for their consumer technologies. A prominent example is Ray-Ban Stories, which features a Ray-Ban frame with camera and audio capabilities and is the result of Meta’s collaboration with EssilorLuxottica.

Growing up listening to rock ‘n’ roll radio, I always had my ear tuned to the weekly Top 10 countdown. For many of us Boomers, those hit songs, selected on the basis of radio airplay across the country, were the soundtrack of our youth. As enjoyable as it was to hear these hits in descending order, with the #1 song played last to goose the excitement, I often found myself disagreeing with the ranking. Why was my favorite song #4 on the chart, not #1? These and other burning questions made me question the Top 10 ranking. I knew I could it do better if I’d only had the chance. So, with the new year fresh upon us, I figured it’s a good time to create my own Top 10 list. But instead of songs, I’ve assembled a list of my 10 favorite Today’s Read stories from the past year. I hope you enjoy my look back on these features.

New contact lens technology to help diagnose and monitor glaucoma and other ocular health conditions may soon be ready for clinical trials. A team of researchers from Purdue University
worked with biomedical, mechanical and chemical engineers, along with clinicians, to develop the novel technology. The team enabled commercial soft contact lenses to be a bioinstrumentation tool for unobtrusive monitoring of clinically important information associated with underlying eye health conditions. “This technology will be greatly beneficial to the painless diagnosis or early detection of many ocular diseases including glaucoma,” said Purdue’s Chi Hwan Lee.

NEW YORK—Attendees of the final Vision Monday 2021 Summit got a glimpse of the metaverse and a quick tutorial about the intriguing possibilities this new digital world offers businesses, brands and healthcare. A previously obscure realm of cyberspace known mostly to video gamers, techno-nerds and digital content developers, the metaverse has been enjoying a breakout moment lately as high-profile entertainers, fashion and lifestyle brands and other early adopters have begun using it to engage consumers in imaginative new ways.

What makes a man take on an assumed name and a new identity? There are many reasons. For instance, maybe he’s a criminal who is evading the law, or is in a witness protection program. Perhaps he’s a con man, or even a spy. Or he could be suffering from dissociative disorder. Then again, he might be a performer using a stage name, or a writer doing business under a pen name. The possibilities are vast. I recently learned that the man I’ve known for years as Dick Paul has crafted a new name and persona for himself. Many readers probably know him as a successful independent optical sales rep. Lately, Paul has been showing a very different face to the world, that of Desmond Drue, an accomplished novelist, poet and screenwriter.

BOERNE, Texas—Two years ago, Eyes on Main in Boerne, Texas, became one of the first Zeiss customers in the U.S. to get a Visufit 1000, the company’s advanced measuring and dispensing system. Although the technology was new to Eyes on Main, practice owner Loren Rodgers, OD, an ocular disease, vision rehabilitation low vision specialist, was confident she had made a good investment. “We were utilizing the Zeiss iTerminal Mobile, which is another outstanding measuring device, but after previewing the Visufit 1000 we knew it would be a wonderful asset to the practice.”

The term “work in progress” accurately defines most prescription optical laboratories. No matter how smoothly a lab may be running, there’s always something that needs updating or replacing, whether it’s adding a single piece of equipment, reengineering an entire production line or even building a whole facility. It’s an endless cycle of invention and reinvention, and labs must learn to adjust to it while continuing to service customers, a challenge which can be daunting for any business.
