Old-fashioned 3D is not an oxymoron.

Stereoscope

With all this chatter about 3D technology, let’s take a time out and talk old-fashioned 3D. And by old fashioned, I don’t mean “real life,” or the blue/red Creature Feature 3-D cinema from the ‘50s and ‘60s, or even the View-Master. I’m talking about stereoscopes—which, according to the ever-accurate Wikipedia, display images in 3D by “by presenting a slightly different image to each eye.”

When I was a kid, we had a hand-held stereoscope from the early 1900s around the house. The stack of dual-image postcards that you used with the stereoscope was tattered and full of subject matter that was probably most interesting a century ago: dressed-to-the-nines ladies in carriages, family photos, and bizarre still lifes. But the sepia-toned images never failed to amaze me. They transported me back to a time I could barely imagine…carriages? Hoop skirts? Model Ts?

Considering the amazing technological advances that have happened just in my lifetime, I wonder if Sir Charles Wheatstone, the inventor of the stereoscope, had any inkling of what was to come.

What technologies do you think are the stereoscope of 2011? And where do you see those going?

3D helped defeat the Germans in World War II

Guest blogger Dave Johnston works in VSP’s marketing department and shares with us a fascinating article about the implementation of 3D technology in WWII.

With the recent advancements in 3D technologies in both the movie and gaming industry, it is hard to believe that 3D technologies played a part in World War II. That’s right, World War II.

A recent BBC News Magazine article by Jon Kelly explains how the Royal Air Force used aerial photographs taken by low flying, un-armed Spitfires and a stereoscope to map out the landscape in enemy territory and disable key German missile installations.

“To make the 3D effect work, images had to be captured in carefully-plotted sequences which would overlap each other by 60% so everything would stand up when viewed through the stereoscope.”

It explains how the outcome of WWII could have been very different if the Nazi’s had managed to carry out planned attacks on London using the newly developed V-1 and V2 missiles.

The stereoscope allowed users to measure the height of landscapes and identify hidden structures, such rocket launch sites.

Do you ever experience red or watery eyes, blurry vision or have difficulty focusing after an eight-hour day at work? Together these symptoms may result in computer-related eye problems, but someone can have them without working on a computer. The patients that come to my office often have physical and visual symptoms resulting from an office work environment. Here are some common symptoms and possible solutions to help your eye health during work.

Dry Eyes – Due to ventilation systems, dry air, dust or printer toner in the air, tears may not adequately coat and moisten the eye, leading to red, burning, or irritated eyes. When reading or using the computer, people tend to not blink as often, compounding the problem.   

Solution: Blink more when reading or working at the computer. Your optometrist can evaluate and treat dry eyes if it’s a chronic problem.

Workstation Design Problems – If a person’s desk, chair, keyboard and computer monitor are not oriented properly, it can lead to rapid visual fatigue.

Solution: Place the screen 24 inches or more away from your face, and make sure it’s directly in front of and slightly lower than your eyes.

Visual Focusing Problems – The strain on your eyes when focusing on paper or a computer screen can become fatiguing over time. Some people have visual focusing and coordination problems that make reading or using a computer uncomfortable or cause headaches.

Solution: Take frequent breaks (20-20-20 rule: after 20 minutes of computer use, look at something 20 feet away for 20 seconds).  You may also benefit from specific glasses prescribed for office work that help you focus at the correct distance.  

If you experience symptoms such as red, irritated, burning eyes, headache or visual fatigue while at work, make an appointment with your VSP Vision Care provider. Effective treatment can include modifying your work area, using the proper prescription glasses, eye medications, or a program of therapeutic visual activities, referred to as vision therapy. One or all of these may be needed to keep your eyes and vision healthy and productive at work.

Dr. Phelps talks with Forbes about Computer Vision Syndrome

VSP Provider Dr. Roger Phelps served as the subject matter expert on Computer Vision Syndrome with Forbes.com in a recent article titled: Do Computers Really Fry Your Brain? Here is a snippet of the interview with Dr. Phelps and Forbes writer Jenna Goudreau. 

In 2005, a medical term was coined to diagnose some of these problems, now known as Computer Vision Syndrome (CVS). A review of the syndrome in the Survey of Ophthalmology, a peer-reviewed journal, calls it “a repetitive strain disorder that appears to be growing rapidly, with some studies estimating that 90% of the 70 million U.S. workers using computers for more than three hours per day experience it in some form.”

If you spend several days a week gaping for hours at a computer screen, you’re likely familiar with the symptoms. Eyestrain and eye fatigue, irritation, blurred vision, head and neck aches and nausea can all be associated with prolonged computer use.

“People are sitting in front of a computer all day,” says Ojai, Calif.-based optometrist Roger Phelps, who has been practicing for decades. “You are looking at a light source, not focused at the proper distance, and staring. It causes strain.”

Phelps believes that the damage caused by CVS is temporary and can be reversed. The main issue, he says, is that people tend to stare at electronic screens, not blinking or looking away as often as they might while reading a book or magazine.

Why do we stare? Phelps thinks that the technology, from gaming to surfing, is inherently more interesting–colorful and fast-paced–so we don’t want to miss a second. Staring at screens commonly leads to dry eyes, which he sees in more than one-third of his patients and says worsens with age.

Phelps suggests using eye drops and adhering to the 20-20-20 rule, which stipulates that after 20 minutes of computer use, you should look at something 20 feet away for 20 seconds. The break will allow your eyes a rest and a chance to refocus.

Developing: Artificial muscle promises to restore the ability to blink, most likely will progress to winking ;-)

eye blink illustrationVery interesting stuff. EPAM – Electroactive Polymer Artificial Muscle, is currently working its way to human implantation (within 5 years). From the article:

Surgeons from UC Davis Medical Center have demonstrated that artificial muscles can restore the ability of patients with facial paralysis to blink, a development that could benefit the thousands of people each year who no longer are able to close their eyelids due to combat-related injuries, stroke, nerve injury or facial surgery.

For people with other types of paralysis, the use of artificial muscles could someday mean regaining the ability to smile or control the bladder. Reanimating faces is a natural first step in developing synthetic muscles to control other parts of the body, said UC Davis otolaryngologist Craig Senders.

If you have the slightest interest in medical technology or just want to see how hard researchers are working – I HIGHLY recommend reading this article. Go humans!

Hi James Cameron, I liked your movie – so here’s a 3D medical application.

TrueVision Systems, Inc. is helping budding ophthalmologists in the operating room by providing a new tool to help observe surgeries. The Santa Barbara CA based company is offering “3DHD” – a technology that projects a 3D image from an LCD screen (think Avatar the movie – hence the James Cameron reference). Its initial design is most beneficial for instructional purposes. Residents and students are able to observe delicate surgeries enlarged in great 3D detail, of course with the help of polarized 3D glasses.

Check out their page for a video in the operating room. Drew Carey bonus points if you know the bands playing in the background, I’ve got the song titles – Amber and Facedown. I’d like to hang with these MDs, they know good music.
