Tipton Eyeworks: Inspired Designs and Quality Eyewear

June 7th, 2010

tipton5The foundations of Tipton Eyeworks were laid in the Seattle Washington workshop of Zachary Tipton when the young designer first began making custom rimless eyewear in 1998. For three years rimless designs were produced – all custom made – and various techniques were experimented with as new ideas took form. Some parts were hand forged from titanium welding rods and others were cut from solid material by the same machinists who make Boeing aircrafts.

In 2001 Tipton began experimenting with new ways to make a unique plastic frame. After testing many materials, from acrylic to polycarbonate, he hit on the idea of using vinyl records. The unusual texture and color of the vinyl made both the material and the concept practical, interesting and appealing to work with. During the first years of experimentation and production, Zachary’s father’s personal record collection suffered some serious damage, so as the business grew, old records were purchased and made into frames.

In 2002 Zachary moved to Hungary where he found a factory which was willing to develop a vinyl frame that could be mass produced. A special method of joining cellulose acetate with vinyl was pioneered and the Vinylize collection was born. Newly developed methods of machining, tumbling and thermal forming followed.

In 2004 Zachary was joined by his brother Zoltán and the first successful collection was made, consisting of four men’s styles and four women’s styles in a basic range of colors. Tipton Eyeworks was officially founded and finally moved out from under the radar. However, the Tipton brothers needed more vinyl to fuel their creations. Their source of material was secured when it was arranged for records to be pressed in a Czech plant near Prague. A friend provided the recording material – some very cool grooves – and a large portion of the pressings were donated to the band, sold or given away. The remainder was recycled into Vinylize products.

In 2007 Tipton Eyeworks began pressing their own records and today they work side by side with musicians. Their recordings are mastered, cut, and then pressed and the albums are distributed across Europe, Southeast Asia and North America. The records that remain are recycled into Vinylize frames. In this manner, Tipton can guarantee the release of otherwise unheard music…and an ongoing supply of ready-to-use vinyl from which to construct their frames.

Later the same year Tipton Eyeworks released a new line of eyewear featuring celluloid film strip mounted in the temples. The Cinematique line is a combination of cellulose acetate, stainless steel and authentic 16 and 35mm film strip. This range continues Tipton Eyeworks’ unique take on eyewear, playfully re-contextualizing concepts of sound and vision with frames that make a statement as well as serving a function.

Today, Tipton Eyeworks continues to produce inspired designs and quality eyewear, cementing their reputation as a dynamic creator of edgy concepts and a superior finished product. These days the focus is on creating bold new design concepts while constantly working to improve the quality and functionality of their pieces.

Computers Can Help Detect Diabetes Related Eye Problems

June 7th, 2010

People with diabetes have an increased risk of blindness, yet nearly half of the approximately 23 million Americans with diabetes do not get an annual eye exam to detect possible problems.

But it appears that cost-effective computerized systems to detect early eye problems related to diabetes can help meet the screening need, University of Iowa analysis shows.

The UI team compared the ability of two sets of computer programs to detect possible eye problems in 16,670 people with diabetes. Each of the two programs (known as EyeCheck and Challenge 2009) are based on technology developed at the UI and performed equally well, achieving the maximum accuracy theoretically expected. The study was published online April 16 by the journal Ophthalmology.

The systems require a trained technician to use a digital camera to take pictures of the retina, located inside the eye. The images are then transferred electronically to computers, which can automatically detect the small hemorrhages (internal bleeding) and signs of fluid that are hallmarks of diabetes damage.

“It is an important question: whether a computer can substitute for a human to detect the initial signs of diabetic eye disease,” said Michael Abràmoff, M.D., Ph.D., associate professor of ophthalmology and visual sciences at the UI Roy J. and Lucille A. Carver College of Medicine and an ophthalmologist with UI Hospitals and Clinics.

“Our analysis shows that the computerized programs appear to be as accurate and thorough as a highly trained expert in determining if these initial signs of an eye problem are developing in someone with diabetes. Once the initial problems are found, an eye specialist can treat the patient,” added Abràmoff, who also is an associate professor of electrical and computer engineering in the UI College of Engineering.

To explain the system’s efficiency, Abràmoff said that among a group of 100 patients with diabetes, 10 people would likely have diabetes-related eye problems. An ophthalmologist (eye doctor) would have to check the eyes of all 100 patients to find out who had problems. The computer programs, when given photos of the eyes of the same 100 patients, flag on average 20 people as possibly having diabetes-related eye problems. Thus, an ophthalmologist would need to see only the 20 people prescreened by the computer program instead of the original 100.

“The computerized programs are accurate and allow ophthalmologists to spend time on patients who actually need care and provide better care to those patients. Also, through this technology, people with diabetes can have an opportunity for screening that they might not otherwise have,” Abràmoff said.

Abràmoff noted the study had some limitations. For one, the images were prescreened to ensure the computers could analyze them. However, his research group has already developed the tools to automatically ensure adequate image quality before proceeding.

In addition, the number of people in the study who actually had diabetes-related eye problems was lower than what might be seen in other populations, such as people whose diabetes in not under control. Thus, Abràmoff said, it will be important to test the systems in other, larger groups. Last, the computer-based assessments were compared to assessments done by only one human reader at a time, which may not reflect a comparison to assessments by multiple readers.

“A computer alone will never be a substitute for the care of a good doctor, but it’s exciting to think that computers can be partners in finding the patients at risk of blindness who should see an ophthalmologist,” said study author Vinit Mahajan, M.D., Ph.D., assistant professor of ophthalmology and visual sciences.

“In the United States alone, between 40 and 50 percent of people with diabetes are not getting the eye screening exams they need. We think these detection programs can meet this critical need very cost-effectively,” Mahajan added.

Abràmoff holds a patent, as well as patent applications, on the technology used in the study, and is one of the owners of the EyeCheck project. Study authors Meindert Niemeijer, Ph.D., UI research scientist, and Gwénolé Quellec, Ph.D., UI adjunct research scientist, hold patent applications on this technology, as well.
