October 2019Last July, I was invited to present CCCES Glasses to an independent dental product testing group. In August they sent out 20 pair of glasses to different dental offices to be tested and reviewed. The result of those findings will be featured in their monthly publication.
Basically, CCCES Glasses earned an 80% acceptance rating from the evaluators and 85% said they would recommend CCCES Glasses to their colleagues. The testing also confirmed that the commonly used Cavi-wipes, containing isoproyl alcohol, found in most dental offices could be used as a disinfectant with no damage to the scratch resistant coating. However, the ethanol alcohol in Lysol would remove the coating and should not be used on the glasses especially in high concentrations.. As of yet, glutaraldehydes used in cold sterile have not been tested; but most likely could be used as a sterilization method. For our own testing, the brand Optim Wipes with hydrogen peroxide was repeatedly used for 8 months with no adverse effects on the coating. We are extremely appreciative of everyone who contributed to the testing. We intend to use this information to improve CCCES Glasses to be even a better solution in not only protecting your patients with effective safety, but also by making your work load less complicated.
The progress continues...please note the material description below. The knowledge and expertise of Stephen Chen of Arclite Optics has made this simple idea of tweeking regular glasses to the reality of an effective and safe product for CCCES Glasses. An order has been placed that should be fulfilled by the first of August. It will include a slightly darker copper colored lens, a gray lens, a light blue lens, and a clear lens. (Of course, our hope for the nitrous nose fitting glasses is still in our future plans.) This is in response to the requests we have received. Please continue to send us feedback as we strive to provide the best solution for the needs of your patients.
Material Data and Description
The CCCES protective eyewear gasket seal is molded from flexible PVC material. Flexible PVC is commonly used in the Medical Device industry for its excellent durability, chemical resistance, weather-ability, and low maintenance. PVC is easily sterilized and holds up to repeated use with excellent resistance to scratching, tearing, cleaning fluids and permanent deformation and discoloration under normal use. The biocompatibility of PVC is characterized as high.
High Performance Ultra Durable Nylon 6,6 is used in the construction of CCCES frames, making CCCES frames unbreakable in even the most rigorous of end-use conditions. The Nylon 6,6 used in our eyewear is the same frame material commonly used in military eyewear applications where durability, chemical resistance and the ability to withstand extreme conditions are required. These performance attributes give CCCES frames an extended lifespan by ensuring there is no drop-off in head retention, comfort or protection after repeated use.
The CCCES lens's substrate material is molded from high molecular weight optical polycarbonate. This material is also commonly used for military ballistic lenses designed to provide protection against high-speed projectiles. High Molecular Weight polycarbonate has long polymer chains that prevent the material from brittle fractures upon impact. The Resin used in CCCES lenses provides excellent optical performance, 100% UV protection and military grade impact protection.
The best hard coatings available in the optical industry protect CCCES lenses. These coatings are also military grade and hold up to extreme levels of wear in the harshest environments. They have excellent scratch and chemical resistance, and are easily cleaned and sterilized, even after repeated use.
We did make it to the UDA convention with the Cadre (meaning framework) our first pair of safety glasses for our dental patients. We appreciate everyone who stopped by our booth and those who even bought a pair of glasses. We hope to be able to meet your needs and provide the best fit, function, and a little fashion to supply this important safety for your patients. Thanks for your interest and support!!
Design is completed and molds are being constructed. We have a promise of a product by April 15th and have made plans to attend the UDA Convention April 25-26, 2019. Watch for a post of the completed product to post shortly.
On schedule and moving forward!! Below is a prototype of the new design we are working on. Thanks again to all the dental offices that allowed me to come and take pictures of their headrests.
October '17-March '18
Thanks to all those who bought and tried a pair of glasses; your feedback was extremely helpful to detect the need to redesign the glasses according to optical specifications. In our research to solve the problems with our initial design, we followed a number of referrals that led to Stephen Chen of Arclite Optics. He has since consented to work as a consultant on the project. With his experience in the overall business of providing specialty safety glasses, and his contacts with a designer with significant eyewear experience and a long term manufacturer of protective and medical eyewear with cutting edge technical capabilities, we will be able to move forward finding the best solution for CCCES Glasses. Our present timeline will be to have a new design of separate frames within the next 2-4 months, and the production of not only the regular style glasses but also the nitrous nose style by the end of this year.
Assembly of the glasses and preparations 'for sale' are completed. The first promotion of a medium-large adult size in shades of copper and blue are available. Please visit our Store to place an order. (As you put CCCES glasses to the test, your comments will be greatly appreciated so that we can make adjustments on the next molds to create the best possible solution to provide your patients with the ultimate protection in safety glasses.)
Search for the resin that would provide the best clarity, strength to meet ANSI/ISEA Z87.1-2010 standards, be resistant to chemicals used to sterilize, and be extremely scratch resistant was an arduous task. Presently, we have copper glasses made from Skygreen PCTG, and blue glasses made from Triton resin, both of which meets the above criteria better than polycarbonate. However, the search for a higher grade resin still continues and will be offered as soon as possible.
We worked with International Industry, LLC of Whippany, NJ for the production of the mold. The mold was actually milled in China and after repeated polishing to create clarity in the resin, it took a month for the mold to travel across ocean to the US
After several adjustments, our final prototype is being printed and should prove to be the correct fit. We have also developed a model that will accommodate the Nitrous nose piece effectively. The purchase order for our first mold was sent to Hubert Zheng, International Industry, LLC, on October 7, 2016.
|4th and final prototype|
We were hoping to combine two lens pieces in one mold, unfortunately, that doubled the cost. The CAD file is already to go, therefore, we will be offering the nitrous model in our second promotion.
At the completion of the CAD file, estimates for the cost of the manufacturing of the molds will be available. This has proved to be a meticulous job in converting an idea onto paper with all of the correct curves and angles.
After endless attempts to contact large manufacturing companies of safety glasses, and even sunglasses, it became evident that a different avenue would need to be taken. Consequently, Gary Murdock of Technology Design provided insights to plastic injection fabrication. His confidence that this was a workable project was very reassuring.
How It's Made: Plastic injection molding 4:49
However, before the molds can be made, a CAD file needs to be drawn up by a mechanical designer. These are 3D images prepared by Bart Storrs of Pro3Design. His patience, as he tries to walk me through this process, has been commendable.
Our goal is to create a monolithic structure that raises above the patient's eyelashes, closes in the gaps below by the cheeks and at the sides, has shortened temples that do not hit the headrest, and is made from a resin that will not be affected by alcohol.
The patent attorneys of Pate Baird were very helpful and encouraging too. They began the process of obtaining a provisional patent for the concept of:
Customized Client Care Eyewear Solutions
According to the Patent Pending terminology this is:
One embodiment of dental protective eyewear; for example, and not by way of limitation!
