If you have lenses that are not curing on the edges, it usually is because of a dirty cure ring. The cure ring directs and amplifies the UV light towards the edge of the lens. Most users assume it’s a weak bulb. The wet edges will go away in some cases by replacing the bulb, but only because it’s putting out more energy. However this doesn’t address the underlying problem: the dirty cure ring. To clean the ring, remove it from the machine and sandblast the inside. If you don’t have Anti-Reflective equipment, you may not have a sandblaster. In that case Scotchbrite™ will work just as well. Note that the cure ring will not look shiny after cleaning, but the oxidation film build up from the chemical reaction during the cure process will be removed. This will allow the cure ring to better direct and amplify the UV light towards the edge of the lens for proper cure with less energy or new bulbs.

The above equation is an excellent way to think about how we run our lab, how we approach our business and what our employees are doing to help optimize our business. If you notice, there are no qualifiers like “good”, “bad” or “mediocre.” I’ll explain. In my first ever sales job my old and wise sales manager made me hang this equation on my desk and look at it every day. He said, while pointing to the equation, “While we can never control what comes after the equal sign, we can sure influence the heck out of it!” Good Performance + Good Activity = Good Results (over the long term for sure) while Mediocre Performance + Mediocre Activity = Mediocre Results — sounds pretty simple, huh? That’s because it is! Think about how you approach your process in making lenses and how your employees approach their work day — is there a daily performance plan? Are the activities which support that plan clear and manageable? If so, you should be getting good and consistent results. If not, your results will be indicative of mediocre to bad performance and activity. Set your performance for high, plan the activities that support it and watch your results mirror your performance and activity! Kevin Cross, Schneider Optical Machines

A common challenge for most labs is the need for continuous improvement: increasing efficiency and lowering overall cost per surface. Some seek outside, third party suppliers for low cost key processing materials such as diamond tooling and lens polish. While this practice may temporarily show a positive impact on unit cost by driving down initial consumable costs, in the long run it often has an overall negative effect on the bottom line. The first issue with this strategy is overall quality of the processing materials. In nearly every case your machine manufacturer has worked closely with their own suppliers to develop products and processes specifically tailored for their machines. While a third party vendor may offer a “like” product, chances are it has not been thoroughly tested and validated by the process designer. The result is usually seen in greater lens spoilage and/or machine issues that contribute to lower productivity and increased costs. In addition, having unknown variables in the process can hamper troubleshooting efforts when issues do arise. The best solution is working with your machine supplier to find the most economical process available that meets your lab’s specific needs. Most of them are working hard to develop new tools and techniques that provide greater flexibility and enhance your profitability. By taking this direction you are assured that your complete process has been developed and tested to work seamlessly with your machines. Ian Gregg, Satisloh
