WHY ASSESS THE QUALITY OF RAW MATERIALS IN THE LABORATORY?
Among the activities and controls that are done in an optical laboratory, it is now essential to value in money, resources, time among others how much it represents using raw materials of low quality. In many cases, due to financial reasons, a supplier with very low prices is chosen, but for obvious reasons, the quality is not the best.
When the optical laboratory was of conventional technology, the accuracy, and type of machinery did not meet the high standards as today’s, which make the work more and more precise. With the arrival of sophisticated machinery as Free Form generators, the wear of the cutting pieces and the maintenance costs are figures that only a few owners/managers consider and transfer to the actual cost of raw material. However, low quality of raw materials requires decreasing in generator velocity. The clear picture reflects actual high costs in terms of maintenance, wear of equipment, labor costs. In such a case, the cost saving will not be as expected…
Now, if we talk about the final result, quality wise, we scarify optical quality for profitability improvement of your optical laboratory. The homogeneity in the curves of the surfaces and in the scripts that have the OPC codes (Optical Product Code Council, Inc.).
minimize the possibility of human errors (when typing in the LMS – Laboratory Management System ), allow the generator to work with raw material in an optimal way and ensuring that the personalization of each product is really what is offered to the client. Any of these variables, a few years ago, were not a necessity. However, some optical laboratories continue to work with suppliers that do not take this into account and as a result, the lenses that are being delivered do not have the quality requirements, demanded by the market at this time.
The protection against UV radiation is also another issue that in many cases is not taken into account, in some cases, the monomers used to manufacture the lenses (spectacles), bases and/or the finished lenses, do not have the same capacity to protect from the harmful spectrum of UV light.
In the market, there are lenses (bases and/or finished lenses) that do not have any type of protection what so ever, these lenses can be attractive for some optical laboratories, which mainly focus on the short term because of their low cost. Of course, in order to guarantee good protection, it is necessary to use good quality inputs and for this reason they are more expensive. Knowing not all lenses (spectacles) are equipped with the same characteristics is indeed important.
We learned that in some optics stores there is no equipment capable of measuring the amount of protection and this is not one of the characteristics ophthalmologists and opticians, usually take into account in the process of accountability to their patients. With more market know-how we will unleash a process that will create awareness and eventually, due to market higher standards, will force the local and regional optical laboratories to embrace higher standards of quality control of the glasses (spectacles).
Based on statistics, we found it hard to find a professional client who testifies he prefers risking quality over price unless the budget is the only parameter that affects the decision. Bottom line, the client always approaches an optical laboratory to SEE BETTER…
