SUNGLASSES TESTING SERVICES FREQUENTLY ASKED QUESTIONS
-
My client bought a pair of sunglasses and complained about the discomfort of wearing it. I checked the sunglasses and found that it has a perfect filter surface and the frame is good. What could be the root causes for this discomfort?
The discomfort may be caused by the optical imperfections of the sunglass filter that cannot be detectable by visual check. Resulted from manufacturing defect, sunglass filter without corrective effect is classified by three optical classes according to its spherical, astigmatic and prismatic:
• Class 1 is the best quality class to aim for.
• Class 2 is common quality and acceptable for general use.
• Class 3 is not recommended for permanent use because of noticeable optical imperfections.
