Testing

The new laboratory will provide comprehensive testing services for eyewear products to meet global regulatory requirements.

UL’s new eyewear testing facility in Shenzhen, China, received approval from China National Accreditation Service for Conformity Assessment (CNAS) to perform testing at the Shenzhen Eyewear Testing Laboratory.

The laboratory can conduct physical and chemical testing for eyewear products in accordance with the regulatory requirements of the global market. The tests help to ensure eyewear products meet the standards set by various countries in terms of quality and safety.

Eye conditions, such as shortsightedness, farsightedness, astigmatism and presbyopia, require corrective eyewear to help improve one’s vision. However, a range of problems, such as lab errors in the fabrication of lenses, incorrect prescriptions and poor eyeglass quality, can exist within the industry.

A review of customized eyeglasses carried out by the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China, found that nearly 30 percent of eyeglass products failed because of deviations in the vertex power of eyeglasses, one-sided horizontal deviations in the optical center or poor quality of the eyeglasses.

It is estimated that China requires more than 100 million pairs of eyeglasses annually with almost 30 million wearers falling prey to eyeglasses manufactured below the set quality standards. Wearing inferior eyeglasses may lead to eye fatigue accompanied by facial pain and headaches (asthenopia) and increased shortsightedness of the eyes. Additionally, wearing eyeglasses with incorrect lenses or poorly designed eyewear could lead to an imbalance of the eyeball muscles (strabismus) and/or a dimness of sight in one eye (amblyopia).

UL has set up Shenzhen Eyewear Testing Laboratory to help provide comprehensive physical and chemical eyeglass testing to help satisfy the regulatory demands of global markets. Global regulations for eyeglass quality are constantly being revised, with a series of screening tests required for the export of eyeglasses and other relevant products.

For physical testing, a full set of optical and mechanical capacity testing instruments are used, including: the haze tester, lens spectrograph, optical parameter tester, polarized light axis tester, xenon lamp tester, lensometer, high-velocity impact tester, eye shape tracer, tester for deformed bridge of the nose, tester for fatigue resistance, flame-proof property tester and so on. In terms of chemical testing, the Gas Chromatography-Mass Spectrometer (GC-MS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) which can help detect a broad range of indicators such as nickel release.

The testing methods cover permissible deviations in the size, sweat- and corrosion-resistance, material and surface quality of lenses, deformation of spectacle frame and retention of the lenses, the stability, wear, and flame-resistance of the size at a high temperature, optical degree, transmittance, scattering of wide angle, the level of nickel release, resistance to solar radiation, shock resistance of the lenses, data, labeling and the like.

UL is engaged in one-stop quality safety solutions involving testing, certification, verification, inspection, advisory and education, so that products can meet the unique requirements, regulations and standards of countries around the world, such as ISO, EN, ANSI, AS, GB, GB/T, ASTM, amongst others.

As an authoritative test and certification institution receiving international recognition, we are making continuous efforts to stride into new fields of product testing based on improving and advancing the established services. By doing so, we hope to lend a helping hand to a variety of enterprises, manufacturers and retailers in introducing their products into the global presence. With the ability to perform eyewear testing, UL will be able to cater to the growing demand for product quality in this industry in a more effective manner, be it the domestic or international market.” said Alvin Fung, Vice President and General Manager of UL Consumer & Retail Services, Asia Pacific.
