Optical Lenses

Optical lenses are traditionally purchased by opticians and optical retailers, to be used in everyday optics, prescription sunglasses, driving glasses, custom-made reading glasses, and other types of prescription eyewear made to order. Compliance of ophthalmic lenses is paramount to the quality, performance and corrective properties of the finished eyewear.

According to European Directive 2007/47/EC, optical lenses are categorized as a medical device.

QIMA offers the full scope of lab tests and quality control procedures for optical lenses, including dimension, mechanical, optical, radiation, aging, and other tests. Our on-site factory inspections and HOKLAS accredited testing help you ensure that your product meets the requirements of your destination market and international standards.
