Spectacle Frames Testing

Eyewear Expertise – QC for Spectacle Frames

Despite the abundance of contact lenses and availability of corrective surgery, millions of consumers still choose spectacles as their vision correction device. For many users, spectacles are an important element of personal style, and an accessory they wear for most of their waking time. Quality, safety and robustness requirements for spectacles are high, due to the conditions of their use: prolonged contact with the skin; proximity to the eyes and face; exposure to such aggressive substances as sweat, perfume, and cosmetics.

Under European Regulation (EU) 2017/745, spectacle frames are categorized as a medical device for vision correction.
