Throughout its years of presence in the Asian market, Essilor’s research and development centres have conducted extensive research regarding the physiological and behavioural differences between Asians and other ethnic groups. This research has proven that Asians are not only anatomically different from other ethnic groups, but are also unique in the way they are wearing their spectacles.

With recent developments in lens technology, lenses can now be designed digitally and with greater precision which leads to improved clarity and performance. However, the performance of a lens design still requires the spectacles to be worn with its required parameters to obtain optimal performance. Asian anatomical differences and their related wearing conditions have been addressed by Essilor’s latest customised lens design - Essilor® Azio360°™.

Essilor Azio360° now provides Asians with a lens that is designed and engineered specifically for Asian eyes. This breakthrough lens design takes into account the three key areas of visual experience that are unique to Asian spectacle wearers: Eye Anatomy, Facial Anatomy and Ergonomics.

The eye length of Asian eyes is generally longer. The centre of rotation is further away from the eye lens and the optical axis of an Asian eye tends to sweep over a broader area. Asians also have a less pronounced face profile and nose bridge and their visual experience is impacted by how the frame sits on the face.
