LAS VEGAS — Here at International Vision Expo West, Essilor of America introduced Varilux DRx lenses, which combine the Varilux design supported by wearer testing, Essilor semi-finished single vision lenses and Essilor's proprietary Digital Surfacing Process Control.
These lenses were tested on actual wearers at each stage of lens design, according to a company press release. "The Live Optics process creates a lens design that more accurately complements the human eye," the press release stated.
Product availability will include Varilux Physio DRx, Varilux Physio Short DRx (14 mm to 17 mm), Varilux Comfort DRx and Varilux Comfort Short DRx in 1.50 index plastic, 1.50 Transitions VI, Airwear polycarbonate and Airwear Transitions.
Essilor also announced the Visioffice system, described by a company press release as a state-of-the-art measuring device that provides eye care professionals with a fast, accurate way to measure patient fitting parameters critical to the next generation of lenses. The device takes all standard eye measurements and exclusive Essilor measurements, including behavior measurements for Varilux Ipseo lenses as well as eye rotations center and natural head posture measurements for Eyecode lenses.
The company also debuted the Eyecode lenses, which, Essilor says, offer patients the most precise vision possible no matter where they look through the lenses. Through a dynamic three-dimensional measurement, the exact position of the eye rotation center (ERC) is measured, providing a new reference for pupillary distance and fitting height.
According to a company press release, the Visioffice system replaces an approximate vertex distance with the distance between the ERC and the lens, called the eye rotation center distance (ERCd). These three measurements, pupillary distance, fitting height and ERCd, build the unique code for each eye, forming the foundation of lens individualization based on the physiology of each wearer.
Essilor also announced the availability of Varilux Physio enhanced Fit and Essilor Fit Single Vision, which offer personalized measurements for pupillary distance, vertex distance, pantoscopic tilt, wrap angle and fitting height.
