Research & Development
With the launch of Varilux Comfort in 1993, Essilor developed the dioptric loop method, making it possible to gauge wearer satisfaction. It involves using repetition until an effective result is achieved for the wearer. It comprises five stages:
- Collection of the wearer’s physiological data
- Optical design
- Creation of prototype lenses
- Measurement control
- Clinical tests
In 2008, the Varilux Ipseo New Edition was designed using Essilor's Virtual Reality system.

Famous quotes containing the words research and/or development:
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
