Since 1959, the research and development of the ophthalmic industry worldwide has been in search of the "perfect progressive lens.".

In 1959, when the first progressive lenses with conventional manufacturing technology (anterior face molding design) were launched, they had a ratio of approximately 2dpt of cylindrical aberrations per power addition.
In those early days, progressive lenses were difficult to fit because they did not provide the necessary comfort for patients. Then, scientific research groups have continued to advance to improve progressive lens designs.
In 2006, Freeform production technology became popular, which gave rise to lenses created with digital designs, customized and manufactured on the back side. In this line, novar launched in 2016 a worldwide technological breakthrough called Continuum Design Technology© (Patent Pending) that was a qualitative leap in improving the optical definition of lenses and achieving instant adaptations for Patients due to obtaining an average ratio of 1dpt of cylindrical aberrations for each power addition.
