Why are head/eye movements so important?
The swim effect of progressive lenses is mainly due to head movements, while, at the other end of the spectrum, the more a wearer moves his eyes, the greater the lens area the eyes explore. So in order to optimize a progressive lens, it is essential to know the patients unique vision strategy. All Varilux lenses are based on the wearer’s physiological needs. The designs of the first five generations of Varilux lenses have been constantly improved based on the common fundamental needs of large populations of presbyopes. Today, Varilux Ipseo lenses consider the individual physiological differences of each and every lens wearer.
