Why is the Varilux Ipseo lens design so outstanding?
The head/eye ratio is used to optimize the fields of vision and minimize the swim effect. This ratio influences two important surface design factors: A large foveal acuity zone for eye movements. A very smooth peripheral variation to improve dynamic vision and retain natural head movements. Every lens is calculated and designed to correspond exactly and precisely with the head/eye movement ratio measured and yielded from the individual coefficient.
