At onepointsenfour we recognise that each eye has a different shape and size. Based on an eye measurement with our DNEye Scanner, the biometry of the entire eye is determined for the calculation of the lens (several thousand data points and amultitude of parameters of each eye). This biometric data is incorporated directly into the lens production process, which is unique in the industry. The result: the most precise lenses in the world, with the sharpest vision for every angle and every gaze.We call these lenses B.I.G. EXACT. B.I.G. stands for Biometric Intelligent Glasses: these lenses marked the beginning of the biometric era at Rodenstock and B.I.G. VISION FOR ALL has become our philosophy.Unlike traditional measuring devices, the DNEye Scanner not only records the standard values for myopia (short-sightedness) and hyperopia (long-sightedness) and corneal curvature, but far more – e.g. the reaction of your pupil during the day and at night as well as the corresponding changes in vision. This way individual aberrations are also detected, which are responsible for reduced contrast sensitivity and poor vision at twilight, for example.
