The lens design with B.I.G. EXACT™ Sensitive varies with each individual, according to Rodenstock: the lenses for people with high visual sensitivity feature smaller, more concentrated aberration fields. They provide up to 42% larger aberration-free zones, that reduces the potential for vision disruptions. The lenses optimised for people with low visual sensitivity have more evenly distributed aberration fields. The low sensitive design offers up to 30% reduced peripheral aberrations and softer transition zones, which provide the wearer with a more seamless vision flow.
Rodenstock conducted trials and an eye tracking study to prove the efficacy and success of the new B.I.G. EXACT™ Sensitive lenses. The spectacle wearers in the trials strongly preferred the new lenses. On average, they experienced notable improvements such as 28% better reading flow, that means that the process of reading undisturbed was improved. The participants stated a 24% improvement in vision flow as the transitions between vision zones in the lenses and varying vision distances were perceived as seamless.
“Biometric lenses are one of the few real paradigm changes in the ophthalmic lens industry of the past two decades”, said Dr Dietmar Uttenweiler, Executive Vice President Innovation.
