Optimize your lens with Dai Optical

Improve your free-form progressive lens with the DSX process for right- and left-handed people The research, development and innovation center (RDIC) at D.A.I. Optical has developed a new manufacturing concept and thanks to a skillful process industrialization it has created DSX optimization. DSX is an optimized design for right- and left-handed people that can be applied to any free-form progressive lens (DIVA IAD - DAITACH - DAITACH STAB - DAITACH PLUS). The process, which takes into consideration the hand preferred for everyday activities, further personalizes and, above all, strengthens the progressive lens. DSX improves the progressive channel, increases the reading zone by 20% to 35% (based on the progressive design chosen), delivers comfortable vision at all distances and a natural posture for everyday activities.   When we use a mobile device (tablet, smartphone, cell phone, notebook or smart pc), when we read a book or write a letter, we all have different postures depending on our manual laterality. For example, when we write we turn the page to the right or left, when we hold a book or smartphone we turn the barycenter toward the relevant side, we perform innumerable actions with an asymmetric posture that is dictated by our preference for one hand or another. Clearly, this also influences vision: right-handed or left-handed people never use the same reading zones.   Vision and posture are correlated and a change in vision function frequently coincides with a change in posture and vice-versa. When we move our eyes we transmit incalculable data to the head muscles which allow us to find the best posture for focusing on an object. Obviously, this posture is conditioned by our laterality - in other words, the predominant right or left side of our body.   Thanks to DSX optimization, the progressive lens takes laterality into consideration and adapts to it. Therefore, wearers have a wider near vision field, the progressive channel is more fluid and vision is free at all distances.   DSX technology can be applied to any free-form progressive lens to perfect intermediate and near zones by means of an additional map that recalculates the progressive channel and, as a consequence, widens the field of vision without altering the properties and technical characteristics of the chosen lens.
