Launched in the UK in June 2023, the Varilux^® XR series™ – the best Varilux progressive lens ever ⁽²⁾ – harnesses the power of behavioural artificial intelligence (AI) to deliver the first eye-responsive varifocal lens ⁽³⁾.

EssilorLuxottica’s Research & Development team used more than one million data points collected from exclusive real-life wearers. These data insights were supported by the creation of a digital twin to replicate a patient performing multiple realistic visual tasks in a 3D environment. This innovative research and development resulted in the design of a varifocal lens that respects the natural behaviour of the eye, capturing the exact detail that wearers need their lenses to deliver.

By predicting the visual behaviour of the patient and bringing binocular optimisation to the next level, EssilorLuxottica’s XR-motion™ technology reduces the optical disparities between the two lenses and ensures precise positioning of the focus zones adapted to each wearer. Both lenses are optimised binocularly according to the predicted visual behaviour profile to simultaneously provide better positioning of the near vision zone and optimised sharp binocular vision. Varilux^® XR series™ lenses therefore offer instant visual sharpness even in motion ⁽¹⁾, with natural ocular navigation.

Meeting the modern challenge

Today, a plethora of screens and smartphones demand our attention – on average we receive around 80 notifications each day ⁽⁴⁾. As a result, our eyes are moving over 100,000 times a day to process all this visual information ⁽⁵⁾. All this activity forces varifocal lens wearers to ease their head movements and causes more difficulty to maintain visual sharpness. To address this very modern problem, Varilux^® XR series™ designers combined the power of behavioural AI with a study of more than 6,500 consumers to enrich their understanding of presbyopes’ lifestyles and visual challenges. Varilux^® XR series™ lenses offer wearers instantly sharp vision even in motion– that is, seeing things clearly at all distances and feeling reactive and stable, even when they are “on the go” ⁽¹⁾.

Beyond XR-motion™ providing better positioning of the near vision zone, Varilux^® XR track and Varilux^® XR pro lenses offer a further personalised element by incorporating Near Vision Behaviour (NVB). This measurement takes into account the wearer’s visual behaviour, while they replicate a reading task. This then positions the reading zone according to the patient’s natural behaviour and results in an extended near vision width. This NVB measurement is made of four elements: the reading distance, the lateral offset, the visual behaviour and the gaze lowering of the presbyope. With this measurement, EssilorLuxottica can truly understand the presbyope’s profile and provide them with the best possible vision and an enhanced comfort.
