Essilor X Series

Essilors’ X-series are Barnabys varifocal of choice.

Benefits from exclusive technologies. Essilor overcomes the lens compromise between fields of vision and swim effect. Wearers benefit from ultimate vision due to three revolutionary advances in optics and the knowledge of wearer physiology.

Nanoptix entirely reengineers the fundamental structure of both lenses to reduce the “swim” effect. As both base curve and power impact the beam deviation, their combination is optimised for each element. Swim effect is reduced by up to 90%.

Synchroneyes takes into account the physiological differences between the two eyes to ensure maximised fields of vision. Each lens optimisation integrates the differences between the right and left prescription as well as the distance between pupils and Binocular fields of vision are up to 50% wider.

Varilux X series represents Essilors greatest leap in near vision quality. For the first time, Varilux X series delivers wearers’ near vision depth. Patients can seamlessly capture every detail within arm’s reach, as well as beyond.

A pioneering approach to near vision

Near vision revolutionised

Wearers today need to multi-task quickly and freely. Varilux® X series™ lenses are designed with multiple fields of vision in mind. These near distance visual needs correspond to a range of between 40 and 70 cm from the wearer, known as arm’s length. Varilux X series has reinvented near vision at arm’s length.

Introducing Volume of Vision

Varifocal performance is measured by swim effect and binocular fields of vision. Varilux X series introduces a whole new performance criteria – Volume of Vision. When a wearer looks at a particular object through a Varilux X series lens they will now notice an improvement in depth and breadth of vision. This vision experience is exclusive to Varilux X series.

Reduced head movement

A common varifocal complaint from wearers is that they need to constantly move their head in the direction they wish to see. In all situations tested, Varilux X series wearers find they need very little head movement to find the right spot when multi-tasking at arm’s reach.

A new personalisation feature

Near vision tasks involves a whole body response, which is more complex than distance visions. For example, think of your body position when you read a tablet sat down. Varilux X series personalisation parameter ensures your patients’ vision volume is positioned and shaped where and how they need it.

The exclusive 4D technology takes the dominant eye into account in the lens calculations to ensure instant visual reaction for the wearer. All Varilux S Series are manufactured using S Digital Surfacing, which ensures a much more accurate blocking of the lens.

Whether you work in a digital environment, are a regular video game marathon enthusiast, or hooked on social media, Eyezen lenses may aid in preventing any potential damage due to daily exposure to harmful blue-violet light.

Blue protect lenses

There are many anti reflective coatings on the market at Barnabys we recommend Essilor Crizal prevencia, providing protection against harmful bluelight whilst still giving all the benefits of Essilors other leading anti reflection coating.  Prevencia lensesLatest research into AMD (Age related macular degenarartion-biggest cause of vision lost in the developed wordld) suggests the most damaging light reaching the back of the eye is not UV but VISIBLE violet light. This new technology enables lenses to block a significant proportion of this wavelength, reducing retianal cell death by around 25%.  (this is in addition to the EPS built into our S-Series varifocal lenses).

Crizal lenses

If your preference is for a traditional green anti reflection coating at Barnabys we recommend Essilor Crizal Forte UV, which is the first clear lens on the market to maximize protection against UV from the front AND back surface of the lens, while ensuring the maximum clarity of vision.

Other specialist lenses include amazing mirror finishes, occupational lenses, safety eyewear and many more tailored options are available at Barnabys. Simply call in for a personalised recommendation.

(1) Harmful light = UV and blue-violet light

(2) For Eye Protect SystemTM lenses with Crizal Forte® UV, 25% decrease in light-induced retinal cell death versus no filter. For standard lenses: Orma 1.5 or Airwear 1.59 with Crizal Forte® UV, about 7% decrease (mathematically modelled).The E-SPF® index depends on the lens material itself and the coating. E-SPF® is a global index rating the overall UV protection of a lens. E-SPF® was developed by Essilor International and endorsed by 3rd party experts. Lens performance only. The E-SPF® index excludes direct eye exposure that depends on external factors (wearer’s morphology, frame shape, position of wear).

(3) Based on In Vitro photoprotection tests on retinal cells. Smart Blue Filter™ lens feature provides a minimum level of efficacy, decreasing light-induced retinal cell death versus no filter: 25% (+/-5%). It depends on the lens material and the coating and can be evaluated by in vitro tests on RPE (Retinal Pigment Epithelium) cells or by mathematical modelling.
