Lenses: Living in a digital world

Optician presents a selection of lenses designed to combat the symptoms of digital eye strain

Hoya: Sync III 

Sync III from Hoya is designed to support the eyes in a digital world. Sync III is an enhanced single vision lens with distance power for everyday use and a choice of three ‘boost zones’, optimised for the way patients use digital devices. 

The boost zone within the lower part of the lens, provides slightly increased lens power, which is said to help to relax the eye muscles so that they focus more easily, relieving eye strain and enhancing visual comfort during up-close activities.  

Sync III can be paired with Hi-Vision LongLife BlueControl, a coating said to reduces the blue light emitted by digital screens which may help to reduce eye fatigue and eye strain.  

Hoya also says the lens can be further enhanced with the Sync IIIi design, which incorporates the patient’s individual facial and frame parameters.  


Norville: Evrifocal 

Norville’s Evrifocal is a free-form multifocal lens designed to help wearers comfortably navigate the digital world.  

The company says Evrifocal is not a bifocal, trifocal or progressive, but is a natural accommodation lens that delivers multifocal performance with a single vision viewing experience. According to Norville, the difference between a regular progressive addition lens (PAL) and an Evrifocal lens is in the design. 

PAL lenses have an hourglass shape with a wide distance field, a narrow intermediate, and a wider near portion. Norville notes that a common side effect of PAL lenses is blurry peripheral vision.The Evrifocal lens design has a wide funnel shape at the top, and goes from distance, gradually decreasing to near at the bottom of the frame.  

Since the intermediate and near zones are wider than a PAL, the eye is said to move effortlessly through these zones, thus eliminating the distorted peripheral that plague PAL designs.  

Norville also says Evrifocal benefits from no peripheral swim effect, no fitting height required, and provides clear natural vision in all distances. 


Caledonian Optical: The Office 2.0 

Caledonian Optical notes that remote working and reliance on screens becoming more common than ever before, and that its The Office 2.0 lens is well-placed to support patients’ vision in this context.  

Office 2.0 lenses are said to be well suited for those working indoors who frequently use electronic devices. These lenses are recommended for people who spend extended periods of time viewing objects in near and intermediate distances, remote workers who frequently use screens and older people whose eyes may need additional support. 


Rodenstock: Ergo 

Whether working in the office or at home, Rodenstock says Ergo lenses relieve the strain on eyes and posture, leaving patients with more energy at the end of the workday.  

Benefits of these near vision lenses are said to include superior vision at work thanks to custom lenses, a more relaxed head and body position due to optimal fields of view, a scratch-resistant, easy-maintenance coating for long-lasting lens enjoyment, and an optional innovative coating that filters blue light for a balanced biorhythm. 

Rodenstock says that, at work, eyes must constantly adjust to different distances and near vision work often leads to dry eyes, headaches or strained neck and shoulder muscles. The company says Ergo, as an individual near vision lenses based on a complete biometric model of the eyes, offers a solution to this.  

The company describes its Solitaire Protect Balance 2 coating as the perfect companion for near vision lenses because it is said to reduce blue light transmission emitted from digital devices.  


Essilor: Eyezen Start  

Eyezen Start single vision lenses from Essilor are designed to support modern lifestyles by relaxing and protecting your eyes.  

The lens is designed for under-40s but is said to be suitable for single-vision users of any age who are switching between devices, adopting new postures, and adjusting to close and variable distances.  

The company says its Revolutionary Dualoptim and Dualoptim S technology optimises the whole lens surface for distance and near vision to bring the right power through the lens based on location of objects and gaze direction. Meanwhile, the BlueUV Filter System protects eyes by absorbing UV and filtering blue-violet light into the material of the lens. 

Alan Pitcher, commercial director for wholesale lenses  at Essilor UK, said: ‘Patients are spending a lot of time looking at screens and Eyezen Start is a dedicated lens that ECPs can recommend for reducing eye strain and helping patients see more comfortably.’  


Eye Index: HD Lifestyle Occupational Lens  

Specialist UK prescription house, Eye Index, says it has always had a strong focus on occupational eyewear and notes that the digital world we now live and work in calls for the best ophthalmic technology to enhance vision and reduce eye strain. 

The HD Lifestyle Occupational Lens, with smart add technology and digital surfacing, is said to improve the patient’s visual and postural experience when using a range of digital devices, especially with multi-screen operations.  

It offers four working distance options and is said to help manage eye fatigue and reduce the risk of headaches caused by over-exposure to screen work. Eye Index says the lens offers maximum customisation for patients, reduces oblique aberrations and expands visual range.
