Digital and Computer Lenses: Revolutionising Vision

There’s no doubt about it, the COVID pandemic has had a significant effect on eyes and vision. We hear it from researchers and behavioural optometrists, and we hear it from the myopia fraternity and the broader industry. Fortunately, today we have a growing body of spectacle and contact lens options tailored specifically to manage some of the eye and vision issues that have been aggravated by COVID.

The symptoms associated with COVID related vision issues are classic of asthenopia. However, due to the longevity of this pandemic and its consequential lockdowns, which drove people to spend long hours on digital devices, they are becoming more frequently reported and seem to be presenting at an ever-younger age.

Perhaps the only good news about this, as Andrea Rolando, Trade Marketing Manager at Essilor Australia explained, is that patient groups have become more aware of vision issues.

It’s easy to find the patients with poor amplitude, or accommodative weakness/facility who could benefit from anti-fatigue lenses

Ms Rolando said this has been evidenced by two strong trends emerging;

  • Anti-fatigue lens sales have grown against the sales of single vision lenses, and
  • The extended-focus category has consolidated its position against single vision lenses.

“Young people spending inordinate amounts of time on their mobile devices during lockdown quickly found out if their insufficient or weak accommodation was a problem,” she explained. “And optometrists were quick to recommend anti-fatigue lenses when these patients sought vision care for their symptoms.”

Many working from home experienced challenges with single vision, progressive, and bifocal wear that they hadn’t previously noticed. As described by Ulli Hentschel, National Training & Development Manager, Hoya Lens Australia, “COVID changed the way we work and live. With an increase in working from home likely to continue for many, spending most of our waking hours in front of a computer screen is becoming the norm. It’s time to start rethinking the way we prescribe lenses and stop talking about computer glasses as the ‘second pair’; they are the ‘primary pair’!”

Like others, Mr Hentschel noted the large growth opportunity for practitioners who focus on this category. “It’s another area where they can differentiate their offerings by suggesting more tailored solutions.”

Tim Thurn, Professional Services, Essilor ANZ, shared his views, based on extensive reading and 18 years of observations and experience since the launch of the original Essilor anti-fatigue lens in 2004.

“Accommodation needs to be more widely discussed – its function, or lack of, is a primary driver of optometry services worldwide. Presbyopes may be the bread and butter of the optical industry but, if we look closely enough, poor accommodation in young consumers is likely to be as big a market, and it remains virtually untouched. It’s easy to find the patients with poor amplitude, or accommodative weakness/facility who could benefit from anti-fatigue lenses.”

Mr Thurn shared a variety of sound research and provided a list of further reading resources, which he summed up with these important observations: “For practitioners, there’s a compelling story of a largely untapped market which would respond well to the use of anti-fatigue lenses. Simple binocular vision tests quickly highlight who will benefit from this type of correction. In times when every new patient counts, and competition increases, discussing visual fatigue and providing anti-fatigue lenses is an important point of difference that could pay enormous dividends for patient and practice.”

It’s important to remember that long periods of time spent performing near visual tasks can lead to accommodative fatigue; like any muscle there are limits to what the ciliary muscle can sustain. Research going back as far as 1937 noted that oscillations in accommodation occur. It has since been concluded that the ratio of high frequency oscillations (HFCs) to low frequency oscillations (LFCs), correlates with the level of visual fatigue. As accommodative micro-fluctuation LFCs increase, accommodation becomes more difficult, which can result in blurred vision.

Hoya, Essilor, Rodenstock, Zeiss, CR Surfacing, Shamir, and Independent Lens Specialists are among many suppliers that offer numerous lenses falling into the digital/anti-fatigue/computer category. Myopia control lenses can also potentially be included, as can specific selective filters (like blue blockers), which are touted as being beneficial to digital device users.

The boundaries between these lens categories are becoming blurred, but no matter how we define them, providing greater visual comfort, safety and performance, has to be a priority.

EVOLVING CONTACT LENS SOLUTIONS

The evolution in the management of digital eye strain and the prescribing of digital and anti-fatigue spectacle lenses has not been lost on contact lens companies.

CooperVision has specifically designed a contact lens to reduce eye tiredness associated with digital device usage. Shannon Morrow, Marketing Communications Manager for CooperVision, shared some insights on the Biofinity Energys design stating, “The lens has all the benefits of the proven Biofinity lens material but has been enhanced with a unique optical design, that’s ideal for both on-screen and off-screen activities.”

She added, “Innovation may have led to the dramatic increase in screen time, but innovation also holds the key to combatting its effects. Energys contact lenses are designed to help your patients’ eyes better adapt, so they can seamlessly shift focus between digital devices and offline activities for a more comfortable wearing experience.”

In this lens design, multiple frontsurface aspheric curves are employed across the entire optical zone. The even power distribution simulates more positive power in the centre of the lens to ease accommodative burden without impacting distance vision.

Multifocal contact lenses from other manufacturers can similarly be applied to lessen the accommodative demand on eyes in patients across a broad age range.

Crizal Lens Coatings

Essilor’s research and development team has launched a new range of Crizal lens coatings – Crizal Sapphire HR, Crizal Rock and Crizal EasyPro.

Made with ‘Life Proof ’ lens technology, this range has a cluster of new technologies around anti-reflection, scratch and thermal resistance, antismudge and UV protection benefits.

‘Life-Proof ’ comprises three key technologies:

  1. 360Åã multi-angular technology: reduces reflections from both the front and back surface of the lens, whatever the direction of the light, front-on, from the sides or behind the wearer. Lenses are virtually invisible.
  2. High resistance technology: an innovative coating formulation that combines four specific oxides with particular scratch and thermal resistance. One is used in the aerospace industry for heating shielding.
  3. High surface density process: a super hydrophobic, ultra-smooth top coat that blocks smudges with its highly effective ability to repel dirt and water.

According to Essilor, these new coatings extend the protection of up to 10 patents covering all Crizal coatings.

All have E-SPF 35 level UV protection against the invisible danger of UV. When combined with all lens materials (except clear CR39), 100% of transmitted UV is blocked and the coating’s special UV layer cuts UV rays reflected from the back lens surface.
