Crystal Clear Premium Lens Coatings

Multicoated spectacle lenses improve the vision experience of wearers yet many eye care professionals ignore or forget to take the opportunity to explain the options to their patients. The advantages of doing so are numerous for both patient and practice.

In previous issues of mivision we’ve looked into the optics and function of multi-layer anti-reflection coatings, better known as multicoated spectacle lenses. There’s no doubt that multicoated lenses provide the benefits of much better cosmesis, improved light transmission, and better vision in varying light conditions. Multicoated lenses usually include a UV blocking layer as well as a hard coat (that renders the lens more scratch resistant than an uncoated lens.)

Premium coatings also usually include easy clean, anti-greasing, and deposit resistant properties, and may include optional ‘digital’ and selective blue blocking layers that block high energy visible light.


Although many of us have been prescribing multicoated lenses as a routine for decades, it seems there are still some practitioners and dispensers who do not offer or prescribe such benefits. One just has to look around at spectacle wearers to see how many wear unsightly, regular lenses, with significant reflections. Some of these wearers may have obtained basic, uncoated lenses on a ‘special deal’ from the chains, or elsewhere, and resisted the extra cost when offered ‘add-on’ options like multicoats.

It also appears that some practitioners simply can’t be bothered offering multicoat options, while others are price sensitive and are wary of trying to compete with the chains. Either way, they are making a mistake.


As many marketing experts will tell you, we should never judge our patients or make decisions on what we think they can afford or may spend. The badly dressed or unkempt person in your chair could well be a billionaire wanting the very best in eye wear and a high level of visual performance. Even those who are less wellheeled and on tight budgets will often be swayed into value additions like multicoats, provided we explain and demonstrate the benefits. In my experience, some cultures will club together and pool their money so that each month one of them can afford more costly items that they otherwise would not be able to fund.

Although some lens manufacturers offer add on multicoats at unjustifiably high prices, most spectacle lens manufacturers provide many of their lenses ‘off the shelf ’ as stock lenses that already include a multicoat, often for only a few dollars more than a non-coated lens. We can pass this value added benefit on to the patient. Even with a small mark up, it will not make much difference to the final price, thus eliminating ‘cost factors’ from the decision.


For prescriptions that are custom generated, most manufacturers have state of the art coating plants in Australia and New Zealand, or in a matter of days, can obtain multicoated lenses from their laboratories in Europe, Asia, and elsewhere.

However, some labs may not have the meticulous cleaning systems and clean rooms required to obtain top quality coatings that last, leading to premature coating failure. Even the major manufacturers do occasionally have lenses or batches of lenses that undergo coating failure. A few years ago a certain globally respected manufacturer had a series of 1.6 index lenses in which they discovered (in retrospect) that the expansion characteristics of their hard coat, UV coat, and anti-reflection coatings, did not match, causing rapid crazing and peeling of the coatings. Of course most issues were resolved under warranty.

We should treat all our patients as a ‘patient for life’. If you add up what the average patient will spend with you over a lifetime, it is certainly not insignificant

Apart from non-adaption to progressives, nothing irritates a patient more than unsightly lenses caused by coating failure. Some of these spectacle wearers may have damaged or scratched the surfaces through improper care – they may have tried to dry clean dusty lenses with their T-shirt or other cloths and towels. An important step during the dispensing process is to demonstrate proper cleaning of multicoated lenses and provide patients with a cleaning kit comprised of specialised spray cleaner and a microfiber cloth in a small pack. These spray bottles and cloths should ideally be branded with the practice logo and contact details, as should the spectacle case. This will keep your brand front of mind for the wearer and promote your practice to potential new patients. All you need is for someone to admire the crystal clear, reflection free, thin, hi-index lenses in a well-fitted, stylish rimless frame; compare them to their own unsightly lenses and cheap alloy frames… then ask where the amazing glasses came from…


To avoid the hassles of unhappy patients, in the rare event that their lenses suffer coating failure, most manufacturers offer at least a one year guarantee on their coatings while savvy practitioners may offer a two year guarantee, either negotiated with the lab or covering relevant issues themselves. It’s better to keep your patients happy than to lose them to a competitor forever. We should treat all our patients as a ‘patient for life’. If you add up what the average patient will spend with you over a lifetime, it is certainly not insignificant.

Today we should also consider offering so called ‘digital coatings’ and somewhat controversial ‘blue blocking’ lenses, both of which have been written about in past mivision issues. These coatings appeal to many users of computers and digital devices, like smartphones and tablets, as well as people who spend time under LED lights. The blue light emitted by these digital devices and lights may reduce asthenopia and minimise disruption of sleep cycles, and also potentially reduce retinal damage. The jury is still out on the benefits of blue light filters, but if they do no harm while offering potential health benefits, then why wouldn’t we also prescribe this add-on for the majority of our patients?

Check out what’s on offer from our featured suppliers, or contact your lens rep. I’m sure you’ll be surprised at some of the competitively priced options out there, and hopefully you’ll convert more patients to the benefits of multicoated lenses, simply by articulating the offer.

It’s a competitive world out there.

Every little thing adds up.
