Photochromics, Sunglasses & Polarised Lenses

When it comes to sunglasses and outdoor spectacle lenses, there are many options for you to recommend. Take the time to understand the latest amazing technologies and explain the benefits to your patients. They’ll be delighted… as will you.

The global eyewear market is projected to reach AU$200 billion by 2020 with frames and sunglasses estimated to be around 40% of that total.

In America, over 80% of adults are said to wear sunglasses. Australians and New Zealanders, like Americans, spend a lot of time outdoors, making them ideal candidates for sunglasses as well.

As providers of eye care and vision correction we have a great opportunity, during the consultation or dispensing process, to discuss the importance of sunglasses with our patients. We should also educate them on the different options available that include Transitions, other photochromic lenses, regular sunglass and polarised lenses.

Be aware that competition is fierce in this space – if you don’t have the discussion, someone else will… but why let your patient walk out and obtain their sunglasses somewhere else, possibly even online.

PHOTOCHROMICS

Glass photochromic spectacle lenses were developed from technology invented by William H. Armistead and Stanley Donald Stookey of Corning Glass Works, USA in 1960. By the 70s and 80s, they had become popular in several markets.

The darkening that takes place in photochromic glass is based on silver particles that darken in a process akin to that which takes place in photographic film and paper. The major advantage of course, is that this reaction was reversible in glass spectacle lenses and the lenses cleared up when indoors or in low light.

Plastic photochromic lenses were developed in the 1990s. Rather than being silverbased, these lenses use naphthopyrans and other organic molecules that limit light transmission through a change in their molecular structure, triggered by UV light. Plastic photochromics are now the norm with glass lenses very rarely dispensed these days. While a number of major lens companies have their own proprietary photochromic lenses, the Transitions brand is synonymous with this category.

Transitions lenses have evolved through various generations, improving significantly over time. The current Transitions lenses use Chromea7 technology, which is more reactive for better lightening and darkening, more independent of temperature and more responsive to indirect light.

POLARISED OR NON-POLARISED?

Polaroid technology was developed by the legendary inventor Edwin Land in the 1930s. Again, with time, the quality and function of these lenses has improved dramatically and today there are even options with variable polarisation.

NuPolar, produced by Younger Optics is now the world’s leading provider of polarised prescription lenses, providing its technology to a number of other manufacturers.

One complaint we hear about polarised lenses is that they don’t darken enough in the car. There are several solutions to overcome this problem: XTRActive technology is one option, while Transitions Drivewear and Vantage options also include NuPolar polarisation.

There are still legacy instruments like fish finders and older phones that will blank out with polarised lenses. If patients are concerned, allow them to take a pair of demo polarised sunnies home to test out on all their toys. This will ensure they make a decision they are happy with.

PERSONAL EXPERIENCE

There are consumers who will tell you they don’t want photochromic or polarised lenses because they have endured bad experiences in the past. Now is the time to explain the technological improvements and offer satisfaction guarantees so they can try them again, risk-free. Most will be happy with what they discover.

I admit to being one spectacle wearer who had to be convinced. For many years I resisted progressive lenses – having tried many, they had all disappointed me and I could not tolerate them.

In late 2016, a colleague convinced me to give Zeiss DriveSafe Individual lenses a go. Like many patients, I prefer not to have to fiddle around, changing my glasses dozens of times a day when going in and outdoors, driving and so on, so I opted for Zeiss’ PhotoFusion brown photochromics. I haven’t looked back – I wear them all my waking hours, and they cover around 90% of my needs.

I had also been disappointed with various polarised lenses over the decades, having found the interference with screens on digital devices a problem. However, I recently upgraded my Rx sunnies to DriveSafe Individual progressives in a brown 85% tint with polarisation. Again, I am super happy with the results. My iPhoneX has OLED screen technology, which is ideal with polarised lenses, and so much better than the older legacy LCD screens. My laptop screen is also fine, and I have only noted mild dimming of my car’s multifunction dashboard display and radio screen. On extremely bright days, when I’m on the beach, in the snow, and occasionally when driving, I switch to my dedicated sunnies.

The lesson from this is that it pays to revisit technologies and to encourage those pedantic, difficult patients to do the same. You might be surprised, as will they. I’d also suggest you encourage your staff to try the various technologies available – when it comes to convincing doubtful patients, there’s nothing better than an enthusiastic recommendation from you or your staff.

SATISFACTION MULTIPLIERS

Whether your patient needs photochromic or polarised, Rx-able or plano sun lenses, there are many opportunities to meet their varying needs by providing multiple eyewear options. To do so, it’s a case of gaining an understanding of their lifestyle, hobbies and activities, which should be done while taking the case history and during consultation.

Farmers and gardeners, for instance, will often tell you they are very happy with photochromics for general use. Cyclists will express the need for specialised sun wear that can cover variable lighting conditions, as will golfers, skiers, fishers, drivers and more.

Some athletes will require frames and lenses that can be worn under helmets. Many will benefit from dedicated sunglasses with a wraparound frame. Wrap-compensated, steep base curve lens designs provide improved optical and cosmetic results. They also help prevent extraneous light from striking the cornea peripherally, which is then optically concentrated nasally, via the well documented peripheral light focussing (PLF) effect. PLF is linked to pterygium (surfers’ eye), cataracts and even to potentially cancerous skin lesions of the nose bridge.

The options to meet your patients’ needs are further expanded with a variety of lens colours, gradients, multicoats, mirror coatings, blue blockers, enhanced UV protection, variable polarisation and different grades of photochromics for different uses.

For active millennials, we now even have Transitions disposable soft contact lenses with UV protection, but that’s for another story…

In the meantime, spend time with your patients! Instead of simply providing one general pair of glasses, you might find them walking away with multiple options – that has to be a win-win for all concerned.

Most importantly, your patients will have maximum protection and function – for all their needs – rather than compromising their visual comfort with just one pair of spectacles.
