The latest technology for single vision lenses

Share on

It’s fair to say that our lifestyles are evolving at a very fast rate. It was only less than 40 years ago that the internet was invented and since then our lives have become busier than ever before. The world we live in now is home to digital devices that have changed the way we work and socialise, new light sources that are used for more than just lighting the way and new research that can help us live longer and more comfortably. The design of a single vision lens has changed very little since it's invention in the 1800s, meaning our corrective single vision lenses are not answering our lifestyle needs of today.

The impact of a modern lifestyle

Our modern lifestyles have triggered physiological and behavioural changes that older spectacle lens technology is not able to keep up with. For instance, reading distances and eye declination are different when we look at a tablet or smartphone, compared to when we read a book.

Without wearing lenses that are optimised for such a change in lifestyle, we may experience the likes of visual fatigue and discomfort.

We are an ageing population, which is associated with an increased risk of eye diseases like cataracts and AMD.(1)

Research has shown that exposure to harmful light, such as UV light and Blue-Violet light, can have a negative impact on our eyesight.(2)

Wearing single vision lenses

It’s important to see a local optician regularly for an eye examination. It is recommended that you have an eye examination every 2 years, or sooner if something has changed in your vision. This can be a helpful step in identifying any problems early, giving you more chance of corrective treatment.

Many of us suffer from refractive errors such as myopia and hypermetropia; it is thought 1 in 3 people have myopia. After an eye examination the optician will discuss the need for lenses to correct the refractive error.

Together with increased use of digital screens on a regular basis, there is a chance many of us will experience tired eyes and an overall uncomfortable visual experience. Our modern lives now mean we often switch between variable distances and look at pixelated characters, which means our eyes need to work harder.

If you need to wear single vision lenses to correct your vision, it’s in your best interest to find the right lenses to suit your lifestyle.

Eyezen technology

Previous single vision lens designs would require you to look through the centre of the lens to see clearly, resulting in neck and shoulder pain as you have to move your head downwards to see close distance objects, like your smartphone.

Eyezen lenses are single vision lenses that are optimised throughout the whole lens, maintaining the high optical standards that we expect, so you can look through the bottom part of your lens to see close up objects  instead of having to lower your head and neck to see clearly. Eyezen single vision lenses are enhanced to prevent and reduce eyestrain providing you with a more comfortable vision experience no matter what your busy lifestyle throws at you. Delivering sharper vision and reducing visual fatigue, you can get on with your routine easier than ever before. Even if you don’t need a prescription, you can still take advantage of this technology.

Additional protection for your eyes

It’s becoming increasingly more important to find ways to protect ourselves from the evolving world we live in. Research shows that harmful light is emitted from light sources, including the sun primarily, followed by LED lighting. It’s important to protect our eyes from this.(3)

Eye Protect System is a revolutionary technology embedded into the lens. It works on the front and back of the lens to provide optimal protection. It partially filters Blue-Violet light and absorbs UV light, while maintaining an aesthetically clear lens with no yellow tint or blue reflections.(4)

Reducing glare and reflections

We shouldn’t have to deal with distracting reflections and harsh glare in 2019, but it can be quite common when wearing spectacle lenses. Crizal has been developed to further enhance your lenses, making it even easier and more comfortable to wear them.

Crizal Sapphire UV delivers optimal transparency, fewer reflections, as well as repelling from water, dust and smudges to keep your lens clean and clear. It even provides a scratch resistance surface for the lens. Crizal Prevencia offers similar benefits, as well as further protection from and Blue-Violet light.

Our modern lifestyles deserve modern solutions

For Eye Protect SystemTM lenses with Crizal Sapphire® UV, 25% decrease in light-induced retinal cell death versus no filter. For standard lenses: Orma 1.5 or Airwear 1.59 with Crizal Sapphire® UV, about 7% decrease (mathematically modeled). 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 cells or by mathematical modeling.
