Part 11: Did you know …

... that our eyes are not made for today's world?

The "lensed eye" evolved millions of years ago and continues to provide vertebrates – including human beings – with their sense of sight. It is the most powerful visual organ that evolution has ever produced. However, we are now beginning to realise that it may not be capable of meeting all the visual challenges that we face in the modern world.

1. Vision in the digital age

Vision in the digital age

Our lives increasingly revolve around digital devices such as smartphones and tablet computers. On average, we spend 4.5 hours a day using these devices, typically looking at a digital display between 60 and 80 times a day.*

Few people realise how hard this makes our eyes work. Firstly, it requires us to frequently refocus our vision. That puts a strain on our eyes and leads to fatigue, headaches and neck pain.

But it also involves a second key element: we are using our close-up vision more than we used to, and generally in a highly focused way. Opticians have also observed that more and more people are becoming short-sighted at an earlier point in their lives. This is even evident among children. In our modern, digital world we spend too little time looking into the distance and letting our eyes relax.

This new kind of close-up vision also involves viewing things at a different distance to that used in "traditional" reading. When we read text on a smartphone, we tend to hold the device significantly closer to our eyes than a book or a newspaper.

Modern spectacle lenses, particularly progressive lenses, have to take these fast-evolving trends into account. Progressive lenses support our vision at both near and far as well as in the middle distance or intermediate range. The lens design is critical, and determines where the different vision zones are positioned on the lens, and what proportion of the lens each zone occupies. Achieving relaxed vision when using digital devices, for example, requires an enlarged reading zone.

2. Better vision that matches your personal style

Better vision that matches your personal style

Fashion is changing faster than ever – and not just in terms of clothing. In tandem with the makers of fashion accessories, shoes, bags and jewellery, spectacle frame manufacturers are also offering an increasingly wide range of attractive, innovative frames which offer the perfect match for your personal sense of style.

It's fun to switch from large frames to smaller ones, and it's just as much fun to switch back again!

But one thing that should remain constant at all times is the quality and comfort of your vision – and that's particularly true of progressive lenses. Whatever frame you wear, you should ideally be able to look through your usual visual zones in the same relaxed way as always. That may sound like wishful thinking, but ZEISS has turned it into reality by taking into account each wearer's personal visual behaviour.

3. Better vision in traffic

Better vision in traffic

Driving has come to mean many different things – from fun and independence to a necessary evil, depending on your perspective. Unfortunately studies have shown that many drivers feel stressed, tense and nervous at the wheel. This could be due to the huge increases in traffic volumes, or simply because people are driving faster. Drivers become particularly edgy and unpredictable when visibility is hindered by rain, fog, or snow, as well as at night and in the low light of dawn or dusk. If visibility is poor, we become tired more quickly and react more slowly. So what do drivers really need to provide them with good vision on today's roads? Modern lenses should take every aspect of driving into account while retaining their full range of benefits for everyday use:

  1. Lenses for driving should provide optimum vision in bad weather, at dawn or dusk, and at night.
  2. Lenses for driving should be designed to minimise vision problems caused by glare.
  3. Lenses, particularly progressive lenses, should be designed to cater to rapid and frequent refocusing from near to far and vice versa.
