What sunglasses are right for your favourite activity?

There's a perfect pair of sunglasses for any occasion. A good pair of sunglasses isn't just a stylish accessory – it also helps provide optimum vision in bright sunlight and protects your eyes from harmful UV radiation.

Protection, style and convenience all year long

A good pair of sunglasses means you'll only enjoy the sunny side of life. However, this requires sunglass lenses that accommodate your needs and daily routines. Keep in mind that the better the fit to the individual wearer, the more comfortable the sunglasses are to wear. So if your eyes are sensitive to bright light, then you should choose a somewhat darker tint. Bright and gradient tints are ideal on cloudy days with little sunlight, whereas dark tints protect your eyes in strong sunshine.

Which sunglasses are right for which situation?

Basically, we differentiate between three main situations where you need sunglasses: for the city, driving, and sports. There is an optimum tint intensity for any given situation so that your sunglasses are neither to dark nor to bright. You can choose from tint levels ranging from 0 to 97 percent light absorption – in line with the light intensity and when you'll be wearing your sunglasses.

Sunglasses for strolling through town or when indoors (very low light intensity)

The perfect companion when shopping - and a stylish accessory while indoors: for cloudy days out and about in the city or when inside, sunglasses lenses with a light absorption of 0 to 20 percent are optimally suited for the urban environment.

Sunglasses for days with only minimum sunshine (low light intensity)

The sky might be cloudy, but every now and again the sun peeks through: on those days with a but of sunshine, sunglasses lenses with mid-range light absorption of 20 to 60 percent are perfect for spending time in the city.

Sunglasses for on the beach and in the water (mid-range light intensity)

When spending time on the water and at the beach with mid-range light intensity,we suggest you get sunglasses lenses with 57 to 82 percent light absorption. Perfect for blue skies and bright sunshine weather condition.

Sunglasses for cyclists (mid-range light intensity)

The best option for cyclists is ZEISS sunglass lenses with light absorption between 57 and 82, a somewhat brighter tint. Amber and rose for eg, have proved ideal when biking and in little to no sunlight: these bright, high contrast tints enable the eye to quickly and clearly identify tiny details - even in limited light.

Sunglasses for golfers ( mid -range light intensity)

A good pair of sunglasses for golfers should not only darken, but improve contrast perception at the same time. In particular light to dark purple or yellow orange tints increase contrast on green surfaces, optimizing contrast perception and enhancing contours on the fairway. Sunglasses lenses with light absorpbtion of 40 percent or 75 and 25 percent(gradient) are well-suited for golfers.

Sunglasses for driving ( mid-range to high light intensity)

For optimum vision when sitting behind the wheel, your sunglasses lenses must have a polarization filter to reduce distracting glare(caused by sunlight or reflections on the wet road) along with a tint suitable for driving. It is recommended that drivers get sunglasses lenses or regular spectacles lenses with 57 to 92 percent light absorption.

Sunglasses for water sports ( mid range to high light intensity)

Being on the water poses several different challengers to our eyes. The surface of the water reflects the sunlight, often resulting in irritating glare and reflections. Water sports aficionados like surfers and sailing enthusiast benefit from sunglasses lenses with an integrated popularization filter and a mirror coating. This minimizes irritating glare and ensures unimpeded vision. When it comes to tints for spending time on the water: generally, light absorption between 57 and 92 percent is ideal.

Sunglasses for up in the mountains ( extreme light intensity)

Whether you're hitting the slopes, climbing or mountaineering, having a good pair of sunglasses is an absolute must! At high elevations such as up in the mountains, we need to protect our eyes from damage caused by UV radiation as harmful levels of UV light are generally present even if the sky is cloudy or foggy. In extreme light conditions, such as on a glacier at extremely high altitudes, sunglasses with light absorption of 80 to 95 present and a very dark tint are the way to go. Wrapped lenses and frames are also recommended to prevent light entering from the side.

Tips for Sunglass Wearers

• Make sure that the sunglasses lenses are 100% UV protection to prevent harmful UVA and UVB radiation from damaging your eyes -  a must-have for every pair of sunglasses. Not all sunglasses in the market come with 100% UV protection.
• Taking good care of your sunglasses lenses is important. During purchase, make sure you select the right lens coating so you can enjoy your sunglasses for a long time. Make sure your lenses have a hard coating to protect them against scratches along with an anti-reflective coating to keep irritating reflections in the lens to a minimum.
  
• There is an optimum pair of sunglasses for every activity, whether indoors, on the golf course or up in the mountains. If you're unsure which tint intensity or colour is best for you, talk with your optician.
