ZEISS SmartLife Young Lenses

Children constantly grow and change, and so do their visual needs. Their vision is influenced by the way they use digital devices.

SmartLife Young lenses are specifically designed to consider the age, anatomy, lifestyle and visual needs of growing children from 6-19 years in a digitally-immersive world. It also gives best optical performance for hyperopic and myopic children.

Lined Bifocal/Trifocals

Lined bifocals allow for a fuller range of vision with set visibly defined sections dedicated to distance, intermediate and near focal points.

Progressive Lenses

Progressive lenses have a smooth transition between parts with different focal lengths, correcting for vision at all distances without the disruption of a defined line.

ZEISS SmartLife Young Lenses

Your go-to lens portfolio for a digitally-immersive world. Designed for frequent changes of head and eye position, driven by the way in which people interact with their handheld devices while on the move. The lenses enable peripheral vision in natural dynamic interaction which allows smooth vision from near to far across all viewing zones.


Occupational Lenses

Occupational progressive lenses are designed specifically for prolonged visual tasks, like working inside an office, to help alleviate eyestrain and even reduce fatigue. Occupational lenses maximize your visual range and focus at arm's length distances, providing a clearer viewing zone up to 5 times larger than conventional eyeglass lenses. And they are available with an array of lens treatment to eliminate glare and reflections from office lights and computer screens.

Zeiss Office Lens

At the beginning of the day, people who work at a computer and wear single vision or progressive lenses may see well. However, as the day progresses, this may change. Eyes may begin to feel tired or dry and vision may become blurry. This can lead to more blinking. Some wearers may even experience headaches around or behind their eyes. All these symptoms are typical of eye strain and may require specific office glasses.


ZEISS Officelens will give you crisp, clear vision and are available in the three working distances:

  • ZEISS Officelens Book: Widest fields of clear vision out to 3 feet (100cm).

  • ZEISS Officelens Desk: Wide fields of view out to 7 feet (200cm).

  • ZEISS Officelens Room: For indoor or closer-range outdoor activities out to 14 feet (400cm).


Wearing Officelens glasses results in a more natural head and neck posture, providing complete comfort all day long


Eyeglass Lens Materials – Features And Benefits

Glass

In the early days of vision correction, all eyeglass lenses were made of glass. Although glass lenses offer exceptional optics, they are heavy and can break easily, potentially causing serious harm to the eye or even loss of an eye. For these reasons, glass lenses are no longer widely used for eyeglasses.

Plastic

In 1947, the Armorlite Lens Company in California introduced the first lightweight plastic eyeglass lenses. The lenses were made of a plastic polymer called CR-39, an abbreviation for "Columbia Resin 39," because it was the 39th formulation of a thermal-cured plastic developed by PPG Industries in the early 1940s. Because of its light weight (about half the weight of glass), low cost and excellent optical qualities, CR-39 plastic remains a popular material for eyeglass lenses even today.

Polycarbonate

In the early 1970s, Gentex Corporation introduced the first polycarbonate lenses for safety glasses. Later that decade and in the 1980s, polycarbonate lenses became increasing popular and remain so today. Originally developed for helmet visors for the Air Force, for "bulletproof glass" for banks and other safety applications, polycarbonate is lighter and significantly more impact-resistant than CR-39 plastic, making it a preferred material for children's eyewear, safety glasses and sports eyewear.

Trivex

A newer lightweight eyeglass lens material with similar impact-resistant properties as polycarbonate is called Trivex (PPG Industries), which was introduced for eyewear in 2001. A potential visual advantage of Trivex is its higher Abbe value (see below).

High-Index Plastic

In the past 20 years, in response to the demand for thinner, lighter eyeglasses, a number of lens manufacturers have introduced high-index plastic lenses. These lenses are thinner and lighter than CR-39 plastic lenses because they have a higher index of refraction (see below) and may also have a lower specific gravity.

Eyeglass Lens Treatments

Anti-Scratch Coating

All lightweight eyeglass lens materials have surfaces that are significantly softer and more prone to scratches and abrasions than glass lenses. The softest eyeglass lens is also the one that is the most impact-resistant: polycarbonate. But all plastic and high-index plastic lenses require a factory-applied anti-scratch coating for adequate lens durability.

Most of today's modern anti-scratch coatings (also called scratch coats or hard coats) can make your eyeglass lenses nearly as scratch-resistant as glass. But if you're hard on your glasses or you're buying eyeglasses for your kids, ask about lenses that include a warranty against scratches for a specific period of time.


Anti-Reflective Coating

An anti-reflective (AR) coating makes all eyeglass lenses better. AR coatings eliminate reflections in lenses that reduce contrast and clarity, especially at night. They also make your lenses nearly invisible, so you can make better eye contact and you and others aren't distracted by reflections in your lenses. AR-coated lenses are also much less likely to have glare spots in photographs.

Anti-reflective coating is especially important if you choose high-index lenses, because the higher the refractive index of lens material, the lighter the lenses reflect. In fact, high-index lenses can reflect up to 50 percent more light than CR-39 lenses, causing significantly more glare, unless AR coating is applied.

Anti-reflective vs. blue light coatings: What is the difference?

Research has shown that people of all ages are spending more time on digital devices. Besides facing potentially harmful blue light emitted by the sun, people also spend more time indoors where buildings are nowadays equipped with blue light-emitting LEDs. This can cause digital eye strain and affect sleep.

Zeiss BlueGuard Lenses are innovative blue light blocking lenses that guard against potentially harmful blue light and provide sunglass-level UV protection. These are particularly suitable for people who spend a lot of time working on computers or who are constantly on their digital devices.

UV-Blocking Treatment

Cumulative exposure to the sun's harmful ultraviolet (UV) radiation over a person's lifetime has been associated with age-related eye problems including cataracts and macular degeneration.

For this reason, people should protect their eyes from UV beginning in early childhood. Thankfully, polycarbonate and nearly all high-index plastic lenses have 100 percent UV protection built-in, due to absorptive characteristics of the lens material.

But if you choose CR-39 plastic lenses, be aware that these lenses need an added coating applied to provide equal UV protection afforded by other lens materials.

ZEISS DuraVision BlueProtect UV

Natural light, i.e., sunlight, contains many types of colored light. One of the shades of light in the visible spectrum is blue light. It accounts for about one third of high-energy visible light (HEV). Blue light ranges from 390 to 500 nm on the visible light spectrum, which penetrates the eyes easily, passing through the cornea and lens to the retina. Blue light filter solutions such as blue light lens coatings for eyeglasses are a suitable solution to this problem. By wearing appropriate lenses with a blue light coating, a reduced amount of blue-violet light can enter the eye.

DuraVision® BlueProtect UV is a blue light lens coating specifically developed for patients who spend a lot of their time indoors and are exposed to blue-violet light from LEDs as well as TV, computer or tablet screens.

Zeiss DriveSafe Lenses

Glare reflected off of transparent or wet surfaces is not only annoying and distracting – it can also affect vision and can be distracting. No matter how far the distance, good vision is vital for safety as well as comfort. However, driving in certain conditions can be challenging to anyone, especially when wearing glasses. Zeiss DriveSafe lenses help you see every detail on the road. Design features and key technology enhance the wearer’s vision experience during the day or night while driving. Thanks to the DuraVision DriveSafe Coating, reflections are reduced as well as irritating glare, especially while driving at night.
