Reacts from dark to clear in seconds
Trivex® for Kids  Ideally children's lenses should be made of polycarbonate or a material called Trivex®. These lightweight materials are significantly more impact-resistant than other lenses. In addition to being the safest materials, they also are lighter in weight than regular plastic lenses.

Polycarbonate and Trivex® have built-in protection against potentially damaging ultraviolet (UV) rays and the lenses are scratch-resistant coated.

What is i.Scription®?

i.Scription® technology by Carl Zeiss Vision is based on their eye measuring system called the i.Profiler® abberometer designed to determine the exact “fingerprint” of your eyes and provide detailed information about your unique needs.
1500 me
asuring points are used to determine an exact visual profile of your eye. Even the slightest deviation from the ideal shape of the eye is measured electronically. Based on your personal visual profile, Carl Zeiss Vision computes a precision lens designed to match your eye perfectly. No other manufacturers’ spectacle lenses are produced with this level of precision.

Better night/low-light vision

Looking directly at a light source at night results in glare and halo effects, e.g. car lights. These are reduced by i.Scription® technology.

Better visual

Seeing contrast e.g. white letters on black background is especially challenging of the eyes. iScription® technology sharpens contrast.

Better colour vision

i.Scription® technology adds more brilliance to your life and lets you see colours as they really are: bright and more intense.

Wavefront lenses

Measurements from your eye examination and the iProfiler® aberrometer are sent to Carl Zeiss Vision who manufacture your personalised  iScription® high definition spectacle lenses that reduce high level aberrations which restrict field of view and cause starbursts and distortions of lights at night.

Computer lenses

Due to the awkward distance a computer display screen and keyboard can be from the eyes, often normal reading or distance spectacles are unsuitable for prolonged periods of VDU work. Nowadays there are dedicated designs of varifocal lenses which allow you to focus on your display screen, keyboard and desk with a much wider field of view than a normal varifocal. These ‘Business’ lenses are invaluable to busy VDU operators.

Trivex® and polycarbonate safety lenses

When eye safety is a concern, polycarbonate or Trivex® lenses are usually the best choice for your spectacles, sunglasses and sports eyewear.

Both polycarbonate and Trivex® are thinner and lighter than regular plastic lenses. They also offer 100 percent protection from the sun's harmful UV light and are up to 10 times more impact-resistant than plastic or glass lenses.

This combination of lightweight comfort, UV protection and impact resistance also makes these lenses an excellent choice for children's glasses and safety glasses.

They also make a very good choice for rimless frames where the lenses are attached to the frame components with drill mountings.

Photochromic lenses

Photochromic lenses such as those made by Transitions Optical® or Carl Zeiss Vision® are clear (or nearly clear) indoors and darken automatically in response to sunlight outdoors. They also protect your eyes from 100 percent of the sun's harmful ultraviolet radiation.

These features make photochromic lenses a great convenience, because they reduce your need to wear prescription sunglasses in most outdoor conditions.

Today's photochromic lenses come in a wide variety of lens types. So, whether you prefer high-index lenses, or regular plastic or glass lenses, you will be able to purchase a photochromic version of your preferred lenses.

The new PhotoFusion® photochromic lenses from Carl Zeiss Vision® react up to 20% faster than existing Carl Zeiss Vision lenses and are available in all their lens design ranges.

Tints for sport

Most lens manufacturers offer a range of tints or filters for use by sportsmen and women. However the choice of colour and density should be carefully considered when choosing as it is dependant not just on the sport but also the subjective preference of the wearer.

There are 4 main types of tint:-

Fixed tints (Full or Graduated)

The commonest used tints are grey, brown and green. Depending on the colour, these filters reduce the intensity of light entering the eye with or without enhancing the contrast of objects. There is a minimal distortion of colours with these tints.

The com
monest uses for these tints are; Driving, golf, tennis, mountaineering, running and skiing.

If high contrast is required then orange and yellow filters are highly effective. These lenses do distort colour so are not suitable for activities which require accurate colour recognition. They work well on overcast, hazy or foggy days and enhance depth perception.

The commonest uses for these tints are: Driving, shooting, golf, skiing (in low light levels), cycling, flying and sailing.

Photochromic tints

Due to the density of the tint being able to vary according to the level of sunlight photochromic filters are ideal for activities taking place in variable light/weather conditions.

Polarised tints

These filters eliminate blinding glare from reflected light bouncing off surfaces like water, concrete or wets roads. They are good choice for fishing, water sports, driving and cycling. However they are not a good idea for sports such as skiing when the skier relies on reflections to see ice.

Mirror tints

These filters reduce glare and infrared light. They are ideal for water and snow sports. Often the mirror tint is combined with a fixed tint to improve its performance.


Drivewear® is the first polarised photochromic lens to darken behind the windscreen of a car, which allows Drivewear® lenses to change colour based on current driving conditions in order to enhance the driver’s vision and provide protection from blinding glare.

Due to its polarisation and photochromic properties the Drivewear® lens is excellent for many sports including fishing, shooting, cycling, tennis, golf and sailing.

Drivewear® lenses are available in plano and prescription form and in single vision and varifocal designs.

The new self-tinting lenses by Carl Zeiss Vision react up to 20% faster than existing Zeiss photochromic lenses.
