Bifocal & Progressive Lenses

Both bifocal and progressive (varifocal) lenses allow for prescriptions for distance and reading to be used in a single lens. While bifocals offer a reading segment (normally in a 'D' shape), progressives include the benefit of a no line lens offering a seamless progression from reading, to intermediate to distance, making them perfect for all day wear.


Distance, intermediate and near vision correction in a single pair of glasses.


Traditional varifocal

While lens technology has progressed over the years, traditional (or conventional) progressive lenses offer 3 blended prescriptions correcting near, distance and inbetween vision, that's relatively easy to adapt to for new wearers.

However, as this is an older technology you'll find these lenses have medium levels of peripheral distortion and this may result in difficulty with adaptation when compared with a freeform progressive design.

As such, and due to negative points surrounding the traditional design, we no longer offer this lens. Instead, all our progressive lenses now offer superior freeform technology.


Rear surface, freeform varifocal

Using the latest in lens manufacturing technology, rear surface freeform lenses are digitally optimised for you and your prescription and choice of frame. This results in a greater field of clear vision (up to 50% greater than traditional varifocals) with minimal soft focus and peripheral distortion. Another added benefit is that these lenses are very easy to adapt to.


Adapting to progressives

When you're trying progressive lenses for the first time or perhaps have an updated prescription, you may need a short period of time to feel fully comfortable with the lenses. This adaptation period can vary from just a few minutes, a few days, or up to 1 month. For quicker adaptation, we recommend choosing a rear surface freeform progressive lens.

To speed up the adaptation period, we recommend wearing your new glasses around the house or office initially trying not to return to your old prescripiton glasses. For driving, it's recommended that you only use your new progressive lenses once you feel completely comfortable with them.

Our progressive lenses

We offer 3 progressive options, all with freeform technology.


Standard Varifocal

IOT Basic series H40 Design Freeform Progressive Lens

Our standard design is ideal for new and familiar progressive lens wearers, offering wide distance and near zones for natural eye movements, coupled with a smooth progression to near vision. Compromise between far and near vision has been efficiently balanced to provide the wearer with a comfortable all-purpose lens.

This hard lens design is ideal for general purpose where there is no intention for prolonged intermediate use.


Premium Varifocal

Optimize Acuform Design Freeform Progressive Lens

Our premium design provides tremendous clarity from distance through to near offering up to 20 percent wider corridors of vision with minimal soft focus and incredibly fast adaption. Produced with the latest Digital-Surfacing technology and software to effectively balance the visual field and provide wearers with a stable and generous focal area for distance, intermediate and near tasks.

This soft lens design is ideal for wearers that spend a lot of time with intermediate and near tasks.


Elite Varifocal

IOT Alpha series H45 Design Freeform Progressive Lens

Our elite design offers optimised Digital-Ray-Path technology with balanced power distribution between distance and near vision areas for enhanced vision across the whole lens including intermediate working distances.

This hard lens design is highly recommended for experienced and demanding wearers that are looking for an all-purpose progressive lens, generous at all distances with comfortable all day vision.

Liberty 3.0

Uniform sharp vision when looking in the distance through to objects up close. Varilux Liberty 3.0 lenses deliver a reliable vision all around.  

  • Smooth transitions between the different zones
  • Adapt quickly to your new glasses
  • Capture all close-up information clearly
  • Reduced image distortions across all vision zones

The Path Optimizer technology

Optimised for each wearer, the Path Optimizer will generate, without any extra measurements, a precise and optimal viewing path from far to near. Each part of the viewing path will match the wearer's gaze direction.

Patient benefits

  • Clear vision at any distance with a wider near vision zone: the design is optimised for each addition taking into account the changing needs of wearers.
  • Easy adaptation: wearers will experience a smooth transition between the three central zones, making it easy to adapt to the design.
  • Keep to Varilux digital quality: wearers looking for an entry-level Varilux lens benefit from digital surfaces, guaranteeing the performance of the design.

Lens protection with Crizal Easy Pro

Crizal Easy Pro coating provides protection against UV light and is anti-reflective, scratch-resistant, smudge-repellent, water-repellent and dust-repellent.

Comfort Max

Comfortable, sharp vision from the moment you put them on. Varilux Comfort Max lenses give you peace of mind whenever you put on your glasses.

  • Adapt quickly to your new glasses
  • Reduced image distortions across all vision zones
  • Comfortable vision from the moment glasses are put on

Increased Postural Flexibility

With Varilux® Comfort Max lenses, wearers can adopt 495 different body postures when looking at a computer or desktop screen vs 237 with the previous generation of Varilux® Comfort. This is why Varilux® Comfort Max lenses provide a wider range of natural postures to see a given vision target, providing more comfortable vision all day long.

Live Optics

Varilux Comfort Max lenses have been designed using Essilor's exclusive "Live Optics" Research & Development technique, which considers wearer physiology and optics, following which a full evaluation of the design through detailed wearer tests is conducted.

Flex Optim™ Technology

Flex Optim™ technology ensures that Varilux Comfort Max lenses are adjusted to each individual beyond their vision profile.

Physio 3.0

Varilux lenses deliver high-resolution vision whether you’re looking at something close up, far away or anything in between.

  • Clarity of vision at all vision distances: near, far and everything in between
  • Adapt quickly to your new glasses
  • Seamless transitions between seeing zones
  • Reduced image distortions across all vision zones

Wave 2.0 Technology

A design innovation which maps pupil size whilst utilising the latest wavefront technology.

  • Coma control to reduce higher-order aberration
  • Axis control to keep the axis of unwanted astigmatism vertical in order to meet the eye preference
  • Power control to extend vertically the zone of stabilised near power

In addition to analysing the entire beam of light, the lens calculation now integrates every possible pupil diameter.

Binocular Booster

80%* of presbyopes have a different prescription for left and right eyes. This visual gap requires our brains to work harder to merge retinal images. The new Binocular BoosterTM technology manages this difference along the meridian line, providing effortless vision through perfectly seamless transitions between near and distance vision zones.

Digital surfacing

Varilux Physio 3.0 are manufactured using digital surfacing, ensuring the lens's performance is optimised.


Distance glasses with near vision correction normally in a 'D' segment.



The shape of the reading segment in these lenses is in the shape of a 28mm diameter circle. Ideal for prescriptions with positive figures.



The reading segment in these lenses is in the shape of the letter D with its flat side uppermost. This segment has a flat top and a curved bottom. These are the most common type of bifocal, they are extremely successful as the reading area is very stable.



Similar to the D28 flat top bifocal with the reading segment in the shape of the letter D, however, these lenses have a larger reading segment (35mm) compared with the D28 design, they are extremely successful as the reading area is very stable.



This bifocal segment is in the shape of the letter C with a slight upward curve at the top of the segment. Less light is reflected from the segment top, therefore cosmetically more appealing than flat top segments.
