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.

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.

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

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.
XR Design
A progressive lens that truly understands your eyes. Powered by artificial intelligence, it predicts how you naturally look at things, giving you instant clarity - even in motion, and seamless transitions across all distances.
Key Benefits
- Instant sharpness, even in motion
- Natural posture and comfortable close-up vision
- Stabilised vision for demanding situations
- High visual acuity in low light
- Wide, panoramic fields of view
How It Works
Eye movement isn’t strictly linear, but most progressive lenses assume it is, making rapid focus changes challenging. Varilux® XR Design™ lenses use over 1 million wearer data points to anticipate real-world eye movement, optimising your vision based on how you actually see - not just your prescription.
As a result, you’ll notice sharper, more fluid vision throughout the day, with effortless shifts from near to far. In fact, 79% of wearers report better overall vision than with their previous varifocals, and 95% adapt within the first day.
Cutting-Edge Technologies
- XR-motion™: Personalises each lens to your prescription and predicted eye movements.
- Nanoptix®: Reduces peripheral distortion and the “swim” effect.
- Xtend®: Merges near and intermediate zones for clear vision at arm’s length.
Your eyes can move over 100,000 times a day - Varilux® XR Design™ is designed to keep up, delivering the comfortable, dynamic vision modern life demands.
双光镜片
Distance glasses with near vision correction normally in a 'D' segment.
R28的圆形双光镜片
The shape of the reading segment in these lenses is in the shape of a 28mm diameter circle. Ideal for prescriptions with positive figures.
D28的平顶双光
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.
D35的平顶双光
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.
C28曲顶双光
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.
