Adapting To Varifocals - Expert Tips For A Smooth Switch

As we reach our 40s and 50s, many of us start to notice a change in our close-up vision - reading a book, checking a phone, or threading a needle suddenly feels harder. This natural, age-related condition is called presbyopia. It occurs when the eye’s lens loses flexibility, making it difficult to focus on objects up close.
To manage both near and distance vision, many people first turn to separate pairs of reading and distance glasses. But constantly switching between them can be inconvenient.
That’s where varifocals, also known as progressive lenses, offer a convenient solution.
Varifocals incorporate multiple vision zones in one seamless lens: distance at the top, intermediate in the middle (for tasks like computer work), and near vision at the bottom. They eliminate the need for multiple pairs and avoid the visible lines found in bifocals.
However, adjusting to varifocals can take time.
Your eyes and brain need to learn how to use the different parts of the lens effectively. With the right guidance, most people adapt quickly and enjoy the clear, uninterrupted vision that varifocals provide.
We’ve put together our top tips and advice to help you transition smoothly and confidently to quickly get used to your new varifocal glasses.
What Are Varifocal Glasses & How Do They Work?
Varifocal glasses are a type of multifocal lens that gradually changes power from top to bottom, designed to correct vision at different distances seamlessly.
The top portion of the lens helps with distance vision (e.g. driving, watching TV), the middle (intermediate) zone helps with tasks like computer work or looking across a desk, and the lower section is for close-up tasks like reading or knitting.
Unlike bifocal lenses, varifocals don’t have visible lines, so they look more like standard single‑vision glasses, while offering vision correction at all ranges.
Why Adapting to Varifocals Takes Time
When you first put on varifocal lenses, it’s common to feel slightly disoriented or uneasy. This isn’t because the lenses are flawed or your prescription is wrong, it’s because your brain is acclimatising to a new way of seeing.
The bottom and peripheral regions of varifocal lenses tend to create distortion or blur when you look sideways or down, a phenomenon often referred to as “swim and sway.”
These distortions can make walking, going down stairs, or even turning your head feel strange at first. For that reason, many opticians recommend giving yourself time, usually a few days to a few weeks, to allow your brain and eyes to adjust to the new prescription.

Our Top Tips For The Best Transition to Varifocals
Here are tried‑and‑tested recommendations to help you adapt more comfortably and quickly:
Wear them as much as you can: The best way to adjust is simply to keep your varifocals on consistently. Switching back and forth between old glasses and varifocals confuses your brain, delaying adaptation.
Use your head, not just your eyes: When you look at something nearer or further away, move your head accordingly rather than just shifting your eyes. This ensures you’re looking through the correct part of the lens and reduces distortion or blur.
Start indoors and with simple tasks: Begin wearing your varifocals at home before venturing out. Try reading, watching TV, walking around, or doing everyday tasks first. Once comfortable, gradually use them for more demanding tasks like walking on uneven ground or going outdoors.
Be patient and give it time: Most people adapt within one to two weeks; for some, it might take up to a month.
Get your glasses adjusted if needed: If discomfort, distortion, or dizziness persists well beyond a few weeks, it may be worth visiting your optician for an adjustment. Sometimes the problem is not the lenses, but how they sit in your frames.
The Importance of Proper Fitting for Varifocal Glasses
Getting varifocals to work properly isn’t just about the lenses; how they sit in front of your eyes matters too. Poorly fitted frames or incorrect lens alignment can severely hamper the effectiveness of varifocals, even if prescription and lens design are spot‑on.
That’s why it’s worth paying attention to:
The size and shape of the frames: they should suit your face and sit comfortably without sliding down your nose.
The vertical positioning of lenses: they should align so that the different zones (distance, intermediate, near) match natural eye movement comfortably.
The overall fit and comfort: lenses should sit evenly and securely, avoiding tilt or misalignment, which can cause distortions or headaches.
If you're unsure whether your glasses are correctly fitted, we recommend visiting our Fitting Your Glasses Guide. It’s packed with helpful tips to ensure your frames are positioned just right for varifocal lenses, supporting optimal clarity and all-day comfort. A well-fitted pair of glasses can make all the difference when adapting to varifocals.
Why PD Measurement Matters
One of the most critical measurements when getting varifocal glasses right is your pupillary distance (PD). Luckily, this can be easily measured using a PD measurement tool.
This is the precise measurement between the centres of your pupils, and it directly determines where the optical centre of each lens should sit within your frames.
For varifocals to function properly, each vision zone must be aligned with your natural line of sight as your eyes shift between distances throughout the day.
This level of precision makes PD measurement far more critical for varifocals than for single-vision or bifocal glasses. While those lens types can tolerate small errors, varifocals are much less forgiving. Even a slight misalignment can lead to blurry vision, eye strain, or trouble focusing between tasks, all of which can make the adjustment period unnecessarily difficult.
To ensure your varifocals perform as they should, getting your PD right is essential. It can be measured by an optician with a simple millimetre ruler or with our easy-to-use online tool.
When Your Lenses May Need Adjustment
While some mild blurriness or minor distortion is normal at first, there are times you should consider getting your varifocals checked:
Persistent dizziness, nausea, or motion sickness after several weeks of use.
Ongoing headaches or eye strain after routine wear.
Continual blurriness when you look through certain zones of your lenses.
Difficulty walking, using stairs, or navigating curbs because of distorted vision.
If you experience these, even after giving yourself several weeks, it’s worth revisiting your optician. Sometimes the issue is not the lenses themselves, but misalignment, incorrect PD, or frame fit. A proper refit can make a big difference.

Can Reglazing Work with Varifocal Lenses?
Reglazing is the process of fitting new lenses into your existing frames, a great option if you love your current glasses but need an updated prescription or want to switch to a different lens type, such as varifocals. It’s a cost-effective and environmentally friendly way to make sure your lenses are up to date without buying an entirely new pair of glasses.
Varifocal lenses can be reglazed into most frames, provided they’re in good condition and fit your face comfortably. Because varifocals rely on precise alignment for each vision zone to work correctly, accurate measurements like pupillary distance (PD) are just as important as when ordering a brand-new pair.
Our reglazing service makes it simple to upgrade to varifocals using your existing frames, with expert fitting to ensure clear, comfortable vision from the moment you put them on.
Final Thoughts
Switching to varifocals is a major step toward hassle‑free eyewear. Once you’ve given your eyes and brain time to adjust, most wearers find the convenience of having one pair of glasses for reading, screen work, driving, and daily life is well worth the short transition period.
With careful fitting, accurate measurements (especially PD), and a little patience, varifocal glasses become a reliable, comfortable companion, offering clear vision at every distance and a renewed sense of visual freedom.
