What Are Varifocal Lenses?

Published

on

As people age, eyesight changes are almost inevitable. Tasks such as reading a book, working at a computer, or driving in darker environments can become more difficult. One of the most common causes is the eye condition presbyopia, which reduces the eye’s ability to focus on close objects. Traditionally, this meant owning more than one pair of glasses to correct vision at different distances. Today, however, there is a more convenient option: varifocal lenses. But what are varifocal lenses, and how do they help people struggling with poor vision at various ranges?

If you are considering upgrading your eyewear, hoya varifocal lenses provide an advanced solution designed to deliver clear vision across near, intermediate, and far distances in the same pair of glasses.

Understanding Varifocal Lenses

Varifocal lenses, also known as multifocal lenses, are specially designed lenses that allow wearers to see clearly at different distances without switching between two pairs of glasses. Unlike bifocals, which have a visible line separating distance vision from reading distance, varifocals offer a seamless design. This means the transition between zones is gradual, providing continuous vision without sudden changes.

The top of the lens is set for distance vision, useful for driving or spotting objects far away. The middle section supports intermediate distances, such as looking at a computer screen. Finally, the lower section is designed for reading distance, making it easier to focus on books, menus, or a phone screen.

This smooth progression makes varifocal glasses feel like a single lens that adapts to your needs. Wearers can look up, ahead, or down and see clearly without the inconvenience of changing frames.

Why Varifocal Glasses Are Popular

The main attraction of varifocal glasses is convenience. Instead of carrying more than one pair of glasses, wearers can rely on the same pair for every task. Whether you are working on a laptop, reading, or walking outdoors, you only need one frame and one prescription lens.

Varifocal options are particularly helpful for people who want to avoid the frustration of constantly switching between two pairs. They also offer a more modern appearance compared with bifocals, as there is no visible line across the lens.

For many customers, varifocal glasses provide the perfect pair because they combine practicality with style. With the right frames, they look just like standard glasses or even sunglasses, while still correcting vision at different distances.

The Difference Between Varifocals and Other Lenses

The key difference between varifocal lenses and single lens glasses lies in functionality. A single lens prescription corrects either near or distance vision, but not both. This often means struggling with tasks at other ranges.

For example, if you have reading glasses, you might achieve clear vision at close range but experience blurred vision when looking across the room. On the other hand, distance glasses may help with driving but leave you struggling to read a menu.

Varifocals resolve this issue by blending powers into the same pair, allowing smooth transitions between distances. This design reduces the need to carry multiple frames and creates a more convenient experience for daily life.

How Varifocal Lenses Work

The design of varifocal lenses is precise. Power gradually changes from the upper section down to the lower section, creating zones tailored for specific distances. The middle section plays a vital role, covering intermediate distances such as computer work or viewing objects at arm’s length.

While this progression creates continuous vision, it can take a few weeks for new wearers to adapt. The eyes, head, and even posture may need slight adjustments as you begin using your new lenses. Some people initially notice distortion at the edges or mild eye strain, but with consistent wear, most symptoms fade.

Opticians usually recommend wearing varifocals full-time to help your eyes adjust. By avoiding frequent switching to older frames, the brain learns how to process the gradual change in power more quickly.

Adapting to New Varifocals

Adapting to new varifocals can feel different from putting on single vision glasses. At first, wearers might experience blurred vision in the periphery or feel concerned about distortion when moving their head. Some also report headaches or discomfort while adjusting.

The best way to adapt is to wear your glasses consistently. Try using them across all tasks, including reading, computer work, and walking outdoors. With time, your eyes will adjust to the continuous vision. Most customers begin noticing improvement after a few days, while full adjustment may take several weeks.

If symptoms such as eye strain or headaches persist beyond this period, it’s important to visit your optician for a review. They can check whether the prescription or lens design needs adjustment.

Everyday Examples of Varifocals in Use

Imagine driving at night. The upper section of the lens helps you see the road clearly, while the middle section allows you to check the dashboard without struggling. When you glance down to read directions on your phone, the lower section comes into play. This flexibility means you don’t miss a moment.

Another example is office work. You might be looking across a meeting room, checking your laptop screen, and reading notes all within minutes. Varifocal glasses make these transitions smooth without the need to carry two pairs of glasses.

Even simple tasks like shopping become easier. You can check signs in the distance, read labels on shelves, and review your shopping list using the same pair.

Things to Be Aware Of

While varifocals are convenient, it’s important to be aware of certain features and potential concerns.

  • Distortion at the edges: The design of varifocals can sometimes create slight blur in the periphery. Most wearers adapt quickly, but it can feel unusual at first.
  • Adjusting head movements: You may need to move your head rather than your eyes to access the correct section of the lens. For example, tilting downwards for reading distance or straight ahead for far objects.
  • Cost: Varifocal lenses can be more expensive than standard single vision glasses because of their complex design. However, they often save money in the long run, as you don’t need two pairs.
  • Adaptation period: Not everyone adapts at the same speed. Some people find the process quick, while others may take weeks.

Being prepared for these factors helps customers set realistic expectations and get the most from their new lenses.

Choosing the Right Varifocal Options

Not all varifocals are the same. Lens design varies in terms of how smoothly the power changes, how wide the intermediate area is, and how distortion is managed. High-quality designs typically provide wider fields of clear vision and less distortion at the edges.

Your optician can recommend the most suitable lens based on your prescription, lifestyle, and budget. For example, someone working long hours at a computer may need a design with enhanced intermediate distances. Those who spend more time outdoors might prefer varifocals combined with sunglasses.

When selecting frames, comfort is essential. Frames should sit properly on the head without slipping, as positioning affects how you access each section of the lens. A poor fit can make it harder to adjust.

Presbyopia and the Need for Varifocals

Presbyopia is a natural part of ageing and usually begins around the age of 40. It affects the flexibility of the lens inside the eye, making it harder to focus on close tasks. While some people try to manage by switching between two pairs of glasses, varifocals often provide the most convenient solution.

By combining distance, intermediate, and reading correction into the same pair, varifocals reduce the hassle of carrying multiple frames. This means you can read, drive, work, and relax without interruption.

Reviews and Customer Experiences

Many wearers say that adapting to varifocals was easier than expected and that they enjoy the convenience of using one pair of glasses for every task. Customers often highlight how varifocals reduce eye strain, particularly when switching between tasks like reading and computer work.

However, reviews also show that the adaptation period can be challenging for some. Symptoms like blurred vision or headaches may appear at first, but most people report that these ease after consistent wear.

The key is to follow your optician’s advice, wear your new varifocals regularly, and allow time for your eyes to adjust.

Final Thoughts

So, what are varifocal lenses? They are advanced multifocal lenses designed to correct presbyopia and other vision needs by blending different powers into one single lens. Instead of owning two pairs, wearers enjoy clear vision at different distances with the same pair of glasses.

While they may feel unusual at first, the long-term benefits include continuous vision, fewer symptoms of eye strain, and greater convenience in everyday tasks. Whether you are reading, working on intermediate tasks, or focusing on distance vision, varifocals provide the perfect pair to suit every moment.

With expert guidance from an optician and the right lens design, varifocals make life easier for people who would otherwise struggle with blurred vision or poor vision as they age. For those diagnosed with presbyopia, they remain one of the best ways to enjoy clear sight across all distances.

From platforms to people: The next era of femtech

Published

on

By Katrina Zalcmane, head of partnerships and growth, Véa

The next era of femtech shifts focus from platforms to people as women rethink how technology fits into wellness and social life.

Women are spending less time on ambient, always-on digital environments and more time in bounded, intentional, in-person settings.

This is not a rejection of technology but a reprioritisation of how and where it belongs. For femtech, this shift is not cosmetic. It signals a structural change in user expectations – one that has implications for product design, engagement models and long-term relevance. 

I explore three key signals underpinning this shift: reduced engagement with social media platforms, the resurgence of in-person, women-led communities and growing fatigue with fragmented digital tools.

Signal 1: Declining Engagement With Social Platforms Among Women

Multiple data sources point to a flattening or decline in engagement with traditional social media platforms, particularly among women:

  • Pew Research Center reports that adults are increasingly “actively limiting” their social media use, with women more likely than men to cite emotional exhaustion and reduced wellbeing as reasons.
  • Ofcom’s Online Nation report shows year-on-year declines in time spent on social platforms among UK women aged 25–44, alongside rising use of messaging and offline coordination tools.
  • Meta itself has acknowledged a shift away from “social graph” engagement toward private, smaller-group interactions in recent earnings calls.

While this is not mass abandonment, it does indicate selective withdrawal: fewer platforms, less ambient presence, more intentional use.

Signal 2: The Rise of In-Person, Women-Led Communities

At the same time, participation in physical, community-based activities has increased. Examples include:

  • the growth of women-led run clubs and fitness collectives across major cities, often operating independently of digital platforms;
  • the expansion of paid, small-scale retreats and circles focused on reflection, creativity or embodiment;
  • increased demand for local, recurring group experiences rather than one-off events.

While women are stepping back from social platforms, they are stepping into real-world communities. ONS data on social capital shows a post-pandemic rebound in in-person participation, particularly among women aged 25-45, with a preference for smaller, repeat gatherings over large social events.

What distinguishes this wave of community-building is intentionality. These spaces are bounded, often invitation-based and deliberately offline.

They are designed to counteract overstimulation rather than add to it.

Signal 3: Tool Fatigue and the Consolidation of Digital Habits

Alongside social media fatigue, there is growing evidence of “tool fatigue” across wellness and productivity categories:

  • App retention rates across health and wellness remain low, with industry benchmarks showing that fewer than 25 per cent of users remain active after 30 days.
  • Deloitte’s Digital Consumer Trends report notes a move toward app consolidation, with users preferring fewer, multi-purpose tools over fragmented stacks.
  • Qualitative studies show women are particularly sensitive to cognitive overload caused by managing multiple apps for mood, cycles, health, reflection and social coordination*.

The implication is not that women want less support but that they want smarter, simpler tools that can actually help manage their inner lives.

What This Means: A Shift in the Role of Technology

Taken together, these signals point to a clear trend: technology is moving from being a primary site of social life to a supporting layer around it.

Women are not asking apps to become communities. They are asking them to:

  • help them reflect and process privately;
  • reduce cognitive and emotional clutter;
  • support real-world relationships rather than replace them;
  • operate in bounded, intentional ways.

This reframes success metrics. Engagement time and daily active use become less meaningful than whether a tool genuinely increases capacity, clarity and presence outside the app.

Implications for Femtech

For femtech, this marks a decisive transition. The first phase of femtech focused on visibility: tracking cycles, symptoms and bodily data that had previously been ignored.

The next phase will focus on integration: helping women make sense of experience in ways that support how they live, relate and gather.

Femtech products that attempt to:

  • replicate community digitally,
  • build social feeds under the banner of wellbeing,
  • position AI as a substitute for real connection,

risk misaligning with where behaviour is actually moving. 

By contrast, femtech that treats technology as infrastructure, not destination, is better positioned for longevity.

Where Véa Fits

Véa was built with this shift in mind.

Rather than attempting to replace connection or build another social layer, Véa focuses on internal processing – neuroscience-backed journaling, emotional pattern recognition and reflective AI support – so that women can show up more clearly in their real lives.

Importantly, Véa is not only a digital tool.

It is designed to extend into physical space, through curated in-person experiences and community gatherings that prioritise presence, embodiment and shared reflection.

The digital layer exists to support the human one, not compete with it. In a context of tool fatigue and selective disengagement, this hybrid model – digital support paired with real-world interaction – aligns closely with how women are choosing to engage today.

Over the next decade, the most resilient femtech products will not be those that maximise time spent inside ecosystems but those that give women back the capacity to return to their lives – with greater clarity, energy and real-world connection.

It’s time to design femtech that empowers presence over engagement.

How Women in Tech Switch Off Without Switching Off

Published

on

Modern tech work blurs the boundary between focus and fatigue. Notifications spill into evenings, side projects jostle for attention, and the same screens we use to ship code stream our downtime. The answer is not to disconnect completely. It is to design small, protective rituals that restore energy while keeping a gentle sense of control. Short, low pressure restorative online play can sit alongside other evening habits without draining tomorrow’s focus.

Make Recovery a Feature, Not a Fix

Burnout rarely arrives in a single moment. It builds through micro stresses that never get cleared. Treat recovery as a product feature you ship every evening, simple and reliable rather than grand and rare. Start with boundaries that mark the end of the workday. Close the laptop, write a one line note about tomorrow’s first task, and put your kit out of sight. That single gesture creates a clean edge the brain respects.

Then change the environment. Shift lighting from cool to warm, swap the chair for the sofa, and set your phone to a calmer home screen. These cues matter. They tell your nervous system the mode has changed so you can mix mental rest with light engagement that still feels intentional.

Short, Screen-literate Rituals That Actually Work

  • A ten minute mobility or stretch video resets posture after hours at a desk
  • A tidy loop, like clearing the downloads folder or filing screenshots, reduces digital noise
  • A breath guided practice that ends on the dot gives a measurable downshift
  • A single chapter of a book or a short podcast episode keeps attention light and finite

When energy is low, aim for the smallest possible win. Two minutes of breathing still counts. One drawer tidied is still progress. Preserve the shape of recovery rather than chasing perfection.

Where Light Online Play Fits

Play is a human need, not a teenage phase. In the right dose it helps down regulate stress and restores a sense of agency after a day of reacting to tickets and pings. Keep it light and bounded. Choose modes that resolve in fifteen to twenty minutes, mute work apps, and set a visible stop time before you start. The aim is a calm, finite session that ends cleanly.

Cosy builders, puzzles, or narrative adventures often deliver novelty without social pressure. If you prefer something social, co-op rounds that finish quickly provide connection without dragging the night. Headphones with a gentle volume limit protect shared spaces and evening quiet.

Pair play with tiny chores so life runs smoother. Start a short download, fold laundry while it completes, then enjoy your round guilt free because the house already feels calmer. This is deliberate energy management, not indulgence.

Design a Space That Calms On Sight

  • Put a warm lamp on a simple timer so evenings do not begin under harsh light
  • Keep controllers, headphones, and chargers in one tray so play starts cleanly and puts away fast
  • Use a standing phone dock during dinner to avoid reflex checks
  • Keep the bedroom device light and cool in tone so your brain associates the space with sleep

If you live with others, make the evening rhythm visible. A shared quiet hours note, a soft household wind down alarm, and a last call for dishwashing help everyone respect the boundary between work and rest.

A Weeknight Template That Holds Under Pressure

  • Shutdown: one line for tomorrow, close tabs, quick desk tidy
  • Reset: ten to fifteen minutes to settle the kitchen and lay out morning basics
  • Nourish: simple dinner that keeps cleanup minimal
  • Reward: one short activity on a timer, with light online play as an option
  • Wind down: warm lights, gentle stretch, phone on do not disturb, consistent lights out

If you miss a step, shrink it rather than skipping the whole routine. Small completions compound. Over a month they beat heroic bursts every time.

Leadership Starts With Example

Team norms shape personal wellbeing more than any tool. If you manage others, model sane hours and visible shutdowns. Delay send late emails, publish focus blocks, and praise outcomes over urgency theatre. Encourage short, restorative breaks through the day so evenings do not have to undo quite as much. When leaders normalise humane rhythms, teams follow and results improve because people are not running on fumes.

Why period pain feels worse in winter

Published

on

By Ruby Raut, founder and CEO, WUKA

If you have ever noticed that your cramps feel sharper, your mood dips harder, or your energy seems to disappear during the colder months, you are not imagining it. Winter can genuinely make periods feel more painful and more difficult to manage. The combination of cold weather, less sunlight, increased tension in the body, and reduced activity creates the perfect storm for stronger cramps and heavier emotional symptoms.

Understanding why this happens gives you the power to manage your cycle with more confidence. Here is the most digestible explanation of why winter and period pain are so closely linked.

Cold weather tightens blood vessels

When temperatures drop, your body goes into protection mode. To conserve heat, it tightens your blood vessels, especially around your hands, feet, and lower abdomen. While this is a smart survival response, it comes with an unwanted side effect for menstruation.

Your uterus is a muscle. Like any muscle, it needs good blood flow to relax and function smoothly. When the blood vessels around your pelvis tighten, circulation naturally becomes slower. Less blood flow means the uterus has to contract harder to shed its lining, and this can make cramps feel deeper, sharper, and more persistent.

This is why heat has always been one of the most effective comfort tools during a period. Warmth helps blood vessels open again, improves circulation, and relaxes the muscle of the uterus.

Your muscles tense up in the cold

Cold weather does more than chill your skin. It makes your whole body tighten without you even realising it. Think about how your shoulders creep upward when you step into the winter air or how your spine curls slightly for warmth. The same tension can build in your abdomen and pelvic floor.

Tighter muscles mean more resistance against the natural contractions of the uterus. When everything around the uterus is tense, cramps can feel more intense and more difficult to soothe. Even mild pain can feel magnified when the surrounding muscles are already stiff.

This is one of the reasons gentle movement, stretching, and warm baths can make such a difference during winter periods. Anything that eases tension also eases pain.

Less sunlight affects your mood and pain perception

Winter brings shorter days and longer nights, and that naturally reduces your exposure to sunlight. Sunlight plays a key role in regulating serotonin, the hormone that helps stabilise mood and influences how we experience pain.

Lower serotonin can lead to lower energy, stronger mood swings, and more emotional sensitivity. Because serotonin also impacts the way the brain processes discomfort, low levels can make cramps feel more intense.

This emotional shift can make PMS symptoms feel heavier too. Irritability, sadness, and bloating can all feel amplified during the colder months, creating a cycle that feels harder to manage.

Winter usually means less movement

Colder months naturally lead to less physical activity. We walk less, we spend more time indoors, and many people find it harder to stay motivated to exercise. While rest is important, the lack of movement has a direct impact on period pain.

Moving your body improves blood circulation and reduces inflammation. When you sit for longer or avoid movement due to cold weather, blood flow becomes slower and inflammation can rise. Both of these factors contribute to stronger cramps.

Even gentle activity makes a difference. A short stretch, a ten minute walk, or simple breathing exercises that open the chest and abdomen can support circulation and ease pain.

Prostaglandins may spike in colder weather

Prostaglandins are natural chemicals that help the uterus contract during menstruation. Higher levels are linked to stronger cramps and heavier flow. Some research suggests that colder temperatures and lower physical activity may increase the production of prostaglandins, although this varies from person to person.

This means that the natural winter slowdown combined with the physical effects of cold weather can lead to more intense uterine contractions, which again results in more painful periods.

How to make winter periods easier

The good news is that small, accessible habits can make a big difference to how your body feels during winter.

Use warmth generously

Heat patches, warm showers, hot water bottles and cosy clothing help open up blood vessels and soothe the uterine muscle.

Move your body even a little

Short walks, stretching routines or low impact workouts help improve circulation and reduce inflammation.

Support your mood with sunlight

Get outside during daylight hours whenever possible. Sitting near windows or using a light therapy lamp can also support serotonin levels.

Eat warming and nourishing foods

Soups, ginger, turmeric and herbal teas help comfort the body and may reduce inflammation.

Choose period products that keep you comfortable

Secure, breathable period underwear can help you feel more relaxed and confident, especially when your body already feels tense from the cold.

Winter does not have to mean more painful cycles.

With warmth, gentle movement, and an understanding of how your body responds to the season, you can navigate cold month periods with more comfort and control.
