Disclaimer: Although many wearers of blue light glasses report positive effects, scientific studies are yet to show findings that correspond to these claims. 

The first thing that pops into your head if someone mentions “looking after yourself” is probably eating well, exercising or maintaining a healthy social life.

These are all important, of course, but nowadays, looking after yourself goes beyond these traditional pillars. 

With technology and screen time dominating our waking hours, digital wellness is a topic that comes up more and more, and having the right eyewear can help keep yours in check.

What are blue light-blocking multifocal lenses?

These multifocal glasses have a blue light-blocking coating and three different prescriptions within them for your near, intermediate and distance vision.

The three prescriptions allow you to see at each of these distances without having to change your glasses, while the coating protects your eyes from blue light emitted from screens. 

Screens, as well as the sun, are a source of blue light. This light isn’t bad for us in small doses, but in this day and age, we rely on screens so heavily that the amount of exposure to blue light is no longer ideal. 

If you spend a lot of time in front of a computer screen or your phone, for example, then having one pair of glasses that can switch between distances and simultaneously protects your eyes will be beneficial – for your vision and the convenience.

Extended exposure can cause eye strain, discomfort and various other issues. However, it’s possible to add a blue light filter to any pair of glasses, including your multifocals.

Blue light can also be good for us and our brains so we shouldn’t fully block it out. The right amount can improve memory, cognition and elevate your mood, especially for those who live in countries with shorter winter days or long periods without daylight.

Why should I add this lens coating to my multifocals?

Having blue light progressive lenses is suitable for anyone who spends time in front of a screen or outdoors in the sun.

You can wear these when you’re doing computer work, scrolling through your phone, or watching television

Adding this lens coating to your prescription glasses poses no adverse effects to your vision.

So, you can leave them on all day to complete your daily tasks, even when you’re not in front of a screen.

Apart from preventing eye strain, there are other benefits regarding wellness that blue light lenses provide.

Relieve digital eye strain

Multifocal glasses with blue light-filtering may relieve digital eye strain which will help you to feel better in more ways than one.

Digital eye strain can cause headaches, neck, back and shoulder pain and dry eyes. 

Not only does relieving eye strain minimise these symptoms, but it can result in better concentration too. 

Better sleep and mental health

Blue light has a major impact on our circadian rhythm. 

Circadian rhythms are 24 hour internal clocks within our bodies that help us to function. The circadian rhythm affected by blue light is the sleep-wake cycle. 

Exposure to too much of this light can interrupt the sleep-wake cycle, as it signals to your body to be awake and alert. 

Just like darkness signals relaxation and sleep. Too much may suppress the melatonin which will keep you up at night. 

Poor sleep hygiene will not only leave you feeling tired and sluggish, but it can contribute to depression and anxiety and affects your hormone regulation. 

Due to work, social media, your favourite Netflix series, etc. it can be difficult to minimise your screen time.

But by adding a blue light- filter to your lenses, you may be able to reduce the amount of blue light that your eyes take in which could improve your sleep

Improving your sleep pattern will not only have you ready to take on the day, but the regulation of your hormones could help your mental health too.

Higher productivity

Another benefit to sorting out your sleep-wake cycle by reducing the effects of blue light is higher alertness and productivity. 

This can do wonders for many reasons. 

Not only will you perform better at work as you’re able to concentrate (with less eye strain, might we add) but having better productivity at work can positively impact your self-esteem, confidence and your work-life balance. 

Improving your digital wellness with a pair of blue light lenses can benefit your physical, mental and emotional well-being. 

Extra tips for improving digital wellness

Apart from multifocal lenses with blue light-filtering, here are some extra steps you can take to provide visual comfort, mental clarity and better physical health, when being exposed to screens!

  • 20-20-20 rule – every 20 minutes, take a 20-second break from your screen and focus on something 20 feet away. 
  • Avoid screen time 1-2 hours before bed to wind down. 
  • Regular trips to the eye doctor to keep your progressive prescription up to date so you’re always able to see clearly at each distance. This should generally be every 2 years, but can vary depending on your age and eye health history.
  • Use eye drops if you’re experiencing dry eyes from staring at your screen
  • Daily exercise for health, hormone regulation and a digital break!

Charting the Rise of Clear Frame Glasses

Charting the Rise of Clear Frame Glasses

Clear-frame glasses have quietly ascended to prominence in the eyewear fashion world, transforming from a niche trend to a mainstream staple. 

This evolution reflects a broader shift in fashion towards embracing minimalist and versatile accessories.

When did clear frames become popular?

The popularity of clear frames began to surge in the early 2010s.

This rise was fueled by a growing interest in minimalist fashion, where the emphasis on simplicity and functionality matched perfectly with the understated elegance of clear frames. 

Fashion designers and influencers quickly adopted and promoted clear frames, highlighting their versatility and modern appeal.

This trend was also supported by advancements in materials and design, allowing for more durable and stylish options.

Are clear glasses in style for 2024?

They’re as in as avocado toast at a Sunday brunch. Looking ahead to 2024, transparent frames continue to be a significant trend in eyewear fashion. 

Their appeal lies in their timeless design and adaptability to various fashion sensibilities.

The ongoing focus on sustainability in fashion has also played a role in the popularity of clear frames. 

Many are now made from eco-friendly materials like eco-plastic or recycled acetate, appealing to environmentally conscious consumers.

How to style clear-frame glasses

They say less is more, and clear frame glasses took that advice literally – they’re the embodiment of minimalist chic, minus the try-hard.

Why? Because they’re transparent so they go with everything! What you need to focus on is choosing a pair that suits your face and personality.

  • Choose the right shape: Clear frames come in various shapes, including round, square and cat-eye. Experiment with different styles to find the one that suits your facial features best.

  • Pay attention to details: Clear frames often feature unique design elements, such as metal accents or coloured edges. These details can add something extra to your look, so consider them when choosing your pair.

  • Consider your complexion and features: Although clear, these glasses can influence how your complexion and facial features appear. Select a frame thickness and shape that enhances your natural features, considering how the frames cast light and shadow.

  • Coordinate with accessories: Match your clear frames with minimalist jewellery or watches to maintain a modern and sophisticated style.

Seeing through the trend

Clear-frame glasses have perfectly balanced versatility and minimalism, offering another choice to all metal-frame wearers who chase that one pair that goes with everything.

That’s right! We may be witnessing the rise of clear frames as more than just a fleeting trend but rather a timeless choice in the evolving narrative of eyewear fashion.

Eye yoga aims to mitigate eye strain and enhance focus through targeted exercises.

Please note: while eye yoga can be beneficial for alleviating eye strain and improving focus, there’s no scientific evidence that it can resolve or improve any vision conditions.

In today’s digital age, our eyes are under more strain than ever, leading to increased eye fatigue, dryness and discomfort. 

Eye yoga can be a valuable, holistic way to help mitigate these symptoms. While reading the article, try the exercises to learn how they work!

This type of yoga specifically targets the ocular muscles (the muscles around the eye). It consists of exercises designed to strengthen the eye muscles, improve focus and promote relaxation.

Benefits of eye yoga

No scientific proof supports that eye yoga can help improve vision conditions like astigmatism, myopia, or presbyopia (Bianchi and Bellen 2020). 

However, there is evidence that eye yoga might be helpful for improving your ability to focus and relieve eye strain.

A study conducted on a group of thirty-two undergraduate optometry students observed that ocular yoga exercises reduce eye fatigue symptoms by increasing the efficiency of the muscles around the eyes (Gupta and Aparna 2020).

Indeed, regularly engaging in eye yoga can lead to:

  • Reduced eye strain and fatigue, especially for those spending extended periods in front of screens.
  • Enhanced concentration and the ability to focus for longer periods.
  • Improved eye muscle strength, contributing to better control over eye movements.
  • Decreased dryness and irritation by promoting adequate eye lubrication.
  • Potential improvement in vision clarity by relieving tension in the eye muscles.
Benefits of eye yoga for eye health

Practice eye yoga exercises

Eye yoga involves performing different eye exercises, each targeting different aspects of eye health.

These exercises can be performed anywhere and anytime, making them a convenient option for those with busy lifestyles.

Why not give them a try as you read along?


Palming is a relaxing exercise designed to relieve eye stress and tension.

To practice palming, take a few deep breaths, rub your hands together until they feel warm, then gently cup your palms over your closed eyes, making sure not to apply pressure on your eyeballs.

The warmth and darkness help relax the eye muscles and the optic nerve, providing a soothing break for your eyes. Always make sure your hands are clean before starting this exercise.

Eye rolling

Eye rolling helps to strengthen the eye muscles and improve their flexibility by promoting mobility and circulation around the eyes.

To do this, sit or stand with your eyes open. Look up and slowly roll your eyes clockwise, making a full circle.

Repeat this movement 3-5 times, then perform the exercise in a counter-clockwise direction.

Eye yoga exercises

Focus shifting

Focus-shifting exercises enhance the ability to focus and refocus at different distances, improving overall eye function for near and distant viewing. 

Start by holding one arm straight out in front of you in a loose fist, with the thumb pointing up. Slowly bring the thumb closer to your nose until you can no longer keep it in focus. 

Then, slowly move it back to the starting position. Repeat this process several times to strengthen the focusing muscles of the eyes.

Blinking exercise

Blinking is a simple yet effective exercise for maintaining eye moisture and giving the eyes a much-needed break. 

We tend to blink less when working on screens, leading to dryness and irritation. 

Intentionally blinking every 3-4 seconds for two minutes can help refresh the eyes, improve focus and reduce eye strain.


Seven extraocular muscles around our eye control our eye and eyelid movements. By strengthening them with a few simple yogic eye exercises, we can help reduce eye strain and fatigue (Rizanti 2021).

More tips for healthy eyes

In addition to practicing eye yoga, consider incorporating these tips into your routine to support your eyes further:

  • Follow the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away.
  • Ensure proper lighting while reading or working to avoid straining your eyes.
  • Adjust the brightness and contrast of your screens to comfortable levels.
  • Keep your eyes hydrated by drinking plenty of water and using artificial tears if prescribed by your eye doctor.
  • Regularly visit an eye care professional to monitor your eye health and vision changes.

Discover how the multifocal lens came to be and how it’s been improved since its early days.

It’s not an exaggeration to say that ophthalmic lenses have changed the course of history, opening up a world of possibilities for the visually impaired, and giving them the chance to live much fuller lives.

Lens quality and technology have come a long way, and one significant advancement in this regard has been the development of multifocal lenses (also known as varifocal or progressive lenses).

As opposed to traditional lenses, multifocal lenses contain three different prescriptions, with each one blending seamlessly into the next. They give the wearer clear vision at near, intermediate and far distances when they look through the appropriate part of the lens. 

Although there is an initial adjustment period when wearing multifocal lenses, they have revolutionised the way individuals with presbyopia and other vision issues experience the world.

In this article, we will explore the history and evolution of multifocal lens design, from their humble beginnings to their modern, high-tech incarnations.

Bifocal lenses: the first multifocal lenses

Before multifocal lenses became a reality, people with presbyopia, a common age-related vision condition that impairs near vision, relied on bifocal lenses.

Bifocals, which were invented by Benjamin Franklin in the late 18th century, featured two distinct areas in the same lens, one for distance vision and the other for near vision.

However, the abrupt transition caused by the visible lines between these two zones was less than ideal, as it required wearers to adjust their gaze significantly when shifting from distant to near tasks.

The multifocal lens market was valued at $29.9 billion in 2021, highlighting how popular they’ve become.

The creation of the first multifocal lenses

Although already a big step forward from single vision lenses, the limitations of bifocals led to the development of multifocal lenses, which offer a smoother transition between viewing areas. So when were multifocal lenses invented?

The “invention” of multifocal lenses is not exactly straightforward. In 1907, British optometrist Owen Aves proposed a multifocal lens design and patented it.

Estelle Glancy patented another design for such lenses in 1924, and in 1955, Irving Rips produced a bifocal lens with a seamless transition. None of these went on to be commercially successful, so the legacy belongs to someone else.

French engineer Bernard Maitenaz generally gets the credit for the invention of the multifocal lens. He patented a design in 1953, which was then produced by Societé des Lunetiers (now Essilor) in 1959.

It was called the Varilux and was the first multifocal lens to be commercially successful, with further advances stemming from there.

Commercial production

The timing of Maitenaz’s multifocal lenses played a part in their success. Any previous production efforts had been very labor intensive.

It wasn’t until the mid-20th century that advances in technology allowed for more efficient and cost-effective production of early multifocal lenses. 

The introduction of computer-aided design (CAD) and precision machining in the 1970s greatly improved the manufacturing process.

This made multifocal lenses more accessible to a broader range of individuals, fueling their popularity.
