Did you know that we spend up to eight hours a day in front of a screen? – Whether watching series on the laptop or following friends and influencers on numerous social media platforms. You’ve probably also noticed that after this long time, our eyes get tired and some people even go to bed with a headache at night. But where does that actually come from? We will answer these and many other questions in this guide and give you a few tips on what you can do about it!


As already revealed in the title, we are talking about blue light. Our eyes are exposed to daily radiation from laptops, smartphones and tablets. The so-called high-energy blue light irritates our eyes and makes them tired with increasing use. As a result, many people feel tired and can hardly concentrate. In the long run, this light even damages our eyes.

But blue light not only affects our productivity – it can also disrupt our sleep rhythm, because the light prevents the production of the sleep hormone and the release of melatonin. Thus, our body does not receive signals that it is time to go to bed and falling asleep becomes more difficult.


Blue light consists of invisible light waves, just like UV light or infrared rays. The problem with light waves: The shorter the wavelength, the more harmful they are to our eyes. Blue light has a shorter wavelength than “visible light”, through which we can see the world in the colors we are used to, and can trigger eye diseases, concentration and sleep disorders or headaches. Most of it is emitted by our screens such as computers, smartphones or televisions.


Does this problem also apply to you and the use of these devices is an integral part of your everyday life? Then you’ve come to the right place! The solution to your problem is: blue light filter glasses! For all those who spend a large part of their daily time in front of a screen, whether professionally or privately, it is recommended to protect the eyes with blue light filter glasses, because these can filter blue light as well as UVA and UVB rays with their special coating.

And even people with poor eyesight get their chance, because we can also fit blue light filters to spectacles with prescription lenses. In addition to the filter coating, the glasses are then individually adjusted to your visual acuity between -8 and +4 as well as cylinder values between -2.5 and +2.5.


In addition to the huge range of modern frames from which you can choose, you can also determine the density of your lenses and choose between “thin”, “extra thin” and “ultra thin”. Our “thin” lens (index 1.6) is available at no extra charge. We don’t even offer you the standard lens (index 1.5) of other spectacle retailers, because we think you deserve more than standard! The “extra thin” (index 1.67) and “ultra thin” lenses (index 1.74) enhance your glasses in terms of density as well as with a lotus effect and an anti-static coating that protects your lenses from dust. Unfortunately, the processing of a blue light filter is technically not possible with the ultra thin glass.

We hope we’ve been able to clear up the question marks in your head about blue light and get you excited about the advantages of screen glasses. And if you should decide to buy one, you will quickly notice that your eyes are less tired and you are more efficient as a result! By the way, the glasses not only look good, but also sit lightly and comfortably on your nose – the perfect everyday companions!

Since Corona, home office has become the new normal for almost everyone, but this week we’re celebrating the official Work from Home Day! “What’s there to celebrate?”, some of you may be wondering now? Well, we’re going to show you! With a few little tricks, your home office time can almost be as exciting as time spent in the office. Except for your dear colleagues, whom you surely miss as much as we do.

1. Get out of those sweatpants!

We know how tempting it can be to slip straight from pajamas into comfy sweatpants, especially when no one behind the camera can see your cozy bottoms. But we promise you, even if no one but you is home, you’ll start the day off feeling a lot better if you’ve taken a few minutes to pick out a nice outfit. Not only will this be good for your well-being, but it will also get you back into the right work routine. Then, when you swap your work clothes for something casual in the evening, you can officially end your work day and feel more relaxed.

2. Goodbye distractions

The laundry pile is calling, the dishwasher is beeping and you’d like to vacuum right away when you see a few crumbs on the ground. We have all been there! When you’re at home, it’s easy to get distracted by your household and other small everyday tasks. But wait – working from home means you have to hold yourself accountable and stay productive. To manage all this, try setting aside blocks of time where you consciously do something for the household. Also, it can help to write down what distracts you for a week and then tackle those things. Another deciding factor is your work location, but we’ll get to that in the next paragraph.

3. Where to put all the work stuff?

The ideal solution for a perfect home office, would be to have an extra room that can be used for work. Of course, this isn’t possible for everyone, so we recommend setting up at least a small corner that can be used as a workspace and doesn’t have to be constantly moved aside. If you prefer a little variety, you can also switch between different places and set up a small and light desk which can be moved around easily. Also, don’t underestimate a comfortable chair and good light – your eyes and back will thank you later!

4. Blue light filters to prevent tired eyes and headaches

Speaking of eyes – if you work a lot in front of a screen, you will notice that your eyes get irritated and tired after a long day in front of the laptop. Our eyes are exposed to daily radiation, the so-called high-energy blue light that many electronic devices such as laptops, smartphones or tablets transmit. To solve this problem, we have developed our glasses with proven blue light filter technology. Your eyes will be protected from this radiation through our special lenses that filter out blue light and UV rays. This process relieves the strain on our eyes and makes us feel fitter and more alert. Perfectly in line with this we are releasing six new pairs of glasses on May 22 to help to focus on your work and keep an eye on your home office routine. Maybe you’ll find your new fashion accessory with practical benefits in our assortment of glasses – after all, you don’t need to have poor eyesight to create a cool look with glasses.

Ultimately, what matters most is that you feel comfortable and can work well. Some people tick differently than others – try to find out for yourself what you need to create the ideal home office! Of course, we hope you can use our tips to make your time working from home a little more productive!

We all know that our earth urgently needs help and that we are facing massive environmental problems. We as a company also have a great responsibility in this respect and must therefore choose the right actions. It is not our intention to say we are perfect, but we are constantly working to make the greatest possible progress in economic, ecological and social terms. That is why we want to take you on a journey today: from the production of our products to the delivery to your home, we want to make the steps transparent and show you how we try to make a positive contribution.

Where Everything Began – The Idea

As early as the product design stage, we attach great importance to sustainability. We believe well thought-out designs and high-quality materials should not only offer you a high degree of functionality, but also be so resilient that our products will accompany you on your adventures for a long time.

The Choice of Materials – How do we use our resources?

Let’s get to probably the most important and most interesting point for you: our materials. Since the quality of our products and our environment, with its limited resources, play a major role for us, we select our raw materials according to strict criteria.

On the one hand, our backpacks are made of polyurethane (PU), which you might also know as “Vegan Tech Material”. In contrast to the plastic polyvinyl chloride, PU does not contain chemical softeners, is durable and even water-repellent.

We have also switched to recycled polyester (rPET), as this means no new resources and about 59% less energy is needed in production – and all this for the same quality. We can obtain this raw material from cleaned PET bottles or even your old clothes. Only two of our backpack models, the Lund “Olive Green” and “All Black,” contain a small amount of tarpaulin and canvas, for which we are currently looking for sustainable alternatives.

For the majority of our sunglasses, prescription and computer glasses we use acetate – the bioplastic made of cellulose which has a lot to offer. Not only does it belong to the renewable and recyclable raw materials, but it is also very light and flexible to adapt to your needs. In comparison, the metal in our glasses does not cut so well, which we are of course completely aware of. However, we unfortunately had to realize that we have not yet found a comparable material with the light, robust and heat-resistant properties of metal that is even remotely as durable. So there is definitely room for improvement here.

So, you see all in all, our products are not only durable, but also our materials are of the highest quality!

The First Stop – Our Production Site

The majority of our products are manufactured in Shenzhen near Hong Kong. Now some of you might think: “Hm, China? Is that so sustainable,” because of the negatively connotated reputation of which “Made in China” unfortunately precedes the products. But we can answer “YES” with a clear conscience. Shenzhen is one of the most progressive and innovative cities when it comes to sustainability. Many young and creative people work there to produce high-quality products while adhering to ethical and moral standards. And we have even set up our own glazing facility for our prescription glasses in our adopted city of Cologne. Here we can quickly and regionally adjust your prescription glasses for you at any time.

But Wait – What are the working conditions in production?

Of course, in production it is important to ensure that everything on site is in order. That’s why employees from our product design and purchasing teams travel to Shenzhen on a regular basis to ensure that everything is running smoothly. In addition, external organizations carry out so-called ethical audits for us. These are production visits during which the areas of hygiene, safety, health, waste management, child labor, salaries, working atmosphere and working hours are reviewed and checked whether all standards are adhered to. This way we can promise you a safe production despite the distance of our production site.

We are also improving our recycling and disposal processes of leftover material so that we can help to produce less waste.

From China to Your Home – The Transport

Our production site in Asia naturally entails long transport distances, which is a major environmental burden. In 2019 we have managed to carry 90% of the transport by train. However, due to the unpredictable demand for some products, we unfortunately had to transport parts by plane, and this is where we see our potential for improvement in the future, as transport by train emits 40% less CO2. As far as packaging is concerned, we work according to the motto ‘Refuse and Reduce’. To reduce unnecessary packaging, we have gotten rid of using plastic bags and switched to a reusable cotton bag. In the future we plan to protect our glasses with a glasses cleaning cloth instead of plastic.

The last step in our transport chain is the delivery to your home. Here we rely on collective storage and transport service providers to make the delivery as efficient as possible. The majority of our shipments are climate-neutrally shipped by DHL GoGreen, which compensates the CO2 emission of the shipment by donations to a climate organization. In addition, you may have asked yourself why returns have to be registered with us first and why you should cover the return costs. At first glance, this sounds like a complicated and costly process. However, we would like to raise the awareness of delivery routes and thus minimize the return routes. In addition, we save a lot of paper by not including the return label in every single package, because it produces unnecessary waste if not used. In the long term, we are striving to find a solution by opening our own stores to further minimize and simplify returns and delivery routes.

We hope that our blog post has provided you with a little more transparency. For the future, we have set ourselves some goals in terms of sustainability and look forward to it positively and hopefully influencing our business. And we believe that together we can make a difference and hope that you will join us!

We have collected great tips that can help you find the right style for your face!

It’s a match – fundamentals for finding the perfect pair of glasses

As already established, when looking for a pair of glasses, you have to make sure that the shape fits to your face. With so many different styles out there it is challenging to find the best suiting pair of glasses for your face. Even though every face is unique, there are basically four different shapes to go by. Therefore, we distinguish between oval, angular, round and heart shaped faces. To discover what shape best describes your face; we have listed characteristics of each shape and found compatible glasses from our collection to go with them. So let’s find your new eyecatcher!

Oval face – Every style is possible

Is your face rather longer than wider? And are your cheeks the widest part of your face? Then you have an oval shaped face and are one of the lucky people that are able to wear any style of glasses. You can rock any shape, no matter if it’s cat-eye glasses, round pilot ones or if they have rectangular lenses. You can simply try on any style while always looking fabulous; so take advantage of your face that was made to wear glasses by adding the perfect eyewear accessory to your outfits.

Our sunglasses recommendation: any pair from Amsterdam to Valencia – there is no limit to your sunglass collection! Our blue light filter glasses recommendation: from Belleville to Williamsburg – the decision is yours!

Heart shaped face – Cupid’s favorite

When you look in the mirror and can make out a heart on your face then you might not only be hit by cupid’s arrow but also have a heart shaped face that indicates a wider forehead, distinctive cheekbones and a small chin. So when it comes to choosing glasses you have to be careful that you don’t make your forehead stand out and instead find a pair that makes your chin less pointy. We therefore recommend choosing round or oval glasses to give the face a gentle touch that compensate for the chin and forehead. With this little tip, we are sure you will find the right glasses that will make your heart skip a beat.

Angular face – the specialist for edges

Are your forehead, cheeks and jaw around the same size? Then you belong to the people with an angular shaped face. To not lose your facial features you should get round glasses that put emphasis on your features while also adding a little bit of delicacy. In addition, cat-eye and the so-called pilot glasses also work well with your face – we love an edgy look.

Round face – soft and gentle features

Round faces are often characterized as the face that has gentle features. Through the round chin and an even balance between the width and length of the face; people with round faces generally fit rectangular glasses or uniquely shaped ones. Those wider frames add a balance to your soft and gentle features by making it appear longer.

And for those of you, who want to learn more interesting tips and tricks on how to pimp your Instagram story, we have summarized the ultimate design ideas in this Instagram-Story-Guide.

Let’s start simple: Most of you should already be familiar with the text tool. It hides behind the “Aa” symbol and not only lets you choose between different fonts and colors, but also the position of the text and its background. If this info doesn’t rock your boat then the following tips will allow you to reach your creative potential.

3D-Text and Shading   

With this easy tip you can create a shadow for your writing, giving your text a 3D effect. How to do this: Copy your text and then paste it in the same font. To get the 3D effect, just change the color of the copied text and position it a little bit behind the original text – very simple but at the same time very effective. Our tip: Try this effect using the “modern” font on Instagram as we think it works the best in that writing.

The Bead Chain Text

Childhood memory alert: Do you remember the stylish bracelets and necklaces with single letters on the square beads? They are currently experiencing a comeback as jewelry and even in your Instagram story they can be used as a great design. You can create this by using the “classic” font on Instagram and typing each letter by itself, adding a white background to it. Position the letter squares next to each other – for the classic retro look you should keep the letters in black. For those of you who like it colorful, you can also change the background color making it fit to your story tone.

Box and Bars

As mentioned before, Instagram lets you change the background of your text. You can use this feature to create boxes and bars by simply pressing the space key on your keyboard multiple times until the box has the desired size. Make sure you are using the font that has the background option, those are only “typewriter” and “strong”.The font “classic” only works when you type an extra dot. With this you can create various designs since you can also make the background on this font transparent.

Fairy Lights and Lines

Another creative application the text tool can be used for is the arrangement of lines and fairy lights for your Instagram story. To create the fairy lights, choose the font “neon” and add a row of dots. For the lines we recommend to use fonts like “classic”, “typewriter” or “strong” and then add a row of underlines “_”.
