Are you tired of feeling like a fish out of water every time you walk into an optician’s shop? Do you feel overwhelmed by terms like “monofocal”, “bifocal” and “progressive” and aren’t sure what they mean? Choosing the right type of lens for your vision needs can mean the difference between having crystal clear vision or eyestrain. In this article, we’ll walk you through the main types of lenses for eyewear. Let’s see if we can’t give you some greater clarity.

We use sunglasses all the time to protect our eyes from the sun’s ultraviolet (UV) rays and improve our vision in bright conditions. All the same, we may not know how they are made or what materials they’re composed of. However, the choice of lens material is crucial in determining their safety, visual effectiveness, comfort level and, last but not least, their resistance to wear and tear and general durability over time.

In this article, we’ll take a closer look at some of the main materials used to make sunglasses lenses, analyzing the advantages and disadvantages of each solution.

It would be wrong to say that the most expensive lens will definitely be the best lens for you. To summarize, in order to choose the right progressive lens, you need to consider the following factors: - PRODUCTION QUALITY OF THE PROGRESSIVE LENS (e.g. top-of-the-line, mid-range, or standard) - CORRECTIVE POWER and THICKNESS - COATINGS APPLIED

Your eyes express. Your lenses reveal. Tell your story with Divel! Divel presents a new campaign for MIDO 2023.

The campaign is inspired by a well-known Italian expression, “gli occhi parlano” (lit. “eyes speak”).

Summer is almost here! So get ready to accessorize with your favorite pair of sunglasses. Protecting your eyes against UV rays is important. Why not do it with some super trendy lenses? With Divel Italia can you have sunglasses with graduated lenses in any color you like!

In conjunction with Earth Day, Divel Italia has set a goal of conveying our commitment to the crucial issues of sustainability and the environment. At Divel Italia, in our continued pursuit of these efforts, we’ve recently developed a new material for our GREEN LINE collection: POLYCARBONATE Eco, an extremely lightweight, versatile product that is ideally suited to meeting your every need in terms of quality and environmental sustainability, because it is made using recycled material and mass balance.

Out of our Divel Sports lab come our Sport Single vision and Progressive lenses, a new line of graduated lenses designed for athletes. Available also in photochromic, polarized and mirrored versions, and with all types of coatings, to properly protect both the athlete and the eyewear itself. Lenses can be customized for functional purposes based on the needs of the athlete and of the sport. The color of a sports lens improves your vision by reducing glare and optimizing contrasts.

Our eyesight plays a fundamental role in how we see the world around us. With our eyes we look, we examine, we understand, we get excited, we love. Its importance must not be underestimated when it comes to sports. For outdoor sports, protecting our eyes from the sun’s harmful UV rays is essential. But we also need to protect our eyes from other external agents.

The material selected for a lens is fundamental, as it determines both comfort and clarity of vision.

Nowadays, there is widespread awareness of the dangers of direct exposure of our eyes to sunlight. This is why we often hear about glasses with UV protection in their lenses. When we are exposed to sunlight for extended periods of time, we risk damage to the eyes in the form of disorders such as cataracts, macular degeneration, pinguecula, keratoconjunctivitis and photokeratitis, which, in the most severe cases, can lead to temporary loss of vision. By definition, sunglasses are designed to protect us from harmful solar radiation, but it must be said that not all types of sunglasses are fitted with lenses that block 100% of UV radiation.

At Divel Italia, we have recently installed new equipment at our Milan production lab to further strengthen our production of prescription lenses.

What is L’una Aliena, you say? It’s our unique, personalized version of our top-of-the-line progressive lens, Aliena. What makes L’una Aliena different from other progressive lenses?

What is Digital Eye Strain?

Computer Vision Syndrome (CVS) is also known as Digital Eye Strain (DES), and both terms point to how prolonged exposure to the light emitted by the screens of our devices can be a major contributor to eye strain. There are many devices in the home or the office that can be responsible for DES — including phones, televisions, e-readers and, above all, desktop and notebook computers — if we spend too much time watching TV or playing video games.

The category of the lens depends on a value called Visible Light Transmission (VLT) or Tv (transmittance value). This is a measure of how much light the lens lets your eyes pass through and is expressed as a percentage.

Divel Italia has been nominated for the Silmo d’or 2023 with the Re-live lens!

RE-LIVE is an ecological lens created to improve our carbon footprint by generating fewer greenhouse gas emissions compared to not using renewable energy. RE-LIVE is our new, sustainable demo-lens made from 50% certified recycled materials obtained from mixed polyester waste.

As the name implies, corrective lenses, also known as “prescription” lenses, are used in eyewear in order to correct defects in the vision of the wearer.

Vision training? Fitness for the eyes? Our eyes are supported by a fairly complex set of muscles, so it is actually normal that these muscles need to be kept in shape. You may already have heard of certain exercises for the eyes, or orthoptic exercises, but you may not know exactly what we’re talking about unless you’ve already had a need for such exercises.

It’s often said that our eyes work a bit like a camera lens. Although digital imaging technology has, in many respects, surpassed the abilities of the human eye — such as in light sensitivity — corrective lenses are, in fact, based on how the human eye functions.

Bags under the eyes are very common and tend to worsen as we age. Aging, lack of sleep, improper hydration, genetic predisposition and lifestyle are just some of the major factors in this aesthetic issue, which can come to negatively impact a person's self-esteem.

There are many solutions to reduce or eliminate bags under our eyes, including good daily practices, natural home remedies, and surgical or other professional treatments. Let's see what they are.

One of the main concerns for anyone who wears glasses every day is that your corrective lenses will get scratched and ruined, which can be a significant expense if you have to pay to replace those lenses. Coatings have been developed for organic lenses to help increase the durability of eyewear.

Summer is on our doorstep, and the sun is shining for longer! It’s important to protect our eyes from sunlight. With photochromic corrective lenses, the lens adapts to changes in lighting conditions. But how do they work? When exposed to UV radiation, such as sunlight, photochromic corrective lenses undergo a reversible chemical reaction that causes them to darken. When no longer exposed to UV light, they gradually return to their initial state of transparency.

The high-energy blue light emitted by the screens of our computers, phones and other digital devices can, over time, be harmful to our eyes.

This is something we will all have heard by now, so many of us, especially those who spend long hours in front of a computer, will have already gone to our optician to buy glasses with blue-block lenses.

Using lenses designed to filter out this blue light, like our Blue Natural lenses, can offer a series of benefits for our eyes in terms of vision comfort, sleep quality and the overall health of our eyes, especially now that we are so frequently exposed to one screen or another. Here are just a few of the benefits:

Lens coatings serve to protect both the lenses and the person wearing them. By blocking certain types of light as they pass through the lens, we can enhance lenses in terms of look, vision, and overall quality.

Nowadays, people are generally aware of the danger of direct exposure of our skin to the sun's rays.

Light is typically understood as that part of the electromagnetic spectrum that's visible to the human eye. It's an electromagnetic wave emitted by the sun and filtered by the atmosphere before reaching the ground. The wavelengths of visible light, i.e. the distance between the peaks in a series of waves, ranges from 400 nm to 700 nm. In addition to visible light, there is invisible radiation at either end of the light spectrum beyond which the human eye is unable to see.

In addition to ultraviolet radiation, at wavelengths below 390 nm, infrared radiation, at wavelengths above 760 nm, and high-energy visible⁠ (HEV) light, also known colloquially as blue light, can also be dangerous for our eyes. HEV light is a blue-violet light at wavelengths between 400 nm and 500 nm, so it falls on the spectrum of light that the human eye can see.

Establishing healthy habits is essential to maintaining good vision health. Here are 10 tips to follow, even if you aren’t experiencing any deficiencies in vision.

In response to market demand, Divel Italia, in addition to reducing the environmental impact of our production site, now produces lenses and solar filters using increasing percentages of organic materials and environmentally sustainable by-products.

The material selected for a lens is fundamental, as it determines both comfort and clarity of vision.

To see clearly, you need the lenses of your glasses to be clean and in good condition at all times. This is why you should clean your eyewear daily using a soft cloth and water, cleanser, or other special cleaning solution or disinfectant recommended by your optician. Of course, the performance and durability of a lens also depends on the coatings that are applied by your optician of choice. So how do you choose the right coating for your lenses?

Put your glasses on. Take your glasses off… Who among us hasn’t found themselves doing this at least once? Or has seen someone else doing it? Sooner or later that day comes. The day on which, all of a sudden, you have a hard time reading text on your phone. Or the words in a book start playing tricks on you, or product labels seem like they’re way too small. Sure, you can move whatever you’re trying to read a bit farther from your face, but are your arms long enough? Not to mention that trying to ignore these symptoms can cause headaches and excessive eye strain. So the time has come to admit that you’re showing the first signs of presbyopia.

There are a few good habits we can adopt so that we don’t damage our lenses and to avoid worsening our vision. When our glasses are properly centered and straight, for example, we know we’re getting the best support for our vision and that our lenses and frames will last a long time.

Following research into lens waste conducted at the University of Palermo, designers Federica Ditta and Cristiano Pesca turned their attention to the various potential uses for this waste. They looked at both rejected lenses that failed to pass quality testing and excess material left over after shaping the lenses.

Why it’s important to see your optometrist regularly? You should get your eyes checked more frequently if you’re in an at-risk group. But what does that mean exactly? We’re not just talking about people who already have vision problems. There are a number of sub-categories of at-risk people that go beyond just those who already use corrective lenses.

There are various sports in which your vision plays a crucial role.

Take, for example, sports like billiards, **golf **and shooting sports. Here at Divel, we can provide corrective lenses for eyewear that give you the high levels of performance you need.

We’ve likely all been told from a young age that we should eat our carrots because they’re great for our eyes.

Our parents would try all the tricks they could think of to make us eat them. Cooked carrots on their own or together with potatoes, blended up in a pasta sauce, or pureed in a veggie soup. Here in Italy, about the only carrots some kids would eat was when they were chopped up with onion and celery and sauteed to make a Bolognese meat sauce, because then they would get lost in all the ground beef.
