"Flare 40" by Studio Douze Degrés,

Flare is a lighting collection developed by Douze Degrés as part of its research on optics. Inspired by maritime lighthouses, it transforms a simple flame into a luminous signal.

Using an optical lens, the candlelight is captured, amplified, and projected—turning a soft glow into a vibrant beam.

The story of Flare began with an exploration of the visual distortion created by the Fresnel lens. Experimented during a scenography project at 3,600 meters altitude, for a live show at the Sphinx Observatory for Cercle Music.

In a world where visual clarity is paramount, eyeglasses have undergone a remarkable evolution. Among the array of innovations, progressive lenses stand out as a sophisticated solution, revolutionizing the way we correct vision. Whether you’re new to the world of eyewear or seeking an upgrade, understanding progressive lenses is key to unlocking a seamless visual experience.

The Evolution of Vision Correction:

Gone are the days when bifocals or trifocals were the go-to options for addressing multiple vision needs. Enter progressive lenses, a groundbreaking advancement offering a seamless transition between various focal points without the visible lines characteristic of traditional lenses.

What are Progressive Lenses?

Progressive lenses, often referred to as multifocal lenses, are a type of eyeglass lens designed to accommodate multiple vision needs—correcting near, intermediate, and distance vision within a single lens. Unlike bifocals or trifocals, which have distinct segments for each prescription, progressive lenses feature a gradual transition of powers, offering a more natural and aesthetically pleasing visual experience.

How do They Work?

The beauty of progressive lenses lies in their design. They have three distinct zones:

Distance Vision: Located in the upper portion of the lens, this area corrects vision for activities like driving or watching TV.

Intermediate Vision: Positioned in the middle part, it assists with activities like computer work.

Near Vision: Placed at the bottom, this area aids in reading or other close-up tasks.

Advantages of Progressive Lenses

Seamless Transitions: Unlike bifocals or trifocals, progressive lenses offer a smooth transition between different focal points, eliminating abrupt changes that can hinder vision.

Cosmetic Appeal: Without visible lines, these lenses look more like single-vision lenses, enhancing the wearer’s appearance.

Adaptability: Progressive lenses adjust effortlessly to various distances, providing a more natural viewing experience.

Overcoming Challenges:

As with any innovation, progressive lenses come with a slight adjustment period. Some wearers may experience:

Adaptation Time: Getting used to the seamless transitions might take a few days as your eyes adjust to the new way of focusing.

Peripheral Distortion: Initial use might involve slight blurriness or distortion in the periphery, which typically resolves as you adapt to the lenses.

Finding the Right Fit:

Getting the best out of progressive lenses involves precise measurements and considerations:

Prescription Accuracy: Accurate measurements of your vision needs are crucial for optimal performance.

Proper Frame Selection: Consult with an optician to choose a frame that complements the lens design and your lifestyle.

Are They for Everyone?

While progressive lenses offer exceptional benefits, they might not be suitable for everyone. Individuals with specific visual needs or those requiring specialized occupational lenses might find alternatives more suitable.

Conclusion

Progressive lenses represent a pinnacle in the evolution of eyewear, offering unparalleled convenience, aesthetic appeal, and seamless functionality. Embracing this innovative solution opens a world of clear and natural vision, empowering wearers to see the world with clarity and comfort.

World’s Largest Optical Lens Shipped to SLAC

When the world’s newest telescope starts imaging the southern sky in 2023, it will take photos using optical assemblies designed by Lawrence Livermore National Laboratory (LLNL) researchers and built by Lab industrial partners.

A key feature of the camera’s optical assemblies for the Large Synoptic Survey Telescope (LSST), under construction in northern Chile, will be its three lenses, one of…

A group of researchers from the Australian National University (Canberra) and the University of Wisconsin (Madison) has discovered that a single molecular layer L of molybdenum disulfide (MoS2) has a giant optical path length (OPL); in comparison to another monolayer material, graphene, the OPL of MoS2 is about 10 times greater.

Although this may seem like an esoteric result, it has a very practical consequence for photonics: as the researchers have demonstrated, just a few monolayers of MoS2 can be used to create what the researchers call the “world’s thinnest optical lens” only 6.3 nm thick. With a diameter of about 20 μm, the concave MoS2 lens the researchers fabricated has a calculated focal length of −248 μm at a 535 nm wavelength.

For experimentation, the researchers transferred single- or few-layer molybdenum disulfide flakes onto a silicon wafer (under a microscope, regions of differing colors corresponded to layers of different thickness). To create the lens, they used a focused ion beam to mill a concave bowl shape, producing a continuous, curved OPL profile. The giant OPL arises from a corresponding giant elastic photon scattering efficiency.

The researchers discovered that the strength of the elastic interaction in the thin 2D MoS2 increases greatly with a growing refractive index as a result of the ultrathin-film geometry. For every layer thickness increase of 1 nm, the OPL increases by more than 50 nm. The researchers say that other high-index ultrathin-film transition-metal dichalcogenide 2D semiconductors (of which MoS2 is an example) are particularly well-suited for this approach.
