Accurate and Easy to Use
Amcon Dry Eye Test Strips are designed to be not only accurate but easy to use. No shaking is required since the strip is designed to hold only 1 µL of fluid. The same small amount of fluorescein is applied to the eye with each strip. DET proves to be very user-friendly.
Invented by an Optometrist
The Dry Eye Test was invented by Dr. Donald R. Korb, a Boston optometrist , who is internationally recognized for his invention of contact lens designs.
Dr. Korb's name is synonymous with two of these designs: the lid attachment method of fitting rigid lenses (the Korb technique) and the first membrane soft extended wear contact lens, the CSI lens. He is currently the President and Technical Director for Ocular Research of Boston (ORB), a company he founded in 1987, whose primary pursuit is the development of products for the treatment of dry eye and dry skin.
Dr. Korb has a long history of discoveries documented by 24 US patents in the areas of ocular diagnostic equipment, contact lens polymers, contact lens design, and ocular drugs and formulations.

In this module we have all the functions and data structures needed to describe the projection of a 3D scene space onto a 2D image plane.
In computer vision, we can map between the 3D world and a 2D image using projective geometry. The module implements the simplest camera model, the Pinhole Camera, which is the most basic model for general projective cameras from the finite cameras group.
The Pinhole Camera model is shown in the following figure:
Using this model, a scene view can be formed by projecting 3D points into the image plane using a perspective transformation.
- \(M'\) is a 3D point in space with coordinates \([X,Y,Z]^T\) expressed in a Euclidean coordinate system.
- \(m'\) is the projection of the 3D point \(M'\) onto the image plane with coordinates \([u,v]^T\) expressed in pixel units.
- \(K\) is the camera calibration matrix, also refered as the instrinsics parameters matrix.
- \(C\) is the principal point offset with coordinates \([u_0, v_0]^T\) at the origin in the image plane.
- \(fx, fy\) are the focal lengths expressed in pixel units.
The camera rotation and translation are expressed in terms of Euclidean coordinate frame, also known as the world coordinates system. This terms are usually expressed by the joint rotation-translation matrix \([R|t]\), or also called as the extrinsics parameters matrix. It is used to describe the camera pose around a static scene and translates the coordinates of a 3D point \((X,Y,Z)\) to a coordinate sytstem respect to the camera.

Light hits surfaces, is reflected, and bounces away. This organic solar cell lamp utilises and gathers the energy from light sources that would otherwise have bounced off into nothingness, in order to spread an atmospheric light when amber fades the sky.
I have created a lamp that paves the way for how we can incorporate a new generation of solar cells into our everyday objects. Together with solar cell researchers at Epishine, I have built a system for integrating organic thin-film solar cells into design products.
The system is made up of screens that protect the solar cells, these screens can be put together in many constellations. I have considered the solar cells as a material in themselves, and integrated them into my design as a central form element.
With this project, I want to participate in the pursuit of a more sustainable and circular society by taking responsibility as a designer through value-driven methods with a view to apply sustainable innovations to real products. I see an opportunity to show the design world how far we have progressed, and above all, in what direction we are heading.


Astronomers around the world received a spectacular Christmas present this year as the James Webb Space Telescope successfully blasted off and started its mission which will eventually provide humanity’s best look yet at the deepest reaches of space.
But for a team of scientists in Greater Victoria, the launch meant much more. It meant decades of work had paid off, and they will soon get one of the first chances to use the new cutting-edge technology.
The telescope is a joint project between NASA, the European Space Agency and the Canadian Space Agency, but much of the science work for two key pieces of the $10 billion spacecraft was done by Dr. Chris Willot and his colleagues at the Herzberg Astronomy and Astrophysics Research Centre in Saanich.
”It’s been very exciting, but it was really nervy watching the beginning part of the launch,” said Willot. “At every stage, things seemed to be going well, so it was a relief for sure. The really great thing about this launch was the cameras on the rocket, which they don’t usually do … we got to actually see the telescope leaving [the rocket] and then a couple minutes later, the solar panel opened and we got to see it all deployed. That was really exciting to me.”
Willot currently serves as the project scientist for Canada’s contribution to Webb, co-leading the team with principal investigator Dr. Rene Doyon with the Universite de Montreal.
The team provided expertise to the CSA, helping to guide the scientific goals of the telescope and designs of its fine guidance sensor, which allows the telescope to navigate, locate and lock-on to targets to observe, and the near-infrared imager and slitless spectrograph, one of four devices used to observe and study distant objects.
While Willot joined the Webb team in 2006, the Herzberg centre has been involved since the very early stages of the project 25 years ago.
In addition to helping to guide the design and objectives for Webb, Willot said he and his team will also maintain Canada’s archive of all data collected by the telescope, helping to ensure it is accessible to scientists around the world, just as they have been doing for the Hubble Space Telescope since its launch in 1990.
But it’s the potential for future research once the telescope becomes operational in the summer that excites Willot the most, and scientists at the Herzberg centre will be among the first to use the telescope.
“My own research area is in the very early universe, looking for the first galaxies,” he said. “I’m leading one of the two large Canadian projects … we know that galaxies early in the universe are quite different from the galaxies we see today, so we are trying to trace the whole evolution of galaxies.”
Willot said Webb will be able to observe these distant objects in finer detail than previous space telescopes such as Hubble thanks to its larger size and its orbit further away from Earth’s surface.
“With a mission like this, we will undoubtedly discover a lot of new things in the first few years which will challenge our understanding of the universe.”

“A voyage to Europe in the summer of 1921 gave me the first opportunity of observing the wonderful blue opalescence of the Mediterranean Sea.”– Prof. C V Raman, Nobel Prize in Physics, 1930 (the first non-white, Indian or Asian to receive a Nobel Prize in any branch of Science)
This story begins with a voyage undertaken by C V Raman to the UK in the summer of 1921. Observing the Mediterranean while on board the ship, Raman wondered why the sea was so blue. The initial answer seemed to be that it was due to the scattering of light by water molecules, same as the explanation provided by Lord Rayleigh for why the sky is blue.
To test this explanation, Raman started experiments with his scientific collaborators and students at the Indian Association for the Cultivation of Science (IACS), Calcutta upon his return to India in September 1921. It soon became evident to them that the question was a fundamental scientific problem, and that the molecular scattering of light was a very general phenomenon which could be studied in gases and vapours, as also in liquids and solids.
For the next seven years, Raman and his associates continued to research this question, with many improvements to their scientific apparatus and techniques as they learnt more and more about the subject. In February 1928, Raman announced his findings to the press and sent his experimental data to Nature, where it was published in May 1928. The ‘Raman effect’ as it soon came to be called, was not only a phenomenon in itself, but one of the earliest proofs of the quantum nature of light. By 1929, the Raman effect was independently verified by other researchers, and in 1930 the Nobel followed.
What is the Raman effect?
The Raman effect is the inelastic scattering of light by matter, meaning there is an exchange of energy between a photon of light and a molecule that it strikes. The molecule either gains (usually) or loses energy, so the scattered light has an energy different (usually lower) from the incident light. This changes the frequency and therefore the colour of the scattered light. The change of colour can act as an ‘optical fingerprint’ for the molecule.
Why does all this matter?
This discovery of an optical fingerprint of a material forms the core intellectual property for the field of Raman spectroscopy, which is a non-destructive, in situ method to analyse materials and live tissue. It has many applications that directly and indirectly improve the quality of our lives, including:
Chemistry – to identify molecules and study chemical bonding and intramolecular bonds.
Solid-state physics – to characterise materials and measure temperature.
Biology and medicine – for tissue imaging, wounds characterization and many other uses.
Bio-pharmaceuticals – to identify active pharmaceutical ingredients (APIs) and their polymorphic forms, if any.
Investigation of art and heritage works.
Almost 100 years after the original research, Raman spectroscopy remains a vibrant area. Over the years, over 25 variants of Raman spectroscopy have been developed, with new applications being found all the time. The global market for Raman spectroscopy is estimated to be $1.8 billion in 2021, with numerous companies all over the world making a range of products for the above applications.
The original research and intellectual property have been continuously expanded and improved upon by generations of researchers, engineers and entrepreneurs to create an entire industry. And it all began with one man’s curiosity about why the sea is blue.
In my upcoming course, Products, IP and Entrepreneurship, we will be exploring this journey of an idea, through its many stages of nurturing and support, the many challenges it faces along the way, to its final destination as a product and maybe an industry.

The FEI Titan Krios G2 300kV Cryo-Transmission Electron Microscope is the premier cryo-TEM that is available for both single particle averaging and 3D tomography of vitrified samples. Equipped with a high-brightness field emission gun (X-FEG) and a high-stability 300kV high-tension (HT) generator, the system easily facilitates the high-resolution, sub-nanometer scale imaging of frozen biological specimens. The electron optical column is equipped with ConstantPower™ lenses, which have optimized magnetic circuitry designed to reduce cross talk and keep beam hysteresis to a minimum. This platform is also equipped with an image corrector that removes the increased spherical aberration present due to the larger pole-piece gap of the C-TWIN objective lens, which is required to accommodate large angle specimen tilts in tomographic data acquisition. In addition, the system is equipped with a unique, one-of-a-kind cryogenically cooled sample handling and auto-loading system. The Titan Krios G2 platform has been configured with two detection cameras, a scintillated CMOS camera (FEI Ceta), which will be used for regular TEM/STEM imaging and diffraction applications and an energy-filtered Direct Electron Detection camera (Gatan K2 Summit on a GIF energy filter) for the low dose imaging of frozen biological specimens. In addition, the platform is equipped with two other capabilities, phase contrast imaging and STEM imaging. The phase contrast system almost entirely removes the necessity to acquire images of low contrast objects under beam defocus conditions. Finally, the STEM imaging functionality is essential in high-resolution studies of cellular macromolecules in situ.
- Sample Auto-loading System - allows twelve independent samples to be loaded into a cassette, which can be transferred into the auto-loading system for delivery into the Titan Krios for imaging. The auto-loader is maintained at liquid nitrogen temperatures to protect the samples from any environmental factors, and each individual sample holder (AutoGrid) is robust and protects the sample against deformation and / or damage.
- Ceta CMOS camera - The Ceta is a 16 Megapixel digital camera designed specifically for regular TEM/STEM imaging. The large field of view and small pixel size (a characteristic of CMOS sensors) allows a fast read-out for dynamic experiments and is capable, of recording full-frame 4k x 4k images at 30 fps and a reduced field of 512 x 512 at > 250 fps. The camera can also easily switch between this fast mode and high-resolution mode with ease.
- Gatan K2 Summit Direct Electron Detector with GIF Energy Filter - The combined Gatan K2 Summit Direct Electron Detection camera and GIF energy filter – the “BioQuantum 967” allows for the direct detection of electrons at high sensitivity. In addition, the presence of the GIF energy filter allows the preferential detection of zero-loss electrons, thus serving as an additional mechanism to enhance the contrast of unstained, vitrified biological specimens.
- Cs Aberation Corrector - The C-TWIN objective lens with its larger pole-piece gap is essential for high tilt angle tomographic acquisitions. Its symmetric design allows for the changing of the accelerating voltage without adjusting the stage z-position. Additionally, it ensures that there is no performance compromise, or any re-alignment between TEM and STEM imaging modes. However, whilst important for tomography, the larger pole-piece gap in the C-TWIN objective lens increases spherical aberration. The addition of an image corrector removes this added spherical aberration (Cs) thus restoring the TEM/STEM resolution to that of a Titan microscope platform with a smaller pole-piece separation.
- Volta Phase Contrast System - A major issue in the imaging of unstained, vitrified samples is the lack of electron density, and thus contrast in the acquired images. A new, and cutting-edge approach that almost entirely removes the need for the addition of beam defocus is phase contrast imaging. By separating the phases of elastically and inelastically scattered electrons that pass through the sample by 90o, the in-focus contrast in the imaging plane can be drastically improved, which is beneficial in the imaging of weak phase objects, such as vitrified biological specimens.
- STEM detector - The ability to scan the electron beam whilst acquiring the transmitted electron signal, a so-called “STEM” image is essential in high-resolution studies of cellular macromolecules. The incorporation of STEM functionality onto the Titan Krios G2 platform increases its versatility without compromising any of the other imaging modes of the microscope (TEM, EFTEM etc).

Why Is The Sky Blue
“Because that blue sky that we all see is neither sky nor blue. What a shame that such beauty is not real!” These beautiful verses by Lupercio de Argensola are usually quoted as an example of the baroque disappointment for nature’s makeups. It was certainly during the 17th century when the man discovered with astonishment the reason for the color of the sky, that up to then had been believed to be compact and immutable.
The color theory developed by Newton explains that white light is formed by the combination of all the colors of the rainbow.
When we see an object of one color, it is because it reflects a certain wavelength and absorbs the rest, or which is the same thing, it reflects that color while absorbing the others.
At one end of the visible spectrum is red, whose wavelength is longer and therefore the lower frequency; because of this we call waves with a lower frequency “infrared”.
At the other end, violet, whose wavelength is shorter and therefore the highest frequency; therefore we call wavelengths with a higher frequency “ultraviolet”. But the sky, besides light composition, owes its color to another important factor: the atmosphere.
In effect, the light of the sun has to cross the atmosphere in order to reach us, and during that journey it looks altered. Minute particles of dust and water suspended in the air are smaller than the wavelengths of visible light, they do not have enough wave size to repel, but to divert slightly from its original path.
This is known as “dispersion”. And since the wavelengths on the blue end of the spectrum are shorter, they are dispersed to a greater degree than the rest of the colors, and this gives our sky its blue color.
To be exact, we need to add a third factor to determine why we see the sky as blue, and that is our own physiology. It happens so that, being consistent with what we have just said, the sky should be violet wavelengths as this color is still lower than in the blue.
If we see it violet is because our eyes capture the color in their own way, since they have cells sensible to only trhee colors: red, green and blue, and we perceive the rest of the colors by combination, that is, because they excite several of these three kinds of cells at the same time.
Therefore, as our sight is more sensible to the colour blue than to violet, it is that colour we observe when gazing at the sky.

Magnetic Clip-On glasses are a boon for people with similar issues. These magnetic clip-ons are cosmetic for your glasses and can be customized to your mood. Today, we are going to tell you the five advantages of having magnetic clip-on glasses.
Why Choose Magnetic Clip-On Glasses?
As mentioned, many people want to wear different glasses that compliment different occasions, but hoarding a large number of glasses is not the ideal solution. Magnetic clip-on glasses are detachable frames that connect to your glasses through magnets.
These robust magnets firmly hold the frame in its place and can be easily swapped out for a different frame. This feature can work well with sunglasses as well as prescription-based eyewear.
1. Lens Leisure
The adaptability of magnetic clip-on glasses is one of its main features. Many people need prescription eyeglasses to correct vision problems but still desire the benefits of sunglasses.
Magnetic clip-on frames solve this problem. These frames can securely retain prescription lenses while also allowing you to put an appealing shade on top when needed effortlessly.
This dual capability enables users to adjust to changing lighting situations and activities without changing glasses.
Furthermore, the clip-on lenses are frequently made of polarized polycarbonate glass, which provides UV protection. These lenses are available in polarization levels ranging from UV 100 to UV 400, providing complete eye protection.
Normal glasses go through occasional wear and tear and sometimes come apart in case of an accident. These shortcomings can prove harmful and cause serious damage.
Because they are composed of military-grade plastic like Trivex, that are used to develop shatterproof windshields. These frames and lenses are durable even under harsh conditions and can withstand extreme temperature with ease.
3. Fashion Quotient
Magnetic clip-on glasses are the latest fashion trend among the fashion-conscious. Their existence can be linked back to the 90s. With the recent revival of 90s fashion, clip-on glasses have made their comeback in the mainstream media.
Many celebrities and public figures have been spotted wearing nostalgic clip-on glasses. The effortless ability of these spectacles to smoothly blend in any outfit while maintaining their unique voice has skyrocketed their sales.
To meet this need, various firms provide a variety of materials for the construction of these frameworks.
From rich gold and silver embellishments to the futuristic appeal of aluminum and even denim injected with epoxy, these materials lend a touch of personality to your eyewear.
More importantly, these design and material innovations do not jeopardize the frames’ longevity, making them a functional but trendy alternative for anyone looking to express their individual style.
Because of their growing demand, magnetic clip-on glasses are readily available in the market. Many big firms retail clip-on glasses in their outlets and you can even browse their web portal for online shopping.
The worldwide eyewear market revenue has been projected to reach $141.5 billion by the end of 2023. This boom in sales has projected the global eyewear market to grow by 8.5% from 2023-2030.
5. Certified Safe
Initially, concerns arose regarding the safety of wearing magnetic clip-on glasses, particularly in relation to vision. However, extensive scientific research has provided conclusive data, establishing the safety of magnetic clip-on glasses.
In a recent study by Korean Physical Society members Dong Hyuk Kim and Hyun Mee Lee, contrast sensitivity between regular sunglasses and clip-on sunglasses was analyzed. The study found that the contrast sensitivity of the clip-on sunglasses was lower than that of the ordinary sunglasses with only one lens.
The contrast sensitivity at high illumination was higher as compared to low illumination. The contrast sensitivity of the clip-on glasses was better for a narrower lens spacing. Additionally, no difference in contrast sensitivity between the four colors coated on the mirror lens was observed.
The results have proved clip-on glasses to be just as safe for vision as traditional eyeglasses. Wearers can enjoy peace of mind, knowing that their eye health and vision are not compromised by opting for magnetic clip-on glasses.
6. Savings Savvy
Magnetic clip-on glasses are not only a style statement but also a financially groovy option. By opting for a magnetic clip-on glass, you refrain from purchasing multiple sets of glasses to change your style.
These glasses double down to act as your typical eyeglasses and can be transformed into funky sunglasses effortlessly.
Having this dual functionality assures that you get better value for your money and cuts down on your eyewear expenditure.
Furthermore, magnetic clip-on glasses allow you to constantly upgrade your style statements and keep up with the changing fashion trends without additional expense. This functionality makes magnetic clip-on glasses a cost-effective and desirable option.
Call it a style statement, an ode to the past, or a reasonable financial choice, magnetic clip-on glasses have succeeded in creating their niche audience.
The flexibility and durability of these glasses set them apart from their counterparts.


Boston Dynamics has so far refused to allow its robot dogs to be used as weapons. The weapons manufacturer “Sword” has now developed a similar robot-like dog with a sniper rifle attached.
The new war machine was shown at the US military exhibition AUSA in Washington. The armed robot is able to fire precisely within a range of up to 1200 meters. The system called SPUR (Special Purpose Unmanned Rifle) is controlled remotely.
Thanks to its sensors, SPUR can be used both day and night. According to Sword, the equipment includes a thermal imaging camera, a 30‑x optical zoom, and a special ceramic coating that is supposed to offer camouflage options and protection against modern night vision systems.
