Single Vision Designs

A single vision lens corrects the following:

	Near-sightedness: Faraway images appear blurred while close images are reasonably in focus; corrected with ‘minus’ power convex-lenses.

	Far-sightedness: Faraway images are reasonably in focus and close images appear blurred; corrected with ‘plus’ power concave lenses.

	Astigmatism: The eyes look in two different directions at right angles to each other; corrected with the application of a cylindrical power

	Presbyopia: Usually occurs for those people aged 40+.  They find it increasingly difficult to read, as the lens of the eye becomes less flexible and focusing on nearby objects becomes difficult. In the single vision category, reading glasses can be the solution.

Single Vision solutions from Hoya

Countless innovations have allowed the Single Vision design to be perfected. For instance, aspheric lenses (Nulux design) provide a thinner lens with a larger, distortion free field of vision, whilst double aspheric lenses (Nulux EP design) guarantee focused vision over their entire surface of the lens in all directions. Nulux Active is a brand new concept that provides extra support to enable you to work and play harder for longer.

Hoya Single Vision lenses are available in different lens designs:

	Nulux EP: calculated and produced according to the FreeForm principle, which allows each detail of the lens to be precisely determined to create a synergy between correction and natural sight.

	Nulux Active: provides support above and beyond a traditional single vision lens. It guarantees a more focused vision ion all directions and varaible distances and prevents tiredness, enabling you to work harder for longer.

	Nulux aspheric: the radius leading from the centre of the front surface to its edge becomes longer, and the radii form a purer focal point. This results in less deformation in the periphery of the lens

	Hilux spheric: features a single central radius on the front surface and, depending on the prescription, different radii on the back surface. ESSILOR
2010 25 March 2010 Essilor unveils the www.crizal.com website In order to present a strong, consistent image of the Crizal band and strengthen its identity among consumers, Essilor has launched the www.crizal.com website. Its purpose is to provide consumers with a simple, fun way of learning about all the benefits of Crizal anti-reflective lenses.

The new generation Varilux Physio lens featuring WAVE 2.0™ (Wavefront Advanced Vision Enhancement) technology represents a new phase in wavefront management. The Varilux Physio 2.0 is the first lens that takes into account all the different factors responsible for the variation in pupil size in order to deliver High Resolution Vision™ throughout the day, whatever the distance and light conditions. Varilux Physio 2.0 was introduced in Europe in January and the United States in February. For more information go to: www.varilux.com 2009 16 October 2009 New Varilux Website! To develop a unified image for the Varilux brand around the world, Essilor has launched the varilux.com website. Specifically dedicated to the Varilux brand, the site presents the entire product range as well as the brand’s history and values. Educational content on presbyopia is also provided and visitors can take an online eye test to determine which Varilux lens is best suited to their specific needs and lifestyle. Discover the new www.varilux.com website. 7 October 2009 Essilor Wins Two Silmo d’Or Awards Essilor won awards for two of its products at the 16th Silmo international optics show held on September 17. First, Essilor was recognized in the Low Vision category for its AFTER software. The application is designed to meet the needs of the visually impaired, who experience a decline in contrast sensitivity over time and have to wear selective filters on their lenses in order to continue perceiving objects at low contrast. Essilor’s AFTER software enables opticians to easily and quickly evaluate a patient’s ability to perceive objects at different contrast levels. In this way, filters can be tested and sold based on professional results and not merely on patient testimony as was the case in the past. In addition, Essilor was recognized in the Workshop Tool and Equipment category for Mr Blue™. This new digital system comprises a tracer-center-blocker that measures frames, detects the optical center of corrective lenses and blocks lenses for edging. It also has an integrated edger to shape lenses prior to mounting. 2 June 2009 "Bien vu, Varilux!" Exhibition Committed to an assertive policy of promoting its scientific and technological heritage, Essilor signed a partnership agreement in 2008 with France’s Conservatoire National des Arts et Métiers (CNAM). As part of the agreement, the Musée des Arts et Métiers will host a temporary exhibition called “Bien vu, Varilux®!” from June 9 to November 29. The exhibition will cover past, present and future solutions for correcting presbyopia.

CFnews, an online publication specialized in corporate finance, presents the award every year to a French company. In 2008, Essilor invested over €500 million to complete 27 acquisitions worldwide, including Satisloh, the world’s leading supplier of prescription laboratory equipment. Acquisitions in 2007 and 2008 added 5.1% to growth in 2008, leading to an overall increase in revenue of 9.7% at comparable exchange rates. Essilor is committed to pursuing acquisitions over the long term. Since 2003, it has acquired 95 companies, primarily in the prescription laboratory market. 12 February 2009 Essilor and Nikon joint research centre in Japan . Essilor : a strong identity The culture of the Essilor Group is founded on 4 main pillars : trust, the culture of the optical world, diversity and employee involvement. Trust in each person and in the company Essilor enjoys a strong corporate culture founded on individual initiative, which functions thanks to a policy of transparency in relationships between individuals. This transparency is the guarantor of sound decision-making. At all levels, each employee is thus encouraged to develop his or her role and activity. In the same vein, the group’s different subsidiaries enjoy a large degree of autonomy in their choices and operate in a decentralized management mode. Priority is given to our shared, collective ambition over individual interests. An acute understanding of the world of optics In a sector where confidence in each optician or optometrist is critical, Essilor is endeavoring to develop a relationship of trust, based on the long-term. All Essilor employees are asked to pay particular attention to the demands of each customer. Diversity as wealth Currently operating in nearly 100 countries, the Essilor Group continues to expand not only through internal growth but also by external acquisitions. Every year, the employees that join our Group enrich our culture by acting, in a sense, like new members of a club. Essilor has made a virtue of valorizing different cultures and ways of thinking. The employees are the first shareholders of the Essilor Group Since Essilor’s creation, the employee shareholding has acted as the stronghold of this culture, following the tradition of the craftmen’s co-operative that is at the origin of the Group. Colleagues have always been encouraged to take shares in the Group’s capital and today, out of the 30,000 Group employees, nearly one in 4 is an Essilor shareholder. The employee shareholding represents the Essilor Group’s most important shareholder and permits an original mode of governance, with employees being fully involved in the strategic decisions of the Group through Valoptec, the shareholder employees’ association. Employees vote on general policy options tabled by the management. Employee shareholding also favors the financial independence of Essilor, thus contributing to the sustainability of the Group and its culture.

The Eye Illutions

Impossible Objects Illusions

Our brain tries to do its best usually, however, there are instances when it fails to process correctly what the eye sees. The brain makes sense of shapes and symbols. It's trying to put them together like a jigsaw puzzle, formulating that which isn't there to that which is believable. 2D figure is subconscionsly interpreted as 3D object although such object can not exist.
The Penrose Triangle, also known as the tribar is one of the most well-known Impossible Figures. Try to trace a line in the triangle and you would have to trace it three times around the triangle before coming back to where you started. (by Roger Penrose)

---

The Penrose stairs is a variation on the Penrose triangle. You could climb the stairs forever and never get any higher. That is only possible in two dimensions. This endless staicase can be found also in the paintings of M. C. Escher or also in the movie Inception by Christopher Nolan. (by Roger Penrose)

---

This impossible object (blivet) is called "Devil's Fork" or "Three-Pronged Poiuyt" or "Schuster's Conundrum" (by D. H. Schuster)

---

This is one of classic optical illusions - it is called dancing elephant. Try to count the number of his legs (by Roger Shepard).

---

Given the wood do you think you could make this

---

Another impossible figure.

---

Is the blue wall in the block or on the block? Is it the back wall or the side wall? You can flip back and forth between the two valid interpretations (so-called multistable perception). This ambiguous line drawing called Necker Cube was discoverd in 19th century.

---

A realistic photo or just another undecidable figure?

---

Is this a complete cube or just 3 sides of it?

---

Try to arrange dice like this.

---

Another interesting building.

---

This corner house is a bit tricky. Question: Is the corner concave or convex? Use your palm to cover the upper half of the picture and the corner will be bulged out. However, if you cover the lower half, then it will seem as the inner corner. Amazing.

Word Illusions

If you can read the following picture, then you can shout ...

---

---

Can you read the below?

---

At first glance, what do you see? Could it be the word "liar" or is it something more. I would definitely give this one a second look!

---

This painting is called "Optical Illusion" - literally - you can read it (by John Langdon).

---

Victory or defeat? Both (by Veja Magazine).

---

Have you ever noticed a hidden arrow in the FedEx logo? It stands for speed and precision. Check the space between "E" and "x".

---

Try to say the color of the words, instead of actually reading them. You will find it surprisingly difficult. The right half of your brain is trying to say the colors, the left half is trying to say the word itself. This brain teaser is used by mountaineers to test if their concentration is ok. (by J. R. Stroop).
