Light can be polarised by passing it through a polarising filter. A polarising filter has all its molecules aligned in the same direction. As a result, only waves with vibration aligned in the same direction can pass through.

In addition to raising funds for an invaluable cause, Illumination is devoted to discovering, attracting, mentoring, and directing over 100 diverse professional creators, emerging artists, and performing partners who are all committed to amplifying the Art of Light — illuminated sculpture, installation, experience, costume, objects, and effects. Illumination’s collaboration with the artist community makes for a particularly special event symbolic of hope and transformation.
The Clayco Foundation is determined to find a cure for Retinal Vasculopathy with Cerebral Leukoencephalopathy (RVCL). RVCL is a rare and fatal genetic condition affecting the central nervous system, causing the deterioration of small blood vessels in the brain and eyes of those affected. Most patients begin experiencing vision loss and strokes in their early 40s and have an average lifespan of eight years following their first symptoms. Rare disease affects nearly all of us. Thirty million people in the United States live with some form of the rare disease; that’s close to 1 in 10 people. We can make a difference by building on last year’s success.
Light is a transverse wave: the wave is S-shaped, with the curves of the S at right angles to the direction it travels. Essentially, the wave vibrates up and down as it travels forwards.
But 'up' and 'down' are not fixed directions. The vibrations could be vertical, horizontal, or at any angle in between. In fact, the waves that make up sunlight, for example, are evenly distributed across all angles.

Imagine holding a skipping rope so that it passes between the posts of a picket fence, and waving it up and down. The vertically aligned waves will be able to pass between the gap in the fence posts. But if you wave it from side to side, the waves will be blocked.
Since only a small selection of the waves can pass through a polarising filter, the overall intensity of the light is reduced. This is why sunglasses can be polarised: to reduce brightness and glare without compromising your vision.
In the past eight years, we have proudly raised $9.8 million for cutting-edge, leading research to cure RVCL. For information on how you can invest in our research, join our team, and save lives, please contact our team by completing the form or by emailing us.
Some animals can see in polarised light, including the fiddler crabs and mantis shrimp in David Attenborough's Life in Colour.

Illumination is a vibrant Halloween party where artistry and philanthropy unite. Set amidst a radiant spectacle of interactive installations and glowing processions, this event is more than just a celebration. It's a chance to support rare disease research, specifically RVCL, in a playground of light. Engage with illuminated characters, participate in fiery parades, and immerse yourself in the delightful luminosity. Your participation helps us shine a light on the path to discovery. Let's illuminate the night and the future of RVCL research together.
Light is also partially polarised when it bounces off a shiny surface. For example, the light that reflects off a horizontal surface, such as a puddle, is mostly horizontally polarised. Polarised sunglasses are usually vertically polarised to reduce the glare from puddles or wet roads.
