What Are Diffraction Glasses Used For?

You’d be surprised how many applications these all-purpose rainbow glasses have! Diffraction is part of everyday life and most people don’t even realize it. From science to entertainment, these bifocals are great for many purposes, including:

• Fireworks and Firework Shows
• Holiday and Christmas lights
• Festivals and carnivals
• Watching TV/ 3D Movies
• Visualizers on as itunes windows media player
• Projection mapping and 3d screens
• Light shows
• EDM Events
• Music Festivals
• Lasers
• Led Gloving and orbit light shows
• Enhancing any lightshows or performances

How Do They Work?

You may have been recently introduced to a revolutionary visual experience called . With its exciting effects, it’s taking the nation by storm. But what is diffraction really? Diffraction is defined as the process by which a beam of light waves is spread out as a result of passing through a narrow aperture or across an edge or “grating”.As the light passes through this grating, each

beam of light is split into its individual spectrum of colors turning white light into a full rainbow spectrum. This is the main principle behind what gives diffraction glasses their awesome visual sensation. White light will show the widest array of colors, whereas looking at a blue light for example will show its component colors. Check out what diffraction glasses really look like when viewing a single light source!

As you can see, just looking at a single light source creates a burst of colors. Now imagine looking at hundreds of holiday lights, fireworks, or lasers, and you can see why diffraction glasses have really become so popular.

The history of goes back far beyond over 300 years ago, when Sir Issac Newton observed a beam of sunlight pass through a glass prism. What he discovered is that light is made up of a spectrum ranging from 7 different visible colors. This is the exact same visible spectrum that you see when wearing diffraction glasses today! During this time a man by the name of Francesco Maria Grimaldi, also observed and characterized what would soon be known as light diffraction. Francesco is also known for coining the term “diffraction, ” from the Latin “diffringere, ” ‘to break into pieces.’ Fast forwarding through history, a scientist named James Gregory observed the first form of diffraction grating, by studying the light break up caused by bird feathers. Throughout the years, their observations were studied and molded into the theories and laws, which govern, light diffraction as we know it today.

Diffraction, in physics, is the spreading out of waves, such as those of water, sound, radio, or light, as they pass around an obstacle or go through an opening. A couple everyday examples are water waves spreading out as they move around an obstacle such as a projecting rock in a stream. These waves have been diffracted. Another more familiar form happens when a light hits the back of your favorite CD, casting a rainbow of colors, or simply the hologram on your credit card is the result of light grating. Light waves ordinarily will not bend around corners, but they will be diffracted when they pass through tiny openings. This is the key to providing an awesome and stimulating visual experience. When light strikes a grating (in our glasses this is the lens) which is marked with thousands of parallel lines, the light waves are caused to spread in such a way that they produce a spectrum, or rainbow, as pictured above! Even tiny water droplets can act as a grating to create a 3D prism of light diffraction.

Another cool fact about diffraction is that you can actually tell a plethora of different information based on the spectrum of colors it produces, when the light it emits, passes through a diffraction grating. For example, you can determine how hot the object is, how fast it’s moving, or what it’s made of. When looking at objects, such as distant stars, this kind of information can be very beneficial. Realistically though, you are most likely buying a pair of these glasses for entertainment purposes and could care less about the temperature of a star millions of light years away.

So what makes the best diffraction glasses? Well, it depends what you are looking for out of your glasses. Some people enjoy a softer effect to wear during the day and for long-term use. Whereas most people look for the most intense effect created by multiple lasers of grating materials or multiple lenses. If you are looking for Rave Glasses, we recommend an intense effect as found with our 3D Diffraction Glasses, or Matrix Glasses. Some even prefer customizable diffraction glasses or custom printed. Do keep in mind, the more diffraction you have, the less white light passes through the lens creating a more blurry view. The best diffraction glasses at the end of the day are judged on a personal perspective. Luckily, GloFX offers hundreds of dimensional eyewear options. You’re bound to find a pair of EDM glasses or rainbow glasses that suites you.
