How Do 3D Glasses Actually Work

3D Glasses Actually Work

While most people think that 3D movies are an invention of the last 40 or 50 years, it may surprise you to know that the first 3D movie came out in 1922. Since then, 3D technology has been in and out of the mainstream every few years. The biggest advance in 3D popularity was brought about due to James Cameron’s Avatar film. With the explosion of popularity in the 21st century, it looks like 3D technology is here to stay, with nearly every movie available to view in both digital and 3D in most theaters.

You may have seen a 3D in theaters and even watched 3D on your television at home, but do you know how 3D glasses work? There are a few different types of 3D glasses that work in tandem with projection to present you with an amazing visual display. Read on here to learn more from your friends at Rainbow Symphony!

How Do 3D Glasses Work

There are generally three types of 3D glasses including anaglyph, polarized, and shutter. Each uses different methods to bring flat images on your screen to life.

How Do Anaglyph 3D Glasses Work?

Anaglyph 3D Glasses Work

These are the most common types of 3D glasses and the iconic image many think about when they wonder how 3D glasses work. These glasses utilize special red / cyan lenses to interpret the image. These lenses produce the images you see by color filtering the layered image that you’re actually looking at. While one lens filters out all the red in an image, the other lense filters out the cyan, causing your brain to see the picture in 3D. The image you’re looking at is usually the same image projected from two different angles — or two entirely different superimposed images.

Anaglyph glasses come in several variations on the red / blue lens including:

How Do Polarized 3D Glasses Work?

Polarized 3D Glasses Work

How 3D glasses work when it comes to polarized lenses depends on deceiving your eyes just like anaglyph glasses do. How do polarized 3D glasses work, you ask? They restrict the light that enters your eyes, but instead of restricting the light by red and blue colors, they have a yellowish brown tint.

The image on the screen also has a role to play. In addition to the polarization on the glasses, the projected image is actually two images that are superimposed on the same screen through a orthogonal polarizing filter. Then the glasses, which have the same type of filter, allow each eye to see a the two individual images on the screen.

These glasses are actually the optimal choice for IMAX 3D movies and they’re the grey lens glasses you normally get at the theater today.

How Do Shutter 3D Glasses Work?

Shutter 3D Glasses Work

Shutter glasses are considered the most advanced type of 3D glasses available today. While the other two types of 3D glasses use something called passive 3D, shutter glasses utilize active 3D. They don’t use filtered image or color to create a three dimensional effect. Instead, shutter glasses work through LCD screen technology that darkens each lens, alternating the left and the right. The lens darkening happens so quickly that you don’t notice the effect unless you’re paying close attention.

Shutter glasses are usually battery powered, or even USB-supported, and are more expensive than traditional 3D glasses. The cost of these glasses make a huge difference to the image quality. You can get shutter glasses from Samsung, Panasonic, Sony, and more.

Why Do 3D Glasses Work?

3D Glasses Work

How 3D glasses work depends solely on how the eyes work and communicate with your brain. Human eyes have binocular vision that works best when you use both eyes simultaneously. Binocular vision gives you depth perception and allows you to tell which objects in your line of sight are closer or farther away.

Binocular vision relies on the distance between your eyes to present you with two different perspectives on the same thing. The distance between your eyes is generally about two inches apart, so the images each eye presents help to build a complete picture.

How Do 3D Glasses Work with Binocular Vision?

All types of 3D glasses work by making each eye see two different things. Whether it’s one eye seeing a red image and the other eye seeing a blue one or lenses that alternate darkening and lightening, your eyes seeing different things trick your brain into interpreting them in spectacular 3D.

Different Kinds of Rainbows

Different Types Of Rainbows

Whether you stand outside during every rain shower to spot rainbows or you just enjoy seeing them around, there are tons of different kinds of rainbows to spot and learn about. From multiple variations on the single arc rainbow to twinned rainbows and double arcs, check out what rainbows hold in store for you!

Singe Arc Rainbows

There are 12 different kinds of single arc rainbows that are decided based on the colors, strength of the bands, and supernumerary bows that appear, or don’t appear, in the arc. Here are the basics:

  • RAB-1 has all the colors visible, strong Alexander band, and supernumerary bows.
  • RAB-2 has all the colors visible, strong Alexander band, but no supernumerary bows.
  • RAB-3 has all the colors visible, weak Alexander band, and supernumerary bows.
  • RAB-4 has all the colors visible, weak Alexander band, but no supernumerary bows.
  • RAB-5 has no violet or no blue color.
  • RAB-6 has no green color.
  • RAB-7 has no violet and no blue color.
  • RAB-8 has no blue and no green color.
  • RAB-9 has only blue and red colors.
  • RAB-10 has only yellow and orangey red colors.
  • RAB-11 has only red colors.
  • RAB-12 is an unspecified other kind of rainbow.

You can create many of these rainbow reflections with Rainbow Symphony products like the Gem Series.

Double Rainbows

The double rainbow is another different kind of rainbow that you may see on a regular basis. Sometimes light is reflected off the same raindrop more than once to create a double rainbow. These are two separate arcs that appear together. The second rainbow will be an inverted rainbow reflection of the first — with the red on the inside and the blue on the outside. It’s also often much lighter than the first rainbow. On very rare occasions, you may see triple and quadruple rainbows.

Twinned Rainbows

Twinned rainbows may look like double rainbows at first, but if you look closer, they actually meet at the base. These are two arcs that split from the same spot. Scientists have yet to discover what causes twinned rainbows to appear!

Rainbows In Space

While different kinds of rainbows may not appear in space itself, as there is nothing substantial enough to reflect light, they may appear on other planets and moons. One of Saturn’s moons, Titan, has moisture and an atmosphere that is friendly to rainbow creation. It is believed by scientists that Titan is one place outside of Earth that rainbows can appear!

The Different Types of Eclipses

The Different Types Of Eclipses Infographics

Eclipses are a fascinating part of our universe and they are often exciting events around the world. Learn more about the different types of eclipses with Rainbow Symphony today!

  • Solar Eclipse*
    • A solar eclipse is when the sun is covered by the Moon. There are four types of solar eclipses.
    • Partial eclipse
      • In a partial eclipse, the Moon crosses the path of the sun, but does not completely block it out. The umbral shadow of the Moon misses the Earth, and only its penumbral shadow hits us. We end up seeing a sun that looks like a bite has been taken out of it.
    • Annular eclipse
      • An annular eclipse, from the word annulus (ring), occurs when the Moon completely covers the center of the sun, but it leaves the edges uncovered. There is a bright ring of the sun still visible in these cases.
    • Total Eclipse
      • When the Moon totally covers the sun, you get a total eclipse. Since the Moon is many times smaller than the sun, a total eclipse can only occur when its orbit falls very close to the Earth. In a total eclipse, you get to see the sun’s stunning corona.
    • Hybrid Eclipse
      • A relatively rare event, a hybrid eclipse is when one part of the Earth sees an annular eclipse, while another part of the Earth sees a total eclipse.
  • Lunar Eclipse
    • A lunar eclipse can only occur on a Full Moon when the Moon passes through a portion of Earth’s shadow. The next few lunar eclipses fall on Jan 31, 2018, July 27, 2018, and January 21, 2019.
      • Total Eclipse
        • When the entire Moon passes through Earth’s shadow you get a total lunar eclipse. The effects are especially striking, as often the Moon will look like it has taken on a red color.
      • Partial Eclipse
        • In a partial eclipse, a portion of the Moon passes through Earth’s umbral shadow. Visible to the naked eye, you’ll see that part of the Moon looks like it’s in total darkness.
      • Penumbral Eclipse
        • Very difficult to spot, a penumbral eclipse is when the Moon passes through Earth’s penumbral shadow.
  • Planetary Transits
    • While Venus and Mercury are the only planets close enough to Earth for us to see a planetary transit, when they cross the disk of the sun, it’s a special kind of eclipse.
      • Transits of Venus
        • Transits of Venus generally occur in pairs, but each the first of the pair is generally eight years before the second. More than a century could pass before another pair occurs.
      • Transits of Mercury
        • There are about 13 transits of Mercury that occur each century. The next time Mercury will cross the disk of the sun will be November 11, 2019. We won’t see another until 2032.

Rainbow Symphony loves exploring our universe and teaching others about its wonders. Next time a solar, lunar, or planetary eclipse occurs, track it with eclipse glasses and other accessories from our collection.

*Important note: Solar eclipses should not be viewed with the naked eye.
