What Are 3D Sunglasses?

The 3D glasses use the most advanced "time division method" today, which is achieved by the signal synchronized between the 3D glasses and the display. When the display outputs a left-eye image, the left eyeglasses are transparent and the right eye is opaque. When the display outputs a right-eye image, the right eyeglasses are transparent and the left eye is not transparent. I saw different game pictures to achieve the purpose of deceiving the eyes.

When the display outputs a right-eye image, the right eyeglasses are transparent and the left eye is not transparent. I saw different game pictures to achieve the purpose of deceiving the eyes.

With frequent switching in this way, each eye can obtain a slightly different image, which is calculated by the brain to generate a 3D stereo image. 3D glasses are designed with sophisticated optical components. Compared with passive glasses, they can achieve double resolution and a wide viewing angle for each eye.

Sun and eclipse glasses: Gray: It can completely absorb infrared and most of the ultraviolet rays, and will not change the original color of the scene.

Polarized glasses: made of polarizers for outdoor activities, fishing, mountain climbing, skiing, IMAX theater

3d glasses method one

Necessary materials: red paper, blue paper, ruler, cardboard, signature pen, scissors, lipstick glue. The colored paper was bought from a stationery store nearby. A large piece of paper was only 12 yuan. The cardboard was in the recycling bin and a thick cardboard was found.

Essential materials.

Step 1: Pick up your glasses and trace the shape on the cardboard with a pen. Remember to draw a thicker frame, which will be more durable; a larger nose bridge will better match the shape of the nose; the ear frame that supports the glasses (don't know how to say) is longer, if it is too long, you can cut it short, but There is no help in short words.

Everything is difficult at first, please draw your lines carefully.

Step 2: After cutting the shape of the glasses, cut the thick cardboard of the glasses frame with a blade.

Cardboard is difficult to cut.

Step 3: Use lipstick glue to stick the red colored paper to the left eye and blue to the right eye. Don't get it wrong. In addition, if the color is not deep enough, the effect of seeing three-dimensional will be poor, and you can paste two layers of colored paper.

If the color of paper is too light, you can stick two layers.

Remember the left eye is red and the right eye is blue. You can also use the waste paper box as a frame.

3d glasses method two

3D glasses production methods, sometimes suddenly want to experience the excitement brought by 3d special effects, make your own 3D stereo glasses. Save money is not difficult

Simple 3D stereo glasses production method: (Of course, the effect is almost worse than professional glasses)

Prepare materials:

1.Red cellophane

2.Green cellophane

3.Thick cardboard OR glasses <transparent>

Production method one:

Cut the cardboard into the shape of glasses, and dig two holes in the eye part.

Then stick the green and red cellophane on the left and right. <Left eye sticker red * Right eye sticker green>

Production method two glasses

Place red and green cellophane on the left and right. <Left eye sticker red * Right eye sticker green>

Mars Super 3D glasses diy method

Common color-separated 3D glasses are red-blue, red-green, etc. Taking red-blue glasses as an example, the left eye can only see the red image through the red lens.

The right eye can only see the blue image through the blue lens, and the different images seen by the two eyes overlap in the brain to show a three-dimensional effect. Below we take red and blue glasses as an example, DIY.

Materials:

Red plastic colored paper, blue plastic colored paper, ruler, cardboard, signature pen, scissors, double-sided tape.

Plastic colored paper can be found in general stationery stores. If you are lazy, you can find red and blue candy paper instead.

The first step: draw the glasses template, use the ready-made glasses as a control, and draw the shape on the thick cardboard with a signature pen; draw a thicker frame, which will be more durable; Make the temples longer. If they are too long, they can be cut short, but if they are too short, they will not be saved.

Step 2: Cut out the shape of the glasses. Cut out the middle of the frame with scissors.

Step 3: Use double-sided tape to paste the red plastic colored paper on the left eyeglass frame and the blue plastic colored paper on the right eyeglass frame. The left and right positions cannot be mistaken; The effect will be worse, you can fold the plastic colored paper in two layers and paste it.

If you do nt want to do paper-cutting by yourself, or you think the paper version of the 3D glasses is too ugly, you can find a flat-light glasses to "technical treatment": use the red marker on the left eyeglasses, and use the blue marker on the right glasses. The pen is painted in color. In order to achieve uniform color, it is best to paint both sides of the lens.

More lazily, you can find a transparent CD case, and use two-color markers to paint colors on the positions corresponding to the two eyes.

Friends wearing short-sighted or far-sighted glasses can also use your imagination to stick plastic colored paper or paint colors on the lenses.
