Holiday Specs holographic lenses transform any bright point of light into different magical images. When you put on these Holiday Spec glasses on your going to be surprised what you see. These are patented Holographic glasses that bend light and create holiday images from every bright light. Each set of glasses has a different holiday image from snowman, raindeer, candy cane, Gingerbread man and Santa’s face. 

The lenses used in Holiday Specs bend the light emanating from any light source to transform regular light into art.

When you look up close to through the diffraction glasses, you are looking through a piece of material called diffraction grating.
This grating is a piece of plastic that has small openings which is usually very narrow and closely spaced to each other.
When light passes through these openings, it bends by an amount dependent on the type of light. For example, red light bends more than yellow light.
When white light enters a diffraction grating, it separates into its fundamental colors. These colors are the same as the spectrum of colors you see in a rainbow.

They’re special glasses that, when you wear them, turn a typical Christmas lights into a magical images, creating beautiful shapes in the form of a image out of each light.

Light Diffraction lenses for anyone who was wondering how they work. Basically micro etchings in the plastic lenses cause light to diffract in the shape that is etch on those lenses. 

Understanding how this works isn't easy. It's an interesting property of nature that light going through those glasses diffracts into a Fourier transformed image. 

The fun thing about this is that it doesn't matter where the light moves through the glasses. The glasses will have many Fourier transformed reindeer on it all across the glass allowing the light to diffract. The result is as seen.

Here's a way to see the basic hologram effect. You know those clear CDROMS that they usually put on top of a new stack of CD-R or DVRs? Sometimes those aren't just clear plastic. They actually have the CD tracks, and they give rainbow colors. Hold one of those up to your eye and go look at a distant streetlight at night. You'll see two rainbow blotches hovering near the streetlight, one on each side. The CD is a diffraction grating, and those blotches are your basic hologram. They are holograms of one pixel! (And if you stacked hundreds of CDs on your eye, you could construct a snowflake image. That's essentially how a computer makes those. Each fine pattern of parallel lines on the plastic will create a pair of glowing pixels that float in space.)
