There are two main issues with this piece of garbage:
1. The clip doesn't work.
2. The color filtration is extremely poor, failing on the red in particular.
The moment you close the spring clip over a pair of glasses, the entire mechanism falls apart - there's nothing to keep the clip in place under tension. This alone isn't a fatal flaw (I used a twist-tie to secure the clip in place), but the lack of adequate color filtration is; it makes this product utterly unusable.
Also I bought these to clip onto corrective lenses, which is how they're made to work. The trouble is that the clips end just inside my field of vision and my brain gets distracted from the 3d illusion by focusing on the clips. While it can be ignored it and the poor effect overall eventually leads to eye strain.
When I do use them these days it's for short periods holding them up to my eyes rather than clipping them on.
AVOID THESE 3D GLASSES!!! The Amazon ad is false. They do not have red and cyan lenses. Instead, they have red and BLUE lenses. The Amazon ad states: "Optical quality, cast acrylic lenses tinted to EXACTING COLOR STANDARDS." (emphasis mine) Rubbish!!! These lenses are NOT tinted correctly. The blue lens has no hint of green in it. It is the old-style blue lens that old 3D systems used many years ago. It is NOT the cyan lens that modern anaglyphic 3D systems use today!!!
Why is this important? Answer: Modern anaglyphic 3D systems that use a red filter, switched away from blue and changed to cyan for the second filter many years ago. Cyan is equal parts green and blue---so it has a greenish blue appearance and most cyan lenses in 3D glasses are not as dark as the older blue lenses. The reason the switch was made from blue to cyan is because of the way color is divided between the two filtered lenses. One way to measure color is with the HSB model (hue, saturation and brightness). Hue is the chroma value and it is measured on a circle from zero to 360 degrees. Red is at the top at zero degrees and cyan is at the bottom at 180 degrees. Because red and cyan are at exact opposites on the color circle, they evenly divide all visible color between them, making cyan a better choice to separate the two frames of a 3D image when red is used for the first filter.Read more ›
Oh, and by the way, these render anaglyph 3-d excellently! Try 'em - you'll like 'em!
