Hello, these are good quality goggles, however this 3D technology significantly reduces the brightness and color tone. Hence the interest to try other 3D technologies such as shutter glasses (15 at Amazon), which are mainly used for 3D TV (unfortunately little inter-compatibility), and restore a truly excellent image. There are also passive polarized 3D glasses (also 15 at Amazon) used especially in 3D cinemas, whose report is just as great if the source is very bright.
