Review on AoHeng 3D Clip on Glasses for Movies and Theater/Cinema Viewing | Passive 3D TV (Pack of 2) by Bobby Montoya

My child wears prescription glasses and hates going into 3D movies because the 3D glasses were uncomfortable and didn't fit over their regular glasses. This clip-on lens worked great and she really enjoyed her first exciting introduction to 3D. Each lens comes with its own slim hard case to keep it safe in your pocket or purse and fits regular or slim prescription frames. You may have trouble with more exotic styles. I've used them too and prefer them to the standard plastic blocks that movie theaters offer. They worked in both conventional 3D cinemas and 4D theme parks. The only problem is making sure you pick the right block. There are two formats in this pack and you need to match it with the theater you are going to. It's only difficult if you try to call ahead, the people who answer rarely know what format their devices are in. Until you know, bring both with you.
