There is an understandable concern amongst those who wear prescription glasses that they will not be able to experience 3D with 3D glasses. Fortunately though, most 3D glasses do fit over the top of normal glasses quite easily, and the effect is not diminished. In fact some 3D glasses even come with a clip on device specifically made to fit onto the frames of normal glasses underneath.
Many 3D glasses have clips to help them to fit over normal glasses.
There are two different kinds of 3D glasses available, but they work in very different ways so it depends on the technique being used to project in 3D as to what kind of glasses you need. Either way though, they should be able to fit over corrective glasses.
If you are watching a 3D film at the cinema then you will be wearing polarising glasses. In this case the cinema will usually supply the glasses, sometimes for free and sometimes for a small fee. Most of these 3D glasses will fit over your ordinary glasses, however in some cases they do not. If you have found that to be the case, it might be a good idea to buy your own pair of 3D glasses to take with you, that way you will know that they will fit over your own glasses.
On the other hand, you may be watching a 3D programme on your 3D TV. In that case the glasses will be provided with the TV, and they will be active shutter glasses (almost certainly). They are the more expensive of the two types of glasses, but that is because there is a lot more technology involved in them – they require power for the LCD screens which flicker, helping to make the 3D effect. It is with these glasses that many of the manufacturers provide a special clip on portion specifically for people who wear glasses. However you should find that other sorts of glasses also fit over prescription glasses.
Do 3D Glasses Work Over Prescription Glasses?
It is all very well, you may be thinking, that the 3D glasses fit over prescription glasses, but do they actually work properly still? The answer to that is unequivocally, yes. Whichever type of 3D glasses you are using they will not be affected by corrective lenses. In the case of the polarising glasses, the lenses have already filtered out the two separate images (which is necessary to create the 3D effect) by the time it gets to your ordinary glasses. So it is just like watching a normal film, only each eye is seeing a slightly different one, combined in the brain to create one three dimensional film.
Similarly, with the active shutter 3D glasses, they are simply blacking out one of the lenses after another, doing nothing to the images being broadcast. Therefore it makes no difference whether you are wearing glasses underneath or not.
Whichever sort of 3D glasses you are using therefore, there should be no need to worry about them fitting over your glasses, and there is certainly no need to be concerned about them working properly.
