3D Glasses For Projector - Buying Guide

<This is a guest post by a guest writer>

Which 3D Glasses for projector are the best? Which one will work efficiently with my projector? With many brands and models of 3D projector glasses on the market, you will definitely find these questions ringing in your head. Choosing a suitable model of 3D glasses is not an easy task. Nevertheless, in this 3D Glasses For projector – Buying Guide, I will disclose to you the vital tips required in order to make a wise choice.

 

How 3D Projector Glasses Work?

Just to refresh your memory, 3D projector glasses work by providing a separate image to each of your eyes. Your brain then combines the two images into a single image with 3-dimensional characteristics. The 3D projector has an internal decoder that picks up the 3D signal and displays the right and the left eye information on the screen in such a way that it appears like two overlapping images that look slightly out of focus. One image is intended to be seen by only the right eye, while the other is intended to be seen by the left eye. For you to view this image properly, you must wear 3D projector glasses that are specially designed to send the right and the left eye images properly to the right and the left eye respectively. The 3D process deceives your brain into perceiving a 3-Dimensional image. 

 

Tips for Buying 3D Glasses for Projector:

The most important tip when buying 3D projector glasses is knowing the type of 3D Projector Glasses to Choose. 3D projector glasses can be categorized into active and passive.

Active 3D Glasses: There are many active 3D projector glasses on the market. In order to choose the best, it is important to know whether you will require a 120 Hertz or a 144 Hertz. This is usually indicated somewhere in the specifics of your projector. It is therefore vital to confirm this before going out to buy.The 144 Hertz is better in comparison to the 120 Hertz because of its less flicker/faster refresh rate. Active 3D glasses can also be categorized into two main types. These are the Radio Frequency synchronization/Infrared Emitters (RF/IR) and the DLP-link. Both the IR/RF are perfectly synchronized and precise with the infrared emitters working just like your TV’s remote control and the Radio Frequency working like the remote keys of your car. However, the only limitation with infrared emitters is that they rely greatly on light and temporarily get out of sync if the emitter is blocked by an object. On the other hand, the Radio Frequency synchronization works perfectly under all conditions and is the most recommended. DLP-link glasses only work with DLP 3D projectors. It is advisable to look into the specifications of your projector before buying DLP-link glasses. 

Passive 3D Glasses: Passive 3D glasses work as a color filter or based on a polarization technique. Passive color filters do not rely on polarization. They are easily available and cheap. On the other hand, if you have two projectors with polarization filters, then you need to buy a polarized 3D glass. It is vital to know whether you are using linear polarizing filters or circular polarizing filters to ensure that the system works properly. Passive polarizing 3D glasses are readily available in different styles from numerous manufactures.

Passive 3D glasses are available at a readily affordable price . In addition, they do not have to be charged. On the other hand, batteries in active 3D glasses are currently performing better compared to their performance in the past. Active glasses with Radio frequency technology can last up to 70 hours of watching and require only three and half hours to recharge. To me this is a win win situation. If you follow all the tips outlined in this 3D Glasses For projector – buying guide, you can’t go wrong. Check out amazon for the latest prices.
