Initially, traditional radiographs were mainly two-dimensional. These x-rays had a ton of limitations, one of which was the fact they could not provide depth or clarity of images. But with the advent of three-dimensional technology, medicine and dentistry fields have benefitted a great deal. Physicians now have access to more comprehensive images of the skull, oral cavity, neck and more. But health is not the only area where 3D technology has proven useful.
We also have an array of companies making 3D glasses, which are used in different areas. For instance, you can use these glasses to paint, create a 3D room, play video games and watch films. This article focusses on 3D active glasses. Read on to learn the best 3D active glasses.
What are the Best 3D Active Glasses?
To find the best 3D glasses, there are a couple of things you should look at. They should be reliable, provide a seamless operation, be durable and affordable.

How 3D Technology Works
Humans among other mammals have stereoscopic vision. What this means is that each of your eyes targets a specific object, and then the images of both objects are compacted together. This concept has been employed in television and movie theater screens, making videos from TV shows and movies be visible in a three-dimension. This way, the images seem real to the human eye.
For this artificial production of 3D images to be successful, screens have to be positioned in very precise angles so that each eye focusses on a different image. Therefore, the purpose of 3D glasses is to compact the split images, in the same manner as the human eye does when viewing objects in the real world. With 3D technology gaining so much popularity, many manufacturers have ventured into making consumer TV screens which employ this concept.
Available Types of 3D Glasses
Although there’s a wide range of 3D glasses, fitted with varying technologies, the two main types are: active 3D glasses and passive 3D glasses. No need to be scared by this technology jargon; it simply alludes to how the glasses interact with the wearer.
Active 3D Glasses
Currently, we only have one type of active 3D glasses and they function through a shutter system. These types of glasses use batteries but they can also be hardwired to the display system. The way active 3D glasses operate is by interacting with a display.
The shutter system serves to display a picture in one of the lens and then it darkens the opposite lens. This process happens so fast that an individual will never notice the lens switching back and forth. The darkening of one lens is facilitated by a liquid crystallization stratum, which acts in response to the voltage being applied. If you want to purchase 3D glasses for video gaming purposes, you should go for active 3D glasses because they are great at interacting with displays. For other activities, you might want to consider the passive types.
Passive 3D Glasses
Unlike active 3D glasses, the passive do not interact with any display. Passive 3D glasses operate in either one of these three mechanisms:
Polarized 3D glasses
This type of glasses utilize polarization technology when creating 3D images. The process entails projecting two images on a screen and then superimposing one on the other. One side of the glass enables you to see the image while the opposite side filters it out. Polarized 3D glasses make it possible for several users to view the same image at once. And the best part is, these glasses are cheap. In fact, these are the kind of glasses you’ll be given at a movie theater, if you wish to watch movies in 3D.
Interference filter systems
With an interference filter system, distinct wavelengths of green, blue or red are used for the left eye and right eye. The Dolby 3D glasses use a more specialized form of this technology referred to as spectral comb filtering. With this tech, different wavelengths are filtered out for each eye. This has the effect of generating two pictures, which are merged from the user’s perception; hence, forming one 3D image. Although these glasses do not require the pricey silver screens used with polarized glasses, they are still pricier than the former.
Color anaglyph systems
Passive 3D glasses that utilize this system have one side of glass displaying in red while the other displays in cyan blue. These very contrasting colors facilitate the filtering out of each other’s pictures. Unfortunately, these glasses do not generate crystal clear images. The reason for this is that they lack sufficient power to compensate the elusive filtering differences.
On the brighter side, 3D glasses that use color anaglyph systems are incredibly easy to manufacture and are used for magazine inserts.
Both the passive and active 3D glasses have their fair share of merits and demerits. For instance, passive 3D glasses tend to be lighter because they don’t include batteries or the on/off buttons.
Although bulky, active 3D glasses are better than passive since they’re able to display a 3D image resolution similar to the 2D image displayed on a screen. The only drawback with active 3D glasses is that they’re not flicker-free. The flickering arises from the fast opening and closing of the LCD shutters. Be sure to weigh the pros and cons of each to determine which type of 3D glasses meet your needs.
Choosing the Right Pair of Active 3D Glasses
If you’re planning to purchase a 3D television, you should know that some require you to use 3D glasses compatible with their technology. For instance, some 3D glasses are customized for projector televisions. Other 3D glasses are better suited for LCD or LED televisions. Thankfully, some 3D television models come with their own pair of 3D glasses. In case your television does not come with any attachments, it would be wise to inquire about the specific 3D glasses for TV.
One way of reducing eye strain when watching is by picking a pair of glasses that have a fast response time. Another aspect you’ll need to consider is the battery power. The majority of active 3D glasses utilize rechargeable batteries. But while some operate on independent batteries, others can work for a whopping 40 hours before requiring a recharge.
The last factors to consider when buying active 3D glasses are weight and level of comfort. Ideally, you should pick glasses that are lightweight since you’re likely to be wearing them for a long time. I bet you don’t want to spend a fortune on 3D glasses that end up being so heavy that they cause you a headache.
The Glasses Have to Match the TV or Video Projector
As stated previously, the 3D glasses designed for a particular brand of TV may not be compatible with another 3D TV or video projector. Put simply; if you have a Sony 3D-TV, your Sony 3D glasses may not work well with Samsung 3D-TVs. So, do not assume that you can always borrow your neighbor’s 3D active glasses to use with your 3D-TV.
3D Without Glasses is Possible but Not Common
Did you know that you can view 3D images on a television without using glasses? This is made possible by special displays known as AutoStereoscopic Displays. Unfortunately, these display are pricey and they require users to sit in very precise positions so they can have a good viewing of the images. It makes the AutoStereoscopic displays unsuitable for group viewing.
However, some progress has been made since we now have smartphones and gaming gadgets that feature the no-glasses 3D capability.
A majority of TV manufacturer seem to have fallen out of touch with 3D televisions. However, there’s still a small fan-base and tons of television sets with this capability. Besides, 3D viewing is a feature available on multiple video projectors. The one common thing between 3D televisions and video projectors is that you need a good pair of 3D active glasses to view their effects. If you’re not sure of where to start shopping, start by going through the 3D active glasses reviews highlighted above.
