Important questions and answers about 3D glasses
What are the functions of 3D glasses?
First of all it is important to master spatial vision. Essentially, this requires control of the eye muscles, which function without restriction. It is also important that there is a nerve connection between the two eyes. Once the eyes are restricted, this leads to a lack of spatial vision. It is not unusual for people to lack this ability to see.
How do you create 3D images?
Although your own eyes are important for spatial vision, the images can also be viewed technically. For this purpose, the technology creates depth effects. This creates the illusion in the brain that there is a depth effect.
Which 3D glasses are available?
There are two types of 3D glasses. These are as follows:
Passive 3D glasses use the spatial impression created by varying the circular and linear filter. Active 3D glasses are powered by energy. Hence the term “active”. However, these glasses require a completely different, namely high frequency. However, this can lead to this situation. This can lead to epileptic seizures. Therefore these 3D glasses are not suitable for everyone.
Make a purchase decision: Which of these 3D glasses suits you best ?
As already mentioned, there are two types of 3D glasses. The choice of the most suitable one depends of course on how you want to use them. To make a quicker decision, it is important to know the advantages and disadvantages of both types of 3D glasses.
Passive 3D glasses
The following advantages can be mentioned for passive 3D glasses:
- Battery-free operation
- Easy to operate
- At an affordable price
However, there are some shortcomings that speak against passive 3D glasses. This is the case:
- Light lines could be visible
- Works best with expensive displays
Active 3D shutter glasses
As with passive 3D glasses, active shutter 3D glasses have the same advantages and disadvantages. These must be taken into account when deciding which glasses to wear.
Advantages of 3D glasses with active shutter
- Also possible with inexpensive screens
The disadvantages of 3D glasses with active shutter are
- requires a battery
- A fixed headrest must be used
purchase criteria: How can I compare different 3D glasses with each other?
If you want to choose 3D glasses , there are things you should consider comparing different 3D glasses . This will help you find the 3D glasses that suit you best. These criteria are as follows:
- brand & manufacturer
- 3D technology
- The use of
- supply of electricity
brand and manufacturer
Since it is not always possible to get good 3D glasses with the right 3D TV , it is important to have an overview of the manufacturers as well as the brands that produce 3D glasses . The manufacturers are as follows: Acer, BenQ, Samsung, LG, Toshiba, Philips, Sony, RealD, Epson, Grundig, Thomson, JVC, Loewe, NVIDIA, Panasonic, Sharp, Telefunken, Zeiss, HiShock
In order to be able to compare other 3D glasses with each other at this time, you should know what you want to use the 3D glasses for. So if you want to wear 3D glasses, you can buy passive 3D glasses. They must be compatible with the technology used in the cinema. If you want to watch a 3D movie at home with a projector, you should use active shutter glasses. This type of 3D technology is also used in most current 3D TVs.
If a person has epilepsy or children wear 3D glasses, you should be aware of these risks. These points should therefore be useful:
Epilepsy: Danger: can cause epileptic seizures; refers to: Active Form technique; Use: should only be used in combination with other people
Children: Danger: Eye damage may occur; Applies to: Both types of 3D glasses; Use: Up to 10 years, maximum 30 minutes Do not use before the age of 10 years
In order to take full advantage of the 3D glasses, it is advisable that the polarization is compatible with the correct display device. Circular polarization technology is used as standard. The polarization of the ruler can cause ghost images when the head is tilted. However, this polarization in no way reduces resolution.
With active shutter glasses you can also choose how the power supplies are used. Some work with button cells, others with a battery. Here the battery is charged by means of a USB cable. The USB cable can be found in almost every household. This is because most smartphones are charged with a USB cable.
Here you have to make sure that the frame rate of your 3D glasses matches the frame rate of the TV. There are 3D glasses that can be used for different frequencies. This means they are compatible with a number of devices. Ghosting may occur.
Knowledge about 3D glasses
Is it possible to make your own 3D glasses?
It is possible to make your own 3D glasses, but it requires a lot of effort. So it can be easier to buy glasses than to make them yourself. In the various instructions on the Internet you can find out exactly how to make these glasses.
Who invented 3D glasses?
Laurens Hammond invented 3-D glasses. He patented television in 1922. The LCD technology used today was patented by Lenny Lipton. Lenny Lipton is the owner of StereoGraphics.
Is 3D without glasses already planned ?
There are already televisions that have a built-in camera that can create a 3D effect. However, this technology is expensive and is rarely used in families.
Why do 3D glasses have to be powered?
Thanks to Active Shutter technology, the lenses are alternately opaque. However, this only works with liquid crystals. These in turn must be switched on for them to work. However, this is a very energy-efficient technology.
