Almost four in five people who buy a 3D TV regret it, according to a new study.

1,172 3D TV owners were asked by the study in the UK.

The study showed 79% of 3D TV owners responded to the question “Are you glad you purchased a 3D TV?” by saying “no – I regret doing so”.

When asked why they regretted it, the answers broke down as follows :
•There isn’t a wide range of 3D films and channels – 61%
•Had to purchase 3D extras (3D glasses, 3D source device, etc.) – 57%
•Causes symptoms of nausea, headaches and/or dizziness – 31%
•Dislike wearing glasses whilst watching 3D TV – 24%
•Unable to see 3D – 5%

What is 3d TV?

3D TV is a type of television technology that allows viewers to experience content in three dimensions, adding depth to the picture, making it appear as though the images are coming out of the screen. This effect is achieved by delivering separate images to each eye, which the brain combines to create the perception of depth, similar to how we see the world in real life.

There are several types of 3D TV technologies, including:

1. **Passive 3D**: Uses polarized glasses, similar to those used in 3D movie theaters. The TV displays two slightly different images that the glasses filter, sending one image to each eye.

2. **Active 3D**: Uses battery-powered glasses that rapidly shutter each lens in sync with the TV’s display, showing alternating images to each eye at a high frame rate. This method provides full-resolution images but can be more expensive and cause eye strain for some viewers.

3. **Glasses-Free 3D**: Also known as autostereoscopic 3D, this technology doesn’t require glasses. It uses special screens that direct different images to each eye, but it often requires viewers to be in a specific position to see the 3D effect properly.

3D TV gained popularity in the early 2010s, but its appeal waned due to high costs, limited content, and the inconvenience of wearing glasses. By the late 2010s, most manufacturers had stopped producing 3D TVs, and the technology became largely obsolete.
