If you've got a 3D TV, you'll need to take care of the glasses to prevent damage and keep them working well – and this guide will show you how.
3D TVs come with either 'passive' or 'active' 3D glasses. Passive glasses normally come with LG TVs, and active glasses tend to come with Sony TVs and older Samsung models.
Passive glasses work by splitting the image in half: one half for each eye. These types of glasses are cheap and easy to make, and will normally only cost £5 or £10. The lenses are a soft plastic, and are pretty similar to the ones you'd get at the cinema.
Active glasses contain a lot of moving parts and electronics that rapidly change the lenses while the glasses are in use to create the 3D effect. All the extra bits in them make them more expensive: they normally cost £100 or more, so you need to take extra care with them.
Both types of 3D glasses will need regular care.
For passive glasses, it's not much different to a normal pair of reading glasses. Just wipe the lenses with a soft cloth, or use some glasses cleaner if they're a bit dirty. The lenses are a soft plastic, so they're unlikely to shatter – but they can still get damaged, so try to store them somewhere safe.
Active glasses need quite a bit more care. In addition to keeping them clean, you'll need to keep them charged, so they're always ready to go whenever you want to watch a 3D film. Sometimes, the TV manufacturer will also release a software or 'firmware' update for the glasses, to keep them running at their best. If you see any messages on your TV about updates, just follow the steps on screen.
The lenses are more brittle than those of passive glasses, so need to be cleaned very carefully: pressing too hard on them can damage them. Use a soft cloth and glasses cleaner to clean one side at a time, and try to avoid using any other type of cleaning product. You should also keep them somewhere safe, or get a case for them.
