There are two types of 3D TV. One is the active type and the other is passive 3D TV. The first one is 'shutter glasses' and the second is 'polarized glasses'. Shutter glasses have a kind of shutter that needs a rechargeable battery. The active glasses last over 100 hours on a single charge these days and are as light as some passive glasses.
Depending on the type of 3D television you have you will need one or other type of glasses.

No, there is no battery used in LG's 3D TV glasses as they have chosen to use passive glasses.
Battery free glasses for 3D are better if they are being used with passive 3D televisions. LG only have passive 3D television so the battery free glasses work with them. The other premium brands such as Samsung, Sony etc all use active 3D and their glasses are battery powered. The active glasses are far better for use with active televisions because the battery free glasses won't work with them. Previous criticisms of active glasses were weight and battery life. With the weight below one ounce and battery life of over 100 hours, neither of these are issues any more.
Yes, individuals with a pacemaker can generally use 3D rechargeable glasses, but it's important to consult with a healthcare professional first. Some 3D glasses may use magnetic fields or emit radio frequency waves, which could potentially interfere with pacemakers. Always check the specific model and follow any recommendations from your cardiologist to ensure safety.
Active glasses and passive glasses use very different technologies to separate the left and right eye images. To choose a 3D television based on the type of glasses is not a wise decision. Spend time to study both active and passive images. Experience a range of models and get a feel for the difference in the glasses. Make your choice based on which image is the best, which glasses are most comfortable and which 3D image looks the most realistic. Remember that active glasses are now as light as passive glasses so there is rarely an issue with heavy glasses now.
Spectacles and glasses are exactly the same in meaning but different in usage. The word spectacles is considered to be an old-fashioned and formal term for Americans but it is still used in British.
spectacles are glasses like you wear on your face. a microscope is a tool used to identify small objects
I definitely don't call them people who can't distinguish the difference between "were" and "wear."

Active 3D glasses are far better than passive glasses when used with an active 3D television. Similarly, passive 3D glasses work well with passive televisions. Active glasses have been criticized for their weight in the past. Later glasses are lighter than many passive glasses, have a battery life of over one hundred hours and are proving to be exceptionally reliable.
Sunglasses are designed to protect the eyes from the sun's harmful UV rays and bright light, while glasses are typically used for vision correction. Sunglasses have tinted lenses, while glasses may have clear lenses or prescription lenses.
