3D GLASSES

Red/Cyan

Red Cyan 3D Glasses

Red Cyan 3D Anaglyph Glasses

Red-Cyan glasses are for viewing printed 3D anaglyphs. These range from film or cinema posters, magazines & newspaper specials to promotions on cereal packets or any other 3D printed material.

You may find that printed material has been split for red/blue or red/green glasses, it's quite common.  Check first before buying your glasses to view a particular image.

Red/Blue

Red Blue 3D Glasses

Red Blue 3D Anaglyph Glasses

Red-Blue glasses are used for viewing film, TV or computer screens. Light is made up from RGB (Red Green Blue) and therefore these glasses only allow red and blue light to each eye. It's said that the red blue versions of anaglyph glasses provide a sharper, better quality image than the red green versions which are also widely available. This is why you see more red blue versions of glasses. Part of the reason appears to be that the phosphor on the blue channel of a cathode ray tube television would cause ghosting of the blue channel when you use the red green variety of this type of glasses, so red blue were preferable, these days more and more people use LED tv's or computer screens so it's not the issue it used to be and now comes down to personal preference.

A particular 3D photograph, video or film will be split either red, green or red blue so you must have the correct glasses to suit. Check how your 3D photograph, video or film has been split before buying the appropriate glasses.

Red Green 3D Anaglyph Glasses

Red-Green glasses are used for viewing film, TV or computer screens. Light is made up from RGB (Red Green Blue) and therefore these glasses only allow red and green light to each eye.

Red, Green 3D glasses provide the same 3D effect as red blue 3D glasses, these days it comes down to personal preference.

Personally I find the image the viewer sees with red green glasses a little brighter than red/blue versions and is currently my preferred method of viewing 3D anaglyphs.

A particular photograph or film will be split either red, green or red blue so you must have the correct glasses to suit.   Check how your 3D photograph, video or film has been split before buying the appropriate glasses.

Polarised Filters

Polarising Filters 3D Glasses

RealD Cinema 3D Glasses

RealD glasses use polarising filters to present light of one wavelength to one eye and another wavelength to the other eye. This very ingenious method affords full color display of films produced by the RealD Cinema process.

Most people would have become aware of this way of viewing 3D films by the highest-grossing film to-date, Avatar. Scar3D "The blood flies off the screen" was the first full length 3D feature film to be completed in RealD 3D launching at the Cannes Film Market back in 2007.

3D GLASSES

Active Shutter glasses

Active Shutter LCD 3D Glasses

3D Active Shutter Glasses

Otherwise known as LC (Liquid Crystal) Shutter glasses. Named because of the properties of the lenses in these glasses containing liquid crystals which when a current is passed through them turn black shutting out the light. It works by shutting each lens alternately, this is then synchronised with the TV's output via infra red. The tv shows one picture for the left eye (the glasses right eye is remotely blackened) then one picture for the right eye (the left lens is blacked out). This is done at such speeds that of course you don't notice your vision is being blocked alternately. This method does not use any color filtering and therefore movies can be viewed in full color.

You require a TV or monitor with the correct specification to be able to view films or shows with these glasses along with a compatible synchronisation unit. The true refresh rate of your monitor or TV needs to be high enough to support this technology.
