Movie blockbuster Avatar has caused a craze across the globe and not just for its surreal and fanciful storyline; the 3D version has generated a Harry Potter-like obsession with glasses. But while offering a fun and alternative cinema experience, 3D movie viewing isn’t for everyone .

“People with sensitive eyes or certain eye conditions may find their vision blurry and therefore a little distracting. Those required to wear 3D glasses on top of their prescription glasses may find the extra layer a little uncomfortable, but the glasses themselves won’t damage the eyes or impair your vision,” .

All 3D glasses work by filtering images so that the left eye sees one image, and the right eye sees a slightly different image. It’s then up to the brain to fuse them together so that you perceive a 3D image. Obviously, the eyes have to work well together for this process to happen.

“Optometrists can measure the amount of 3D vision you have, also known as stereopsis. In some circumstances stereopsis can be improved with vision correction or vision therapy”.

Optometrists Association Australia recommends that viewing 3D movies or television programs shouldn’t be treated any differently to 2D versions.

“When watching any movie or television program it is important to sit at a comfortable distance from the screen so that any neck or eye strain is minimised,”.

“Anyone who experiences a vision condition such as blur, spots, tiredness or redness while watching a movie or playing computer games in 3D or 2D should have their eyes examined by an eye care professional”.

Top Tips: Caring for eyes in front of the screen

• If you notice anything unusual with your vision while focussing on the television or cinema screen consult your optometrist.

• Before using 3D glasses read the warning labels.

• Do not use 3D glasses as an alternative to sunglasses.
