title: Visual protective sheet can increase blink rate while playing a hand-held video game.
abstract: OBJECTIVE
  To evaluate the effectiveness of a protective sheet in reducing eye strain caused by unnecessary light reflection on portable liquid crystal display panels while playing Game Boy (Nintendo, Kyoto, Japan).
  
  
  METHODS
  Nonrandomized clinical trial.
  
  
  METHODS
  The blink rates of 24 normal volunteers were measured under relaxed conditions while viewing a portable liquid crystal display panel and playing Game Boy with and without the protective sheet of polyethylene terephthalate with antiglare coating for a total of 10 minutes each.
  
  
  RESULTS
  The results showed a dramatic increase (from 5.6 +/- 3 to 9.1 +/- 4.9 [P <.0001]) in blinks/minute with use of the protective sheet.
  
  
  CONCLUSIONS
  The protective sheet has shown the possibility of increasing the blink rate by making the screen easier to see.
