Visual protective sheet can increase blink rate while playing a hand-held video game.
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.
