While doing some research for my upcoming Dry Eye column in OSN, I was reacquainted with the scientific publishing site PLoS One. Man, is there a lot of fun stuff there! I’ve got a pretty vivid imagination, full of all kinds of ideas for projects and research, but even I wouldn’t think of putting rats on a swing to investigate DES associated with computer use. Nakamura, Imada and their co-authors used this model to evaluate the stress placed on lacrimal gland secretion with prolonged near vision/low blink rate activities. They showed that both the swinging rats and office workers evaluated showed a decrease in tear production that was “dose-related”: More hours exposed, both cumulative and per session, resulted in a greater decrease in tear generation.
