Purpose:This article tried to find the changes of the eye and a correlation depending on watching a smartphone
and taking in alcohol.
Methods:This paper conducted the refraction inspection, the radius of corneal curvature,
tonometry and the corneal thickness measurement and analysis for 31 persons (18 males and 13 females) who
have healthy drinking habit, not having the medical history of taking medicine related with disorders of the eye, a
mental disease, systemic disease and alcohol metabolism.
Results:Of respirations depending on watching a
smartphone, the alcohol concentration was significantly decreased in 15 minutes, 30 minutes, 45 minutes, 60
minutes and the convalescent stage. (p<0.01, p<0.001) As the result of comparing the refraction inspection after
and before watching a smartphone when drinking alcohol, there was a significant difference in the cylindrical
power and the axis. (p=0.005, p=0.001) The change of intraocular pressure depending on watching a smartphone
after drinking alcohol was decreased significantly from 30 minutes (p<0.001), and watching a smartphone didn’t
have any significant effect on the corneal thickness depending on the elapsed time from when drinking alcohol.
Conclusions:Watching a smartphone and taking in alcohol had a significant effect on the cylindrical power and
the axis. Watching a smartphone and taking in alcohol which may cause the visual function-strain are the factors
that need to consider before the refraction inspection.
