|
Purpose. To investigate the relationship between changes in eye temperature and eye fatigue according to smartphone usage time.
Methods. 15 adults in their 20s were asked to watch a smartphone, and the ocular surface temperature was measured 5 times each using a non-contact infrared thermometer every 10 minutes, and the change was observed.
Result. The ocular surface temperature was 36.40℃ at the center of the cornea before watching the smartphone, but increased by 0.19℃ to 36.59℃ after watching the smartphone (SD 36.50±0.10). In addition, in the case of the sclera, it was found that the increase was 0.1℃ from 36.48℃ before viewing to 36.58℃ after viewing (SD 36.53±0.05).
Conclusion. It was found that there is a close relationship between smartphone use and changes in eye temperature. In the future, it is thought that the ocular surface temperature can be used as basic data to objectively evaluate eye fatigue.
