Abstract: The study on Long Term Blue Light Exposure Effect on Macular Pigment Optical Density (MPOD) was a survey research with the objective to compare macular pigment optical density level (MPOD) between infrequent/low-usage persons (≤ 5 hours/day) and frequent/high-usage persons (≥ 9 hours/day) that use electronic devices. The sample group was consisted of 162 male and female subjects. The subjects were classified into 3 groups, e.g., the low usage with time spent on electronic device ≤ 5 hours/day, the moderate usage with time spent 5.1-8.9 hours/day, and the high usage with time spent ≥ 9 hours/day. Subjects were required to complete personal data record form and capture measurement of MPOD level by using Macular Pigment Optical Densitometer (M-POD). The result showed that the difference in MPOD levels in each usage category were statistically significant at p < 0.05. The mean of MPOD levels of the Low Usage was significantly higher than that of the Moderate Usage (0.68±0.14 and 0.53±0.11, p < 0.05 respectively). The mean of MPOD levels of the Moderate Usage was significantly higher than that of the High Usage (0.53±0.11 and 0.38±0.10; p < 0.05 respectively). And the mean of MPOD levels of the Low Usage was also significantly higher than that of the High Usage (0.68±0.14 and 0.38±0.10, p < 0.05 respectively). The result from comparing MPOD levels between the low-usage persons (≤ 5 hours/day) and the high-usage persons (≥ 9 hours/day) showed that the low-usage persons had higher MPOD level than that of the high-usage persons. There was a correlation between the usage or using electronic devices for a long period of time and MPOD level. Higher usage of electronic devices lead to the lower of MPOD level.
