We thanks Dr SMJ Mortazavi for interest in our recent publication.1
Regarding to his first comments on “smartphone blue light filter”. We agree with his opinion in terms of blue light suppressing the secretion of melatonin, which possibly causes circadian rhythm disruption.2 Though most applications are available in modern smartphones, people are mostly not aware of the dangers of the blue light, hence they usually do not apply the blue light filter for protection, especially in Taiwan and China.3 That is why we did not consider this factor would affect our result. All participants stand on the same baseline.
