Investigating Associations Between Chronic Electronic Device Blue Light Exposure, Dietary Xanthophyll Intake and Macular Pigment Density in Humans.

The University of Queensland·observational·Posted Mar 3, 2021·Updated May 19, 2022

In Brief

An observational study for Age Related Macular Degeneration. Completed, enrolled 96 participants across 1 site.

Detailed Summary

This study aims to investigate in healthy adults 18-65 years of age the association of electronic device blue light exposure and macular pigment optical density (MPOD) considering usual dietary intake of lutein and zeaxanthin (L/Z) as confirmed by serum lutein and zeaxanthin concentrations. It is hypothesised in healthy adults 18-65 years of age: 1. Higher usual daily electronic device blue light exposure will be negatively correlated with MPOD value. 2. Usual dietary intake of L/Z will be positively correlated with MPOD value. 3. L/Z concentration will be positively correlated with MPOD value. 4. Usual dietary intake of L/Z will be positively correlated with plasma L/Z concentrations. 5. Higher usual intake of L/Z will mitigate the effect of higher electronic device exposure on MPOD value.
