Abstract

Purpose: Excessive exposure to short-wavelength visible (“blue”) light may damage retinal cells and lead to #maculardegeneration. This study is to assess the effects of #macularcarotenoids [L/Zi, lutein, #zeaxanthin, and meso-zeaxanthin] on visual performance, function, computer use exposure causing symptoms and sleep quality in healthy subjects.
Methods: We carried out a double-blind, #placebo-controlled randomized (DBPCR) study in 48 healthy young adults (mean age = 21.2 years, males and females, non- smokers, and Body mass index (BMI) <27 kg/m2). Subjects included in the study was based on minimum at least 4 hours / day (outer side activity & screen time exposure of electronic devices). Subjects were randomly assigned to ingest daily either a placebo (PLA, Safflower oil capsule/day, n = 13), or 20 mg L/Zi (20 mg L/4 mg Zi/day, n = 35).
