topicLutein Supplementation Eye Strain Randomized Trial
claimThis systematic review aimed to evaluate randomized controlled trial (RCT) evidence on the effects of carotenoids, anthocyanins, polyunsaturated fatty acids, and combined nutraceutical formulations on refractive outcomes, axial length, macular pigment optical density (MPOD), visual function, and symptoms of visual fatigue.
