The Role of Macular Protective Pigment in AMD, Visual Performance, Computer Vision Syndrome (CVS)
Scientists have discovered that AMD is, in part, the result of a low level of protective pigment in the macula, also refered to as the Macular Pigment Optical Density (MPOD). The higher the level of MPOD, the better protection one has against retinal damage from blue light and oxidative stress. Similarly, a low MPOD is also known to be related to Computer Vision Syndrome (CVS) caused by computer usage and the contemporary technological generation. This condition targets the younger demographic. Lumega-Z encompasses both groups suffering from a depleted macular protective pigment.
Relevant Research on the MPOD Benefits of Lutein, Zeaxanthin and Meso-Zeaxanthin
- Meso-zeaxanthin a key proprietary ingredient of Lumega-Z, unlike lutein and zeaxanthin, is not found in the diet, but is converted in the center of the macula from ingested lutein (a process suspected to diminish with age). Patients with macular degeneration have been shown to have 30% less meso-zeaxanthin in their macula compared to healthy eyes. If taken as a supplement, meso-zeaxanthin is absorbed into the blood stream and effectively increases macular pigment levels.
- Research also reveals that lutein and zeaxanthin promote glare relief and recovery and improve contrast acuity — a benefit to people of all ages. These carotenoids have also been shown to enhance the ability to see in dim light, protect against eye fatigue, and improve distance vision, resulting in enhanced driving safety.
- Augmentation of the macular pigment optical density across its spatial profile and enhancements in contrast sensitivity were best achieved after supplementation with a formulation containing high doses of meso-zeaxanthin in combination with lutein and zeaxanthin..
- MPOD is associated with global cognition, executive function, processing speed, and PM in a large, nationally representative study of older adults. This is a novel and important finding as it supports the thesis that MPOD measurement could offer a quick and noninvasive tool to assess this aspect of cognitive vulnerability in clinical practice (Johnson, 2012) and that dietary supplementation with L, Z, and MZ may offer a degree of neuroprotection in individuals with insufficient levels.
