Guardion Health Sciences is a specialty health sciences company formed to develop, formulate and distribute condition-specific medical foods with an initial medical food product on the market under the brand name Lumega-Z that replenishes and restores the macular protective pigment. A depleted macular protective pigment is a modifiable risk factor for retina-based diseases such as age-related macular degeneration (AMD), computer vision syndrome and diabetic retinopathy. This risk may be modified by taking Lumega-Z to maintain a healthy macular protective pigment. Additional research has also shown a depleted macular protective pigment to be a biomarker for neurodegenerative diseases such as Alzheimer’s disease and dementia. In 2017, we acquired VectorVision, which specializes in visual acuity testing for contrast sensitivity, glare sensitivity, low contrast acuity, and early treatment diabetic retinopathy. We invented a proprietary medical device, the MapcatSF, that accurately measures macular pigment optical density. By combining the MapcatSF medical device, the newly acquired VectorVision vision testing technology and Lumega-Z medical food, we developed what we believe is a three-pronged, evidence-based protocol for replenishing and restoring the macular protective pigment, increasing overall retinal health and measuring the related improvements in visual function.
