ST. LOUIS, Aug. 11, 2015 /PRNewswire/ -- Many don't realize that certain metabolic disorders can affect vision long before diagnosis, especially if blood glucose levels have been unregulated or inadequately regulated for long periods of time. As a result, vision performance or quality parameters such as color vision and contrast sensitivity can diminish over time. A recently published landmark clinical research study demonstrated that a nutritional supplement can improve vision quality in subjects without affecting blood glucose levels.
A science-based nutritional supplement was studied by leading investigators in the Diabetes Visual Function Supplement Study. (DiVFuSS) The results of this six-month clinical trial were published in June 2015, in the British Journal of Ophthalmology. The supplement was found to significantly:
- Increase contrast sensitivity by 28%
- Improve color vision by 42%
- Increase Macular Pigment Optical Density (MPOD) by 27%
Sixty-seven subjects participated in the DiVFuSS study, a randomized, controlled clinical study designed to determine if a novel, multi-component nutritional supplement could be of benefit to patients with Type 1 and Type 2 diabetes.
One study group ingested two softgels of the EyePromise DVS supplement daily, and the control group was administered a placebo. All subjects underwent a thorough case history and comprehensive dilated eye examination prior to study enrollment. Contrast sensitivity, MPOD, color discrimination, and other parameters were measured before, during, and after the study.
There were no meaningful differences between the study groups at baseline however after six months of supplementation subjects taking EyePromise DVS experienced significantly improved visual function parameters.
"DiVFuSS demonstrates that clinically meaningful improvements in visual function can be realized with a novel, multicomponent nutritional formula in patients with long or short term diabetes duration, whether Type 1 or 2," said Dr. A. Paul Chous, lead investigator of the study. "Our findings suggest the DiVFuSS supplement formula positively influences diabetes-induced visual dysfunction."
"Numerous clinical research studies have demonstrated that nutritional intake of certain phytonutrients affects vision quality and eye health," said Dr. Dennis Gierhart, founder of ZeaVision, the maker of EyePromise DVS, the nutritional supplement evaluated in the study. "Nutrients vital to eye health can enhance vision quality and performance in multiple ways."
What is vision performance?
Vision performance includes parameters such as visual acuity, color vision and contrast sensitivity. Visual acuity is how clearly one sees at short and long distances. Color vision is one's ability to discern and distinguish shades of color. Contrast sensitivity is a measure of one's ability to distinguish objects against a similarly colored background. Good contrast sensitivity is a particularly important safety factor when driving in low light conditions at dawn, dusk or night.
Certain metabolic disorders in which blood glucose levels become unregulated can cause progressive damage to the retina in the back of the eye. This type of deterioration is a leading cause of visual impairment worldwide.
The macular pigments are antioxidants and photo-protectants that protect retinal tissues from oxidative stress and light damage. The macular pigments are diet derived and filter harmful light to protect one's photo-receptors. They have also been clinically demonstrated to improve vision performance factors such as acuity, contrast sensitivity, bright light sensitivity, and glare recovery time. Low macular pigment optical density (MPOD) has also been associated with an increased risk of Age-related Macular Degeneration (AMD), a serious retinal health issue. Low MPOD levels have also been documented in multiple clinical studies of subjects with blood glucose control issues.
Zeaxanthin and lutein make up the diet derived macular pigments at a ratio of 2 to 1 respectively in the center of the macula. The macular pigments cannot be produced by the human body and therefore must be obtained via dietary intake of dark green leafy vegetables such as spinach and kale or brightly colored vegetables such as orange peppers. Taking a nutritional supplement like EyePromise DVS can augment one's diet to support eye health.
EyePromise eye vitamins are supported by an unconditional 60-day, money-back guarantee and are guaranteed to increase MPOD. To locate an eye care professional in your area who can measure your MPOD please contact ZeaVision at the number provided below.
