Why Vision Revival?

VISION Revival ingredients’ support on vision health is backed by science.

Support on reduction of eye fatigue and poor sleep quality due to blue light exposure

Today’s Digital Lifestyle presents a growing concern on the effect of blue light emitted from digital devices. Blue light makes up of some of the highest energy light which can damage the eye’s macula which could lead to eye strain and headaches in the short term, and possibly gradual loss of visual function in the long run. OmniActive conducted the B.L.U.E. (Blue Light User Exposure) study to examine the effects of supplementation with Lutemax 2020 to support visual performance during prolonged screen time.

Lutemax 2020 beadiet contains all three macular carotenoids— lutein, RR-zeaxanthin and RS [meso]-zeaxanthin1.  Lutemax 2020 beadiet was recently proven in a 6-month randomized, double-blind, placebo-controlled trial called B.L.U.E. (Blue Light User Exposure) that supplementation with Lutemax 2020 beadiet have beneficial effects on reducing side effects of prolonged screen time, including eye strain and fatigue as well as improve sleep quality, vision health and performance2.

Bilberry a powerful natural antioxidant has been clinically studied and demonstrated to lessen the symptoms of eye fatigue, Video Display Terminal load-induced ocular fatigue sensation, ocular pain, eye heaviness, uncomfortable sensation, and foreign body sensation3.

Support on reduction of the risk of Age-Related Macular Degeneration (AMD), cataracts and glaucoma

Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in adults over age 50. This eye disease occurs when there are changes to the macula, a small portion of the retina that is located on the inside back layer of the eye4.

Cataract formation - The deficiency of glutathione levels contributes to the formation of cataract. Nutrients to increase glutathione levels and activity include lipoic acid, vitamins E and C, and selenium. Cataract patients also tend to be deficient in vitamin A and the carotenes, lutein and zeaxanthin. Other nutrients and botanicals, which may benefit cataract patients or help prevent cataracts, include pantetheine, folic acid, melatonin, and bilberry.

American National Eye Institute conducted the landmark Age-Related Eye Disease Study (AREDS) a large randomized clinical trial, and found that participants at high risk of developing advanced AMD (i.e., those with intermediate AMD or those with advanced AMD in one eye) reduced their risk of developing advanced AMD by 25% by taking a daily supplement containing vitamin E (400 IU dl-alpha-tocopheryl acetate), beta-carotene (15 mg), vitamin C (500 mg), zinc (80 mg), and copper (2 mg) compared to participants taking a placebo over 5 years5. A follow-up AREDS2 study confirmed the value of this in reducing the progression of AMD over a median follow-up period of 5 years. In AREDS2, formulation changes include lutein + zeaxanthin and omega-3 fatty acids and replacement of beta-carotene6.

Bilberry contains anthocyanoside which are powerful antioxidants contains flavonoids which helps improve blood flow and that help support eye function7. Bilberry may help prevent diabetes- and hypertension-related blood vessel damage known to impair the retina (a nerve layer involved in sensing light). The antioxidants in bilberry are also thought to strengthen the walls of blood vessels, as well as curb inflammation8.

Lycopene, a naturally occurring red carotenoid pigment, was discovered by the Department of Pharmacology at the All India Institute of Medical Sciences to have the ability to prevent or delay cataracts in a large majority of cases9

Lycopene which has both an antioxidant and anti-inflammatory properties was also studied and demonstrated in a study out of Taiwan published in Life Sciences to slow down or stopped reactions within the cells of the eye that lead to macular degeneration10.

Alpha-lipoic acid an organic compound found in all human cells has been studied and demonstrated to ease symptoms of nerve damage and lower the risk of diabetic retinopathy (eye damage) that can occur with poorly controlled diabetes11.

Grape seed extract contains the antioxidant compound oligomeric proanthocyanidin (OPC), which has been studied to protect  the eye from complication related to diabetes vision problems and in preventing macular degeneration12.  Grape seed extract has also been studied and demonstrated to attenuate the process and finally cause slowing or inhibition of cataract formation13

Rutin is a plant-based bioflavonoid found in a number of citrus fruits has been studied and demonstrated to hamper the formation of advanced glycation end products (AGE) protein which is the primary cause of cataracts14.

L-Taurine is a sulfur-containing amino acid is necessary for the chemical reactions to produce normal vision. It is also studied and demonstrated to protect ocular tissue from oxidative stress and prevent and possibly reverse age-related cataracts15.

Selenium (Amino acid chelate), an essential trace mineral, is a component of the antioxidant enzyme glutathione peroxidase which is important in slowing the progression of AMD and other eye disorders including cataracts and glaucoma18.

Quercetin Dihydrate is a plant pigment (flavonoid) studied and demonstrated to have protective effect on retinal cells. Retinal cells found at the back of the eyes act as light receptors and play an important role in setting the color, resolution, and brightness of your vision19-20.

Chromium is an essential mineral that help regulates intraocular eye pressure and prevent glaucoma21.

Methylcobalamin is a naturally occurring type of vitamin B12. A study has indicated the daily supplementation of Methylcobalamin may reduce the risk of AMD22.

A study on Lutein, Zeaxanthin and Vitamin E was associated with a significantly decreased risk of cataract formation23.

VISION Revival support on night vision

Zinc has a clinical study that may support better night vision by potentiating the effects of Vitamin A24.  


VISION Revival’s ingredients’ support sleep quality, mental acuity and neuroprotection are backed by science.

How Does Vision Revival Work?

Role of Lutein and the zeaxanthin in powerful antioxidants

Lutein and the zeaxanthin are found in high concentration in the macula—a region of the eye that provides the highest visual acuity and is also exposed to high levels of blue light. As potent antioxidants and filters of blue light, lutein and the zeaxanthin play a critical role in preserving visual function, especially as exposure to blue light from a variety of sources has steadily increased1. Lutein and zeaxanthin isomers from Lutemax 2020 were shown to down regulate the genes involved in causing endoplasmic reticulum stress, and thereby protect the sensitive photoreceptors when exposed to blue light2.

Note that the amount of lutein and zeaxanthin in the macular region of the retina is measured as macular pigment optical density (MPOD). Recently, MPOD has become a useful biomarker for predicting disease and visual function4

Lutein and zeaxanthin act as antioxidants nutrients which neutralizes free radicals (unstable molecules) that are associated with oxidative stress and retinal damage. This is why the antioxidants lutein and zeaxanthin likely play a role in preventing cataracts28

Role of Vision Revival’s ingredients as a powerful antioxidant

Bilberry contains naturally producing chemicals known as anthocyanosides. Anthocyanosides are plant pigments that have powerful antioxidant properties which in turn maintain glutathione levels as antioxidant defense system within the lens of the eye. This anthocyanoside extract helps improve blood flow and contains flavonoids that help support eye function. The antioxidants in bilberry are also thought to strengthen the walls of blood vessels, as well as curb inflammation7-8.

Lipoic acid, vitamins E and C, and selenium act as nutrients to increase glutathione levels and antioxidant defense system within the lens of the eye.

Eyebright contains compounds called tannins, which appear to possess anti-inflammatory properties25.

Lycopene is a phytonutrient which are antioxidants found in plants. These act as defense against free radicals to run free within the plant, it creates various types of phytonutrients to protect eyes from oxidative stress that causes common eye diseases9-10.

Alpha-lipoic acid is an organic compound found in the body which acts to turn nutrients to energy and helps prevent cell damage in the body11.

Grape seed extract, as a bioflavonoid, is a potent antioxidant. Plant-derived bioflavonoids appear to protect retinal ganglion cells. Grape seeds are rich in natural plant compounds called oligomeric proanthocyanidin complexes (OPCs)12-13.

Rutin is a plant-based bioflavonoid that has been studied and demonstrated to hamper the formation of advanced glycation end products (AGE) and preventing cataracts to appear. Rutin may also inhibit aldolase reductase activity which helps convert glucose into sugar alcohol known as sorbitol. When excessive sorbitol is trapped in the eye and nerve cells it can damage the eye. Thus, the fact that Rutin prevents the intracellular accumulation of sorbitol is therapeutic to the eye14.

Taurine is a sulfur-containing amino acid protects against free radicals, and acts an ocular cleaner, helping the macrophages in the retina eliminate debris from the photoreceptor cells. Taurine is necessary for the chemical reactions that produce normal vision, and deficiencies are associated with retinal degeneration. Besides protecting the retina, taurine may help prevent and possibly reverse age-related cataracts. In addition, taurine counterbalances excessive levels of glutamate and excitatory neurotransmitters and protects ocular tissue against oxidative stress and ischemia15.

N-Acetyl-Cysteine NAC is an amino acid which helps replenish glutathione, The concentration of glutathione in the lens of the eye is higher than in most other tissues. It functions to protect the structural proteins and enzymes necessary for the maintenance of lens flexibility and clarity against free radical assault. Aging lenses or lenses that are under oxidative stress lose glutathione, and this shrinkage of the glutathione pool has been found to lead directly to reactions that cause crosslinking of proteins and lens opacification16-17

Iron, zinc, copper, and selenium are essential trace elements that play key roles in retinal physiology.  Copper is necessary for the synthesis of melanin, a storage protein for iron, zinc, and copper in Retinal Pigment Epithelium and melanocytes 5-6.  

Selenium, an essential trace mineral, is a component of the antioxidant enzyme glutathione peroxidase, important in slowing the progression of AMD and other eye disorders including cataracts and glaucoma18.

Quercetin is a powerful flavonoid found to have regulate inflammation, cellular metabolism, and extracellular matrix deposition. As a potent antioxidant, quercetin has the ability to protect the retinal cells19-20

Chromium is a mineral which acts to regulates intraocular eye pressure. A little pressure is good, but too much can lead to vision conditions such as glaucoma.

Vitamin C is a powerful antioxidant which helps the body form and maintain connective tissue, including collagen found in the cornea of the eye. Long-term vitamin C consumption may help reduce cataract risk and vision loss from macular degeneration.  Vitamin C is used in the treatment and prevention of glaucoma as it helps maintain collagen eye tissue28

Methylcobalamin a type of vitamin B12 plays a key role in the functioning of the brain and nerves, as well as in the formation of red blood cells. In addition, the body uses vitamin B12 in energy production and regulation, among other metabolic roles22.
