Looking to naturally improve vision and cognitive function? Not sure which lack of nutrients are forcing you to experience eye irritation, inflammation and/or dryness? One team believes the answer to this rests in a precise combination of antioxidants. As it turns out, there are hundreds of thousands of different antioxidants out there. To free individuals from spending hours on end on research, the makers decided to not only take over research, but to also create the formula. The purpose of this review is to introduce the lo and behold, SightCare.
What is SightCare?
SightCare is a 100% natural vision support formulated to support long-lasting vision all while tending to brain health. In fact, the synergy created between the ingredients is poised to heighten energy levels, liver function and visual acuity to say the least. Although it is true that the details are in the pudding, effectiveness can also be assessed by addressing two areas: 1) the SightCare mechanism and 2) the classification of the selected ingredients. Having said that, let’s turn our attention to the SightCare mechanism.
How does SightCare work?
Earlier, the makers of SightCare insisted that this formula will aid in the betterment of both brain and eye functions. So, naturally that got us thinking what the potential link may be. In search of answers, our editorial team landed on a piece that shares the opinions of several neurologists.
According to Dr. Begeti [1], the cause-and-effect relationship between vision loss and decline in cognitive function is still unclear. However, he believes that “Conditions such as diabetes and high blood pressure affect blood vessels to both the brain and eyes, leading to cognitive impairment and visual loss concurrently.” In other words, the same health issues are negatively impacting both organs.
The aforesaid clearly doesn’t answer how this formula is intended to work. It was only after investigating the ingredient’s list that we were able to arrive at some conclusion. Precisely, SightCare largely carries antioxidants reckoned to defeat the impact of reactive oxidative stress and other harmful invaders.
One source explained that oxidative stress is introduced when there is an imbalance between ROS and antioxidants. And so, “Ample antioxidant defenses are responsible for scavenging free radicals are essential for redo homeostasis in the eye, indeed eye tissues, starting from the tear film, which normally are exposed to high oxygen levels [2].”
Like the eyes, the brain is also vulnerable to oxidation. This is mainly because the brain contains a lot of lipid content, requires a lot of energy, and has a weak antioxidant capacity, insists one review. They further highlighted that ROS increases the odds of neuronal damage and functional deficits. Hence, it becomes more than imperative to include various antioxidants for the neuroprotection of the brain, especially amidst oxidative injury [3].
Now that a possible cause for poor vision and brain function has been identified, the next step is to assess which among the various antioxidants available has qualified for SightCare.
What ingredients are inside SightCare?
The main ingredients inside SightCare include:
Astaxanthin
Astaxanthin is a carotenoid (or a red pigment extracted from certain plants and animals). A review that reported on the clinical applications of the pigment on treating ocular diseases justified its uses by its strong antioxidant, anti-inflammatory and antiapoptotic activities. Furthermore, this carotenoid supposedly has the advantage of addressing the main pathogenic factors behind ocular diseases (i.e., cumulative oxidative stress and chronic subclinical inflammation) [4].
A 2012 study that examined the topical administration of astaxanthin eye drops on UV-photokeratitis in mice reported that the carotenoid could potentially limit the damages of UV irradiation in the eyes as well [5]. Regarding brain health, latest research suggests it may prevent neurological pathologies including Alzheimer and Parkinson diseases. This mostly has to do with its capability to cross the blood-brain barrier and as well as its antioxidative, anti-inflammatory and anti-apoptotic properties [6].
Bilberry Fruit
Bilberries are small, blueberries grown in Northern Europe. This nutrient-rich fruit is packed with antioxidants (from vitamin C and phenolic acids), essential for protecting the body against damage and disease. On the topic of vision support, one source explained that it may have a positive effect on night vision, however the evidence is supposedly not strong enough. Luckily, there are other ways through which bilberry can positively influence vision. Some examples include improving visual function of people with glaucoma, eye dryness and eye fatigue [7]. The same source hinted improvement of brain function in the long run as well as working memory in older adults.
Lutein & Zeaxanthin
The two most powerful and well-recognized carotenoids known to humankind, primarily in the context of vision health are lutein and zeaxanthin. Their abundance of antioxidants ensures utmost protection against free radicals. In one piece, it was mentioned how this duo is vital for not only protecting the eyes against harmful invaders, but also oxidative damage. The latter occurs when there is an imbalance in antioxidants and ROS [8].
Interestingly, when lutein is paired with bilberry, vision benefits may be accelerated. Some examples include the possibility of preventing macular degeneration, keeping the retina healthy, and supporting immune function [9]. Finally, the lutein and zeaxanthin may work together to increase neural activation. A group of researchers examined the effects of 10mg of lutein and 2mg of zeaxanthin versus a placebo on brain function for one year. By the end, the former duo led to a positive impact on higher level of brain functions [10].
Eyebright & Quercetin
Eyebright is an herb found commonly in parts of Europe, Asia, and North America. Some of its beneficial properties stem from flavonoids such as luteolin and quercetin. This particular duo is trusted to inhibit immune cells called mast cells, which release a compound called histamine, usually causing symptoms linked to seasonal changes. In terms of eye health, it may relieve eye irritation, control inflammation in the human cornea cells, protect cornea cells from UV, and relief of eye redness, swelling and burning among others [11].
All things considered, no studies examined the effect of Eyebright on major eye diseases such as macular degeneration, cataracts, or glaucoma. It looks like Eyebright-derived quercetin was not enough for this team, leading them to add extra! Finally, unlike the aforesaid ingredients, Eyebright does not seem to have a direct impact on the brain.
N-Acetyl Cysteine
The last antioxidant to have qualified for the SightCare formula is N-acetyl cysteine. This ingredient is commonly used to defeat coughs, flu, and dry eyes [12]. Another piece that highlighted its properties also reported its potential in alleviating eye conditions linked to eyelid inflammation, redness, and eye irritation. Also referred to as blepharitis, N-acetyl cysteine may improve the function of meibomian glands (i.e., oil glands), consequently reducing the condition’s symptoms [13].
Frequently Asked Questions (FAQS)
