Dry eye syndrome is a common pathological condition associated with burning eyes, where a person feels stinging or the presence of grains or something in the eye, which causes a state of discomfort and constant discomfort, in addition to blurred vision and redness or irritation of the eye.
In detail, the reduced ability to produce tears in the lacrimal glands causes the problem of dry eyes, which limits the continuous and natural hydration process of the eye, and causes its early aging due to a group of factors related to allergies, hormonal changes, the environment and prolonged sitting in front of a computer screen or mobile devices, which are factors It is closely related to the problem of dry eye.
Doctors prescribe a group of drops and ointments to treat dry eye syndrome, but some studies revealed a nutritional supplement capable of reducing this problem and preventing premature eye aging, according to Sputnik.
According to the article published in the journal “verywellhealth” specialized in health news, supplements of “omega-3” fatty, or fish oil, which is found in a number of fish species, is highly associated with eye health and preventing its dryness.
The omega-3 fatty acids found in fish oil supplements are known to offer many benefits due to their antioxidant and anti-inflammatory properties.
There are three types of “omega-3” essential fatty acids, which are all beneficial for the health of the body and brain, namely:
1- Alpha-linolenic acid (ALA)
2- Eicosapentaenoic acid (EPA)
3- Docosahexaenoic acid (DHA)
Scientists have extensively studied the effects of these powerful nutrients, and researchers have found that they reduce the risk of chronic diseases, including arthritis, cancer and heart disease.
One of the omega-3s, docosahexaenoic acid (DHA), plays an essential role in eye health and eye function, with research confirming that omega-3s may “help prevent visual impairment and blindness caused by macular degeneration.”
A 2019 scientific review of 34 different studies found that omega-3 supplementation may help reduce, and is associated with, dry eye disease.
Despite this information, the researchers note that “the evidence is inconsistent” and has not yet been confirmed and needs independent study to confirm it.
Another study published in Oxford’s “The American Journal of Clinical Nutrition” (AJCN), published in the February 2001 issue, reports an association between eye health and omega-3 fatty acid supplementation.
The study confirmed that eating more fish or “omega-3” may help promote macular health.
According to Bausch & Lomb, a health website, it is believed that omega-3 supplements play an important role in eye health, because DHA is naturally concentrated in the retina (the layer of tissue that lines the inside of the eye and receives the image formed by the lens) and is believed to enhance For healthy retinal function, studies also show that omega-3s can help reduce dry eye syndrome.
