The syndrome of “dry eye” (keratoconjunctivitis sicca dry) is a chronic eye disease, characterized by reduced production of tears. This disease is almost never a man loses sight, but his quality of life is deteriorating. Fortunately, to help in the syndrome of “dry eye” can vitamins and minerals, writes likar.info.
Nutrition from food we get all the vitamins and minerals necessary for the human body. However, some people due to various reasons in the body can be lack of vitamins and minerals, therefore they must be taken separately.
Eyes and vitamins
Some scientific studies have shown that vitamin supplements can benefit the eyes of older people which have problems with digestion. So, for example, vitamins A, C and E can reduce the risk of macular degeneration of the retina (JP), a disease that affects the retina and interferes with Central vision.
There is also scientific evidence that taking certain vitamins (particularly b vitamins) and minerals lowers the risk of cataract partial or complete opacity of the lens of the eye. The fact that thiamine and other b vitamins help to give the muscles and the nerves signals from the brain to the eyes.
The lack of thiamine (vitamin B1) increases the risk of cataracts. Poor memory, poor appetite, poor sleep, lack of energy, fast weight loss is a symptom of what the body little thiamine.
What vitamins and minerals are useful in the syndrome of “dry eye”
In fact, while there is little scientific evidence that vitamins help treat the syndrome of “dry eye”. If you read the statement that a particular vitamin complex promises to help in the treatment of this disease, should be treated critically. At the moment scientists can say with certainty that vitamins only improve the General condition of the body, and in this sense they are useful in the syndrome of “dry eye”. However, some vitamins and minerals people with this eye disease still need to pay attention to.
The syndrome of “dry eye” often there is a deficiency of vitamin A. It usually is not enough due to poor nutrition. So, in some developing countries 50% of children of preschool age the body lacks vitamin A. Lack of this vitamin happens when the person has digestive problems (in these cases it’s hard to digest all the vitamins and minerals).
By the way, vitamin a is part of many medicines for the treatment of the syndrome of “dry eye”. It is a natural part of the tear film (enhances the formation of the inner mucin layer of the tear film, support the outer lipid layer of the tear film, stimulate regeneration of the corneal epithelium reduces the number of dead cells).
Vitamin a is very useful for the eyes. However, sometimes it can hurt. So, its excessive consumption may accelerate vision loss and retinal degeneration in humans with recessive disease of Stargardt and other retinal disorders, and also lead to blurred vision.
A few years ago, scientists studies concluded that vitamin D may be a good preventive measure to prevent the syndrome of “dry eye”. It can also reduce the symptoms of this disease. In particular, it reduces the inflammation of the surface of the eye, blurred vision and sensitivity to light. However, scientists have yet to conduct further studies of how this vitamin decreases symptoms of dry eye.
Excessive consumption of vitamin D rarely leads to negative consequences for health, but they can be very serious. Because of the large quantities of this vitamin in the blood can accumulate calcium, leading for example to nausea. Sometimes excessive vitamin D causes problems with the kidneys.
Vitamin E is a powerful antioxidant. It is contained in large amounts in vegetable oils (sunflower, corn, soybean oil), beef liver, peas, rose hips. Vitamin E is often an ingredient in medical products intended for treatment of the syndrome of “dry eye”, as it stimulates epithelization of superficial defects of the cornea.
In the treatment of the syndrome of “dry eye” can be useful omega-3 fatty acids, the experts say American Academy of Ophthalmology. In turn, experts at the us National Eye Institute believe that omega-3 fatty acids decrease symptoms of irritation in people with the syndrome of “dry eye.”
In this disease can help of omega-3 fatty acids called DHA and EPA. In large quantities found in fish (herring, mackerel, anchovies, salmon, sardines, tuna).
It should be noted that in 2013 in the journal of the National Cancer Institute published an article by American scientists, who claimed that excessive consumption of omega-3 fatty acids increase the risk of prostate cancer. But we should not immediately abandon these acids. The American Management on sanitary inspection behind quality of foodstuff and medicines says that if a person receives daily from food or supplementation of 3 grams of the acids DHA and EPA, they are harmless.
Omega-3 fatty acids can cause lowered blood pressure, and also affect the health of people with diabetes or hypoglycemia. So before you start to use them for the treatment of the syndrome of “dry eye”, you need to consult your doctor.
The ionic minerals intended for proper hydration of the human body. They have moisturizing effect as well in the syndrome of “dry eye”.
Glucosamine and chondroitin sulfate
Glucosamine and chondroitin sulfate, substances involved in the synthesis of connective tissue, are highly effective in the treatment of the syndrome of “dry eye”. Anyway, these are preliminary conclusions of a scientific study. Scientists have yet to pinpoint the role of these substances in the treatment of diseases of the eye.
As vitamins and minerals available to the public, it may be tempting to immediately use them at the first signs of the syndrome of “dry eye”. But no need to rush. In the beginning it is better to consult the doctor. The fact that vitamins are easy to overdose on, they interact with some medicines, and, most importantly, the syndrome of “dry eye” can be caused by any autoimmune disorder.
