Eye health is an essential part of your health and is very important in everyday life. You can sense the surrounding world using your eyesight. We see and perceive others with eyes, and others see and perceive us with eyes – as we know, eyes are the windows to our soul. They may be empty and lifeless as if no one was home – or clear, radiant, and full of life. They can reflect anger and fear or care, trust, and curiosity. We see not only physically, but also psychologically and emotionally. To see is to perceive, to feel, to understand, to know.

Images generated by nerve impulses are sent from the retina to the brain, which means that clear vision does not depend on eyes as much as on a well-functioning nervous system. If we do not like what we see, we can close our eyes and refuse to look. The worsening of vision is often caused by genetical and environmental factors or disease (diabetes), but it may also on a psychological and emotional level relate to the desire to cut oneself off from what is seen.

Eye health from a holistic perspective

Fear about the future can be listed as an example of something that can cloud seeing to the distance. Or vice versa – the fear of being present and seeing yourself may blur near vision. Sensitive children take over their parents’ fears and the eye problems of children often reflect the relationship between parents or the situation at home. For example, if one parent of a child is afraid of life and of taking responsibility and escapes from frightening situations, the next generation can take over this attitude and fear that the parent might have in turn taken over from the previous generation. In this way, same patterns continue to be exhibited by next generations, until someone deliberately or unknowingly solves the problem. It is quite difficult for a child to be self-confident and to believe in a positive future when a parent or both parents reflect the opposite daily. Such fears about the future can be reflected in the deterioration of vision through the nervous system and beliefs.

If you have eye problems, you can ask yourself questions such as: “Is there something in me that I do not want to see?”, “Are there any memories, deep fears and traumas, which I have buried deep inside and which I am afraid of bringing to light?”, “Are there any freezing fears regarding the present moment or the future that affect optic nerves and blur vision?”. For example, cataract in older people may mean being afraid of the looming risk of becoming helpless, sick, and of being left alone, which they don’t want to see. Cataract symbolises the lack of light in one’s life.

Who is more deeply interested in which fears can cause loss of vision, cataract, conjunctivitis, glaucoma, short- and long-sightedness, and tear flow can buy D. Shapiro’s book Your Body Speaks Your Mind: Decoding the Emotional, Psychological, and Spiritual Messages That Underlie Illness. The book contains a lot of interesting topics and food for thought.

Unfortunately, however, decrease in vision is not yet associated with internal or external factors. Losing one’s vision with age is simply thought as inevitable. This is confirmed by statistics – cataract occurs in two thirds of people over the age of 50, but when crossing over the age of 60 years old, already 90% of people experience it. Glaucoma occurrence rate is 2% among people that are 40–50 years old and 8% in 70-year-olds. However, there are many old people whose eyesight is good and who have no problems with their eyes, and so arises the question of why some people experience a decrease in vision and others do not.

What is cataract?

The health portal Inimene.ee describes cataract as clouding of the lens in the eye which leads to a decrease in vision and is common in older age. Cataract is less frequent in children, but it is one of the most common causes of blindness in children in developed countries. The website also writes that precise causes and mechanisms of the development of cataract in adults are still not clear.

However, there is at least one doctor in the world who dared to oppose such an approach. Stanley Evans, the late British ophthalmologist, went to Africa in 1964 to study the causes of blindness and its prevention. During the 17 years that he lived there, he carried out extensive research on the causes, prevention, and prophylaxis of blindness and other eye diseases. Evans collected a series of unbelievable stories of people, who in Africa and the United Kingdom (and even in some other countries), managed to reduce or completely avoid vision problems thanks to eating right, exercising, and taking dietary supplements. Evans found that many of the visual impairments were related to a particular nutrient that humans lacked, and then, after finding out which nutrients were affecting specific parts of the eye, he developed nutritional therapy. It has helped thousands of people with various types of eye diseases that had previously been thought to be incurable.

Newer studies also show that cataract and glaucoma are preventable since their development and course is largely determined by our dietary habits, the nutritional values of our diet, and exposure to specific environmental toxins. Extensive studies have shown that drugs such as cholesterol-lowering statins, steroidal and non-steroidal anti-inflammatory drugs such as aspirin, antidepressants, anticoagulants, antacids, antibiotics, as well as contraceptive pills also increase the risk of cataract and the risk of damage to the eye lens. In most cases, the cause of eye problems is still not known, nor can it be associated with drugs, unhealthy diets, psyche, or stress associated with fears. However, despite the lack of links, our ophthalmologists do a great job, but people need to do the rest of the work for the health of their eyes by consuming versatile nutritious diets and by going over their internal sources of stress and their fears.

What is glaucoma?

Glaucoma is an increase in intraocular pressure, which can lead to damage to the optic nerve and blindness. Intraocular pressure increases due to a disorder in the circulation of the intraocular fluid (fluid flows from the front to the back of the eye). The pressure exerts pressure on the various parts of the eye, so that the optic nerve can be damaged, leading to vision declining. Glaucoma is one of the most common causes of blindness among people over 40. Traditionally, glaucoma is treated with surgery or drugs, which are designed to narrow pupils, prevent fluid secretion, facilitate its drainage and/or reduce intraocular pressure in the eye. Unfortunately, in this way, vision is corrected by eliminating the symptoms, not the causes.

Evans’s experience shows that, in many cases, glaucoma develops due to nutrients lacking. In particular, vitamin A deficiency causes cornea to soften and for its texture to change from a pearlescent glass-like texture to pale and dull. In some cases, vitamin A deficiency may even lead to cornea erosion. Vitamin A is also destroyed by excess alcohol, medicines, and processed foods with a lot of sugars.

Which vitamins strengthen your eyes?

Vitamin A

Vitamin A is an antioxidant that plays an important role in having a good vision. Vitamin A keeps the mucous membrane moist and protects from bacteria, thereby reducing the risk of inflammation. Vitamin A helps eyes to adapt in the dark, prevents blindness due to macular degeneration and the formation of cataract. Vitamin A deficiency can cause dry eyes and nyctalopia, also known as night-blindness, which is a condition that makes it difficult or impossible to see in relatively low light. Every time we are in bright sunlight, in about a few seconds, almost all the photoreceptors called rods have their pigment bleached, and for us to be able to see again in the dark, it must first be restored. This pigment is regenerated by vitamin A (retinol or carotene), which we should absorb from food. The daily recommended vitamin A intake is approximately 800 micrograms of retinol equivalent. People absorb vitamin A in the form of active retinol primarily from animal sources, such as liver and eggs. At the same time, the body can also convert beta-carotene from plant sources to retinol. Good sources of beta-carotene are yellow and orange fruits, vegetables, and berries.

Vitamin E

Vitamin E is an antioxidant that exists in many forms, but the human body best absorbs it as alpha-tocopherol. One of the symptoms of vitamin E deficiency is deterioration of vision. This vitamin that is vital for the eyes slows deterioration of the macula, prevents the formation of cataract, and strengthens the walls of capillaries. If there is enough vitamin E in the cell, its membrane works as a protective wall that prevents oxidation processes and reduces damage, in fact even preventing damage to the photoreceptors. Vitamin E also reduces eye pressure, which is the main cause of glaucoma. Vitamins C and E appear to work synergistically and help prevent inflammation in the middle part of the retina (in the macula) that degrades due to age. We get vitamin E mainly from plant-based foods, such as nuts and vegetable oils.

Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin and the main antioxidant found in many berries, fruits, and vegetables, such as citrus fruits, broccoli, turnip, bell peppers, etc. It is better to eat fresh fruits, because vitamin C is fairly sensitive to temperature, light, and oxygen. Ascorbic acid supports the blood vessels in the eyes by protecting them from swelling, by ensuring their elasticity, and by preventing cataract formation. Vitamin C does not allow the free radicals that reach the cells in the eyes to damage the DNA in the nucleus of the cells, or the many metabolic pathways in the tissues surrounding the cells. A lot of antioxidants are used in the eye to prevent light-induced oxidative damage. Vitamin C concentration in the eye is 20 times higher than in the blood. This means that, to see real effects, especially when we have already noticed the first signs of eye diseases, vitamin C and other antioxidants must be taken in significant quantities. The need increases with illnesses, and is higher for smokers, pregnant women, and nursing mothers.

Zinc

Zing has an important role to play in the health of the eyes, since there is a large amount of zinc in the retina of the eye. Zinc is a mineral that helps absorb vitamin A and creates the pigment melanin, which protects the eye from ultraviolet rays. Zinc is an important factor in the functioning of the immune system and in antioxidant defence. In addition, zinc helps to improve vision in the dark and prevents macula degradation. In the event of a severe deficiency, lack of zinc may also cause changes in the retina of the eye. Zinc is for example contained in liver, nuts, whole grain products, and seafood. The daily recommended dose is 9 mg. As absorption of zinc is inhibited by acids from plant-based sources, vegetarians should increase the amount consumed by about 30%.

Selenium

Vitamin E in turn is absorbed better thanks to the trace element selenium. Selenium is an antioxidant that also promotes the development of capillaries and supports blood circulation, including in the eyes. Selenium helps reduce the development of cataract. Good sources of selenium are fatty fish, liver, nuts, and seeds. With normal diet, a person can easily receive the daily recommended dose of 60 micrograms.

Lutein and zeaxanthin

In the human eye, there are two kinds of carotenoids – lutein and zeaxanthin. These are yellow pigments that give macula its colour. Lutein and zeaxanthin act as natural sunglasses, protecting the eyes from harmful ultraviolet rays and slowing down the destruction of macula. These carotenoids help maintain good vision, especially in low light conditions. Lutein and zeaxanthin are antioxidants that neutralise free radicals released by light exposure, which can damage the retina of the eye.

More lutein is needed by the elderly, smokers, menopausal women, and blue-eyed people who have less of the protective pigment melanin in their eyes.

All carotenoid-containing products with antioxidant properties, such as green vegetables and blue berries are good for the eyes, especially spinach, cabbage and savoy cabbage, because they contain lutein – the king of the carotenoids. Egg yolk, kiwi, grapes, and corn are also rich in lutein. Blue and crimson berries, such as blueberries, blackberries, purple and red grapes contain anthocyanins that support the ability to see in the dark.

Eye-Health-Green

Although lutein and zeaxanthin do not have specific RDA figures (recommended dietary allowance), researchers advise to consume 6–20 mg of lutein per day and the amount of zeaxanine should amount to 1/5 of lutein intake. Several studies have shown that the regular consumption of such quantities of lutein and zeaxanthin reduces the risk of age-related macular degeneration.

Astaxanthin

Astaxanthin is a carotenoid produced by the green algae Haematococcus pluvialis under sunlight. Sea birds and animals actually derive their pink colour from eating this algae that contains pink pigments. Studies have shown that astaxanthin has many times more antioxidant power than vitamins E and C, lutein, and beta-carotene. It has also been found that astaxanthin works well with other antioxidants, such as vitamins C and E, as it enhances their effect.

Eye-health-lobster

Astaxanthin is one of the few antioxidants that can pass both the brain-blood barrier of the central nervous system and the blood-retinal barrier of the eyes, helping to prevent oxidative stress and neurodegenerative damage in these areas. Astaxanthin protects eyes from damages caused by inflammation and light and helps reduce eye fatigue and dryness. This is great news for those who work on a computer every day.

Red seafood, such as crabs, lobsters, prawns, and salmon contain large amounts of astaxanthin – even a small amount of this antioxidant (4–6 mg per day) improves visual acuity.

Omega-3 fatty acids

Two essential fatty acids, omega-3 fatty acids called docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) play an important role in the development and preservation of vision. The retina of the eye contains a high amount of DHA, which indicates its importance in the metabolism of the eye. EPA plays an important role in the synthesis of DHA. Both fatty acids are very important for the development of vision in fetuses and infants, and in adults they help protect the retina of the eye. These fatty acids help keep visual acuity. Omega-3 fatty acid deficiency is associated with the dry eye syndrome. EPA and DHA help ensure that enough oil is present in the tear film that moisturises the eye. Lack of omega-3 fatty acids is associated with other ocular diseases such as macular degeneration and glaucoma. Omega-3 fatty acids that are important for health are mainly found in fish, whereas omega-6 fatty acids are found in nuts and vegetable oils. The daily recommended dose of DHA and EPA has not been agreed, but their relationship should be 1:1 and should account for about 3% of an adult’s caloric intake.

B-group vitamins

In case of eye diseases, eyes need B-group vitamins, such as B1, B2, B6, B9, and B12 in large quantities, but often at lower doses for individuals with glaucoma.

Mediterranean cuisine – fresh, ecologically grown produce, such as fruits and vegetables, olive oil, and legumes help to effectively improve eye health.

Which supplement would help keep your eyes healthy?

We suggest Pro Eyevision, which contains several bioactive and the most essential, cleanest and most absorbent substances, such as bioactive vitamin C L-ascorbyl-6-palmitate, zinc bisglycinate, selenomethionine, some of the most potent antioxidants, such as astaxanthin, zeaxanthin and several other necessary substances. Pro Eyevision is necessary for anyone working on a computer, or whose eyesight has begun to weaken, whose eyes are dry and sensitive, or who is starting to develop cataract or glaucoma.

NB! In summary, the main causes of eye diseases are:

inadequate nutrition – food that is low in nutrients;
stress – heavy and long-term negative emotions;
oxidative stress – environmental toxins, such as cigarette smoke and alcohol, pesticides and medicines;
light – excessive UV radiation and other radiation;
several diseases, such as diabetes, malfunctioning of the thyroid gland, and eye infections and injuries.
