Healthy eyes in a digital age
To keep the eyes healthy and to prevent the degeneration of the eye, healthy food is very important!
It is a natural process for the eyes to deteriorate in old age. We must accept this and cannot prevent it.
Nowadays, however, many more people have eye problems at a younger age. There are several possible reasons for this. Simply because people don’t watch what they eat, too many people don’t follow healthy diet guidelines. Another reason is that nowadays the eyes are more heavily burdened by the amount of screen time such as TVs, tablets, telephones and computers.
Eye problems due to screens
It may sound familiar, you have been watching TV or sat in front of the computer or other screen for too long and you experience blurred vision, headache, burning eyes, concentration problems or a disturbed night’s sleep. We call this digital fatigue. The longer you sit in front of a screen, the worse the symptoms can become. This is becoming a major problem nowadays; if you are not sitting in front of the TV or computer, you are looking at a telephone or tablet. We see that these eye complaints increase strongly due to digital fatigue. This is a major problem, especially among young people.
It has been proven that we blink less when we look at a screen. Blinking keeps your eyes moist and less blinking makes that your eyes become dry and irritated.
We are also often too close to the screen. This is very strenuous and tough on the eyes. According to research, the blue light from the screen can lead to various eye conditions.
‘If we look at something up close, it is presented differently on our retina than something that can be seen in the distance. If something is close, the eye must make an effort, the lens becomes rounder to be able to project it sharply. The eye doesn’t like this. If a child frequently looks at things up close at a young age, the eye is given the signal to become longer. The tissue in the eye must then spread over a larger area. Later in life, problems arise at the back of the eye, such as the disappearance of the retina or bleeding. This indicates how seriously the problem should be taken!
Myopia was something you used to have because it was in your DNA, nowadays many people/young people have become myopic by sitting too much and too close in front of a screen. The numbers don’t lie, the number of myopia cases is rising enormously!
How do we keep our eyes healthy?
It is very important not to sit too long and not too close to a screen. Take a break from time to time, look outside or walk around. Make sure there is enough light in the room where you are and consciously blink more with your eyes. Parents will have to watch that children do not spend too much time behind the TV, tablet, telephone, etc., but rather play outside. This benefits eye health at a later age! Naturally, healthy food is also important. The eyes are more strained, so they need the right nutrients to stay healthy. This can be done by paying close attention to your diet or by adding the right dietary supplements to your diet.
A healthy diet is important!
A healthy lifestyle is very important. The eyes need the right nutrients to stay healthy or to recover. If the eye is already quite damaged, it is difficult to repair. However, it is never too late to switch to the right diet. By taking the right food and/or supplements, the body gets the nutrients it needs. Recovery requires patience, but you will be amazed by what the body can do with the right building blocks. It is important to prevent damage by getting the right nutrients in time. If there are eye problems, it is even more important to immediately switch to the right diet. We have listed nutrients important to the eye below.
Vitamin A plays an important role in cell renewal. Vitamin A also ensures that the eyes can adjust well in less light, so vitamin A is very important to prevent night blindness.
It is important that not too much Vitamin A is ingested. Between 800 and 1000 mg per day is the maximum for an adult. Larger quantities are harmful to the eye.
Vitamin B2 is important for the oxygen supply in and around the eye and helps to maintain clear vision.
Vitamin C & E:
Vitamin C & E are both strong antioxidants. (Antioxidants protect your cells against damage from free radicals). Vitamin C helps protect the eye against harmful UV light and Vitamin E helps to keep vision healthy.
Zinc is important for the absorption of Vitamin A. It also supports the condition of the eye, ensures that you can continue to see clearly and keeps the retina healthy.
Omega-3 fatty acids (mainly DHA) are very important for eye health. They protect the retina and prevent the development of dry eyes. (We will elaborate on this on our ‘Omega-3’ information page)
Lutein & Zeaxanthin:
The yellow spot (macula) can be found in the centre of the retina. This ensures sharp eyesight and being able to see colours. The most important components of the yellow spot are the carotenoids lutein and zeaxanthin. These filter the blue light and ensure the health of the macula. Lutein is mainly found on the edge of the yellow spot and zeaxanthin is located more in the centre. Both carotenoids protect the eye against oxidative stress and therefore reduce the risk of cataract and age-related macular degeneration. They are not produced by the human body and their concentration in the retina depends on food intake.
Goji berry, the most powerful superfood for the eyes!
Goji berries are very good for healthy eyesight, they contain many antioxidants, vitamins and minerals. The fruit contains beta-carotene, zinc, the antioxidants lutein, zeaxanthin and vitamins A, C and E. (We will elaborate on this on our other information page ‘Goji Berry’).
Nutrition and eye diseases
Research has shown that the right nutrients can prevent or delay eye diseases such as macular degeneration. Macular degeneration occurs when the yellow spot in the retina contains too few pigments. Our body cannot produce these pigments itself and is therefore dependent on food. These pigments protect the retina. Without these pigments, the retina is damaged, causing visual impairment. We have already discussed above which nutrients are important to the eye. Most people do not manage to get enough of these substances through food, but if you do, you decrease the risk of age-related macular degeneration. On our other information pages, we look into more detail at various eye diseases.
Nutritional supplements for healthy eyes!
So, it is clear that many people do not pay attention to their diet, we are too busy, or it requires too much effort. The eyes are also more strained because almost everyone sits in front of a screen every day, whether this is a TV, telephone, tablet or computer. All this is the cause of eye problems occurring much more often and at a younger age. In order to prevent eye problems later in life or to limit current symptoms, it is now more important than ever to pay close attention to nutrition.
Although the above nutrients can all be obtained from food, many people opt for nutritional supplements. Provided you choose the right supplements, it is certain that you will receive the right nutrients the eye needs every day. And without having to watch what you eat every day. Or it provides that little bit extra in addition to a healthy diet! Make sure that not too many of these nutrients are ingested, that wouldn’t be good neither, especially in case of Vitamin A.
We fully support the idea of a healthy lifestyle and supplementing the diet with the right nutritional supplements. That is why we have launched self-developed nutritional supplements, which we believe are all the eye needs. Want to know more? Take a look at our homepage for our unique supplements.
