Worldwide, more and more people are affected by low vision, but you can also take precautions against low vision. Visual defects are for example nearsightedness, farsightedness, presbyopia and so on. All visual impairments, as the name suggests, lead to poorer vision. There are various reasons for the declining ability to see, for example UV light, smoking, increasing age or an unbalanced, unhealthy diet.
The good thing is that vision can often be improved with little effort and visual defects can be reduced. Vitamins for the eyes and a balanced diet with plenty of fruits and vegetables are the secret recipe for good vision. If you already suffer from a visual impairment, we advise you to undergo laser eye surgery at our laser eye center in Leonberg.
Of course, it is possible to temporarily correct a visual defect of the eyes with glasses or contact lenses. It should be said, however, that aids such as eyeglasses or even contact lenses are only temporarily effective against visual impairment. This means that if your dioptric values of the visual defect change, new glasses or new contact lenses against the visual defect are also necessary.
In the case of poor vision of the eyes, due to a change in the structure of the eye, the incident light no longer hits the retina properly. Depending on the type of visual impairment, it is no longer possible to see sharply. Distant or near objects can no longer be seen clearly with the naked eye due to impaired vision. Glasses or contact lenses can help to compensate for such visual defects.
Slags: bad for the eyes
The eye is in constant exchange with the body even in the case of poor vision and is supplied with blood like all other organs. Nutrients and vitamins also get into the eyes. If the diet is not balanced enough or is characterized by unhealthy food, an excessively high dose of waste products comes to the eye along with the nutrients, which can lead to impaired vision. Slags are waste products that are produced during daily metabolism and can lead to impaired vision. Normally, they are excreted from the body, but in large quantities the intestines, liver and kidneys are overwhelmed.
The excess waste products are eventually deposited in the eyes, lens, retina and eye muscles. A visual impairment can develop. As a result, vision deteriorates and visual impairment can occur. One should therefore not only pay attention to a balanced diet, but also to a vitamin-containing diet in order to prevent visual impairment. Important vitamins for the eyes are for example vitamin C, vitamin A, vitamin E and vitamin B2 can prevent a visual impairment. Glasses and contact lenses can help to compensate for a visual impairment, but only temporarily.
Selenium and zinc, as well as the carotenoids lutein and zeaxanthin, can also be included more often in your diet to help counteract poor eyesight. Vitamins that are good for the eye are often found in various fruits and vegetables. Spinach, tomatoes, broccoli, mangos and carrots contain a lot of beta-carotene, which the body converts into vitamin A and helps the eye not to develop a visual defect. Spinach – and other green vegetables such as kale and peas – also contain lutein and zeaxanthin. Citrus fruits help the eyes against it with vitamins C and B. They can help the eye to prevent vision loss.
What is a visual defect?
A visual impairment is understood as an impairment of vision. There are various visual impairments that can be distinguished:
- Myopia
- Long-sightedness / astigmatism
In the case of short-sightedness and long-sightedness, the eye is shaped differently than in people without short-sightedness. Such visual defects as nearsightedness, farsightedness and astigmatism are diagnosed and treated by ophthalmologists or opticians. Glasses or contact lenses are temporary solutions, but after some time they need to be replaced. If you want to permanently correct a visual defect such as nearsightedness, farsightedness or astigmatism, laser treatment of the eyes is recommended.
Pay attention to different vitamins for the eyes
Since different trace elements and vitamins have different effects on the eyes, it is not enough to consume only certain types of vitamins. Instead, the variety of vitamins is important for healthy eyes, which can be obtained with a balanced, varied diet and prevent vision loss.
Vitamin A, for example, helps against night blindness and visual impairment of the eyes and vitamins B2, C and E protect against cell damage. The trace elements selenium and zinc are also directly involved in vision. Carotenoids such as lutein and zeaxanthin protect against harmful blue light. In addition, almost all of these trace elements and vitamins for the eyes have an antioxidant effect. The more different vitamins a person takes in for the eye, the more he supports the performance of his eyes and thus his own vision. The susceptibility to visual impairment decreases.
Protects nutrition completely from visual impairment of the eyes?
When talking about nutrition and vision problems, it is important to mention that a healthy and balanced diet is important for healthy eyes, but it does not always protect you from developing vision problems. By a visual impairment one understands mostly a long-sightedness or also short-sightedness. Therefore, you should visit an optician or ophthalmologist at least once a year. Regular control and monitoring of your eyes is the best protection against visual defects such as nearsightedness or farsightedness. An optician or ophthalmologist can observe and detect even the smallest changes in the eye. The ophthalmologist can help you immediately and act early enough, should you experience vision problems.
In addition, nutrition, no matter how good it is, cannot prevent visual impairments such as: Cataract (cataract), glaucoma protect. These visual impairments are clouding of the lens that makes it very difficult to see with the naked eye. From the age of 40. It is advisable not to miss the annual appointment with the ophthalmologist or optician due to such eye diseases and visual defects.
Is it possible to prevent macular degeneration (AMD) with vitamins??
Especially in old age, vitamins play an important role for the eyes and potential visual impairments, because they support the functionality of the macula and such visual impairments occur less frequently. The macula is the place on the retina where focused light collects and only when it is intact can a person see well with their eyes. However, since most light, and thus also the highest proportion of harmful blue light, hits the macula, it loses parts of its functionality in the course of life. A visual impairment can be the consequence for the eye.
In addition, especially in old age, the carotenoids lutein and zeaxanthin, which are important for the macula, decrease in concentration, which increases the natural wear and tear of the macula even more. One speaks then of an age-related macular degeneration (AMD).
Here too, however, a balanced supply of nutrients and vitamins for the eyes helps. Especially green vegetables with lutein and zeaxanthin are good, because the carotenoids filter the harmful blue light. However, regardless of your vitamin intake, you should consult an ophthalmologist as soon as possible if you notice any signs of macular degeneration (AMD).
As soon as macular degeneration (AMD) – or other visual impairments such as nearsightedness/farsightedness – is in an advanced stage of development, unfortunately vitamins for the eyes can no longer help. To prevent or reduce vision problems, the right vitamins for the eyes are a good remedy in any case. And also the rest of the body is happy about the nutrients to be armed against a visual impairment.
Can diet stop the so-called flying mosquitoes?
The Moches Volantes are also known as flying gnats. These flying mosquitoes express themselves as small shadows, respectively. irregular lines in vision. The trigger here is a clouding of the vitreous body in the eye. A healthy diet can keep such ailments from occurring, but is no guarantee that you will never be affected by them.
Therefore, the appointment with the ophthalmologist or optician should be made once a year. This can immediately perceive and interpret any changes in the eye and vision. It is possible for the ophthalmologist and optician to initiate ways to correct the problem.
Am I nearsighted or farsighted?
Myopia is a visual defect that makes it almost impossible for the naked eye to see distant things sharply. Here the incident light is concentrated too strongly by the lens of the eye. Therefore, the light does not bounce on the retina, but is concentrated just before the retina.
Farsightedness is a visual defect in which close objects are difficult for the eye to focus on. The lens does not refract the light strongly enough and it does not focus on the retina but behind it. The light on the retina is not a point, but arrives as an area.
Glasses and contact lenses can help to compensate for such visual defects. The lens is simulated and allows the light to fall properly on the retina.
For which visual defects glasses and contact lenses help?
Glasses and contact lenses do not help with every visual defect. However, glasses and contact lenses help with vision problems such as: Nearsightedness, farsightedness or astigmatism. Other visual defects such as cataracts and glaucoma cannot be corrected. This visual impairment affects the eye in a different way. Only an operation or, as in the case of glaucoma, treatment with medication can help.
However, when it comes to farsightedness, nearsightedness and astigmatism, the optician or ophthalmologist can help with glasses or contact lenses. These compensate for the curvature of the lens in the eye and make it possible to see clearly again. Here it should be added, however, that the number of dioptres can change. This also requires new glasses or contact lenses.
What helps permanently against a visual impairment?
To combat a visual defect such as myopia or hyperopia, glasses or contact lenses are only a temporary solution. To be permanently freed from nearsightedness or farsightedness, it is advisable to have the eyes lasered. We will be happy to inform you about this in a personal consultation.
