Wearing glasses makes your eyesight worse

Knowledge : True or false?

Does watching long TV damage the eyes?
"Child, your eyes are still very square!" Warned the parents when you spend a Sunday in front of the telly. As a child you already suspected that this was nonsense. And now the confirmation from the experts: "At least the eyesight does not deteriorate with long television viewing," assures Georg Eckert from the Association of Ophthalmologists. However, long, spellbound stare at the screen - the ophthalmologist speaks of gaze monotony - can irritate the eyes. Because if you watch TV, you blink less often and barely let your eyes wander. The result: the tear film of the eye is only poorly distributed, the eye becomes dry and the conjunctiva is irritated. To do this, however, you have to watch TV extensively or suffer from dry eyes. Children and grown-ups can take a deep breath, Sunday is saved!

Does long reading promote myopia?
Right! While nearsightedness was almost unknown among the Inuit in Greenland and North America until they were literate, ten to 20 percent more people in Japan suffer from nearsightedness than in Europe - researchers explain this primarily with the changed environment in which reading books and working on the computer takes up more and more time. The constant "close work", in which the eyes focus on a short distance, promotes the elongation of the eyeball. This means that the refractive power of the eye lens focuses on a short distance even in the relaxed state. In order to be able to see better in the distance, myopic people often squeeze their eyelids together - the lens becomes more curved and the distance vision is increased. The ancient Greeks recognized this, because the medical term for nearsightedness is myopia - "closed eyes".

Does smoking harm the eye?
Nicotine narrows blood vessels and increases the risk of having a heart attack, stroke, or leg infarction. But the eyesight also suffers from the poor blood supply. Smoking is the most important lifestyle-related risk factor for macular degeneration (see page 25).

Do sunglasses protect eyesight?
Yes, sunglasses block parts of sunlight that are harmful to the eyes - ultraviolet radiation (UV). In this way, they protect the retina from damage and macular degeneration in old age. "In Berlin, however, the UV dose is too low, even in midsummer, to really damage the eye," explains Eckert. So dark glasses are just a fashion accessory here. It is different in the mountains. The most important natural UV protection is the ozone layer, which is much thinner than in the capital because of the alpine height. Alpinists and skiers are therefore well advised to wear sunglasses with adequate UV protection. When buying, you should pay attention to the »UV 400« seal. However, such seals are easy to forge - so the sun protection should be purchased from a trusted dealer or checked there.

Does reading harm in poor light?
Many people like to relax and read a book in the evening in the dim light. But browsing in the dim light is said to spoil the eyes. "This is a myth," says ophthalmologist Eckert. Although the eyes tire more quickly in poor light, reading in the evening does not lead to permanent visual damage. "However, the eye can compensate for an existing ametropia in the dark less than in the light," says Eckert. This can lead to headaches and burning eyes.

Do your eyes get worse if you don't wear glasses when you need them?
Glasses can be a matter of taste. Anyone who thinks they are too pretty for the two glasses on their nose, although they have to guess their beauty in the mirror, can rest assured - it is a myth! Those who do not wear glasses despite their ametropia will not get worse eyes. "It's like not putting on shoes - your feet don't get any worse," warned Georg Eckert from the Association of Ophthalmologists. Even a visual aid with the wrong number of diopters does not ruin the eyes. "At most, those who wear glasses get a headache from it."

Do your eyes get worse when you wear glasses?
The good news: "No, it doesn't matter to the eyes whether you wear glasses," says Eckert. Eyesight does not deteriorate or improve. It does not matter which ametropia the person concerned suffers from. In addition, you can see more clearly with glasses. The bad news: your eyes get worse on their own. Guilt is once again our time, which is running out inexorably. "In the course of life, the eye lens becomes more and more inelastic," says Eckert. This makes it more and more difficult for the eye to focus - time for new glasses.

Is Carrot Juice Really Good For Eyesight?
Right! The carotenoids contained in carrots and other vegetables, especially red and orange, can prevent retinal diseases such as macular degeneration (see page 25). Researchers suspect that the carotenoid lutein protects the eye from the formation of harmful oxygen radicals by intercepting UV radiation in front of the retina and converting it into heat. Lutein works like an inner pair of sunglasses. For a healthy, lutein-rich diet, ophthalmologist Eckert recommends a Mediterranean diet, i.e. fish several times a week, little meat and sausage, but plenty of fruit and vegetables and unsaturated vegetable oils. A healthy diet does not make the eyes better - but it doesn’t make them worse either.
