Our eyes are together with the nose, the ears, the tongue and the skin to our sense organs. Thanks to our sense organs, we can perceive external stimuli. These are converted by the sensory organ into electrical impulses and transmitted to our brain. Our eyes enable us to perceive light stimuli. But what is good for the eyes and what harms them? We have put together for you the best known truths and errors around our eyes.
Reading at dusk damages the eyes
For our eyes, bad light is exhausting and it makes them tired faster when reading: Over time, the view becomes blurry and the letters are sometimes difficult to recognize. It may also be due to reading in bad light and headache.
Remedy can create your own bed. Because while sleeping, our eyes can recover. Although reading at dusk can have a short-term negative effect on our eyes, permanent damage from reading in dim light has not yet been proven.
Wearing glasses worsens the eyes
The eyes do not deteriorate just because you wear glasses. But especially for people who wear glasses for the first time, putting on the glasses can lead to the fact that one's own vision without glasses is perceived to be worse than in the past.
The reason for this lies in the previously missing possibility of comparison. Before buying the glasses, the intensity of vision for the person concerned represented the maximum in vision. However, wearing the glasses redefined the maximum vision. If the vision aid is discontinued, the maximum vision decreases as well. Thus, the patient becomes aware of the difference between the optimal vision and his natural vision.
Carrots are good for the eyes
"Carrots are good for the eyes", with this sentence parents try to make carrots tasty for their children. But is this statement true? What is certain is that carrots contain beta-carotene - a precursor of vitamin A. When fat is added to the body, it can be converted into beta-carotene vitamin A, which is why beta-carotene is also known as provitamin A. This is essential to the eyes, mainly for seeing in the dark.
Apart from carrots, other fruits and vegetables also contain beta carotene. These include apricots, honeydew melons, mangoes, broccoli, tomatoes or spinach. So if you eat a healthy and varied diet, you do not risk a lack of vitamin A. Additional vitamin A supplements are superfluous, because they do not make it possible to further increase your sight.
Sitting close to the television is bad for the eyes
Sitting too close to the TV in the long term has no negative consequences for the eyesight. However, sitting too close to the TV can cause eye burns or tired eyes at times.
So that the eyes are not stressed too much, the brightness in the room should be adapted to the screen. Incidentally, if children tend to sit very close to the television, a defective vision can be the cause. You should make an appointment with your child with the ophthalmologist and have the visual acuity checked.
The eyes can stop when they squint
Parents often admonish their children not to squint - supposedly could otherwise shut their eyes. However, it has not been proven to date that this case could actually occur. However, since strabismus can have a negative effect on the development of spatial vision, for example - if your child switches more frequently - you should consult an ophthalmologist.
