How do I improve your eyesight
Improving poor eyesight with eye training - is that possible?
Eye training cannot fix ametropia. Nevertheless, there are eye trainers that offer appropriate courses. Some even promise their customers that they will byconsistent training future do without glasses and contact lenses can. A closer look at the background to poor eyesight shows why this is not very reliable and when eye exercises can still help.
What is poor eyesight?
In the case of poor eyesight, sharp vision is not possible or only possible with visual aids. The most common visual impairments include nearsightedness and farsightedness as well as astigmatism and presbyopia. With these visual impairments, the image of the object to be seen does not hit the retina sharply, depending on the distance. Reasons for this include an eye that is too short or too long, an irregularly shaped cornea or impaired elasticity of the lens. On the other hand, weak eye muscles are usually not responsible for poor eyesight.
What can I do if I have poor eyesight?
If you have poor eyesight, an examination by an ophthalmologist is always recommended to find out the reason for the vision problems. If there is a simple ametropia, glasses or contact lenses can correct the poor eyesight. Sometimes laser treatment can also improve eyesight, so that those affected can do without a visual aid. However, training your eyesight cannot help.
Eye training for myopia
Myopia see blurred in the distance because their eyeballs are too long or the refractive power is too strong. To see in the distance, the ciliary muscle in the eye must be relaxed in order to reduce the refractive power of the lens. Eye training is supposed to provide greater relaxation of the ciliary muscle and thus improve myopia.
However, common eye examinations with a drug to completely relax the ciliary muscle show that this is of no use. This is because it does not happen that a nearsighted person suddenly sees sharply in the distance. Other training methods target the outer muscles of the eye, which are responsible for moving the eyeballs. To improve eyesight, eye training would need to strengthen the muscles so that they shorten the length of the eyeball. However, anatomically, this is not possible.
Eye training for farsightedness
Farsighted people mainly have problems with near vision because their eyes are too short or their refractive power is too low. In order to improve farsightedness, the training would have to lengthen the eye or make the lens more spherical by tensing the ciliary muscle.
When the ciliary muscle tenses, however, only the tension on the lens falls away and it just takes on its natural shape. But it cannot become more spherical than it is naturally. Their maximum refractive power is therefore limited. In addition, farsighted people are already using their ciliary muscles as much as they can. This more likely leads to overexertion of the eye muscles. Then targeted relaxation exercises can relieve the eyes, but they do not affect farsightedness per se and cannot improve eyesight over the long term.
Eye training for presbyopia
Eye exercises cannot protect anyone from presbyopia. Because it is not the eye muscles that become too weak, but the lens loses its elasticity. Under certain circumstances, the natural signs of aging of the lens can be delayed somewhat by a healthy lifestyle. This also includes giving the eyes enough variety and breaks. But special eye training is unnecessary.
What types of eye training are there?
Essentially, a distinction must be made between eye training to heal poor eyesight and relaxation exercises in the event of excessive stress. While the former is not scientifically tenable, relaxation exercises can be quite useful, for example when working with a computer for a long time. To do this, you only have to regularly look into the distance and consciously blink. This can also slow down the progression of myopia. However, this is not because training strengthens eye muscles, but rather because a trigger of myopia is avoided.
Can eye training be harmful?
For adults, eye training is usually at least not harmful if they continue to use the visual aids adapted by the ophthalmologist or optician in traffic and similar situations. In children, poorly corrected poor eyesight can prevent them from learning to see properly. Therefore, parents shouldn't just rely on eye exercises to improve eyesight. Instead, they should help their children wear visual aids as recommended by an ophthalmologist or optometrist.
