Can be cured long-sighted and short-sighted
Nowadays, a lot of people spend the entire day in front of screens. As soon as you wake up, you pick up your smartphone, call up the messages on the way to work, and then spend 8 hours in the office in front of a monitor.
As a result, the shape of the eyeball changes over time and it adapts to this close-up mode. The consequence of this is myopia.
Nearsightedness, also known as myopia, is a widespread weakness in visual acuity, which manifests itself as poorer recognition of distant objects. The symptoms usually appear during puberty and become clear, for example, at school through the blurred perception of the blackboard. For example, one of the consequences that myopia sufferers often suffer from is headaches.
You can determine whether you have myopia with an eye test at the ophthalmologist or optician. The diopters can also be determined here.
The diopter is a unit of measurement for the strength with which a spectacle lens refracts light. At the same time, it characterizes the ametropia of the eye. Myopia is indicated by minus values and farsightedness by plus values. The higher the diopter, the stronger the refractive power of the spectacle lens and thus the ametropia of the eye.
More about myopia
What is myopia?
There are two causes of severe myopia. Either the eyeball is too long or the lens causes the light to refract incorrectly so that it is focused in front of the retina.
In both cases of myopia, the focus of the refracted light beam that enters the eye through the pupil is not optimally on the retina in the back of the eyeball, but rather clearly in front of it. This makes objects appear farther away and blurry. Those affected are often forced to wear glasses.
In around 80 percent of cases, genetic factors cause myopia to develop. Initial difficulties in adapting the visual acuity in the distance can usually be noticed from the age of ten. This process worsens until around the age of 25.
What are the symptoms of nearsightedness?
The eyes of nearsighted people only perceive objects in the distance in a blurred manner. This type of poor eyesight is often noticeable at school, at work or in traffic. The words on the blackboard or the street names on the signs can no longer be seen clearly and precisely as usual.
An eye doctor or optician can determine ametropia, such as nearsightedness or farsightedness, with an eye test. He can also determine diopters. This test is carried out with the help of a refraction measuring device, whereby the refractive power of the eye is determined and the diopter is calculated. Myopia is indicated by minus values and hyperopia by plus values.
By identifying the values, it is possible to evaluate which measures could be taken to restore vision. The use of glasses or contact lenses is often recommended to compensate for the deteriorated refractive power of the eye.
What are the causes of myopia?
Myopia is a phenomenon that can affect anyone. The causes are sometimes difficult to classify.
In most cases, genetic disposition plays a role. Myopia is therefore a type of ametropia that often occurs at a young age.
The first symptoms of nearsightedness often appear in children between the ages of ten and twelve, and the poor eyesight can worsen by around the end of their twenties.
People who have a genetic disposition for nearsightedness usually show the diopter strengths of their parents after the age of 25. These usually remain constant well into old age.
Presbyopia rarely has anything to do with a genetic predisposition.
- Often genetic
- Often occurs in childhood
- From the late twenties, there is usually no further deterioration
How can myopia be treated?
There is no cure for the genetic causes of myopia, but corrections can be made.
Aids such as glasses or contact lenses can enable full vision while wearing. However, they do not fundamentally improve the eyesight.
Myopia can be cured with laser surgery or lens replacement. Nowadays, these procedures open up a completely new world for patients suffering from myopia, in which visual aids such as glasses or contact lenses can be permanently dispensed with.
Interventions using lasers offer medical care at the highest level and can be carried out with a negligible risk.
A permanent improvement in the refractive power can only be achieved by laser treatment or by replacing the lens.
What can you do about myopia?
Improvement in myopia
- Children should spend a lot of time outdoors
- Eyewear wearers should give their eyes a break
- Regular eye test to check
You cannot generally prevent ametropia, which also includes nearsightedness, and only correct it through surgical measures.
Yet scientific studies show that parenting affects their children's eyesight.
Research on myopia in children shows that children who have spent a lot of time outdoors are less likely to have myopia.
For this and other health reasons, it is essential in childhood and adolescence to spend a lot of time outdoors and to focus on objects that are further away in daylight. This can prevent myopia.
If you wear glasses or contact lenses, it is advisable to give your eyes a break from time to time. Although the eyes are relieved by wearing a visual aid, there is a risk that they will deteriorate in the long term as you get used to the aid.
Regular visits to the ophthalmologist can help improve myopia. Your doctor can give you competent information about your eyes, their condition and your cornea. He can also inform you about further treatment options.
