Man is born to see the world in all its colors. Vision is an invaluable gift, through which we orient ourselves in the environment, learn to learn new things. The opportunity to see opens up to us a huge potential for obtaining various kinds of information. Folk wisdom says: "It is better to see once ..."
Methods of vision correction
Over the years, you have to strain your eyes more often to easily distinguish individual objects or to focus a clear "picture". A large part of the adult population of the planet suffers from various types of refractive disorders. Modern ophthalmology has a whole arsenal of methods aimed at how to correct vision.
Eye surgery
One of the first methods of correction of visual impairment is the operation of keratectomy. She gained great fame in the world thanks to the scientific development of academician SN. Fedorov. Optical pathologies of the eye were corrected by surface incisions on the cornea with the help of special microsurgical instruments. At that time, this method produced high results, but had significant shortcomings in the form of postoperative complications.
In modern refractive surgery, intraocular minimally invasive surgery is performed in cases of very high degree of visual impairment, when laser correction is considered to be inappropriate. If a patient is diagnosed with serious eye diseases that require a radical treatment, then surgery is performed on the cornea using a transplant.
Laser vision correction
This method is certainly the most progressive and effective in the field of ophthalmology. It allows you to modify the shape of the patient's cornea with any kind of refractive pathology, using an excimer laser. The main advantage of this procedure is its accuracy, reliability and efficiency. The principle of operation of this technique is quite simple:
- A directional laser beam removes the upper layer of the cornea, forming a kind of shred.
- Further, the thickness of the cornea itself is modified to improve its refractive ability.
- The final stage of the operation involves the installation of the first shred of the former place.
After correction of vision by laser surgery, the patient can immediately evaluate its effectiveness. It is performed on an outpatient basis, lasts about 20 minutes and does not require a long recovery process. Modern ophthalmological centers use several types of laser surgery:
- PRK or photorefractive keratectomy;
- LASIK technology and its more modern varieties.
Contact vision correction
This method is most suitable for patients who are contraindicated in surgical intervention. They successfully use lens correcting eyesight, which are made of soft material. The largest companies with a world name annually produce a huge amount of various products for the contact market correction for myopia, hyperopia or astigmatism on the consumer market.
You can choose one-day, moisturizing or lenses for prolonged wearing. These items are not only able to improve eyesight, but also help to lead a habitual way of life. They are thin (up to 1 mm) and completely not perceptible in the eyes. Do not break and do not break like in the case of glasses, and look aesthetically. Contact lenses are prescribed to patients after surgery for the elimination of strabismus.
How to correct vision at home?
Unfortunately, contact lenses or glasses can not completely cure eye pathology. These remedies are original prostheses that simply help to function in a weakened organ. Even a laser operation does not always give a 100% result. The restoration of vision is important to do on your own, with a lot of effort and work. Only determination and perseverance will make it possible to improve the condition of the eyes.
The best thing for vision correction at home is to follow a diet in which you need to include products that help maintain your vision, as well as applying different techniques and performing special exercises for the eyes. To fight with refractive anomalies should be started as soon as possible - this will help reduce the progression of the disease.
How to correct vision with myopia?
A person suffering from myopia can not clearly see objects that are far away from him. This type of pathology of refraction has an innate or acquired etiology, and affects most of the world's population. To treat myopia, doctors use different methods. Optical correction of this pathology is one of the most common techniques and consists of the use of glasses, contact and orthokeratol lenses.
With the help of the latter, a night vision correction is performed, which is a novelty in the field of ophthalmology. Refractive therapy consists of using special night lenses, which the patient takes after sleep and does not need eyeglasses for the next day. Thanks to this method, the process of myopia progression can be stopped.
How to correct sight at farsightedness?
Patients with this type of pathology lose the ability to clearly distinguish objects, both from a near and a long distance. Hypermetropia is a common cause of reduced visual acuity in people after 45 years of age. The methods of treatment for this disease do not differ from those described above. The difference is only in determining the ultimate goal - the ability to transfer the image of a focused object from the area behind the eye to the retina. It is achieved surgically or non-surgically. However, it should be remembered that eyes after vision correction require special care and training.
Can I correct my vision with exercises?
While at home, you can try to improve your eyesight with the help of special exercises. They help relieve tension and accelerate the process of restoring normal refraction and accommodation. The main purpose of this training is to "pump up" the weak muscles of the eyes. It does not take much time, but it is quite effective. Perform each exercise should be 7-8 times. After the end of the workout, relax your eyes, covering them with warm hands.
Here, what exercises to improve vision are recommended by specialists:
- Slowly move your eyes, lifting them up, and then lowering down.
- Keep your head straight. In this position, move your eyes to the left and to the right.
- For about a minute, blink your eyes rhythmically.
- "Draw" an imaginary square, and then a horizontal eight or imagine the dial on the clock, "count" your eyes every hour in a circle.
Is it possible to correct vision with glasses?
Glasses for vision correction are the most convenient and affordable method. This useful accessory helps to eliminate all types of refractive anomaly. Its main function is to accurately focus the visual image on the retina of the eye. Ophthalmologists recommend wearing glasses at a high degree of myopia, hyperopia or astigmatism .
Ocular correction is considered a good alternative for those patients who are contraindicated in all types of surgical intervention. But lenses for glasses are selected by a doctor strictly individually, so without the help of an ophthalmologist, in this case it will not work out. In addition, one of the drawbacks of this type of vision correction is its local appearance (limiting side vision).
