“Folk” methods of restoration of vision
Fearing any medical intervention, many people resort to the so-called folk methods. Since Soviet times, a stereotype has taken root in our society that carrots are good for the eyes. due to the supposedly high content of vitamin A. Indeed, this element helps the retina to function and, among other things, see better in low light conditions. However, its deficit must be very large in order to have any negative impact on the ability to see in general. And in the opposite direction, it does not work: treating vision problems by eating carrots will not bring results. The same goes for blueberries, other berries, vegetables and fruits. Yes, they are useful. But no biologically active additives and phytopreparations have a healing effect.
Glasses and lenses. traditional solution with nuances
Vision problems can be corrected with glasses or contact lenses. Unlike “folk” methods. they really work. But let’s understand what glasses and lenses are.
We have already mentioned that glasses were invented back in the Middle Ages. Contact lenses. also not the latest technology. They appeared in 1960, when the Czech scientist Otto Wichterle invented a method for treating a hydrophilic polymer. This substance had the ability to absorb water and, after being saturated with water, it became very elastic. like the cornea itself.
Today’s glasses and lenses. unlike those “optical prostheses” that were available at the end of the 20th century. However, both of these options did not get rid of significant drawbacks:
- glasses can simply be lost or broken;
- they require constant care, special storage and cleaning procedures;
- when the temperature drops, the glasses fog up;
- even the best glasses distort the shape of objects, which means that vision in them will not be entirely natural;
- in turn, wearing lenses often leads to conjunctivitis, even if the rules of hygiene are observed;
- in addition, in the context of the coronavirus pandemic, doctors do not recommend the use of contact lenses, since this virus is transmitted precisely through the mucous membranes.
How to improve your eyesight in 1 day?
Human eyes. the main channel for obtaining information about the world around. Unfortunately, it is not uncommon for vision to deteriorate. Therefore, attempts to improve it have been made by people since ancient times: first with the help of various berries, herbal decoctions, magic rituals, then with the help of glasses, the first of which were invented in the 13th century in Italy, and today. using the most advanced technology, for example. laser correction. Which of the existing approaches is the most effective and safe, we will analyze in this article.
How eyes work and why we see worse?
First you need to understand how human eyes work. The process starts from the cornea. it is the first “lens” of our sophisticated optical system. A ray of light hits it through the pupil, which can be compared to the diaphragm of a camera. The integrity of the cornea is important for a clear image. If the surface is uneven, the image enters the brain like a video from a scratched camera. The cornea is covered with a very thin layer of tears. Any impact that disrupts this tear film can lead to destruction of the corneal surface, and as a result. eyesight will get worse.

Further behind the cornea is the lens. second lens of the eye. Its shape changes to focus with a special muscle. Further, the vitreous body occupies almost the entire cavity of the eye up to the retina. our image receiver. This, in turn, is a kind of screen on which a picture is formed, passing through the cornea, lens and vitreous body.
When all these components work together, we see clearly. If it is violated, the picture is distorted, and, accordingly, vision becomes worse. Such changes can occur at any age under the influence of various factors. But today it is easily fixable.
Laser correction: myths and facts
Today, laser vision correction is one of the most modern methods of vision correction. From a medical point of view, this is a surgical procedure, but it takes place without a scalpel. the procedure is performed with a laser. Laser vision correction surgeries have been successfully carried out since 1985.
Communicating with patients, we have identified the most common fears, because of which many do not dare to undergo the procedure. And below we will debunk these stereotypes.
Many patients worry that laser correction can be dangerous precisely because of the effect of the beam itself. However, its power, diameter and other parameters are calculated so accurately that the beam has exactly the effect for which it is intended.
- It’s a painful procedure?
The procedure takes place under local drip anesthesia. You may feel a little discomfort, however, it feels like a normal touch, without any pain.
- For the procedure, you need to go to the hospital?
The procedure itself is fast. all manipulations take 10-15 minutes. And the very effect of the beam on the eye lasts 30-40 seconds. After the correction, the doctor makes a control examination and lets the patient go home.
- After the procedure, I will not see for two weeks?
We do not know where this misconception came from, but the huge advantage of laser vision correction is that after the operation, the very next day you can read, write, use gadgets and even take a selfie.

- Is it possible to perform the procedure for pregnant and breastfeeding women?
Pregnancy is a contraindication to laser correction, since the woman’s body undergoes a number of changes, the hormonal background differs from the usual. Therefore, the result of vision correction may not be stable. The same goes for the lactation period. But it is possible to carry out the operation before pregnancy and after childbirth.
What not to do after the procedure. so it is to visit the pool, bathhouse, sauna, swim in ponds and use cosmetics for several days.
In any case, before the laser correction, you will be examined by a doctor who will give all the necessary recommendations and tell you about all aspects of the treatment.
