Every person wants to have sharp vision and easily distinguish objects located at different distances. But regular lack of sleep, constant stress, and long periods of work on a PC take their toll. All these factors negatively affect the visual system. How to help tired eyes? In addition to corrective optics, special training glasses are gaining great popularity. But not everyone understands how to use them correctly. Let's figure out together whether there is any effect from such products and how they work.
Perforation glasses
Hole glasses to improve vision have a plastic or metal frame into which opaque lenses are inserted. The eyepieces are made of dark plastic and have a large number of microscopic holes. They are arranged in a certain sequence - pseudo-chess.
Perforation glasses have an effect similar to a stenope or a pinhole camera. The second is a lightproof box with a small hole on one side and a monitor on the opposite. The role of the screen is performed by frosted glass or white paper. A stenope in appearance resembles a regular camera, but without a lens. Instead there is a small hole.
The perforated trainer is also equipped with microscopic holes that reduce the degree of light dispersion onto the mesh shell. This increases the clarity of the resulting image.
Operating principle
The holes in the plates that replace lenses are not entirely simple - they can be conical or cylindrical. Which one will be more convenient for you can be found out experimentally. The principle of operation of these vision simulators is similar to that of a pinhole camera: when looking at objects through small holes, the depth of field increases, and the image falls on a fragment of the retina that has better sharpness. In addition, training glasses help to properly distribute the load on the eye muscles, which reduces eye fatigue and gives a feeling of psychological comfort.
What is the operating principle?
Training glasses allow you to load the weakened muscles of the organ of vision and remove the “extra burden” from overstrained muscles. This leads to a significant increase in eye sharpness, since tension is relieved from them without visible effort.
The operating principle of training optics is based on the anatomy of the visual apparatus and the physical laws of redistribution of light fluxes. If the eye muscles do not work correctly, the thickness of the lens is adjusted, which leads to refractive problems.
The clear image that a person with a healthy organ of vision receives is formed by the lens. This element performs the functions of a lens located on the retina of the eye. As a result of muscle overstrain, there is a displacement of the image of the object and its discrepancy with the retina. As a result, the patient develops myopia, hypermetropia or astigmatism.
| To correct such pathologies, ophthalmologists usually prescribe wearing corrective optics (contact lenses, glasses). At the same time, the simulator can not easily “mask” a deviation in refraction, but actually help restore visual acuity. |

Terms of use
It is recommended to use training glasses for half an hour to two hours a day, then they need to be removed. You can do normal household chores in them: cook, read, play with children. When wearing glasses, the gaze should not be focused at one point, but should constantly move between different objects and details, then the effect of the simulator becomes noticeable. The glasses can even be worn as sunglasses in good weather. In combination with training, it is very useful to take vitamins and do visual exercises. Often a person spoils his eyesight only because of his own careless attitude towards eye health. Training glasses will help take care of them, improve visual acuity and reduce fatigue of the eye muscles.
Types of glasses with holes. Tips for choosing
The product can have two shapes: conical and cylindrical. It is impossible to say which model is better. You need to try on both options and evaluate how comfortable you feel in them. The frame is always made of metal or plastic. In stores you can find glasses for men, women, children and the elderly.
Judging by the reviews, the Fedorov simulator is considered the most convenient. It is comfortable to walk in it, look, i.e. lead a normal lifestyle. If you plan to wear them outside to protect your eyes from the sun's bright rays, make sure the product fits snugly against your face.
The operating principle of all models is identical. The only difference is the frame size.
Advantages and disadvantages
Glasses with holes provide temporary vision improvement. If you stop using them on a regular basis, your refractive problems will return. So the statement that the simulator is capable of eliminating ophthalmic disease once and for all is nothing more than a smart marketing ploy. The product cannot be classified as a therapeutic agent.
| Their main value lies in preventing the development of diseases. Daily use of perforation glasses can block further decline in visual acuity. |
Those who do not suffer from refractive errors can also wear optics. Because the product is good at relieving fatigue and overstrain from the organ of vision. The glasses are absolutely safe and do not pose a threat to health. In addition, they do not aggravate existing vision problems, unlike conventional corrective products.
The duration of use is specified in the instructions, but you can wear them longer than the indicated period. Since there is no harm, then it is allowed to break the rules a little. Plates inserted into the frame reduce the amount of sunlight penetrating the mesh shell. For this reason, it is uncomfortable to be in exercise equipment for a long time, especially in low light conditions.
Glasses with holes require an adaptation period. In the first days, a person feels some kind of obstruction in front of the organ of vision, discomfort due to decreased lighting. However, if you wear the product on a regular basis, the negative effects will quickly pass. Return to contents
Glasses eye trainers Instructions for use
There are several very important rules for using training glasses. They are necessary for the most comfortable treatment, as well as getting used to the glasses.
1. It should be remembered that at first the sensations and vision will be unusual. Don't worry, you'll soon get used to it and perceive the world around you absolutely normally through the perforation glasses. You should also be prepared for the fact that through glasses you will see more clearly and sharply.
2. Wearing glasses should be started gradually. 5-15 minutes will be enough at first. For a more comfortable adaptation, you should put on glasses for 5–15 minutes 3–4 times a day. This will help you get used to this procedure gently and painlessly. If you feel discomfort, you should take off your glasses and rest, and put them on again after 1.5 or 2 hours. It will take from one and a half to two weeks before you fully adapt and wearing glasses becomes comfortable for you. The course of treatment lasts about a year. But it depends on your disease.
3. Before completing the course of treatment, you should gradually reduce the time you wear glasses. To avoid stress to your eyes. Both the beginning and the end of treatment should be gentle and gradual. To avoid stress.
4. It is important to remember regularity. If you wear glasses only occasionally, there will be no effect. It is best to keep a calendar to monitor the regularity of your activities. Such a calendar should be placed in an accessible place, which in itself will serve as a reminder for you.
How to use?
It is recommended to wear glasses for vision training for thirty minutes during the day. They are allowed to work at the computer, read books, and watch television programs. The main thing is to take care of good lighting.
When watching TV or working on a PC, try not to focus your gaze on one point, avoid “freezing”, this leads to additional strain on the organ of vision. Make your eyes work, look at various objects on the screen. Periodically move your gaze from the monitor to objects located nearby or far away.
Schoolchildren and students, as well as those whose activities are related to computers, should use the simulator for five or seven minutes for every hour of visual work. You can restore eye sharpness with myopia or hypermetropia only if you exercise regularly.
How to use glasses
Training glasses can be used as a complement to methods of vision restoration based on regular eye exercises, such as the Bates method.
They are also suitable for use as an alternative to these methods - in this case there is no need to perform exercises, you just need to put on perforation glasses from time to time and wear them for a while. While wearing glasses, you can do any household chores, read or watch TV, or work at the computer.
If you combine wearing glasses with exercise, the effect of relaxing your eyes and improving your vision will be most noticeable.
Combine training glasses with exercises to restore vision
Manufacturers of training glasses recommend starting with plates with cylindrical holes and wearing them until you get used to it, which usually takes 1-2 months. Then you need to switch to glasses with cone-shaped holes, also wear them until you get used to it, and then switch again to glasses with cylindrical holes.
Basic recommendations for use:
- It is necessary to wear perforation glasses in good lighting;
- They should be used no more than 3 hours a day.
Also, when wearing perforation glasses, some caution must be exercised. For example, it is better to refrain from working with sharp objects; you should not use them on the street, and you should not drive a car in them.
To achieve a good effect, wear glasses regularly
To achieve good results, it is very important to wear these glasses regularly. At the same time, it is important not to overdo it - wearing them too often will not increase the effect; on the contrary, there is a risk of developing eye problems. For example, if you wear pinhole glasses for too long, binocular vision deteriorates.
In addition, you need to consider that training glasses also reduce the amount of light that reaches the eyes. Therefore, you should not wear them in poor lighting conditions.
Eye exercises with perforation glasses
Once you start therapy using exercise machines, you need to practice on an ongoing basis. Otherwise you won't see any results. Some exercises will help increase the effectiveness of your classes:
- Close your eyelids for ten seconds and relax. This technique must be repeated after each exercise described below;
- Place a small picture (1*1 centimeter in size) on the window, stand at a distance of thirty centimeters from it. Gaze into the distance for three seconds, then return your gaze to the image for five seconds. Do six to eight times;
- Squeeze your eyes tightly and open your eyes wide. Do ten approaches;
- Rotate your vision in one direction, then in the opposite direction. Repeat six times;
- Follow the tip of your finger, slowly bringing it closer to your nose at a distance of five centimeters, then remove it. Perform eight repetitions;
- Extend your arm and focus your gaze on the tip of your finger, which is located vertically in front of your organ of vision. Slowly move your finger closer, without taking your eyes off it, until the picture begins to bifurcate. Repeat six times;
- For eight seconds, look at the tip of your finger, which is located at arm's length from your face. Close your left eye with your left palm for five seconds, then peer at the picture with both eyes for the same time interval. Repeat the manipulations for the right eye. Do five times for each side;
- The head remains in a static position, slowly move your palm in front of the organ of vision, first from left to right, then in the opposite direction. Repeat ten times;
- Remove the polarizing eyepieces and blink intensely for sixty seconds. Then close your eyelids and lightly massage your eyes for a minute.

Do glasses improve vision?
The product is widely available and can be purchased not only in specialized optical stores, but also on the Internet. But are they any use? Are they suitable for everyone? People were divided into two camps: practitioners and theorists. Some, without providing any facts, advise wearing exercise equipment everywhere and always. Others claim that there is no benefit from them and do not recommend relying on advertising.
So which one is right? There is probably some truth in everyone’s words. It is a misconception to think that glasses with holes, as if by magic, will cure you of all ophthalmic problems. This is wrong. The perforation simulator is a medical device; accordingly, it has a number of recommendations for wearing and contraindications for use.
| Therefore, before purchasing optics, you should consult a doctor. He will tell you whether training with “holey” glasses will have an effect or whether you should refrain from such training. |
