It is believed that perforation glasses, they are in everyday life - glasses with holes, can solve some vision problems, in particular to cure myopia. We decided to check if such an opinion is reasonably.

Glasses With holes advertised on the set resourcesdedicated vision. Their Consult Apply for myopia (myopia), astigmatism, farsightedness, presbyopia, retinal degeneration and even cataracts. Some Russian manufacturers indicatethat their goods are approved by the Ministry of Health of the Russian Federation. Media also recommend that the media recommend: for example, in 2002 in the newspaper "Trud" I went out An article entitled "Bowing your eyesight?". Its author reported that “Famous scientists gave reviews on the glasses-tranels, and 12 research and leading ophthalmological clinics” recommended the production [model] “Super-Vizhn”. IN Internet Can Meet many reviews, authors which They say that Returned Enstrages thanks to such glasses.

Usually perforating glasses are a plastic or metal frame, into which plastic plates with many round holes located in a certain order are inserted instead of classic lenses. Such glasses work on the principle Cameras -obskure - the look through the narrow hole allows you to reduce the scattering stain on the retina of the eye, thereby increasing the clarity and sharpness of the image. Also, their principle of operation can be compared with how we are squinting in order to better see anything. Manufacturers Such glasses Explain: Vision should improve because without eyes the eyes are “lazy” and does not load the ciliary muscle - it is responsible for accommodation, that is, the adaptation of the eye to various conditions. It is the training of the ciliary muscle who supposedly should help defeat myopia and other visual impairment.

However, the latest scientific research Showthat the main reason for myopia is genetic. So, if one of the parents is diagnosed with myopia, then with a probability of 25% it It will appear And at the child. If the short -sighted ones are both parents, the risk of developing pathology in a child increases to 50%. It is logical that it will not be possible to change the genetic predisposition only by training of the muscles of the eye. Experts of the authoritative Cleveland Clinic (USA) List Methods of correction of myopia: glasses, lenses, including orthoperatological or night, laser operations, implantation of fakid intraocular lenses and gymnastics for the eyes, if myopia is caused by spasms. There are no perforation glasses among the funds that proved their effectiveness. No national service UK health care, nor American association optometrists, nor the Federal Scientific and Clinical Center of the Federal Medical and Biological Agency (FNCC FMBA Russia).

Similar story and with astigmatism -distorting the refraction of light in the eye due to the stretching of the cornea or lens into the irregular oblong shape. Muscle training, due to the presence of holes in special glasses, is impossible to cure this pathology. To date, doctors Offer Such patients adjust vision with ordinary glasses and contact lenses or change the curvature of the cornea surgically.

Perforation glasses do not help and with Presbiopia - the age -related abnormality of the eye refraction in which there is a violation of accommodation. Scientists agree that Presbiopia is a natural process of aging along with the advent of gray hair and wrinkles, in the same way the lens loses its elasticity over time. Time to turn and make the eyes younger than glasses with holes, of course, cannot. Presbiopia is mainly treated with surgically - laser correction or replacement of the lens. Also in 2021 in the USA Out On the market, the first eye drops that can fight this pathology. The main active substance of the drug is the cholinergic agonist of the muscarine row, activating muscarin receptors located on smooth muscles, such as the circular muscle of the rainbow shell (sphincter of the pupil) and the ciliary muscle.

At cataract - Clouding crystal Due to protein denaturation - glasses advertised on the Internet will also not help, since they do not affect the cause of the violation. Cataract is treated only with a surgical way with implantation of an intraocular lens.

Thus, with any of the stated visual impairment, perforation glasses do not help simply because they do not affect the cause of the violation. And although such points are sold in many countries, in 1993 the US Federal Trade Commission Forbidden Advertising of perforation glasses as a way to improve vision, since they did not give the declared effect. The experts of the commission concluded that the use of the device does not lead to a long -term vision improvement, does not heal and does not correct specific vision problems, cannot be adequate to replace the recipe contact lenses and glasses, and the gymnastics program does not strengthens the muscles of the eye and does not improve vision.

But can such glasses be useful in that they protect against the appearance of problems with vision in the future? The answer to this question was tried to find Korean scientists. In 2014 they Spent quantitative analysis of functional changes caused by wearing perforation glasses. Researchers did not receive a definite positive result. When wearing glasses with holes, participants improved visual acuity, depth of sharpness of the image and accommodative amplitude, but the quality of vision, contrast sensitivity and stereopsis - a subjective sensation of the depth of space, and the field of vision, have decreased. Scientists did not record any long -term effects.

In 2017 the same team investigatedHow useful it is to read in perforating glasses. For this, scientists invited 36 volunteers who were offered to take a series of medical measurements of visual acuity and read the text of the Korean fairy tale at first without any glasses, then in perforating glasses and, finally, in glasses with one narrow hole on each of the two plates (such a device, according to manufacturers, also improves vision). After each stage of the experiment, the participants evaluated their condition according to the seven parameters: eye fatigue, a feeling of tension, a burning sensation, discomfort in the eyes, difficulties with focus, complexity of concentration, blurred vision and double eyes. It turned out that both types of glasses improved the accommodation of the eyes in the short term, but along with this significantly reduced reading speed and caused symptoms of strong discomfort for the eyes.

Review of 2021 Supplies Bottom line: glasses with holes cannot improve vision in those who suffer from myopia, presbyopia and astigmatism, and will also not serve for the prevention of such diseases. For a short time, when a person with vision pathology wears such glasses, they can provide a more clear image, but the same effect will give simple squinting the eyes. However, it is not worth calling the perforation glasses useless-they are appropriate in the office of the ocular doctor, as they help a specialist diagnose various diseases.

Thus, manufacturers' statements about miraculous glasses with holes do not correspond to scientific data. Perforation glasses will not relieve many common vision problems, since they do not affect the cause of the disease. Long -term changes in the eye from wearing such glasses are also not expected. When reading, glasses with holes improve some indicators of vision and worsen others, so it is also impossible to consider them a full prevention of visual fatigue. Instead of perforating glasses to relieve tension from the eyes, doctors Recommend adhere to the “Rules 20–20–20” - every 20 minutes of work it is necessary to take a break and take a look at an object located at a distance of 20 feet (about 6 m) for 20 seconds.
