It is believed that constantly wearing glasses relaxes the eye muscles, which makes it more difficult for the eyes to focus on objects without correction means. This is wrong, but only partly - there are some factors that influence vision deterioration when wearing glasses for a long time.
Not everyone can wear glasses all day without taking them off. Everyone has their own reasons for this. There is a misconception about constant wearing as a factor that contributes to visual impairment. With constant use of glasses correction, it can worsen only through the fault of the person himself and only in three cases:
- Incorrect selection of optics.
- Inconsistency between the mode of use and the degree of eye disease.
- Rare visits to the ophthalmologist's office and non-compliance with his recommendations.
Incorrectly selected spectacle correction products
Many people often purchase them without a doctor's prescription. However, incorrectly selected or low-quality lenses pose a threat to eye health, as they will be under constant strain. Because of this, the distance between the pupils may change.
When purchasing, it is important to pay attention not only to the lenses, but also to the frames, temples, and nose pads. If you are careless about their choice, this will lead to discomfort and pain.
Only an ophthalmologist will determine all the necessary indicators based on individual characteristics. Then using glasses will be comfortable and safe.
Can wearing sunglasses damage your eyesight?
Today, sunglasses are an accessory that not only performs a protective function for the eyes when the bright sun is shining, but is also an indispensable attribute for creating a bright, stylish look. There is an opinion that some glasses can seriously damage your vision. Is it so?
Of course, the main task of glasses with dark lenses is to protect your eyes from the harmful effects of UV radiation. Having this accessory is very important, because if you do not wear sunglasses, pathologies such as cataracts (clouding of the lens), conjunctivitis, dry eye syndrome and even retinal burns can develop.
However, not all models of glasses are able to adequately protect the visual organs from exposure to ultraviolet radiation. For example, accessories with low-quality lenses can cause serious harm to the health of the visual system.
Non-certified glasses most often do not have a special coating with a UV filter on the lenses; they are simply painted in a certain shade and only create the appearance of protection. In fact, such lenses allow ultraviolet rays to pass through.
Ophthalmologists warn that using cheap fakes is even more dangerous than not wearing sunglasses at all. The fact is that when a person’s eyes are behind a dark surface, they are completely open and receive more UV radiation than when they are without glasses, because we squint or cover our faces with our hands.
In addition, low-quality lenses can distort the image, which negatively affects the quality of vision. The eyes are forced to strain, this leads to rapid fatigue, and subsequently to a decrease in accommodative ability.
To make sure that your sunglasses are of really good quality and can protect your eyes from the sun, pay attention to the temples. There must be the letters CE, this means that the product is certified. You can also distinguish an original model from a fake by the presence of documents or labels indicating the degree of protection. It is better to pay attention to glass lenses, since it is plastic optical products that can affect the quality of vision.
It is better to buy glasses in specialized online optical stores or salons. Before choosing a model, you can consult with a specialist who will tell you which lenses with what degree of protection will suit you.
Experts recommend paying special attention to protecting the visual organs from an early age, and also avoiding exposure to bright sun between 9 a.m. and 4 p.m. If you have poor vision, use contact lenses with a UV filter for added protection.

Many people have sunglasses. Today they are no longer treated as a purely summer accessory, so you can increasingly see people wearing sunglasses at any time of the year when the sun is shining brightly.
However, some are still afraid to wear them because they believe that they can harm their eyes and ruin their vision. Experts explain why this statement is fundamentally wrong.
Why do you need sunglasses?
Already from the name it follows that they are designed to save the eyes from the sun, namely from harmful ultraviolet radiation. If you don't wear dark glasses, you risk developing diseases such as cataracts, conjunctivitis, retinal burns and dry eye syndrome.
Do all glasses offer the same protection from the sun?
No. Only original certified products have protective properties, while counterfeits and low-quality glasses can cause real harm to eye health.
What are the harms of low-quality sunglasses?
The lenses of these glasses do not have a special coating, they are simply painted a certain color. Therefore, they only create the appearance of protection, but in fact they allow harmful ultraviolet rays to pass through.
Wearing fake glasses is even more dangerous than not wearing glasses at all. And that's why. With glasses, our eyes are completely open because they are covered by a dark surface. And if they are of poor quality, then the eyes receive an even greater dose of UV radiation than would be the case without glasses. After all, when they are not there, we squint or cover our eyes with our hands.
If you do not use sunglasses or wear low-quality products, then you risk encountering cataracts, since there is a close connection between its occurrence and ultraviolet radiation.
How to protect your eyes from the sun?
You should not expect that cheap, albeit beautiful, glasses with dark lenses, bought at the market or in a clothing store, will protect your eyes from the sun. Buy only high-quality certified glasses.
How can you be sure that your sunglasses are actually sunglasses?
Firstly, quality products have certificates of conformity - the letters CE on the arms. In addition, original glasses can be distinguished from fakes by the presence of supporting documents and labels indicating the degree of protection.
Secondly, pay attention to the reliability of the seller and buy glasses only at specialized points of sale and optical shops.

Poor vision: how to solve the problem and get rid of glasses and contacts in one day
Nearsightedness, farsightedness and astigmatism can be corrected using a laser, but not all technologies are created equal.

According to statistics from the Ministry of Health, every seventh Russian suffers from eye diseases, and constant work on the computer and telephone provokes deterioration of vision. Poor vision is an unaffordable luxury for a successful, wealthy and educated person leading an active lifestyle. Visual acuity is important both in meetings and when driving, and water and contact sports may not be compatible with glasses and contacts.
Vision problems are not always solved by traditional glasses (high degrees of myopia and astigmatism, differences in diopters between the eyes), and contact lenses can have a negative effect on the cornea of the eye, especially when worn for more than 8 hours. Improper use or careless handling often leads to the development of an inflammatory process - keratitis, which in severe cases may require a corneal transplant. Even modern contact lenses do not guarantee all-day comfort, causing dryness and redness of the eyes when working at a computer or staying in an air-conditioned room for a long time.
A comfortable solution for excellent vision is modern laser correction. Today, lasers can instantly correct nearsightedness, farsightedness and astigmatism. However, not all technologies are created equal.
Evolution of methods
One of the first methods of laser vision correction was photorefractive keratectomy (PRK). The procedure involves mechanically burning out the superficial and deep layers of the cornea and then covering it with a special lens. Unlike more innovative approaches, PRK requires long-term rehabilitation, is not used for high degrees of myopia, and the patient experiences severe pain after surgery.
Another vision correction technology that combines microsurgical intervention and excimer laser technology is called LASIK. During the operation, a “lid” is formed in the cornea using a special blade. A thin flap is formed on its surface; during the operation it is folded back, part of the cornea is evaporated, and the “lid” is closed again.
The main disadvantage of LASIK is that after the procedure the patient is left with large incisions, and the formed “cap” never grows back, which leads to a significant decrease in the strength of the cornea and increases the risk of displacement of the “cap”. In this regard, patients after LASIK are not recommended to engage in active sports, since if there is an impact, the “lid” may move and the problem will require immediate attention to a surgeon.
With femto-LASIK, a femtosecond laser comes to the aid of the surgeon, which makes the cut more precise, but does not eliminate the technology from a flap on the cornea.

Today, outdated methods have been replaced by the third generation technology ReLEx SMILE (SMILE) - 100 percent femtosecond laser vision correction by removing lenticules through a small incision of the cornea (SMall Incision Lenticula Extraction). The method allows you to improve your vision as quickly as possible - the laser operates for 25 seconds. During corneal correction, a 3-D modeling of the lens is performed, which is subsequently removed by the surgeon through a two-millimeter incision. This requires a unique VisuMax laser and high skill of the surgeon.
Expert commentary
“SMILE can be used even when other laser correction methods are not possible - it expands the boundaries for vision restoration for myopia and astigmatism. The method allows you to safely operate even on a thin cornea, preserving its strong outer part. In the first hours after correction using ReLEx SMILE technology, a person sees as if through foggy glass, but vision is already good and improves every hour. We had patients who, within an hour after the correction, saw well and drove away behind the wheel of a car, although we, of course, do not recommend driving on the day of the operation,” says an expert on the SMILE procedure, professor, doctor of medical sciences, head of the Russian department European network of laser vision correction clinics SMILE EYES Tatyana Shilova.

The latest generation ReLEx SMILE technology does not imply a long rehabilitation period and completely eliminates the risk of the “lid” being displaced. In many ways, a good result depends not only on the equipment, but also on the doctors and clinics where SMILE correction is performed.
“We have people from show business undergoing surgery who set aside an evening for the procedure, and the very next day they come to work made up and dressed up. Athletes also choose our clinic. They cannot take a break from training, so the ReLEx SMILE method is the most optimal for them. In addition, many patients come from the former CIS countries, Europe, the USA, and China. They are attracted by the quality of medicine, world-famous surgeons and the cost of surgery.
It is important that we carry out preoperative diagnostics according to 100% European standards, and when carrying out correction we use nomograms (corrections) from the entire network of SMILE EYES clinics to obtain the best results. Visual acuity after surgery is often 120% and 150% of normal. We fully manage the patient and observe him for a year after the operation free of charge,” added Tatyana Shilova, head of the Moscow SMILE EYES clinic.
Of course, modern technologies are somewhat more expensive than their predecessors, but their use can be considered as an investment in your health. By paying once, a person gets excellent vision for many years, so it is worth choosing the best specialists and modern correction methods.
There are contraindications. Specialist consultation is required.
