Computer vision syndrome

Computer vision syndrome is a group of symptoms that occur as a result of long-term work in front of a computer. Initially, it is manifested by eye fatigue, heaviness of the eyelids, frequent blinking. Sometimes a feeling of sand or blurred vision may occur. If no measures are taken in time, the condition may worsen. Hypersensitivity to light, lacrimation and other phenomena that disrupt the normal functioning of the visual organ may develop. In some cases, computer vision syndrome is manifested by pain in the head, discomfort in the neck, shoulders, back, and unpleasant sensations during eye movements.

Visual disturbances that may occur during computer vision syndrome, as a rule, do not lead to serious eye diseases, but significantly worsen the quality of life. In order to avoid this, it is necessary to regulate the load on the eyes in front of the computer, as well as choose appropriate glasses and contact lenses.

Causes of computer vision syndrome

The development of the syndrome is not associated with monitor radiation. The essence of the problem lies in the perception of the image from the screen by the eye. For example, in a book, the image does not glow on its own, does not flicker, so reading does not require much effort on the eyes. But when working with a computer, the image is illuminated and consists of a set of many small dots, pixels, which are constantly flickering. Even if this flickering is not visually noticeable, the eyes still get more tired from looking at the screen than from reading a book or magazine.

Computer vision syndrome can often develop in the following cases:

•Incorrect organization of the office: a greater or lesser distance from the monitor than the norm, high screen brightness, the need to constantly change your gaze from the monitor to the papers and vice versa, etc.

•Long and continuous work in front of the computer - when we look at the monitor, we unconsciously blink less and, consequently, the eyes become less moistened, which in turn leads to a violation of the quality of the tear film. Thus, the protective and lubricating functions of tears suffer, which contributes to the development of dry eye syndrome, which is accompanied by tearing, tearing, and discomfort in almost 50% of office workers.

•The presence of monitor glare - any light source, falling on the screen, increases eye strain.

How to deal with monitor glare

To get rid of glare and thus reduce strain, first of all, you should place the computer monitor so that the windows are located to the side. If this is not possible, then you should close the curtains so that excess light does not fall on the screen. Bright ceiling lights should be turned off or replaced with lamps of lower intensity. The desk light should be positioned so that it does not shine directly on the screen and into the eyes.

In addition, the use of computer glasses with special anti-glare coating gives good results.

The brightness of the computer screen should be adjusted - it should not be too bright, but not dim.

The eye perceives information more easily if high contrast is set in the monitor settings. The color of the screen is also important - it is desirable to work on a black and white or light yellowish background.

The brightness of the general lighting in the room should match the brightness of the monitor. All this reduces the likelihood of developing computer vision syndrome.

It is recommended to take short breaks from work, every 10-15 minutes. During this time, you can focus your eyes on objects outside the window or in the distance if there is no window nearby. The eyes should be given a rest at least once an hour. It is advisable to perform exercises that relieve eye fatigue.

Why is it important to sit correctly

The visual image is formed in the occipital lobe of the brain. The full blood supply of these sections depends on the health of the vessels of the cervical region. Incorrect position of the body, head and neck contribute to muscle spasm and tension, which in turn leads to compression of the carotid and vertebral arteries and a decrease in oxygen supply. This condition leads to weakness and dizziness, fatigue. Physiotherapy measures reduce the risk of developing complications and prevent the occurrence of computer vision syndrome.

Prevention is always preferable to treatment, so you should properly organize the workspace and computer monitor so that the eyes do not suffer. It is recommended to use moisturizing drops, eat foods rich in vitamins.

Any eye diseases, including computer vision syndrome, require consultation with a highly qualified specialist who will select the safest and most effective treatment tactics.

Gastritis

Gastritis is an inflammation of the gastric mucosa. We distinguish between acute and chronic. Acute gastritis can be caused by the development of an inflammatory process in the gastric mucosa, which can have varying degrees of severity, from superficial to deep necrotic changes.Symptoms of gastritis: •Abdominal pain •Nausea •Vomiting •Loss of appetite •Heartburn Complications of gastritis include: •Bleeding •Stomach ulcers •UlcersCauses of gastritis: •Helicobacter pylori •Stress •Use of nonsteroidal anti-inflammatory drugs •Poor diet •Alcohol •Smoking •Crohn's disease •Diagnosis Sometimes the diagnosis can be made based on the patient's description of the symptoms. •Helicobacter pylori presence •Endoscopy •Gastric biopsy •X-ray examination •Stool sample Chronic gastritis Chronic gastritis develops due to prolonged exposure to adverse factors on the gastric mucosa: irregular eating habits, systematic overeating with proteins, consumption of dry or poor-quality food, hard or spicy foods, eating too hot or cold food, prolonged use of certain medications. Chronic gastritis can last for a long time even without symptoms. If left untreated, gastritis can lead to stomach ulcers and bleeding. Rarely, some forms of chronic gastritis can increase the risk of stomach ulcers, especially if they have severe thinning of the gastric mucosa and changes in the cells of the mucous membrane <<mutations>>. Medications used to treat gastritis include the following: •Antibiotics that kill Helicobacter pylori •Acid-suppressing and healing drugs •Stomach acid-neutralizing drugs (antacids) Acute gastritis caused by nonsteroidal anti-inflammatory drugs or alcohol may be relieved by stopping their use.If you notice any symptoms of gastritis, consult a doctor promptly to prevent serious complications.

Anti-aging

28 April 2025

Originally, the term "anti-aging" originated in cosmetology and was understood as an exclusively cosmetic approach aimed at improving appearance. However, today, in the era of increasing life expectancy and “maturing” of the human population, it is time to interpret the concept of “anti-aging” more broadly and “get out” of new technologies of face masks, creams and “beauty injections”. In a global sense, anti-aging is neither “external cosmetic repair” nor “rejuvenation” (which is absolutely impossible), but strategic planning of all spheres of life: nutrition, physical and mental activity, reproductive behavior, work mode and breathing, sleep and exercise, which should begin with the preventive stage. To ensure longevity, a change in lifestyle is necessary, which really allows to delay old age and prevent age-related diseases: •maintaining normal body weight •maintaining physical activity •a balanced diet and drinking regimen •optimization of the work and rest regime, 8-hour sleep •preservation of cognitive functions: mental activity, solving crossword puzzles, learning foreign languages, reading •determining development prospects, hobbies, "life's work" •getting rid of bad habits •regular research

Bacterial Vaginosis

27 April 2025

Bacterial vaginosis is a common vaginal infection, affecting around 23–25% of women of reproductive age. It develops when the natural balance of vaginal bacteria is disrupted. Normally, the vagina is protected by Döderlein's cilia (lactobacilli), which maintain an acidic environment. When these beneficial bacteria decrease, harmful microorganisms like Gardnerella spp., Prevotella spp., and other anaerobic bacteria can multiply, leading to bacterial vaginosis. Women with bacterial vaginosis may notice unusual vaginal discharge, a fishy odor, itching, or irritation, although some may not experience symptoms at all. Causes of Bacterial Vaginosis Bacterial vaginosis can be caused by several factors, including: 1.Violation of hygiene rules – Overwashing, use of harsh soaps, or vaginal douching can upset the natural balance. 2.Chronic intestinal diseases – Conditions like Irritable bowel syndrome or frequent digestive issues may impact the vaginal microbiome. 3.Previous inflammatory diseases – Past infections of the urinary or reproductive system may leave the area more vulnerable. 4.Decreased immunity – A weakened immune system can reduce the body’s ability to fight off harmful bacteria. 5.Atrophy of the vaginal mucosa – Common in menopausal women, this can reduce natural defenses. 6.Hormonal disorders – Hormonal imbalances may alter vaginal pH and increase susceptibility to bacterial vaginosis. Treatment of Bacterial Vaginosis Bacterial vaginosis is treatable and curable. Treating a sexual partner is decided on a case-by-case basis. While bacterial vaginosis is not a traditional sexually transmitted infection, sexual activity can influence vaginal flora, especially in recurring cases. To prevent bacterial vaginosis, it's important to avoid practices that disturb the vaginal environment. Regular visits to a gynecologist are essential for early detection and effective management of vaginal health.

Pneumonia

27 April 2025

Pneumonia is a group of acute infectious (mainly bacterial) diseases of the lungs with different etiology, pathogenesis, morphological picture and clinical manifestations, which are characterized by damage to the respiratory sections of the lungs and the formation of an obligatory inflammatory exudate in the alveoli. This definition of pneumonia emphasizes the infectious origin of the exudative, inflammatory disease of the alveoli, which develops in response to the introduction and proliferation of microorganisms in the pulmonary parenchyma. In contrast to the latter, inflammatory diseases of the alveoli of non-infectious origin are called pneumonitis. Pneumonia classifications 1.Community-acquired pneumonia 2.Hospital-acquired pneumonia 3.Aspiration pneumonia 4.Pneumonia in patients with immunodeficiency states. Symptoms of community-acquired pneumonia are: 1.Fever 2.Cough with or without sputum production 3.Chest pain of a pleuritic nature 4.Shortness of breath 5.General intoxication syndrome. Acute onset of the disease with a rise in temperature to 38* and above, sudden occurrence or significant intensification of cough with the release of purulent or hemorrhagic sputum, the appearance of percussion and auscultatory phenomena, leukocytosis or leukopenia, X-ray signs of pneumonia. Treatment The duration of treatment for community-acquired pneumonia is on average 7-10 days. The minimum duration of treatment is 5 days if the patient has not had a fever for 48 hours and has no more than one clinical symptom associated with pneumonia.Hospital-acquired pneumonia Hospital-acquired pneumonia is most often caused by highly virulent autogenous microflora or pathogenic strains circulating in the hospital: pneumococcus, staphylococcus aureus, klebsiella, enterococcus, proteus, bluetongue, legionella, anaerobic bacteria. Pathway of invasion of microorganisms 1.Innate path 2.Airborne 3.Hematogenous 4.Contagious Hematogenous and contagious paths occur rarely. Pneumonia can progress quickly and cause serious complications. Early medical consultation ensures proper diagnosis and treatment, reducing risks and promoting a faster recovery.
