Top 5 hazards of winter


Frost and sun;a wonderful day!Once you doze, one adorable?It is time, beauty, wake up: open the eyes are closed bliss ...

What imagination draws a picture of where you are reading these popular lines of poetry?The white snowdrifts, sparkling in the bright sun?The snow crackling under your feet in the frost?Deep blue sky?A full long sleep and a pleasant awakening in a good mood?Alas, some come to mind rather pessimistic picture: snow blindness, conjunctivitis, cold, watery eyes, short light day, and he spent at the computer, and as a consequence - visual fatigue, chronic sleep deprivation, painful climb up the alarm clock and more serried inflamed "eyes. "We will understand how to defeat the main enemies of eye health and to generate extremely positive attitude to poetry, not darkened as unpleasant associations.

1. The treacherous snow
winter, eyes suffer from the effects of ultraviolet light is not less than in summer.The brightness of the rays of the winter sun, reflected on the white sparkling
snow, sometimes even more intense than a summer day at the beach.The reaction of the eye does not have to wait long: there is photophobia, blurred vision deteriorates.There's even a disease - "snow blindness" in which the ultraviolet rays reflected from the surface of the snow, causing the eyes not only uncomfortable, but can cause a burn and, as a result of a person to temporarily lose vision.This disease often occurs in climbers and those who spend time in the mountains.

What to do: If there is no congenital abnormality associated with pigmentation disorders of internal structures of the eye, it usually can be solved with the help of sunglasses.There are different categories of lenses with UV filters.Lenses with first and second degree of light transmission designed for simple urban environment, with the third - for the bright winter lenses with fourth - the darkest, designed to protect the eyes in the mountains, and will be useful for those planning to spend a winter holiday PA ski resorts.The factor of protection from UV rays and has a range of contact lenses correctly to pick you will only ophthalmologist.

2. Frost provocateur
Quite often happens is that when we go out into the cold winter, the eye begins to tear.The fact that at low temperature tear ducts spazmiruyutsya, concerning the tears tear during normal operation of the system should go into the sinuses, there are not available, but remain in the eye, thereby tearing arises.This reaction can also be caused by high sensitivity of the cornea to weather or light conditions, "cold" or "solar" allergies.

What to do: It is necessary to go to the ophthalmologist, that he discovered the cause watery eyes and assigned appropriate treatment, taking into account the individual characteristics of the reaction of your eyes.For example, in the case of allergies to ultraviolet radiation will be advised to follow a diet, use special tools - korneoprotektory and taking antihistamines.If the retina is exposed to disease, the doctor will recommend a course of treatment medicines containing pigments, which effectively protects it from ultraviolet radiation and other adverse effects.If a strong stream of tears caused by the disruption of the tear duct, a person needs a procedure that helps to normalize the nasopharynx.In a number of cases, appointed by washing tear ducts using special probes introduced through the nose.This procedure is not very pleasant, so in some hospitals, especially children, it is preferably carried out under light anesthesia the mask.

3. Dry air
winter, as a rule, because of the hot radiators, heaters included, insufficient ventilation and windows closed indoor air is too dry.In such circumstances, the tear film evaporates quickly - eyes redden, tears uncomfortable.Particularly vulnerable to the "dry eye syndrome" those who have to spend a lot of time in the classroom or on the computer.

What to do: If possible, ventilate the room and resort to the help of special devices - humidifiers.Every day there is dry cleaning.Drink plenty of fluids.Independently appoint a so-called slezozameniteli no hurry - they are shown and not all are useful.In no case does not drip such drugs to children.Sometimes the "dry eye syndrome" may be the first call, warning of serious problems with eyesight.If the mask pattern of the disease with the help of slezozameniteley, this will complicate diagnosis and treatment.Only an ophthalmologist after inspection and survey able to properly assess the situation and make the necessary tests for the production of tears and tear film stability and appropriate treatment.

4. Road distant
your spouse spends a lot of time behind the wheel, and you sometimes take the car my husband to pick up children from school or get comfortably to the supermarket?Then you know how difficult it is to drive in the winter.This time of year is not pleased with a clear picture: twilight lighting conditions, weak image contrast or, conversely, bright sun glare on snow-covered roads, hinder all good to see while driving.

What to do: Pick up the spectacle lens-specific filters.Thus, for example, yellow or orange filter increases winter contrast in low light conditions.Brown filter is required when increased solar activity, including when traveling on the snowy slopes.The most versatile is considered gray light filter, it is suitable for different conditions.In the fight against blinding glare out of competition - polarized lenses.If in the evening you have the visual acuity is reduced, there is a feeling of sand in the eyes, they are tired too quickly, often inflamed, you should not put off a visit to the ophthalmologist.The doctor will determine the cause of this condition and with a decrease in visual acuity you select the right glasses.

5. Few light
no secret that many of the protective functions of the body are directly dependent on how much or little it receives natural light.Thus, in winter, when solar activity is not great, reduced immune function, there is a tendency to increased fatigue and apathy of which is further enhanced due to the artificial lighting.Remember that fluorescent lights for home use are not suitable, they are only good for backlighting.Such lamps really strain your eyes, and on the functioning of the cardiovascular system have a negative impact.Experts in the field of health warned that energy-saving lamps provide lighting bright white color, which increases the load on the vision and strengthens the eye muscles fatigue.

What to do: In the winter it is not necessary to hang dark curtains on windows to maximize natural light.In the afternoon, if the weather is clear and sunny, include electric lamps is not necessary.Due to lack of light eyes are not tired and do not overexert, take care of the well-lit work space.Change the lamp careful not after they burn out, but when the light from them begins to wane significantly.Colors lampshades desirable to choose cool colors, the best blue or gray.They do not cause excessive eyestrain.

useful ration of
help improve vision menu, which contains foods rich in vitamins A, E, C, B group, as well as omega-3 and trace element zinc.This fish, meat, poultry, peas, spinach, legumes, nuts.Make eye less vulnerable capable nutrients lutein and zeaxanthin, substances related to beta-carotene, and the ability to accumulate in the retina.Their main sources - spinach, lettuce, egg yolk, red bell peppers.
