The factors that put your eyes at risk in winter
Main risk factors for winter eyes: viral conjunctivitis, adverse weather conditions and ultraviolet radiation.
Eye dryness, irritations or ulcers are some of the most common discomforts of the colder months.
The eyes are very sensitive to the meteorological changes that occur when we move from one station to another.
Especially in those seasons with more extreme temperatures, such as summer and winter.
During the coldest months of the year three risk factors for the health of our eyes:
Increase in viral conjunctivitis.
At this time of year higher rates are registered of what is known as viral conjunctivitis.
A type of conjunctivitis caused by the same viruses that cause flu in winter.
The most typical symptoms are redness of the eye and secretion of it and it usually lasts around 10 days.
As with the influenza processes, it is difficult to give some previous advice to avoid contracting viral conjunctivitis.
At the first symptoms, the best is go to the ophthalmologist who will schedule a treatment to combat the viral process while mitigating the discomfort.
In addition, from Clínica Baviera recommend that the person increase the hygienic measures on those days to avoid contagion.
Do not share towels or pillows, wash hands after touching the eye or ventilate the rooms.
Adverse weather conditions.
On the other hand, the climatic conditions of the winter can cause a greater environmental dryness and a poor lubrication in the eye.
It manifests itself in symptoms like blurred vision, itching and burning.
These symptoms increase even more with the presence of wind and pollution in the open places and the use of heating in the closed.
So, suffering dry eye is very common in these dates.
To mitigate it, the best is protect the eyes with glasses, hydrate them using artificial tears and, in closed environments use humidifiers.
If it has been exposed to cold, wind or contamination, it must be rest your eyes for some minutes and not punish it with the abuse in the use of electronic devices, etc.
Exposure to ultraviolet radiation.
Another risk factor is exposure to ultraviolet radiation, higher in these months, since the sun is lower and at a different angle.
Also in winter, unlike in summer, we are not usually aware of the importance of the use of sunglasses.
The precautions with ultraviolet radiation they must be greater in the case of those who practice sports in the mountains.
At high altitudes the protection capacity of the atmosphere is much lower than in the lower areas.
It is estimated that for each 1,000 meters of height, the damaging effect of solar radiation on the eyes increases by 15%.
In addition, snow reflects 80% of the ultraviolet rays, so ocular overexposure to this light can produce a keratoconjunctivitis solar(inflammation of the conjunctiva and the cornea, also called ophthalmia of the snow).
Habitually, symptoms of ophthalmia of the snow appear between four and six hours after exposure to ultraviolet radiation.
Therefore, almost always affected people are already in their homes when they begin to feel discomfort.
For example, tearing and photophobia, red eyes, headache, blurred vision and / or decreased visual acuity.
In case of suffering these symptoms it is recommended go to an ophthalmologist as soon as possible who will study the case and give appropriate treatment guidelines to prevent a major condition from occurring.
The preventative measure par excellence to avoid this type of injuries is protect yourself from ultraviolet radiation by using dark glasses with an adequate UV filter (filter 4 is recommended for practicing these sports).
Cover the eye completely and also protect from the wind.
