The tear film, tears are essential for good vision, for the lubrication of the eyes and to remove foreign bodies or small particles.
Dry eye develops when the eye loses the ability to maintain healthy tear film.
Dry eye usually occurs in healthy people and becomes more common as you age, as a result of hormonal changes that lead to the eyes produce fewer tears.
Other causes include:
Drugs for colds or allergies
Dry environment (eg air conditioning or wind)
Smoking and passive smoking
Previous eye surgery
Heat or chemical burns
Sjogren’s syndrome (rare autoimmune disorder in which the glands are destroyed that produce tears)
Burning, itching, or redness of the eye
Gritty feeling in the eyes
A first step in treatment is the application of artificial tears which there are several brands available in the market without a prescription.
The recommendation is to use the drops at least 2-4 times a day, if your symptoms do not improve use regularly for a few weeks taking into account the following considerations:
Try a different brand
Consult a doctor if you get a brand that works
Increase use every 2 hours
Other medical treatments may include:
Safety glasses or contact lenses to retain moisture in the eyes
Tiny plugs placed in lacrimal drainage ducts moisture to remain on the surface of the eye longer
Fish oil 2 to 3 times per day
Drugs such as topical corticosteroids, oral doxycycline and tetracycline
Some measures that can be useful:
A humidifier, particularly in the winter
Rest your eyes regularly
Purposefully blink regularly
Do not smoke and avoid smoky environments, air conditioning or direct wind
Reduce consumption of cold medicine or allergy that may worsen the symptoms
Clean regularly lashes and apply warm compresses
In some cases, dry eye symptoms are a result of sleeping with your eyes open and lubricants or ointments are very effective for this. It is advisable to use a little amount, just before going to bed.
Surgery may be the solution when the symptoms of dry eye are because the eyelids are in an abnormal position.
In most cases, people with dry eye have discomfort but vision loss.
In severe cases it may be damaged or infected cornea
