During the winter months, dry heating air causes problems for many people: the result is drying and irritation of the mucous membranes in the throat and nose area. Dry air can also affect the eyes.
Tears have important functions for our eyes: They form a film that protects the eye and provides it with oxygen and nutrients. This tear film consists of three layers: the inside of the eyelid, the conjunctiva and the cornea, which protect the surface of the eye and ensure good visual function.
When the eye surface becomes dry, it becomes painful and leads to deterioration in visual function. The film also contains germicidal substances that protect the eye from infections. Therefore, dry eyes are at risk of infection. The cornea of the eyes does not have blood vessels that can provide it with oxygen. Instead, it is the tear film that takes oxygen directly from the air and delivers it to the cornea.
Typical symptoms of dry eyes
Dry eyes can have various causes. Also from dry eyes Sikka syndrome It refers to the lubrication disorder on the surface of the eye that occurs due to decreased tear production or increased evaporation of tear fluid. Both events are inflammatory reactions that result in the eye no longer being optimally nourished by tears.
Typical symptoms of an affected eye include:
- eye redness
- foreign body sensation
- itching
- Burn
- Pains
- Cosmetic intolerances
- mucous secretion
- sensitivity to light

- Feeling of pressure in the eye area
The impaired composition of the tear film causes the eye to struggle to supply oxygen to the cornea through the blood vessels in the conjunctiva. The result is red eyes.
How do you treat dry eye?
Ophthalmologists determine the amount of tears using a strip of paper that they hang in the conjunctival sac. Stability can then be measured based on the time between blinking and rupture of the tear film. As a rule, the tear film is then examined under a microscope for changes.
Anyone using eye drops that have a vasoconstrictor effect on red eyes runs the risk of long-term damage to the eye. Therefore, it is recommended to consult a medical professional if symptoms occur over a long period of time. Fresh air and conscious blinking are simple ways to prevent dry eyes.
