Red eyes are annoying and unpleasant. This article will give you tips on what to do if your eyes are irritated and how to fix red sore eyes.
Fix red sore eyes: the causes
Red eyes have different causes. If you know the cause, you can take specific measures against the redness of the eyes.
One cause may be, for example, inflammation of the eyelids by an allergy. A high intraocular pressure reddens the eyelids as well. Ametropia, prolonged wearing of contact lenses, infection of the eye, conjunctivitis or contamination / injury may be the reasons for the redness.
In addition to these medical causes, even a dry ambient air and / or lack of sleep can redden the eyes. Badly applied makeup and mascara can cause the eyes to stick and irritate. Sit on the screen for a long time or rarely blink your eyes too much.
According to the cause, treat your eyes. If you are unsure, consult a doctor. Because the eye is a sensitive organ.
With artificial tears you support your dry eyes with the supply of liquid.
If an allergy has been identified as a cause, antiallergic or cortisone eye drops and eye ointments help. If the doctor diagnoses a bacterial infection he will prescribe you an antibiotic. If you suffer from ametropia, your optician will recommend a correct vision aid with an eye test.
As a contact lens wearer you may suffer from reddened eyes more often. Reduce the wearing time, change the contact lens brand or change the care product.
Causes of dry eye
About 16 percent of the population are affected by the symptoms of dry eye (keratoconjunctivitis sicca), and the trend is rising. In old age the incidence increases, women are more often affected. Characteristic is the disturbed wetting of the ocular surface. This is based on a multifactorial process with inflammatory processes, which can lead to visual disturbances, irritations, inflammation of the connective or cornea and damage to the ocular surface (1, 2). Affected are the ocular surface (cornea, conjunctiva), eyelids, tears and meibomian glands. Ophthalmologists speak of a paradigm shift from the dry to the inflamed eye, even a “clinical picture of chronic pain” (5).
For the function of the sensitive sensory organ eye, the colorless tear fluid for moistening, draining foreign bodies, nutrient supply and killing germs is extremely important. It is evenly distributed by the blink of an eye (every five to ten seconds) and flows out via the tear spot and canal. The tear film consists of three layers:
- The inner mucin layer is formed by the conjunctiva and ensures good adhesion of the tear film to the ocular surface. If this layer is disturbed, the fluid remains insufficient on the eye, and tears flow increasingly.
- The middle aqueous and thickest layer is formed in the lacrimal glands, controlled by the autonomic nervous system. The aqueous phase contains nutrients, oxygen, immunoglobulins and glucose to supply the cornea.
- The outer lipid phase is formed in the meibomian glands. It stabilizes the tear film and prevents the evaporation of the aqueous phase.
The regular eyelid stroke (12 to 20 times / minute) ensures the even distribution of the tear fluid and the release of Meibomsekret. Computer screen work (“office eye syndrome”) and long reading significantly reduce the blinking frequency. The evaporation of tear fluid is increased and the supply to the ocular surface is insufficient.
Hyposecretory or hyperevaporative?
The symptoms of the dry eye are divided into two main forms:
- the hyposecretory form with reduced tear production and predominantly morning foreign body sensation, influenced by season and climate, and
- the hyperevaporative form with disruption of the lipid phase, increased evaporation of the tear film and predominantly evening burning of the eyes.
