Nowadays, when the time spent on different screens plays an essential role in everyday life, the term "dry eye syndrome" is often heard.
In the case of dry eye syndrome, there is a dysfunction of the tear film - reduced tear secretion or increased evaporation. The hydration of the eyes is not sufficient, and eye irritation and discomfort occur. In such cases, visual impairment may also occur.
The glands ensure the formation of the tear film's upper or lipid layer on the eyelids' sides.
f eye hydration is not of sufficient quality, eye irritation and discomfort may occur, as well as visual impairment and a higher risk of corneal and conjunctival injuries.
The above symptoms usually worsen in the evening as well as in the morning after waking up.
Tear production and its composition begin to decrease after the age of 40 gradually.
Most often, "dry eye syndrome" can be treated with "artificial tears" - eye drops that are chemically similar to tears and contain the missing nutrients available in different combinations in different eye drops. Eye drops, like a normally functioning tear film, moisturize the eyes, protect them from drying out, reduce friction between the cornea and eyelids, and promote cell regeneration and healing processes.
In severe cases of dry eye syndrome, temporary or permanent occlusion of the tear ducts can be performed by inserting a particular silicone implant into the tear duct to prevent tears from escaping from the eye through the drainage system or by surgically closing them to prevent tears from escaping into the nasal cavity.
Sometimes, we face vision loss due to dry eye syndrome, and it is a misconception that glasses can help improve vision in this case.
However, the function of developing the tear film must be restored before the patient's need for glasses or other vision correction can be assessed.
Furthermore, when the eye's surface is dry, it is impossible to determine what optical power a person requires correctly.
Often, to improve visual acuity, it is enough to restore the tear film, and then it may turn out that glasses are not needed at all.
Prolonged untreated severe dry eye, like any severe eye inflammation, can damage the cornea, increasing the risk of ulceration and scarring of the eye surface, leading to irreversible vision problems.
