Two out of every 10 people in the world are suffering dry eye syndrome, the condition that, if not processed in time, it may be necessary to corneal transplantation, optometrist Leticia Orozco told Efe.
"It's a multifactorial illness which is characterized by decreased tear production or greater evaporation of tear film that causes change visual acuity with possible damage to the surface of the eye, "said the expert.
According to records from the Conde de Valenciana Institute of Ophthalmology, nine out of 10 eye-related patients in Mexico suffer from dry eye syndrome.
"If no appropriate treatment is detected and treated, dry eye syndrome may lead to corneal transplantation, surgical intervention in which the damaged cornea is replaced by a normal cornea," said an expert.
Orozco explained the main symptoms of this disease, burning eyes, excessive tearing, irritated eyes while waking up, and a sense of cutting when working on a computer, watching TV or reading.
"The main thing is that it affects everyday activities, because a person with this disease can be very sensitive to light, stinging, itching, and it impedes their daily activities, such as going to bed at night or reading," he said.
He explained that women are more exposed to this condition, and people from the age of 50 are at greater risk or complications due to diseases such as lupus erythematosus, arthritis, rheumatism and other autoimmune diseases.
The dry eye is associated with the continued use of electronic devices such as tablet PCs, because of the tendency to evaporate more easily, as well as activities that require full attention, as the flashing frequency is lower.
The specialist explained that one could understand that he was suffering from this condition when he did not see so clear, "which indicates that tears are not in good condition," he said.
He explained that it is important to diagnose this disease in a timely manner in order to attack it and prevent more serious consequences.
As the symptoms are usually not precise, the specialist says it's estimated that around 300 million people in the world are currently not diagnosed.
"Citizens are not easy to suspect that they have a dry eye, because they often think that they have tears," he said.
He said that, therefore, many patients often buy lubricants without knowing what and who can influence to be an effective treatment because "no lubricant can be used to prevent discomfort," he said.
Orozco noted that patients with rheumatoid arthritis, diabetes, or hypertension are more likely to suffer from this condition, as some of their medications change the production of tears.
Spending a lot of time in front of a computer or television without flickering can also affect the development of these miseries.
Among the recommendations for prevention, the optometrist said that, in addition to the report, it is important to avoid eye contact with dirty hands every year.
Also, if you often have to work in front of electronic devices, you should try to blink often and use visual correction, such as glasses or contact lenses, and work at a suitable distance.
"It's important that you do not blink, and in your case, the use of artificial tears using electronic devices or tasks that require a fixed glance but always advises a specialist," he concluded. EFE
