Doctors warn against rubbing the eyes when they feel itchy or dry, without realizing that this behavior may lead to complications that sometimes require advanced treatments such as special medical lenses or even corneal transplantation
Allergies are the most common cause of itchy eyes, especially what is known as "allergic conjunctivitis," which affects the transparent membrane that covers the eye as a result of exposure to allergens such as dust or pollen.
This condition is usually accompanied by redness of the eye, swelling of the eyelids, and constant irritation that causes the person to constantly rub their eyes.
Itching can also result from dry eyes, blepharitis (inflammation of the eyelids), or a feeling of having a foreign object in the eye. In some cases, the cause is irritation of the skin around the eyelid due to environmental factors or contact lens use.
Experts warn that frequent eye rubbing may increase the risk of developing keratoconus, a condition in which the cornea gradually becomes weaker and thinner, leading to a change in its natural shape and blurred vision.
A healthy cornea is round and regular, but as the disease progresses, it becomes more prominent and takes on a cone shape, causing impaired vision.
A treatment known as "corneal cross-linking" is available, which helps strengthen corneal tissue and reduce the deterioration of the condition, but some patients may later need specialized lenses or a corneal transplant in advanced cases.
The damage is not limited to keratoconus; vigorous rubbing can scratch the surface of the cornea, a painful condition that causes blurred vision and requires treatment to prevent infection.
Repeated pressure on the eye can also lead to the rupture of small blood vessels and the appearance of subconjunctival hemorrhage, which makes the eye appear noticeably red, although this condition often disappears spontaneously within days.
Another common problem is the transmission of infections, such as conjunctivitis, also known as "pink eye," especially when touching the eyes with unclean hands.
How can the itching be relieved safely?
Doctors recommend using artificial tears to relieve dryness and irritation, with the possibility of cooling the drops in the refrigerator to increase the feeling of comfort.
Avoiding allergens, such as dust and pollen, also helps to reduce symptoms, along with using cold compresses and appropriate allergy drops.
Experts warn against excessive use of eye drops designed to remove redness, as they only provide temporary relief and may cause side effects over time.
If the itching persists or recurs in a bothersome manner, consulting an ophthalmologist remains the best option to determine the true cause and obtain appropriate treatment.
