ophthalmologists from IMO Grupo Miranza warn that 85% of people who sleep little have poor quality sleep or other rest disturbances, such as insomniaThey have dry eye disease. This is one of the conclusions of the Dry Eye Project, a study that the clinic has carried out between 2019 and 2023, in collaboration with AdSalutem (Sleep Institute).
The cornea, ocular surface devoid of blood vessels, is nourished by those found in the upper eyelid (conjunctiva), which allows the tear film to regenerate during sleep. In this way, according to the clinical study, lack of sleep can affect this “tuning up” of the cornea, giving rise to a picture of eye dryness
According to Cecilia Salinas, ophthalmologist at IMO Grupo Miranzaand one of the main researchers of the study, “certain people do not close their eye completely during sleep, leaving it exposed to the outside and, therefore, preventing the eyelid from fulfilling its anatomical function of protect the surface of the eye properly. This fact causes dry eyes to appear or worsen.
Likewise, the specialist warns that this is not the only condition that relates eyelids and dry eye. There is a syndrome known as lax (floppy) eyelidwhich can be easily detected in a routine ophthalmological examination and which is frequently linked to chronic lung diseases, also associated with sleep. When we detect it in the ophthalmological consultation, we recommend that the patient also visit the general practitioner and the oculoplastic ophthalmologist, since, at the same time, it causes poor nocturnal eyelid closure”, explains Salinas.
What causes dry eye?
When dry eye already manifests itself, the discomfort it generates makes it difficult to fall asleep and maintain sleep, which triggers a vicious circle that worsens both rest and dry eyes. In fact, another aspect that the Dry Eye Project highlights is that a greater severity of dry eye is related to poorer sleep quality and efficiency.
Beyond sleep, the IMO Grupo Miranza ophthalmologist recalls that there are other conditions that may be involved in dry eye, such as a multifactorial disease. In this sense, she points out that the most frequent are age, since the incidence increases as we age (especially, in women, following menopause), certain drugs (antidepressants or antipsychotics) and some autoimmune diseasessuch as rheumatoid arthritis or Sjögren’s syndromeclosely linked to dry eye.
