Rest well is synonymous with a good quality of life. Therefore, sleep disorders can affect many aspects of our health, including vision. This is shown by a part of the 720 people surveyed for the 1st Barometer on Eye Well-being, prepared by Miranza on the occasion of World Sight Day.
Among other things, respondents who sleep less than six hours a day consider their vision worse, compared to those who rest seven hours or more. This group refers symptoms of ocular discomfort that are more pronounced than the average, such as greater sensitivity to light, a sensation of grit, eye discomfort or some difficulty in performing daily tasks, such as reading and using screens. In this sense, although the relationship between vision and sleep is a very broad field: “There is a certain relationship between sleep disorders and certain eye conditions or discomforts, especially dry eyes that should be evaluated by the ophthalmologist”, explains the Dr. Corcóstegui, retina expert, from IMO Grupo Miranza.
Dry eye and sleep
Rest is one of the aspects to which we must pay special attention if we suffer from dry eyes or dry eyes: “First of all, we must bear in mind that this syndrome can cause sleep disturbances, since the eye discomfort it produces, such as feeling of grit, they can make it difficult for us to sleep adequately ”, continues Corcóstegui.
Keep in mind that sleeping well has a regenerative and restorative effect on most of our organs and the eyes are no exception. “In fact, during sleep we also” rest “the ocular surface, closely linked to the quality of our tears”, clarifies the ophthalmologist. In addition, “dry eye is a chronic inflammatory process, which can worsen if we sleep badly because the necessary cell regeneration does not take place so that the tear has all the substances for the correct lubrication of the surface of our eyes”, explains the specialist.

Sleep apnea / hypopnea syndrome (SAHS) is a disease that causes repeated episodes in which breathing stops and air flow is impeded while the person sleeps. At the ocular level, “it is a disease linked to pathologies, some of them serious, such as glaucoma, a group of diseases that cause progressive damage to the optic nerve and whose main risk factor is ocular hypertension”, warns Corcóstegui. According to the ophthalmologist expert, “recent research indicates that people with SAHS have a greater predisposition to develop certain types of glaucoma.”
Similarly, SAHS has also been linked to another condition, in this case, of our eyelids called lax eyelid syndrome. “This is a disorder that seems to occur in 25-40% of people with SAHS, a condition that, in turn, is present in the vast majority of people with eyelid hypermobility,” Corcóstegui continues. However, “the mechanisms that relate both conditions are being studied, as well as the benefit that sleep treatment can have to avoid the resulting symptoms and injuries,” says the expert.
People who feel that their sleep quality is not good or who have noticed changes in rest should be seen by an ophthalmologist
Another disease caused by SAHS is anterior ischemic optic neuropathy (NOIA). “This pathology that is characterized by a sudden loss of vision caused by the interruption of the blood flow that reaches the optic nerve from the head. We could say that it is a kind of ‘heart attack’ ”, continues Corcóstegui.
In conclusion, the expert warns that “if we sleep little and badly, it is likely that, in the long run, we will develop eye disorders or pathologies.” For this reason, it recommends that people who feel that their quality of sleep is not good or who have noticed changes in rest, include the ophthalmologist in their routine of medical check-ups to detect and treat any vision disease in time.
Two out of three people consider that their vision is fair or bad
According to the 1st Barometer of Eye Well-being, carried out by Miranza, two out of three of the people surveyed consider that they have a state between fair and poor vision. The turning point is at age 45, from which time only 24% consider they have good vision, compared to 50% who do between 36 and 45. The same survey has highlighted that Visual problems affect eight out of ten, the most common being refractive errors (myopia, astigmatism and hyperopia) and presbyopia (eyestrain).
What most “bothers” the people consulted is:
- At 54%: Relying on glasses or contact lenses for their daily tasks
- At 26%: The appearance of your eyes: dark circles, eyelids, bulging eyes, etc.
- At 25%: Have less control of what they do because of their sight: reading, working with a computer or night driving, among others
