If you are constantly rubbing your eyes and you are sleeping enough if your eyes are itchy, if they are swollen and red without a good reason, you may have a dry eye syndrome, which means you do not have enough lubricant (reduced tear) in your eyes to maintain their normal function. Dry eye syndrome may make it difficult for you to focus on subjects, not to mention that it is really unpleasant.
The reasons for this dryness and irritation may be very rare – blinking, occluded ocular glands along the eyelid, aging, systemic illness and medication.
If you have dry eyes you should pay attention, otherwise these symptoms may get worse and even lead to permanent loss of vision, ophthalmologists say.
Here are seven possible reasons for dryness in your eyes and several ways to find relief:
Reason: Environmental conditions
If you live in a lively urban environment, you may be more exposed to pollution and other such factors that can irritate your eyes. In addition, climate and heating installations, the smoky and windy environment also increase the evaporation of tears.
Solution: Use “artificial tear” drops regularly and always wear sunglasses when you are out.
Reason: Contact lenses
If you wear contact lenses instead of glasses, you may be at higher risk of eye dryness. Lenses reduce the oxygen flow to the eye.
Solution: Reduce the time spent wearing contact lenses and never fall asleep with them. Try different types of lenses. Talk to your doctor about what solution to clean the lenses in your case.
Reason: Unhealthy eating
Bad diet affects not only the size of the waist, but may also cause dryness in the eyes. Processed foods high in salt and spirits lead to dehydration of the body. The low omega-3 fatty acid diet is also a risk factor, as foods high in omega-3 help reduce inflammation in the body.
Solution: Increase your omega-3 intake in your diet.
Birth control pills cause dry eyes. Aging also causes a decrease in tear production, so dry eye syndrome is more common in people over 50 years of age. Menopausal women often suffer from dry eyes.
Solution: Use “artificial tears” drops, regularly visit your ophthalmologist, eat foods rich in omega-3.
Cause: Rarely blinking
You probably do not even realize when you blink, but it turns out that the blink frequency is actually very important when it comes to dry eyes. Flashing helps to refresh the tears on the surface of your eyes. The normal flashing frequency is 18 to 20 times per minute. But when you focus on a close subject, such as a screen, the flashing frequency drops to four blinks per minute.
Solution: Take frequent breaks when using digital devices: every 20 minutes, look sideways and blink 20 times to ensure proper tear production.
Antihistamines, antidepressants, all hormonal drugs, attention deficit disorder, acne and high blood pressure can cause dry eyes as they reduce the amount of fluid in the body.
Solution: You can use warm (but not hot) compresses on your eyelids (especially if you have severe pruritus or rosacea).
Dry eyes are a common symptom in people with diabetes. Diabetes can lead to disturbed nervous function throughout the body, especially in the cornea. Moreover, hyperglycaemia (an excess of glucose or sugar in the blood) can increase the number of bacteria on the eyelids and lead to their inflammation.
Solution: Treatment can include diabetes control as well as prescription drugs, artificial tears and omega-3.
