Dry eye is a common ocular disease characterized by the inability of the ocular surface to remain sufficiently lubricated, resulting from insufficient tear production or a deterioration in tear quality. The answer to the question, “What causes dry eye?” is generally related to factors such as the lacrimal glands not producing enough tears or the rapid evaporation of existing tears.

What Causes Dry Eye?
There are various causes of dry eye, and these can differ from person to person. We answered “What is dry eye?” in the previous section. The answer to “What causes dry eye?” is generally related to decreased tear production, increased tear evaporation, and environmental factors.
The most common causes of dry eye include:
- Decreased tear production: One of the main reasons for needing to use drops for dry eye is that the lacrimal glands cannot produce enough tears. In response to “How is dry eye diagnosed?”, symptoms of dryness in the eye include burning, a gritty sensation, and blurred vision.
- Increased tear evaporation: Treatment options such as dry eye drops contain components that prevent evaporation. Factors like digital screen use, windy and dry weather conditions, or artificial environments with air conditioning and heaters can cause tears to evaporate rapidly.
- Environmental factors: External factors such as air pollution, cigarette smoke, prolonged time in front of a screen, and low humidity can cause symptoms of dryness in the eye, including itching, ocular redness, and a feeling of fatigue.
- Hormonal changes: How can dry eye be helped? Dry eye is frequently seen in women, with a female-to-male ratio of 4:1. It particularly affects those experiencing pregnancy, menopause, or thyroid problems. For those seeking a natural solution for dry eye, foods containing Vitamin A and omega-3 can support hormonal balance and protect eye health.
- Autoimmune diseases: Immune system disorders such as Sjögren’s syndrome, rheumatoid arthritis, and lupus are among the conditions that may require treatment for severe dry eye.
- Use of certain medications: Antihistamines, decongestants, antidepressants, birth control pills, and blood pressure medications are other answers to the question, “What causes dry eye?”. These drugs can reduce tear production, increasing the need for dry eye treatment.
Harms of Dry Eye
If not treated in a timely manner, dry eye can have serious negative effects on ocular health. The harms of dry eye are not limited to immediate discomfort; they can progress to long-term permanent damage to the ocular surface and even vision loss.
- Ocular Surface Damage and Risk of Infection
- Constant Discomfort and Decrease in Quality of Vision
- Corneal Ulcers and Scarring
- Other Health Problems Associated with Dry Eye
For these reasons, applying appropriate treatment methods such as eye drops for dry eye and laser therapy is of great importance. Protecting eye health is possible with early diagnosis and correct treatment.
Symptoms of Dry Eye
The symptoms of dry eye can vary from person to person, but commonly include a burning, gritty, or itching sensation in the eyes, ocular redness, blurred vision, sensitivity to light, a feeling of eye fatigue, accumulation of stringy mucus in or around the eyes, discomfort when wearing contact lenses, and difficulty with night driving.
These symptoms can be mild or severe depending on the severity of the dry eye and can negatively affect daily life activities.
What Should We Pay Attention To?
It is recommended that individuals experiencing dry eye take the following precautions:
- Increase Environmental Humidity: Use humidifiers to increase the moisture level indoors.
- Reduce Screen Time: Avoid looking at computer and phone screens for long periods and rest your eyes at regular intervals.
- Remember to Blink: Try to blink more consciously, especially when in front of a screen.
- Use Protective Eyewear: Protect your eyes from environmental factors by using protective glasses in windy or dusty environments.
- Eat a Balanced Diet: Consume foods rich in omega-3 fatty acids and Vitamin A.
These measures can help alleviate the symptoms of dry eye. However, if symptoms persist, an ophthalmologist should be consulted.
Dry Eye Treatment
The treatment for dry eye varies depending on the underlying causes and the severity of the symptoms. Common treatment methods include:
- Artificial Tears: Over-the-counter artificial tear drops can be used to compensate for the lack of tears.
- Prescription Medications: Prescription eye drops that increase tear production or reduce inflammation may be recommended by a doctor.
- Punctal Plugs: Small plugs can be placed in the tear ducts to allow tears to remain on the eye for a longer period.
- LipiFlow and IPL Therapies: Thermal and light therapies can be applied to improve the function of the eyelid glands.
The treatment plan should be determined by an ophthalmologist based on individual needs. While natural methods can alleviate the symptoms of dry eye, a consultation with an ophthalmologist is essential for chronic and progressive cases.
Foods That Are Good for Dry Eye
Certain foods are recommended to protect eye health and support tear production. Foods that are good for dry eye include:
