If you’ve been experiencing dry eyes, headaches, or blurred vision, it’s crucial not to brush off these symptoms as they could indicate underlying eye problems. An important step in addressing and preventing such conditions is regular eye tests, which can help detect early signs of glaucoma, diabetic retinopathy, and macular degeneration. Additionally, our modern reliance on screens can contribute to digital eye strain, so remember to take breaks and blink regularly to alleviate the strain. Protecting your eyes from harmful UV radiation is also key, and wearing UV protective sunglasses is highly recommended. Furthermore, maintaining a healthy diet rich in vitamins A, C, E, and minerals like zinc can help reduce the risk of sight-threatening diseases such as age-related macular degeneration (AMD). Quitting smoking can also significantly lower the risk of developing eye conditions like AMD and cataracts. And finally, wearing prescribed glasses as recommended by an optometrist and ensuring adequate lighting for reading and working are essential for maintaining clear vision and preventing headaches.

Causes of Dry Eyes

Dry eyes can occur when the eyes do not produce enough tears, when tears evaporate too quickly, or when there are issues with the eyelids. Certain medications and underlying medical conditions can also contribute to dry eyes. Environmental factors, such as dry air or exposure to wind and dust, can further exacerbate the problem.

Dry eyes: Causes, Symptoms, and Treatment Options

Insufficient tear production

One of the primary causes of dry eyes is insufficient tear production. Tears play a crucial role in maintaining eye health by keeping the surface of the eyes moisturized and lubricated. When the lacrimal glands do not produce enough tears, the eyes become dry and irritated. This can be caused by factors such as hormonal changes, aging, certain medications, and medical conditions like Sjögren’s syndrome.

Excessive tear evaporation

Another common cause of dry eyes is excessive tear evaporation. Tears can evaporate more quickly than they are produced, leading to dryness and discomfort. Factors that contribute to excessive tear evaporation include dry or windy environments, air conditioning, excessive screen time, and wearing contact lenses for extended periods without proper lubrication.

Eyelid problems

Issues with the eyelids can also contribute to dry eyes. Malfunctioning eyelids may not spread tears evenly across the surface of the eyes, leading to dry spots. Conditions like blepharitis, meibomian gland dysfunction, and incomplete closure of the eyelids during sleep can all affect the quality and distribution of tears, resulting in dry eye symptoms.

Certain medications

It is important to note that certain medications can cause or worsen dry eyes as a side effect. Medications such as antihistamines, decongestants, antidepressants, hormone replacement therapy, and certain blood pressure medications can all contribute to decreased tear production or increased tear evaporation. If you are experiencing dry eye symptoms, it is essential to consult with your healthcare provider about any medications you are taking.

Medical conditions

Underlying medical conditions can also be responsible for dry eyes. Autoimmune diseases like Sjögren’s syndrome, rheumatoid arthritis, and lupus can affect the tear glands and result in decreased tear production. Other conditions such as diabetes, thyroid disorders, vitamin A deficiency, and certain neurological disorders can also contribute to dry eyes.

Environmental factors

Environmental factors can worsen dry eyes or trigger symptoms in individuals who are already predisposed to the condition. Exposure to dry air, low humidity levels, smoke, wind, and dust can all contribute to increased tear evaporation and dryness. Spending a significant amount of time in air-conditioned or heated environments can further exacerbate dry eyes.

Symptoms of Dry Eyes

Dry eyes can manifest in various ways, and individuals may experience different combinations of symptoms. Some common symptoms of dry eyes include:


The most obvious symptom of dry eyes is a sensation of dryness or grittiness in the eyes. It may feel as though something is in your eye or that your eyes are not properly hydrated.


Dry eyes can cause eye irritation. You may experience a constant itching or burning sensation that is difficult to alleviate.


Redness of the eyes is a common symptom of dry eyes. The blood vessels on the surface of the eyes may become more prominent, giving the eyes a bloodshot appearance.

Burning sensation

A burning sensation in the eyes is often associated with dry eyes. It can be uncomfortable and may worsen with prolonged screen time or exposure to dry or dusty environments.

Blurred vision

In some cases, dry eyes can lead to blurred vision. Vision may temporarily become unclear, making it difficult to focus on objects or read text.

Sensitivity to light

Dry eyes can also cause increased sensitivity to light, known as photophobia. You may find it uncomfortable to be in brightly lit environments or to be exposed to sunlight.

Diagnosing Dry Eyes

If you are experiencing symptoms of dry eyes, it is important to consult with an eye care professional to receive a proper diagnosis and appropriate treatment. The following methods may be used to diagnose dry eyes:

Symptom evaluation

During a comprehensive eye examination, your doctor will evaluate your symptoms and discuss your medical history. They may ask about any medications you are taking and any underlying medical conditions that could contribute to dry eyes.

Tear film evaluation

Your eye care professional may conduct tests to evaluate the quality and quantity of your tears. These tests can measure tear production, tear stability, and the rate of tear evaporation.

Schirmer’s test

The Schirmer’s test involves placing a small strip of filter paper under your lower eyelid to measure the amount of tears your eyes produce over a certain period. This test can help determine whether your tear production is within the normal range.

Fluorescein and Lissamine Green dyes

Fluorescein and Lissamine Green dyes can be used to observe any damage or staining on the surface of the eyes. These dyes are applied to the eyes and can highlight areas of dryness or damage.

Meibomian gland evaluation

The meibomian glands in the eyelids produce the oils that are essential for preventing tear evaporation. Your eye care professional may evaluate the function and structure of these glands to determine if they are contributing to your dry eye symptoms.

Corneal and conjunctival staining

Staining with special dyes can help identify areas of the cornea and conjunctiva that have been damaged due to dryness. This can provide further insight into the severity of your dry eye condition.

Consequences of Untreated Dry Eyes

If left untreated, dry eyes can lead to various complications that can impact your eye health and overall quality of life. Some potential consequences of untreated dry eyes include:

Corneal damage

Continuous dryness and friction on the surface of the cornea can lead to corneal damage. The cornea may become inflamed, scratched, or develop corneal ulcers, which can affect your vision and require additional treatment.

Increased risk of eye infections

Dry eyes can make the eyes more susceptible to infections. Without adequate tear production and lubrication, the eyes are unable to effectively flush out harmful bacteria and foreign particles, increasing the risk of developing eye infections such as conjunctivitis.

Decreased quality of life

Untreated dry eyes can significantly impact your quality of life. Chronic dryness, discomfort, and irritation can affect your ability to work, read, drive, and perform daily activities. It can also interfere with your sleep and overall well-being.

Difficulty performing daily activities

Severe dry eyes can make it challenging to carry out everyday tasks that rely on clear vision. Your ability to read, drive, use electronic devices, and engage in hobbies that require visual acuity may be impaired.

Treatment Options for Dry Eyes

Fortunately, there are several treatment options available to manage and alleviate dry eye symptoms. The appropriate treatment plan will depend on the underlying cause and severity of your condition. Some common treatment options include:

Artificial tears

Artificial tears are over-the-counter eye drops that can help supplement natural tear production and provide temporary relief from dryness and irritation. They can be used as needed throughout the day or as directed by your eye care professional.

Prescription eye drops

In more severe cases of dry eyes, your eye care professional may prescribe medicated eye drops. These prescription eye drops may contain anti-inflammatory agents or medications that help stimulate tear production.

Lifestyle changes

Making certain lifestyle changes can help manage and prevent dry eyes. This may include taking regular breaks from screen time, maintaining a healthy diet, staying hydrated, and avoiding smoke and allergens.

Punctal plugs

Punctal plugs are small devices inserted into the tear ducts to help block the drainage of tears. By keeping tears in the eyes for a longer period, punctal plugs can help increase tear retention and alleviate dry eye symptoms.

Thermal pulsation treatment

This treatment involves the application of heat and gentle massage to the eyelids to help improve the function of the meibomian glands, which are responsible for producing the oils that protect the tear film. By stimulating the glands, thermal pulsation treatment can help alleviate dry eye symptoms.

Intense pulsed light therapy

Intense pulsed light therapy is a non-invasive treatment that uses pulses of light to heat and shrink the abnormal blood vessels on the eyelids, resulting in improved function of the meibomian glands. This therapy can help reduce dry eye symptoms and improve overall eye health.

Oral medications

In some cases, oral medications may be prescribed to manage underlying medical conditions that contribute to dry eyes. These medications may help improve tear production or alleviate symptoms associated with certain autoimmune diseases.

Eyelid hygiene

Maintaining good eyelid hygiene is essential for managing dry eyes. This may involve regularly cleaning the eyelids and lashes with a gentle cleanser, using warm compresses to soothe the eyes, and avoiding rubbing or touching the eyes excessively.

Preventive Measures for Dry Eyes

While treatment options are available, it is always better to prevent dry eyes from occurring in the first place. Consider the following preventive measures to reduce the risk of developing dry eyes:

Dry eyes: Causes, Symptoms, and Treatment Options

Blinking regularly

When focusing on tasks like reading or using electronic devices, it is common to blink less frequently. However, consciously making an effort to blink regularly helps distribute tears across the surface of the eyes, preventing dryness.
