Dry eyes is a common condition that affects many people, especially as they get older. It occurs when the eyes do not produce enough tears or the tears evaporate too quickly. This can cause discomfort, irritation, and vision problems. In this blog post, we will explain what causes dry eyes, what are the symptoms, and how to treat and prevent it.

What Causes Dry Eyes?

The eyes need a thin layer of tears to stay moist and healthy. This layer, called the tear film, has three components: oil, water, and mucus. Each component has a specific function:

• • The oil layer prevents the tears from evaporating too fast and keeps the tear surface smooth. It is produced by the meibomian(oil producing glands) glands in the eyelids.

• • The water layer cleans the eye and washes away foreign particles. It is produced by the lacrimal glands in the eyelids.

• • The mucus layer helps the tears spread evenly over the eye and keeps them from drying out. It is produced by the conjunctiva, the clear tissue that covers the white of the eye and the inside of the eyelids.

Dry eyes can occur when there is a problem with any of these components. For example, the meibomian glands may become blocked or inflamed, reducing the amount or quality of oil in the tears. The lacrimal glands may produce less water due to aging, hormonal changes, or certain medications. The conjunctiva may produce less mucus due to allergies, infections, or autoimmune diseases.

Some other factors that can contribute to dry eyes include:

• • Environmental conditions, such as dry, windy, or smoky air, or exposure to air conditioning or heating.

• • Lifestyle habits, such as staring at a computer screen, reading, or wearing contact lenses for long periods of time, which can reduce the blinking frequency and tear production.

• • Certain diseases, such as rheumatoid arthritis, Sjögren’s syndrome, thyroid disease, and lupus, which can affect the immune system and the tear glands.

• • Eye surgery, such as LASIK or cataract surgery, which can temporarily or permanently alter the tear film and the cornea, the clear front surface of the eye.

What Are the Symptoms of Dry Eyes?

Dry eyes can cause a variety of symptoms, such as:

• • A burning, stinging, or scratchy sensation in the eyes

• • A feeling of having something in the eyes, such as sand or dust

• • Redness, irritation, or inflammation of the eyes or eyelids

• • Blurred vision or difficulty focusing, especially after prolonged periods of visual activity

• • Sensitivity to light or glare

• • Watery eyes, which is the body’s response to the irritation of dry eyes

• • Difficulty wearing contact lenses or eye makeup

• • Eye fatigue or strain

The symptoms of dry eyes can vary from person to person and may change depending on the situation. They may be worse in the morning, evening, or during certain seasons. They may also be affected by the type of activity, such as reading, driving, or watching TV.

How to Treat Dry Eyes?

The treatment of dry eyes depends on the underlying cause and the severity of the condition. Some common treatments include:

• • Artificial tears, which are eye drops that can supplement the natural tears and lubricate the eye. They are available over-the-counter or by prescription, and come in different types and formulations. Some artificial tears contain preservatives, which can be irritating for some people, while others are preservative-free and come in single-use vials. Some artificial tears also contain ingredients that can help reduce inflammation or improve the quality of the tear film. Artificial tears can be used as needed, but they may not be enough for severe cases of dry eyes. (You may check out some of the Lubricating/Artificial tears at the bottom of this page)

• • Eye ointments, gels, or inserts, which are thicker and more viscous than artificial tears and can provide longer-lasting relief. They are usually applied at night, before going to bed, as they can blur the vision. They can also be used in combination with artificial tears during the day.

• • Punctal plugs, which are small devices that are inserted into the tear ducts, the openings at the inner corners of the eyes that drain the tears into the nose. By blocking the tear ducts, punctal plugs can help retain more tears on the eye surface and reduce dryness. Punctal plugs can be temporary or permanent, and can be easily removed or replaced by an eye doctor.

• • Prescription medications, such as cyclosorine , which are eye drops that can help reduce inflammation and increase tear production. They are usually used for chronic or severe cases of dry eyes that do not respond to other treatments. They may take several weeks or months to show their full effect, and they may have some side effects, such as burning, stinging, or redness of the eyes.

• • Lipiflow, which is a device that uses heat and pressure to unclog the meibomian glands and improve the oil flow in the tears. It is a procedure that is performed by an eye doctor in the office, and it takes about 15 minutes per eye. It may provide lasting relief for some people with dry eyes caused by meibomian gland dysfunction.

• • Intense pulsed light (IPL), which is a treatment that uses pulses of light to target the blood vessels and inflammation around the eyes. It can help reduce the symptoms of dry eyes caused by rosacea, a skin condition that affects the face and the eyes. It is a procedure that is performed by an eye doctor or a dermatologist, and it may require several sessions to achieve the desired results.

• • Other treatments, such as omega-3 fatty acid supplements, autologous serum eye drops, scleral lenses, or surgery, which may be recommended for some specific cases of dry eyes that do not respond to conventional treatments. These treatments should be discussed with an eye doctor before trying them.

How to Prevent Dry Eyes?

Some lifestyle changes and preventive measures can help reduce the risk or the severity of dry eyes, such as:

• • Avoiding or limiting exposure to dry, windy, or smoky environments, or using a humidifier to add moisture to the air

• • Wearing sunglasses or protective eyewear to shield the eyes from the sun, wind, or dust

• • Taking breaks from reading, working, or watching screens, and blinking more often to moisten the eyes

• • Drinking enough water and eating a balanced diet that includes foods rich in omega-3 fatty acids, such as fish, nuts, and seeds

• • Cleaning the eyelids and eyelashes regularly with warm water and a gentle cleanser to remove any debris or bacteria that can cause inflammation or infection

• • Using eye drops or artificial tears before or after activities that can dry out the eyes, such as flying, swimming, or wearing contact lenses

• • Following the instructions and recommendations of the eye doctor regarding the use, care, and replacement of contact lenses or eye medications

• • Having regular eye exams and check-ups to monitor the eye health and the tear function

Dry eyes is a common and treatable condition that can affect anyone at any age. By understanding the causes, symptoms, and treatments of dry eyes, and by taking some preventive steps, you can improve your eye comfort and your quality of life. If you have any questions or concerns about dry eyes, or if you experience any persistent or severe symptoms, you should consult your eye doctor for a proper diagnosis and treatment.
