How to Treat Dry Eyes

Is your vision blurry, eyes sore, or feeling dry? Dry eyes can result from the natural aging process, medication, environmental influences, genetic factors, or may even be a symptom of certain health conditions like diabetes or rheumatoid arthritis. Let’s explore how to treat and prevent this condition.

Understand the Importance of Tears. Tears not only keep your eyes moist, but they also serve many other vital functions. They provide essential electrolytes, proteins, and antibacterial enzymes, maintaining eye health. Tears quickly coat your eyes, delivering moisture and nutrients.

• Any issues with the lacrimal glands can cause problems for your eyes. Although there are various causes for dry eyes, some treatments might prove effective.

Use Artificial Tears. Artificial tears are designed to lubricate dry eyes and keep the cornea moist. While they may not cure dry eye syndrome, they help manage the symptoms. Some artificial tears contain preservatives that can irritate your eyes if used more than four times a day. If you need to apply them more frequently, consider using preservative-free artificial tears or consult your doctor.

Try Eye Drops. Hydroxypropyl methylcellulose is one of the most commonly used medications for dry eyes and irritation, followed by carboxymethylcellulose. These act as lubricants in eye drops and are available at many pharmacies. You may also use antibiotic ointments for the eyes such as tetracycline, ciprofloxacin, or chloramphenicol, which are helpful when your eyes are swollen.

Get an Eye Check-up. If your dry eye symptoms persist despite using over-the-counter or prescription eye drops, it's time to see a doctor. After determining the cause of your dry eyes, your doctor will suggest a new treatment plan.

Use Eye Ointment. Your doctor might prescribe an eye ointment. Unlike artificial tears, which address symptoms, eye ointments are used to treat the underlying causes of dry eyes.

Consider Punctal Plugs. For more long-term or severe treatment, your doctor may recommend punctal plugs. These are inserted into your tear ducts to prevent tears from draining, thus maintaining moisture on the surface of your eyes.

Punctal Cauterization. If punctal plugs have been inserted but dry eye symptoms persist, your doctor may recommend punctal cauterization. Once approved, an eye specialist will examine you and perform the surgery.

Take Frequent Breaks When Your Eyes Are Working Hard, Like When Reading or Working on a Computer. Even while reading, resting your eyes is essential. When looking at a screen or a book, we tend to blink less frequently.

Avoid Evaporation. While dry eye cannot be completely cured, preventive measures can help manage the condition alongside treatment. Like all fluids, tears evaporate when exposed to air. To retain moisture in your eyes:

• Avoid direct exposure of your eyes to airflow (such as from car heaters, hairdryers, or air conditioning systems).
• Maintain indoor humidity levels between 30-50%.
• Use a humidifier during winter to add moisture to the dry air in your room.

Wear Glasses. Wear sunglasses when going outdoors. Use protective eyewear when swimming. Your eye doctor may also provide you with special glasses for added protection.

Avoid Irritating Your Eyes. Do not smoke, as it can quickly dry out your tears and lead to other health problems. Also, avoid rubbing your eyes. Rubbing can transfer bacteria from your hands and nails into your eyes.

Consult Your Doctor About Medications That Could Be Causing Dry Eyes. Certain medications like diuretics, antidepressants, beta-blockers, and Parkinson's disease treatments can lead to dry eyes. If you’re using any of these drugs and experiencing dryness, discuss alternatives with your doctor to find medications with fewer side effects.

Ensure Your Contact Lenses Fit Properly. People who wear contact lenses and suffer from dry eyes need to make sure their lenses fit well and that the material and design suit their eyes. It’s best to consult an optometrist for guidance on proper use and to help choose the right lenses for you.

Add Moisture to Your Eyes. Use artificial tears to keep your eyes hydrated and lubricated. You can also use eye ointments for longer-lasting effects, though they may be inconvenient due to their thickness and the potential for blurry vision. Therefore, it’s recommended to use them while sleeping.

• To prevent dry eyes, apply eye drops before engaging in activities that require heavy eye use. Also, make sure to blink frequently to ensure the cornea is properly coated with tears or eye drops.

Modify Your Diet. Dry eyes can result from too much salt in your diet or a lack of essential vitamins. You can check this, especially if you experience dryness upon waking up in the middle of the night. If drinking about 350 ml of water relieves the discomfort, consider cutting down on salt and maintaining good hydration.

• Try increasing the intake of fatty acids, especially omega-3s, which promote tear production and combat dry eyes.
• Ensure you're getting enough vitamin A by eating more plant-based foods like vegetables and fruits. Although vitamin A deficiency is rare in Western countries, it can worsen when a diet lacks sufficient fruits and vegetables.

• Consult a doctor if you experience chronic dry eyes. Chronic conditions like diabetes and high blood pressure require regular eye exams due to potential complications. When dealing with chronic illnesses, it’s important to have a coordinated healthcare team to ensure all your health concerns are monitored and managed.
