What is the best treatment for dry eyes?

Waking up with dry eyes can be incredibly irritating, and persistent symptoms can cause numerous problems. While dry eyes may not cause blindness, it’s important to seek professional help, especially when paired with other symptoms like headaches. But which treatment is best?

Let’s look at the reasons for your dry eyes and how best to treat them.

Reasons for having dry eyes

There are many different reasons why people may develop dry eyes. For some, the symptoms can last a few hours or days, while for others, dry eyes can be a chronic condition that requires treatment.

However, the most common causes of dry eyes tend to be:

• Age.
• Sex.
• The Weather.
• Eye conditions.

Let’s look at each in a little more detail to understand why you may have developed dry eyes.

Age or sex

Dry eyes can become more prevalent as we age, particularly due to natural changes in the tear production system. As we grow older, the body tends to produce fewer tears, and the quality of the tears may degrade, leading to quicker evaporation. This results in insufficient moisture on the surface of the eyes, causing irritation and discomfort.

In women, hormonal changes throughout life can significantly affect tear production. During menstruation, hormonal fluctuations, especially oestrogen, can reduce tear secretion. Pregnancy also introduces shifts in hormone levels that may lead to temporary or prolonged dry eyes. These changes can affect the lipid layer of tears, making them evaporate more quickly.

Menopause, in particular, plays a significant role in causing dry eyes. As oestrogen levels drop sharply, the glands responsible for tear production, particularly the meibomian glands, can become less efficient, leading to a decline in both the quantity and quality of tears. Additionally, the reduced androgens (another hormone affected during menopause) can further impact tear production.

Overall, the combined effect of ageing and hormonal fluctuations in women makes them more susceptible to dry eye conditions throughout their lives.

Weather

Weather conditions can significantly contribute to dry eyes by affecting the moisture levels in the environment, which impacts tear evaporation and eye hydration.

The following types of weather are particularly common causes of dry eyes:

• Dry (low humidity).
• Windy.
• Cold.
• Hot.

Dry, windy, or cold weather can speed up the evaporation of tears, leaving the eyes feeling dry and irritated. Wind can strip away the thin protective layer of moisture that normally coats the eyes, especially in outdoor settings, intensifying symptoms for those already prone to dry eyes.

Low-humidity environments, such as during cold winter months or in air-conditioned or heated indoor spaces, can also cause dry eyes. Heating systems and air conditioners remove moisture from the air, leading to drier surroundings that can dehydrate the eyes more quickly. Similarly, hot, arid climates can exacerbate dry eye symptoms by reducing the natural humidity levels, resulting in faster tear evaporation.

Exposure to intense sunlight or UV rays may also dry out the eyes, as squinting and eye strain contribute to discomfort. Airborne irritants, such as dust and pollen, which tend to be more prevalent in windy or dry conditions, can aggravate the condition by irritating the eye surface. Therefore, environmental factors, especially weather patterns, play a vital role in triggering or worsening dry eye symptoms, although the symptoms are usually temporary.

Eye conditions

Various eye conditions can lead to dry eyes by affecting tear production, tear quality, or the ability of the eyes to maintain sufficient moisture. Some of these conditions interfere with the glands responsible for producing tears, while others cause inflammation or damage to the ocular surface, which can impair tear distribution or increase tear evaporation.

Eye conditions that may cause dry eyes include:

• Blepharitis.
• Meibomian Gland Dysfunction (MGD).
• Sjögren’s Syndrome.
• Allergic Conjunctivitis.
• Corneal Damage (from injury or surgery).

One common issue is blepharitis, which involves inflammation of the eyelids. It disrupts the function of the meibomian glands, responsible for producing the oily layer of tears that prevents them from evaporating too quickly. Similarly, meibomian gland dysfunction (MGD) occurs when these glands are blocked or underperforming, leading to insufficient tear film stability and evaporation.

Autoimmune disorders like Sjögren’s syndrome directly affect the body’s ability to produce moisture, including tears, often causing severe dry eyes. Other conditions, like allergic conjunctivitis, where inflammation occurs due to allergens, can also disrupt the tear film, leading to dryness.

Additionally, corneal damage or surgeries like LASIK can alter the eye’s surface, affecting how tears are produced or distributed across the eye, causing dryness.

How to treat dry eyes

Treating dry eyes involves addressing the underlying causes and improving tear production or retention. Mild cases can often be managed with over-the-counter artificial tears, which help lubricate the eyes and provide temporary relief. These come in various formulations, some designed for long-lasting moisture or to address tear evaporation.

For those with meibomian gland dysfunction (MGD) or similar issues, warm compresses can help unclog the glands and improve tear quality. Regular lid hygiene, using eyelid scrubs, can also reduce inflammation caused by conditions like blepharitis.

In more severe cases, doctors may recommend prescription eye drops such as cyclosporine (Restasis) or lifitegrast (Xiidra), which reduce inflammation in the eyes and increase tear production. Steroid eye drops may be used short-term to control inflammation, but are not a long-term solution due to potential side effects.

For patients with chronic dry eyes, punctal plugs can be inserted into the tear ducts to block drainage, helping retain moisture on the eye surface.

However, if the symptoms of dry eyes occur at specific times only, you can make simple changes to relieve symptoms, such as increasing humidity at home, reducing screen time, and wearing wraparound sunglasses in dry, windy environments can help reduce symptoms.

The best treatment for dry eyes

The best treatment for dry eyes depends on the underlying cause and severity of the condition, as well as individual patient needs. There isn’t a one-size-fits-all solution, but a combination of treatments can provide significant relief. Here’s a breakdown of the most effective treatments for different scenarios.

For mild to moderate dry eyes, over-the-counter artificial tears are typically the first line of treatment. These drops supplement natural tear production and provide immediate relief; you can also choose certain eye drops designed to treat a specific type of dry eye issue. Preservative-free formulas are often recommended for long-term use to avoid irritation from preservatives.

For more chronic dry eye cases, prescription drops are considered highly effective. These medications work by reducing inflammation in the tear glands, promoting better natural tear production over time.

For those whose tears drain too quickly, punctal plugs can be inserted into the tear ducts to retain moisture on the eye surface. This simple, minimally invasive procedure is particularly useful for those with severe dry eyes who do not respond well to drops alone.

For mild cases of dry eyes, most people find simple changes like wearing sunglasses in windy or dry weather, increasing the humidity in the home, increasing water intake or putting a warm compress over their eyes are effective in relieving dry eye symptoms.

Ultimately, the best treatment plan may involve a combination of these methods, personalised to each person’s specific condition and symptoms, with guidance from an eye care specialist.

Can you cure dry eyes?

Dry eyes cannot be completely cured, especially if they stem from chronic conditions such as ageing, hormonal changes, or autoimmune disorders. However, many highly effective treatments can significantly reduce symptoms and improve eye comfort. While dry eyes may persist, the right treatment can provide long-lasting relief.

If one treatment isn’t working, it’s important to remember that different approaches may suit different underlying causes. For example, over-the-counter artificial tears are often the first step, but they may not be sufficient for more severe or chronic cases. In such instances, prescription medications which target inflammation and stimulate tear production might be more effective.

Ultimately, managing dry eyes requires a personalised approach. If your current treatment isn’t providing relief, consult your eye care specialist, as there may be a more suitable alternative that can effectively address your specific condition. Regular follow-ups and treatment adjustments are often necessary to achieve the best outcome.
