Dry eyes

Dry eyes occur when tears do not provide sufficient or adequate lubrication to the surface of the eye. This may be due to insufficient tear production, excessive evaporation or changes in their composition.

Tears are essential for keeping the surface of the eye moisturised and protected. When the tear film is disrupted, discomfort may arise that affects your well-being and, in some cases, the quality of your vision.

Symptoms can vary in intensity and may be occasional or persistent. Common discomforts associated with dry eyes include:

• A feeling of dryness or grit in the eyes.
• Itching, stinging or a burning sensation in the eyes.
• Redness and irritation.
• A sensation of having a foreign body in the eye.
• Eye strain or fatigue.
• Discomfort when using screens for prolonged periods.
• Temporary blurred vision.
• Excessive tearing in response to irritation.

There are various factors that can contribute to the development of dry eyes. Spending many hours in front of a computer, mobile phone or tablet can reduce the frequency of blinking and lead to the evaporation of the tear film.

Other contributing factors include dry environments, air conditioning, heating, wind, smoke, the use of contact lenses, age and certain hormonal changes. Some medicines and health conditions may also be linked to the development of dry eye.

There are various products available for dry eyes that help to moisturise and lubricate the surface of the eye. The most suitable option will depend on the severity and frequency of the symptoms, as well as each person’s individual circumstances.

The available formats include eye drops for dry eyes, artificial tears, ophthalmic gels and specific solutions compatible with certain types of contact lenses.

Artificial tears are one of the most commonly used solutions for relieving the symptoms associated with dry eye. They are formulated to lubricate and moisturise the surface of the eye and temporarily supplement the tear film.

They are available in multi-dose or single-dose formats. Some formulations are preservative-free, which is particularly beneficial when frequent use is required or if there is sensitivity to certain preservatives.

Eye drops for dry eyes provide hydration directly to the surface of the eye. Formulations are available with different ingredients and viscosities to suit varying degrees of dryness.

Among the components commonly used in ocular lubricants is hyaluronic acid, valued for its ability to retain water and promote prolonged hydration of the ocular surface.

Eye gels generally have a more viscous texture than conventional artificial tears, which allows them to remain on the surface of the eye for longer.

Depending on their formulation, they may be suitable when longer-lasting lubrication is required. Some products may cause temporary blurred vision immediately after application, so they should be used in accordance with the manufacturer’s instructions.

Prolonged use of computers and mobile devices can contribute to the development of dry, tired eyes. When we focus on a screen, we tend to blink less frequently, which can increase tear evaporation.

Taking regular breaks, consciously blinking, maintaining a suitable distance from the screen and ensuring that air conditioning does not blow directly onto the eyes are measures that can help improve eye comfort.

People who wear contact lenses may experience a feeling of dryness or discomfort, especially after many hours of wear. There are moisturising eye drops for dry eyes formulated specifically for contact lens wearers.

Not all eye drops can be used whilst wearing contact lenses. Always check that the product explicitly states it is compatible with the type of lens you use.

As well as using lubricating products when necessary, certain daily habits can help reduce the discomfort associated with dry eyes:

• Take breaks when using screens for long periods.
• Blink frequently to help distribute tears.
• Avoid smoke and excessively dry environments.
• Do not direct fans or air conditioning directly at your eyes.
• Maintain good eye hygiene.
• Use contact lenses correctly and adhere to the recommended wearing times.
• Follow your ophthalmologist’s advice if you have persistent dry eyes.
