Irritation, dryness, or sensitivity to light in your eyes are all symptoms of dry eye syndrome. Let’s delve into dry eye syndrome and explore effective strategies to address it.
What is dry eye?
Dry eye syndrome, also known as dry eye disease, is a common condition characterised by a lack of sufficient moisture and lubrication on the surface of the eye. This occurs when the eyes either do not produce enough tears or when the tears produced are of poor quality. Tears are essential for maintaining the health of the ocular surface, providing lubrication, reducing the risk of infection and ensuring clear vision.
Symptoms of dry eye syndrome
Common symptoms of dry eye include:
- persistent dryness or grittiness in the eyes
- redness and irritation
- excessive tearing or watery eyes
- blurred or fluctuating vision
- sensitivity to light
- feeling like there is something in your eye.
How is dry eye diagnosed?
Diagnosing dry eye involves a comprehensive eye examination. Our optometrists will review your medical history, symptoms and may perform specific tests to assess tear production and quality.
What causes dry eye?
There are various causes of dry eye syndrome. Tear production tends to decrease with age, but exposure to environmental conditions such as dry or windy climates, smoke, dust, or air conditioning, or certain medications, systemic diseases (such as thyroid disorders), and prolonged screen time can all contribute.
Treatment and management for dry eyes
Dry eye treatment aims to alleviate symptoms, improve tear production, and maintain the health of the ocular surface.
Artificial tears
Over-the-counter artificial tear drops can provide temporary relief from dryness and irritation by supplementing natural tear production.
Prescription eye drops
Prescription eye drops may be recommended to reduce inflammation, increase tear production, or improve tear film stability.
Lifestyle modifications
Making lifestyle changes such as using a humidifier, avoiding environments with dry air, and taking regular screen breaks can help.
Eyelid hygiene
Proper eyelid hygiene, including gently cleaning the eyelids and lashes, can help prevent blockage of the oil glands in the eyelids, which contributes to tear film stability.
Nutritional supplements
Omega-3 fatty acids and other nutritional supplements may help improve tear quality and reduce inflammation in the eyes.
