Can dry eyes cause blindness?

Dry eye is a common condition, but can it lead to blindness? While dry eye itself doesn’t usually cause blindness, severe and untreated cases can lead to complications that may threaten vision. Understanding the risks and seeking timely treatment is crucial for maintaining healthy eyes.

How does dry eye affect vision?

Tears are essential for keeping the surface of the eye smooth and clear. When the eyes don’t produce enough high-quality tears, they become dry, irritated, and inflamed. Over time, this can lead to:

• Corneal damage – The cornea, the clear front part of the eye, relies on tears for nourishment and protection. Severe dryness can cause corneal abrasions, ulcers, and even scarring.
• Infections – Tears help wash away bacteria. Without sufficient moisture, the risk of eye infections increases.
• Blurry vision – Chronic dry eye can cause inconsistent tear coverage, leading to fluctuating vision clarity.

Can dry eyes lead to permanent vision loss?

In most cases, dry eye does not lead to permanent blindness. However, extreme cases left untreated can result in:

• Corneal scarring – Severe inflammation and damage can cause scarring that affects vision
• Keratitis – A condition where the cornea becomes inflamed and vulnerable to infection
• Corneal ulcers – Open sores on the cornea that can cause vision impairment if not treated promptly.

When should you seek treatment?

If you experience persistent dry eye symptoms, it’s essential to seek medical attention. Early intervention can prevent complications and help maintain long-term eye health.

Treatment Options for Severe Dry Eye

If you have moderate to severe dry eye, treatments may include:

• Prescription eye drops – These can reduce inflammation and increase tear production.
• Punctal plugs – Tiny devices inserted into tear ducts to prevent tear drainage.
• Moisture goggles – Help retain moisture and protect the eyes in dry environments.
• Specialised in-clinic treatments – Procedures like intense pulsed light (IPL) therapy can help improve tear production.
