Dry eye syndrome is a common but often misunderstood condition that can affect your quality of life and ocular care. Many people experience dry eye symptoms like blurry vision or discomfort. But, they may not realize the potential long-term effects of untreated dry eye.
In this blog, Patrick Frank Albergo MD explores whether chronic dry eye can cause blindness, the causes and symptoms of dry eyes, and why proper care is crucial.
What is Dry Eye Syndrome?
Dry eye syndrome occurs when your eyes don’t produce enough tears or when the tear film—the protective layer that keeps your eyes lubricated—does not function properly. This condition can lead to irritation, discomfort, and potential vision problems if left untreated.
Causes of Dry Eye Syndrome
Several factors can contribute to dry eye, including:
- Meibomian gland dysfunction: Blocked oil glands in the eyelids can lead to insufficient tear film production, which results in dry eye.
- Environmental factors: Exposure to wind, smoke, or dry air can worsen symptoms.
- Prolonged screen time: Reduced blinking while using computers or smartphones can exacerbate dry eye symptoms.
- Contact lenses: Wearing contact lenses for extended periods may contribute to dry eye.
- Aging and medical conditions: Age-related changes, hormonal fluctuations, and conditions like diabetes or autoimmune diseases can reduce the ability to produce enough tears.
Symptoms of Dry Eye Syndrome
Dry eye symptoms can vary in severity and include:
- Blurry vision or difficulty focusing.
- Wateriness, often as a reaction to irritation.
- A burning, stinging, or gritty sensation.
- Redness or inflammation.
- Sensitivity to light.
- Discomfort when wearing contact lenses.
If you experience any of these symptoms persistently, consult a vision care specialist to assess your condition and discuss treatment options.
Can You Go Blind From Dry Eyes?
The short answer is: it’s unlikely, but not impossible. Dry eye syndrome itself doesn’t directly cause blindness. However, chronic or untreated dry eye can lead to complications that may severely affect your vision.
When dry eye symptoms are left untreated, they can escalate into more serious issues:
- Corneal damage: A lack of tear film protection can leave the cornea vulnerable to scratches, ulcers, and infections, which may lead to vision loss.
- Inflammation: Chronic inflammation caused by untreated dry eye can damage tissues, worsening vision problems over time.
- Severe vision problems: In extreme cases, prolonged dry eye syndrome can result in scarring of the cornea, potentially leading to permanent vision loss.
Proper ocular care is essential to prevent long-term issues associated with dry eye syndrome. Regular visits to a vision specialist and early treatment can help manage symptoms and protect your vision.
