11 Causes for Dry Eye
What Is Dry Eye?
Dry eye means that your eyes don't have enough lubrication. Other terms for dry eye include dry eye syndrome, dry eye disease, and keratoconjunctivitis sicca.
For many people, it is a chronic condition. For others, it is a temporary symptom of contact use, eye surgery, certain medications, or environment.
Dry eyes can be the result of:
A lack of tear production
Poor quality of tears
Studies estimate that approximately 7 to 33% of people have dry eye symptoms.
11 Common Causes of Dry Eye
Several factors can influence your risk for dry eyes. Generally, women and people over 50 are more likely to develop dry eye syndrome.
The most common causes of dry eye include:
1. Older age
Your tear production declines with age.
In women, hormonal changes that occur with menopause negatively affect tear secretion. In men, a decline in androgen levels with age can cause a decrease in tear production.
2. Female gender
Menopausal and post-menopausal women have a higher risk of dry eyes.
3. Environment and climate
Sunny or windy conditions can trigger dry eyes. Pollution, pollen, dust, and other environmental irritants can also aggravate symptoms.
People living in dry climates are more prone to dry eye than those living in humid climates.
4. Contact lenses
Many people who wear contact lenses also suffer from dry eye.
Affect the quality of your tear film
Restrict oxygen and tear flow
Can trap allergens and irritants in your eye
All of these factors can aggravate dry eyes.

5. Digital devices
Blinking helps your eyes distribute fresh tears.
However, most people who stare at a tablet, phone, or computer screen often do not blink frequently enough while using their device. This causes your eyes to dry out faster.
There are several classes of drugs that can cause dry eyes.
Blood pressure medication
Allergy (antihistamine) medication
Retinoids (such as Accutane).
7. Eye surgery
Laser eye surgery (such as LASIK) and cataract surgery can disrupt the tear film. Post-surgical dry eye is common. Most cases are temporary; others are long-lasting.
8. Systemic conditions
Sjogren's Syndrome is an autoimmune disease that causes dry eyes and dry mouth.
Other conditions frequently associated with dry eye syndrome include:
Blepharitis is when your eyelids are swollen or red. It is usually caused by clogged oil glands.
Entropion is a condition where your eyelid is turned inward. This causes your eyelashes to rub against your eyeball.
Ectropion is a condition where your eyelid turns outward. This leaves your eyes exposed and prone to irritation.
