What Causes Dry Eye?

Feb 1, 2025 | Dry Eye

Dry eye is a common issue that can make your eyes feel scratchy, irritated, and uncomfortable, almost like there’s sand in them. You might notice redness, itchiness, or even excessive watering as your eyes try to compensate for the dryness. Sometimes, your vision can become blurry, making it difficult to focus on daily tasks.  

So, what could be causing all of your dry eye symptoms? Figuring out why your eyes feel dry is the first step to getting some relief. The following are some factors that may contribute to dry eye: 

Meibomian gland dysfunction 

One often overlooked cause of dry eye is meibomian gland dysfunction (MGD). The meibomian glands, located along the edges of your eyelids, produce an oily layer that prevents tears from evaporating too quickly. When these glands are blocked or not functioning properly, the tear film becomes unstable, leading to dry eye symptoms. MGD is very common and can be managed with warm compresses, lid massages, and specific treatments recommended by your eye care professional.  

Aging 

As we age, our bodies undergo various changes, including a natural decrease in tear production. If you’re noticing more dryness, especially if you’re over 50, it could be due to the natural aging process.  

Hormonal changes 

Hormonal changes can significantly impact tear production, particularly for women. Pregnancy, menopause, and birth control pills can alter your body’s chemistry, sometimes leading to dry eye.  

Environmental factors 

Your environment can have a significant impact on your eye health. Spending a lot of time in air-conditioned or heated spaces, or being exposed to wind or smoke, can cause tears to evaporate more quickly. Additionally, long hours in front of computer or phone screens can reduce how often you blink, contributing to dryness. 

Medical conditions and medications 

Certain medical conditions can affect tear production. Autoimmune diseases like Sjögren’s syndrome, rheumatoid arthritis, and lupus can interfere with tear production. Conditions such as diabetes and thyroid disorders are also known to have an impact. Furthermore, many common medications, including antihistamines, decongestants, and antidepressants, may cause dry eyes as a side effect. If you think your medications might be part of the problem, talk to your doctor about solutions.  

Lifestyle choices 

Lifestyle choices can also play a part. Smoking, for example, is a known risk factor for dry eye. Not drinking enough water can lead to dehydration, affecting tear production. Staying hydrated and making healthy lifestyle choices can help alleviate dry eye symptoms. 

Contact lens wear 

If you wear contact lenses, they can sometimes contribute to dry eye. Contacts can interfere with the natural tear film, causing it to evaporate more quickly. If your eyes constantly feel dry and irritated while wearing contacts, it might be time to visit our eye doctors in Pembroke Pines. We can recommend different types of lenses or solutions to help you keep your eyes lubricated and comfortable throughout the day.
