Dry Eye Explained

Dry eye is a common condition that affects millions of people worldwide. It occurs when the eyes do not produce enough tears or the tears evaporate too quickly, leading to discomfort, irritation, and even vision problems. In this blog post, we will explore the causes, symptoms, and treatments for dry eye.

Causes of Dry Eye

There are many causes of dry eye, including environmental factors, medical conditions, and medications. Some of the most common causes include:

1. Age: As we get older, the production of tears decreases, leading to dry eye.

2. Hormonal changes: Women are more likely to develop dry eye due to hormonal changes, such as during pregnancy or menopause.

3. Medical conditions: Certain medical conditions, such as autoimmune disorders, diabetes, and thyroid problems, can cause dry eye.

4. Medications: Certain medications, such as antihistamines, antidepressants, and blood pressure medications, can cause dry eye as a side effect.

5. Environmental factors: Exposure to wind, smoke, and dry air can cause dry eye. Also staring too long at monitors and screens.

Symptoms of Dry Eye

The symptoms of dry eye can vary from person to person, but the most common symptoms include:

1. Dryness: The eyes may feel dry, gritty, or sandy.

2. Irritation: The eyes may feel itchy or scratchy.

3. Redness: The eyes may appear red or bloodshot.

4. Blurred vision: Dry eye can cause temporary blurred vision.

5. Sensitivity to light: Dry eye can make the eyes sensitive to light.

Treatments for Dry Eye

The treatment for dry eye depends on the cause and severity of the condition. Some of the most common treatments include:

1. Artificial tears: Over-the-counter artificial tears can help to lubricate the eyes and relieve dryness.

2. Prescription eye drops: In more severe cases, prescription eye drops that increase tear production or reduce inflammation may be necessary.

3. Punctal plugs: These are small devices that are inserted into the tear ducts to help tears stay in the eyes longer.

4. Lifestyle changes: Avoiding environmental triggers, such as smoke or dry air, and staying hydrated can help to relieve dry eye.

5. Surgery: In some cases, surgery may be necessary when the lower eyelid is too loose. This treatment is not very common.

6. Your eyes may also feel better if you:

   • Try to avoid smoke, wind, and air conditioning

   • Use a humidifier to keep the air in your home from getting too dry

   • Limit screen time and take breaks from staring at screens

   • Wear wraparound sunglasses when you're outside

   • Drink plenty of water — try for 8 to 10 glasses every day

   • Get enough sleep — about 7 to 8 hours a night
