What Is Dry Eye and Why Does It Happen
Dry eye occurs when your tear film, the protective layer that coats your eyes, becomes unstable. Healthy tears are made of three parts: oil, water, and mucus. If one part is out of balance, your eyes can't stay properly hydrated.
Common causes of dry eye include:
- Prolonged screen use or infrequent blinking
- Contact lens wear
- Natural aging, especially after age 40
- Blocked oil glands (also known as meibomian gland dysfunction)
- Dry indoor air and HVAC exposure
- Certain medications or underlying health conditions
It’s not just about how many tears you produce. What matters is whether your tears are doing their job.
Recognizing the Symptoms of Dry Eye
Dry eye can look different for everyone, but most patients notice at least one of the following:
- A burning or stinging sensation
- Gritty or sandy feeling in the eyes
- Redness or irritation, especially later in the day
- Blurry or fluctuating vision
- Excessive tearing (a reflex when the eye is too dry)
- Light sensitivity
- Discomfort while reading, driving, or using screens
Because symptoms often come on slowly, many people brush them off as normal. But at Alderwood Optical and Canyon Park Vision Clinic, we take them seriously, and we’ll help you understand what’s really going on.

Tips for Managing Dry Eye at Home
You can do a lot outside the exam room to reduce dry eye symptoms. These simple strategies often make a substantial difference:
- Blink more often when using screens
- Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds
- Stay hydrated
- Use a humidifier at home, especially during winter
- Wear sunglasses outside to protect from wind and UV exposure
- Clean your eyelids regularly, especially if you wear makeup or contacts
These small adjustments can support the care you receive in the office and help prevent symptoms from returning.
