What Causes Dry Eye? Aging, Lifestyle, and Long-Term Fixes

Apr 3, 2026

Dry, gritty, irritated eyes aren’t just “part of getting older.” They’re a sign that something’s off and often, it’s fixable. At Big City Optical, we break down the real causes of dry eye and how to treat it for good.

How Age Affects Your Eyes — and Why Dryness Kicks In

As we age, tear production slows down. That means your eyes don’t get the constant coating of moisture they once had, leading to irritation, light sensitivity, and even blurry vision.

Here’s the short version: age can = fewer tears = less protection = dry, uncomfortable eyes.

But age is only part of the story. The quality of your tears can change too especially if your oil glands (called meibomian glands) aren’t doing their job. Without enough oil, your tears evaporate too fast. That’s when you start feeling like there’s something in your eye or experience itching or burning. 

You can begin to experience these symptoms if: 

  1. You’re over 50
  2. You’ve gone through menopause
  3. You have thyroid issues or other autoimmune conditions
  4. You take medications like antihistamines, blood pressure meds, or antidepressants

It’s not your imagination your body really is changing. But dry eye doesn’t have to be your new normal.

Lifestyle Habits That Could Be Making It Worse

It’s not just age. The way we live now, especially in screen-heavy and sleep-deprived times, can absolutely dry out your eyes. Here’s what to watch for:

  1. Screen Time Overload: We blink less when looking at screens, which means fewer chances to spread tears evenly across the eye.
  2. Low Humidity: Whether it’s AC in the summer or heaters in the winter, dry air zaps moisture from your eyes.
  3. Smoking or Secondhand Smoke: It irritates the eyes and damages tear glands over time.
  4. Skincare Products: Some anti-aging ingredients (like retinoids) near the eyes can affect oil gland function.

Even things like your diet and sleep schedule can impact how your eyes feel.

Long-Term Dry Eye Treatment That Actually Works

Dry eye rarely goes away on its own. Each patient’s treatment will be unique and custom to what your eyes need to feel relief that lasts. You’ve got more options than just reapplying eye drops every hour. At [tokens name=’practice’], we take a long-term approach that starts with figuring out what’s really causing your dry eye and then we match you with treatments that make sense for your life.

Depending on what we find during your eye exam, your treatment might include:

  1. Prescription Eye Drops: These go beyond basic artificial tears to reduce inflammation and help you make better tears.
  2. Lid Hygiene & Heat Masks: Great for unclogging those tiny oil glands (especially if you’ve got meibomian gland dysfunction).
  3. In-Office Dry Eye Therapies: We offer treatments in office that help to restore healthy tear production and moisture. 
  4. Punctal Plugs: Tiny plugs inserted into your tear ducts to help keep moisture from draining too fast.
  5. Supplements: Omega-3 fatty acids can help support healthy tear production from the inside out.
  6. Lifestyle Coaching: Tweaks to your screen habits, hydration, or skincare routine can make a real difference.

There’s no one-size-fits-all fix, but we’re here to help you get the relief that lasts.
