Episode: Everything You Need to Know About the Blink Crisis and Dry Eye Disease
Date: January 19, 2026
This episode offers a deep dive into the emerging crisis surrounding decreased blink rates and dry eye disease—especially how modern screen-dominated lifestyles are contributing factors, and what individuals and families can do about it. Dr. Pam Theriot demystifies the science behind blink health, explains how screen use is affecting even young children, provides practical prevention strategies, and emphasizes the restorative power of time outdoors.
Key Discussion Points & Insights
1. The Importance of Eye Health and Common Neglect
- Neglecting Eye Care: Dr. Theriot notes that although people are diligent about dental hygiene, most neglect routine eye care, often only seeking help when problems arise.
"We brush our teeth twice a day every day. Wouldn't dream of going to work without brushing our teeth...And yet if all of our teeth fell out tomorrow, we could just get new ones. And when was the last time that you actually put in effort to take care of your eyes?" (01:33, Dr. Theriot)
- Educational Mission: Dr. Theriot aims to raise awareness through online resources, courses, and self-assessment tools for both parents and screen users.
2. The Blink Crisis: How Screens Are Changing Our Eyes
- Effects of Screen Proximity: Children especially tend to hold screens too close, causing their eyes to grow more nearsighted as a result of increased focusing effort.
"Kids become more nearsighted the closer they hold things to them...We were created to be hunters and gatherers and be outdoors and look far away, not constantly looking at something in front of us." (03:07, Dr. Theriot)
- Reduced Blink Rate:
- Norm: ~21 blinks per minute
- On screens: drops to ~7 blinks per minute
- This cut in blink rate greatly diminishes natural lubrication, risking chronic dryness.
"Screens have this special ability that really trap our attention, and we blink so much less." (03:07, Dr. Theriot)
- Oil Gland Dysfunction:
- Lack of blinking prevents the small meibomian oil glands in your eyelids from secreting healthy oils, leading to solidification ("from olive oil to Crisco").
- Once these glands lose function or atrophy, artificial lubrication may be required for life.
"Using that analogy, we all know that olive oil is healthier than Crisco. So when that oil solidifies, it doesn't come out when we blink...our tears just evaporate even more quickly." (03:07, Dr. Theriot)
3. Self-Assessment and Blinking Exercises
- Inter-Blink Test
- Instructions: Blink several times, keep eyes open, count seconds until discomfort.
- Healthy result: 10+ seconds without discomfort; burning/stinging before that indicates dryness.
"Your tear film should stay full and healthy on the front surface of your eye for at least 10 seconds." (08:26, Dr. Theriot) "If your eyes are starting to sting and burn, your tear film is evaporating...that stinging sensation is an indicator that things are drying out." (09:02, Dr. Theriot)
- The 20-20-20-20 Rule
- Every 20 minutes, take a 20-second break, look 20 feet away, and intentionally blink 20 times.
- Helps refocus eyes and rehydrate tear film.
"After you look away, then take some intentional blinks—three or four really intentional blinks where you're really squeezing." (10:24, Dr. Theriot)
4. Workstation and Home Environment Adjustments
- Micro-breaks & Humidifiers:
- Dr. Theriot recommends frequent short breaks, micro-blinks, and adds that a desktop humidifier can help combat dry indoor air.
"That desktop humidifier, I have one on my desk at home...making some mist into the air. Just keeping the air surrounding your desk more moisturized can really help." (12:28, Dr. Theriot)
- Workstation Setup:
- Screen Distance: Arm's length away or further.
- Screen Position: Lower than eye level to optimize eyelid coverage and reduce evaporation.
- Font/Contrast: Large, clear fonts; high-contrast (e.g., black on white).
- Lighting: Overhead or behind—not directly facing you.
"You should be further than your arm's length or just at your arm's length. It should also be in a downward gaze..." (46:56, Dr. Theriot)
5. Outdoor Time & "Long Distance Looking"
- Eye Relaxation Outdoors:
- Focusing far away outdoors allows eye muscles to fully relax, providing respite from constant near work.
"Our eyes are the most relaxed when we're looking in the long distance." (14:18, Dr. Theriot)
- Light Regulation:
- Sunlight, particularly blue light in the morning, helps regulate circadian rhythms through the eyes.
"Having the blue light on us from the sun stimulates our circadian rhythms and helps us to wake up in the morning and then shut down at the end of the day." (14:48, Dr. Theriot)
- Sleep Disruption:
- Blue light from screens at night impairs natural sleep cycles, since eyes relay time-of-day information to the brain.
"It's not really because that what they were watching was so stimulating. It's the light that is stimulating, not even the content." (17:05, Dr. Theriot)
6. Kids, Gaming, and New Interventions
- Dry Eye Disease in Youth:
- Once rare before age 40, dry eye is now seen equally in males and females under 30—linked directly to increased, early screen exposure.
- Even children as young as two are at risk due to early adoption of tablets/phones.
- "Gamer Kit" and Metaverse Education:
- Dr. Theriot’s clinic created a "gamer kit":
- Lid and lash cleanser (pre-moistened wipes)
- Air-activated warm compress mask (safe for kids)
- Dry eye drink (hydration/mineral supplement)
- Educational efforts extend into the Metaverse via Fortnite integration to teach young gamers self-care routines.
"If we gave our eyes the support that they needed throughout the day, that our eyes would help us to see clearly throughout our workday." (21:19, Dr. Theriot)

7. Treatment & Prevention
- Imaging Oil Glands:
- New technology lets eye doctors visualize meibomian glands, often revealing damage in younger generations.
"More doctors are routinely imaging those oil glands...and so me, myself and my lead technician...I have perfect oil glands...my technician, twenty years younger than me, her oil glands looked like crap." (27:54, Dr. Theriot)
- Point of No Return?:
- Once glands atrophy to "nubs," regeneration is limited. Prevention is easier than correction, though in-office treatments (like IPL light therapy) may help some recovery.
"If we put it [the solidified gland oil] in a frying pan, you can watch it liquefy. That's what the idea of heating is doing." (30:55, Dr. Theriot)
- Daily Eyelid Hygiene:
- Dr. Theriot advocates cleaning lids/lashes nightly with specially formulated wipes—not baby shampoo.
"Having that habit to me even more important than brushing your teeth because you can always get new teeth." (41:50, Dr. Theriot)
8. Advice for Families and Screen Users
- For Young Children:
- Delay prolonged near work/screen use as long as possible; be strict about limiting exposure.
- Keep screens at arm’s length; monitor for creeping closer.
"I will be that annoying. I just push it all the way back to her knees." (44:48, Dr. Theriot)
- For Desk Workers:
- Use posture and ergonomic tips above. Be aware of air flow/dryness, lighting, and font settings.
- For Avid Readers:
- Prefer physical books or non-backlit Kindles/paper-style readers; follow blink and look-away routines; read outdoors when possible.
"The good thing about a book is that it has pages. So there is an endpoint. You could say every four times I turn the page, I take a break." (53:44, Dr. Theriot)
- General Principle:
- Prevention and routine self-care outpace the difficulty of treating chronic dry eye disease later in life.
Notable Quotes & Memorable Moments
- “No one is talking about this, like, don't solidify your eye oil. There should be billboards about this.”
— Ginny Yurich (06:10) - "Every 20 minutes, take 20 seconds to focus your eyes far away...just do that for 20 seconds. But then...take some intentional blinks."
— Dr. Theriot (10:24) - “Just cleansing dirt, dust, debris, pollen from around the eyes, keeping that bacterial load down could really make a big difference.”
— Dr. Theriot (41:50) - "Give them that hydration, give them some vitamins and minerals to help them make a healthy tear film."
— Dr. Theriot (21:19) - “I really can't imagine being in your 30s and then having to deal with issues with your oil glands. You've never even heard of it. You're like, what?”

Conclusion: Takeaways
- Dry eye disease is no longer just an older adult issue—children and young adults are increasingly affected due to screen-based lifestyles.
- Blinking less while using screens disrupts the natural oil and tear balance essential for eye health; solidified gland oil may lead to irreversible problems.
- Prevention is critical:
- Limit or delay screens and near-work for young kids
- Practice lid hygiene and intentional blinking
- Set up work/screen spaces ergonomically
- Spend time outdoors for eye (and overall) health
- Routine, awareness, and practical small steps—like wiping eyelids, taking micro-breaks, and pushing screens further away—can make a lifelong difference.
