Dry Eyes: Quick Guide [Everything Essential in 5 Minutes]
Feeling dry, tired, or irritated eyes? Don't have time to read a complete guide? This quick version explains everything essential about dry eyes in 5 minutes: what it is, why it happens, and how to fix it effectively.
What is Dry Eye?
Dry eye is a condition where your tears don't adequately protect your eye surface, causing dryness, irritation, and discomfort.
- Affects millions of people worldwide
- 86% of cases are caused by one specific problem: meibomian gland dysfunction (Craig et al., 2017)
- It's a chronic condition but can be very well controlled with proper treatment
The Mechanism: Why Does Dry Eye Happen?
To understand dry eye, you need to know one key fact:
Your tears have 3 layers:
- Oil layer (lipid) → Prevents tears from evaporating
- Water layer (aqueous) → Hydrates the eye
- Mucin layer → Helps distribute tears
In 86% of cases, the meibomian glands (which produce the oil) get clogged.
When this happens:
- → The oil layer fails
- → Tears evaporate in seconds
- → Your eyes dry up even if they water
This is called "evaporative dry eye" and it's the most common type.
Meibomian Gland Dysfunction (MGD): The Main Cause
What are meibomian glands?
- Small glands located on your eyelid margins
- Each eyelid has between 25 and 40 glands
- They produce the oil that protects your tears
Why do they get clogged?
Over time, the secretions from these glands become thick (like cold butter instead of liquid oil). This clogs the glands and the oil can't come out.
Factors that worsen the clog:
- Age (after 40 years)
- Prolonged screen use (you blink less)
- Hormonal changes (menopause)
- Makeup on the eyelid margin
- Blepharitis (eyelid inflammation)
Do You Have Dry Eyes? These are the 5 Most Common Symptoms:
If you have 3 or more of these symptoms for more than 2 weeks, you probably have dry eyes.

Main Causes of Dry Eyes
Why do I have dry eyes? The most common causes are:
- Meibomian gland dysfunction (86% of cases)
The primary cause - Excessive screen use
Reduces your blink rate from 15-20/min to just 5-7/min - Age
After 50, tear production decreases - Hormonal changes
Menopause: 61% of women have symptoms - Medications
Antihistamines, antidepressants, anti-anxiety drugs

Dry Eye Treatment: Heat Therapy is Key
If you have dry eyes from meibomian gland dysfunction (like 86% of cases), heat therapy can help.
What is Heat Therapy?
It's applying heat to closed eyelids to liquefy the thick secretions from meibomian glands.
How Does It Work According to Scientific Literature?
According to ophthalmology studies (Blackie et al., 2014):
Effective parameters:
- Temperature: 42°C (107.6°F)
- Duration: 10-15 minutes
- Frequency: 1-2 times daily
Mechanism:
- Heat at 42°C (107.6°F) liquefies thick secretions
- Glands can drain properly
- The oil layer of tears improves
- Tear evaporation reduces
Results: Significant improvement in 2-4 weeks with consistent use.
Warm Compresses vs IRIO ONE: The Difference
❌ Homemade Compresses
- Lose temperature quickly
- Don't maintain constant 42°C (107.6°F)
- Don't reach effective 10-15 minutes
- You have to reheat them multiple times
✅ IRIO ONE
- Maintains constant 42°C (107.6°F)
- Exact 15 minutes automatic
- No need to reheat
- Comfortable and easy to use
Many people try applying heat with towels or homemade compresses, but:
- You have to get up every few minutes to reheat them
- You waste 20-30 minutes total (instead of 15 effective minutes)
- It's uncomfortable, frustrating, and doesn't work well
- Eventually, you abandon the treatment
Result: Heat therapy is ineffective because the correct parameters aren't applied consistently.
IRIO ONE: Effective Heat Therapy Following Scientific Parameters
What makes IRIO ONE different?
IRIO ONE is a thermal eye mask specifically designed to apply heat therapy according to parameters described in ophthalmology studies:
- Maintains constant 42°C (107.6°F) throughout treatment
- Exact duration: 15 minutes automatic
- No need to reheat
- Comfortable and easy to use at home
How it follows scientific literature:
Studies show that applying heat at 42°C (107.6°F) for 10-15 minutes helps improve meibomian gland function (Blackie et al., 2014).
IRIO ONE applies exactly these conditions (42°C/107.6°F for 15 minutes) consistently, unlike homemade compresses that lose temperature quickly.
Recommended frequency:
- Moderate cases: 1-2 times daily
- Prevention: 2-3 times per week
⚡ 30-SECOND SUMMARY
The problem:
- 86% of dry eye = clogged meibomian glands
- Tear oil layer fails → rapid evaporation
The solution according to literature:
- Heat therapy: 42°C (107.6°F) for 10-15 minutes
- Liquefies thick secretions
- Glands function better
Why IRIO ONE:
- Homemade compresses lose heat fast ❌
- IRIO ONE maintains constant 42°C (107.6°F) ✅
- Exact 15 minutes, no reheating ✅
Other Complementary Treatments for Dry Eyes
Besides heat therapy, these treatments can help:
- Eyelid hygiene (1-2 times daily)
Clean eyelid margins with special wipes - Preservative-free artificial tears
Relieve symptoms temporarily - Omega-3 (1000-2000 mg/day)
Improve secretion quality - 20-20-20 rule (for screens)
Every 20 minutes, look 20 feet away for 20 seconds

When to See an Ophthalmologist?
Consult if:
- Persistent symptoms for more than 2 weeks
- You need tears more than 4-6 times daily
- Symptoms interfere with your daily life
- Intense eye pain or vision loss
Frequently Asked Questions About Dry Eyes
Can dry eye be cured?
It's not "cured" permanently, but it can be perfectly controlled with treatment. It's like diabetes: it's well managed.
How long does it take to improve?
With consistent heat therapy: 2-4 weeks. With omega-3: 2-3 months.
Are artificial tears enough?
No. They relieve symptoms but don't treat the cause (clogged glands).
Why IRIO ONE and not homemade compresses?
Compresses lose temperature in minutes. IRIO ONE maintains 42°C (107.6°F) for 15 complete minutes, following parameters described in studies.
What is meibomian gland dysfunction?
It's the clogging of glands that produce tear oil. It's present in 86% of dry eye cases.
How many times a day should I use heat therapy?
For moderate cases, 1-2 times daily. For prevention, 2-3 times per week.
Conclusion
What you need to remember:
- 86% of dry eye = meibomian gland dysfunction
- Heat therapy at 42°C (107.6°F) for 10-15 min helps according to studies
- Homemade compresses don't maintain constant temperature
- IRIO ONE applies exact scientific parameters
- Results in 2-4 weeks with consistent use
