Everyday Habits That Quietly Harm Your Eyes (Without You Realizing It)

Hi everyone, this is EFE Glasses. After helping thousands of customers choose lenses and understand their eye needs, we’ve seen one thing over and over: most eye discomfort doesn’t come from “bad eyesight”—it comes from everyday habits that slowly strain your eyes without you noticing.

Dry eyes, increasing myopia, eye pressure, headaches, blurry vision… These problems often develop from small behaviors we repeat daily.

Today, based on optical knowledge and years of real customer experience, we’re breaking down the most common hidden eye-damaging habits—and what you can do to protect your vision.

1. Staring at Screens Without Blinking Enough

When you focus on your phone or computer, your normal blink rate (15–20 times/min) drops to under 5 blinks per minute. This makes tears evaporate faster and causes:

• dryness

• burning sensation

• soreness

• blurry vision

Many EFE Glasses customers notice an improvement when using blue light glasses, but no lens can replace healthy habits.

Simple fix — the 20-20-20 rule:
Every 20 minutes, look 20 feet (≈6 m) away for 20 seconds.

It’s one of the easiest and most effective eye-care tips.

2. Watching Screens in the Dark

Scrolling before bed in a dark room is extremely common, but incredibly tiring for your eyes.
Your pupils constantly adjust between bright screens and a dark environment, forcing your eyes into a state of constant tension.

This often leads to:

• nighttime eye soreness

• difficulty focusing in the morning

• headaches

EFE Glasses recommends:

• Keep the room softly lit while using screens

• Reduce screen brightness in dark conditions

• Avoid using your phone under a blanket or with lights completely off

Your eyes work hard—even when you feel relaxed.

3. Using Your Phone While Lying Down

Whether on your side, face down, or half-reclined, this habit is more harmful than it seems.

Different distances between each eye and the screen can cause:

• uneven focus load

• unequal myopia development

• poor binocular coordination

We’ve helped many customers who developed unequal prescriptions largely due to this habit.

Better habit:
Sit upright with your screen 33–40 cm away.

4. Staying Too Long in Air-Conditioned Rooms

Air conditioning reduces humidity, causing tears to evaporate faster. This is a major reason office workers experience dry eyes or feel like their “vision is getting worse.”

Tips from EFE Glasses:

• Blink consciously when working

• Use preservative-free artificial tears

• Add humidity (cup of water or humidifier)

• Wear blue light glasses during long computer use

Dry eyes often mimic myopia symptoms—but require different solutions.

5. Ignoring Warning Signs from Your Eyes

Eye discomfort doesn’t mean your eyes are “tired”—it means something is wrong.

If you frequently experience:

• pressure behind the eyes

• headaches

• distance blur

• double vision

• needing to blink repeatedly to refocus

These are early signs of eye strain.

Ignoring these signals increases the risk of faster myopia progression or worsening astigmatism.

Early awareness = long-term protection.

6. Wearing Old Glasses Without Updating Your Prescription

Many customers tell us:
“I can still see okay, so I didn’t replace my glasses.”

Old prescriptions cause:

• constant over-focusing

• eye fatigue

• headaches

• blurry distance vision

• worsening myopia

EFE Glasses recommends:

• Adults: update every 12 months

• Students/teens: every 6 months

A correct prescription is one of the strongest forms of eye protection.

7. Overwearing Contact Lenses Beyond the Recommended Time

Daily lenses worn for a week…
Two-week lenses used for a month…

We’ve seen it all—and the consequences include:

• red eyes

• corneal inflammation

• infections

• keratitis

Contact lens schedules are designed for eye safety, not marketing.
Saving money by overwearing them is never worth the risk.

8. Treating Eye Redness or Minor Injuries Casually

“Just a little red.”
“It’ll get better after sleeping.”
“These eye drops will fix it.”

These assumptions delay treatment and can worsen underlying conditions.

If you notice:

• persistent redness

• pain

• sudden blur

• flashes of light

• foreign-body sensation

Please treat it as an eye emergency, not a minor inconvenience.
