What most people don’t know about their eyes👀
1. You blink about 15–20 times per minute
That’s over 20,000 blinks a day and every blink cleans and nourishes your eyes.
2. Eye strain isn’t from screens alone
It’s mostly from reduced blinking and prolonged focus not just the screen itself.
3. You don’t use only 10% of your vision
Your brain processes visual information constantly, vision uses a huge portion of brain activity.
4. Good vision doesn’t always mean healthy eyes. You can see clearly and still have glaucoma, early diabetic changes, or retinal issues.
5. Dry eyes can cause excessive tearing. When eyes are too dry, they reflex-tear to compensate, so watery eyes can actually mean dryness.
6. Wearing the wrong glasses can cause headaches and fatigue
Even small prescription errors can strain your eyes and brain over time.
7. Eye problems can signal body diseases. High blood pressure, diabetes, and even brain tumors can first show signs in the eyes.
8. You should still check your eyes even if you see well. Regular eye exams detect silent vision threatening conditions early.
