1. Question 1: Purpose of Tears

   What is the main purpose of tears in your eyes?

   • To improve your sense of taste
   • To help you see in the dark
   • To signal strong emotions
   • To keep the eyes moist, clean, and protected
   Show correct answer

   Correct answer: To keep the eyes moist, clean, and protected

   Explanation: Tears help to keep the eyes moist, wash away dirt, and protect against infections. Improving taste is unrelated to tears, and although emotions can trigger crying, emotions are not the main purpose. Tears do not help you see in the dark.

2. Question 2: Vitamins and Eye Health

   Which vitamin is most commonly linked to good eye health?

   • Vitamin A
   • Vitamin D
   • Vitamin C
   • Vitamin K
   Show correct answer

   Correct answer: Vitamin A

   Explanation: Vitamin A is important for healthy vision and is directly linked to preventing certain eye problems. Vitamins C, D, and K each have health benefits but are not as directly associated with eye health as Vitamin A.

3. Question 3: Effects of Too Much Screen Time

   What can happen if you spend too much time looking at screens without taking breaks?

   • Faster metabolism
   • Eye strain
   • Improved memory
   • Hearing loss
   Show correct answer

   Correct answer: Eye strain

   Explanation: Staring at screens too long can lead to eye strain, which includes symptoms like dryness and fatigue. It does not result in hearing loss, faster metabolism, or improved memory.

4. Question 4: Frequency of the 20-20-20 Rule

   How often is the 20-20-20 rule generally recommended when using screens for long periods?

   • Every 2 hours
   • Before bed only
   • Every 20 minutes
   • Once per hour
   Show correct answer

   Correct answer: Every 20 minutes

   Explanation: The 20-20-20 rule suggests a break every 20 minutes to reduce eye discomfort. Taking breaks once per hour or every 2 hours is less effective, and before bed only does not provide ongoing relief during screen use.

5. Question 5: Focus Target in the 20-20-20 Rule

   What does the 20-20-20 rule suggest you look at during a break from screens?

   • Something 20 feet away for 20 seconds
   • A book for 20 minutes
   • Your hands for 2 minutes
   • The ceiling for 1 minute
   Show correct answer

   Correct answer: Something 20 feet away for 20 seconds

   Explanation: The rule is designed to relax eye muscles by looking at something far away for a short time. Looking at your hands, reading, or staring at the ceiling does not help relax the eyes in the intended way.

6. Question 6: Wearing Sunglasses Outdoors

   Why is it important to wear sunglasses when outdoors on sunny days?

   • To help you hear better
   • To prevent sunburn on the skin
   • To improve night vision
   • To protect the eyes from harmful UV rays
   Show correct answer

   Correct answer: To protect the eyes from harmful UV rays

   Explanation: Sunglasses block UV rays, which can harm your eyes over time. They do not affect hearing, prevent sunburn on the skin (sunscreen helps with that), or improve night vision.

7. Question 7: Eye Specialists

   What is the common name for a doctor who checks your vision and prescribes glasses?

   • Podiatrist
   • Optometrist
   • Dentist
   • Cardiologist
   Show correct answer

   Correct answer: Optometrist

   Explanation: An optometrist specializes in vision care and can prescribe glasses. Dentists care for teeth, cardiologists focus on the heart, and podiatrists treat feet.

8. Question 8: Eye Infection Prevention

   Which daily habit can help reduce the risk of eye infections?

   • Brushing your teeth
   • Washing your hands before touching your eyes
   • Taking cold showers
   • Listening to music
   Show correct answer

   Correct answer: Washing your hands before touching your eyes

   Explanation: Clean hands help prevent transferring germs to your eyes, reducing infection risk. Cold showers, brushing teeth, and listening to music are unrelated to eye infection prevention.

9. Question 9: Sharing Eye Makeup

   Why is it a bad idea to share your eye makeup with others?

   • It will change your hair color
   • It will reduce makeup's effect
   • It might cause sunburn
   • It can spread bacteria and infection
   Show correct answer

   Correct answer: It can spread bacteria and infection

   Explanation: Sharing eye makeup can transfer harmful bacteria, increasing infection risk. It does not affect hair color, cause sunburn, or reduce makeup's effectiveness.

10. Question 10: Supporting Long-Term Eye Health

    What is one simple way to support your long-term eye health?

    • Wearing winter gloves indoors
    • Spending no time outside
    • Regular eye checkups in ophthalmology
    • Avoiding all fruits
    Show correct answer

    Correct answer: Regular eye checkups in ophthalmology

    Explanation: Routine eye checkups help catch vision problems early and support eye health over time. Wearing gloves, avoiding fruits, or never going outdoors do not provide eye health benefits.
