1. Question 1: 20-20-20 Rule Frequency

   How often should you practice the 20-20-20 rule to help reduce eye strain when using digital screens?

   • Every 2 hours
   • Every 60 minutes
   • Every 20 minutes
   • Once a day
   Show correct answer

   Correct answer: Every 20 minutes

   Explanation: The 20-20-20 rule recommends that every 20 minutes, you look at something 20 feet away for 20 seconds to relax your eyes. This frequency is more effective than once a day, every 2 hours, or every 60 minutes, which do not provide adequate breaks during screen use.

2. Question 2: Preventing Dry Eyes

   What simple habit can help prevent dry eyes while using devices or reading for extended periods?

   • Blinking frequently
   • Wearing contact lenses continuously
   • Staring without breaks
   • Holding your eyelids open
   Show correct answer

   Correct answer: Blinking frequently

   Explanation: Blinking frequently helps keep the eyes moist and reduces dryness. Holding your eyelids open and staring without breaks can worsen dryness, and continuously wearing contact lenses may increase dryness if not managed properly.

3. Question 3: Vitamin for Vision

   Which nutrient is well known for supporting good vision and eye health?

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

   Correct answer: Vitamin A

   Explanation: Vitamin A is essential for maintaining good vision and eye health. While vitamins C, D, and K support different bodily functions, they are not as directly important for eyesight as vitamin A.

4. Question 4: Importance of Sunglasses

   Why is wearing sunglasses important for maintaining healthy eyes outdoors?

   • They help you see better in the dark
   • They increase eye moisture
   • They are only a fashion accessory
   • They protect the eyes from harmful UV rays
   Show correct answer

   Correct answer: They protect the eyes from harmful UV rays

   Explanation: Sunglasses protect eyes from harmful ultraviolet (UV) rays, which can damage eye tissues over time. They do not increase eye moisture, are not just for fashion, and are not intended to help vision in darkness.

5. Question 5: Reducing Eye Strain While Reading

   Which condition should you avoid to help reduce eye strain when reading or using devices?

   • Sitting at a comfortable distance
   • Using proper posture
   • Poor lighting
   • Taking regular breaks
   Show correct answer

   Correct answer: Poor lighting

   Explanation: Poor lighting makes the eyes work harder, leading to strain. Taking breaks, using good posture, and maintaining a comfortable distance from screens all help reduce eye strain rather than cause it.

6. Question 6: Dangers of Rubbing Eyes

   Why is it important to avoid rubbing your eyes frequently?

   • It relieves dryness effectively
   • It improves blood circulation
   • It strengthens eye muscles
   • It can cause irritation and spread germs
   Show correct answer

   Correct answer: It can cause irritation and spread germs

7. Question 7: Hydrating Eyes Naturally

   What daily habit helps keep your eyes naturally hydrated and comfortable?

   • Sleeping less than 5 hours
   • Avoiding carrots
   • Using eye drops regularly without need
   • Drinking enough water

8. Question 8: Recommended Sleep for Healthy Eyes

   How many hours of sleep are generally recommended to promote healthy eyes?

   • 5 hours or less
   • 10–12 hours
   • 2–3 hours
   • Around 7–8 hours
   Show correct answer

   Correct answer: Around 7–8 hours

   Explanation: Adults typically need about 7–8 hours of sleep for healthy eyes. Only 2–3 or 5 hours is insufficient, and 10–12 hours is more than most people require, which may indicate other health issues.

9. Question 9: Screen Setting to Reduce Eye Strain

   Which screen adjustment helps reduce eye strain during prolonged device use?

   • Setting brightness to maximum all the time
   • Adjusting brightness and using night mode or blue light filter
   • Using only small fonts
   • Increasing screen glare
   Show correct answer

   Correct answer: Adjusting brightness and using night mode or blue light filter

   Explanation: Adjusting screen brightness and using night mode or blue light filters reduce strain on the eyes. Increased glare, maximum brightness, or small fonts can actually worsen eye fatigue.

10. Question 10: Eye Exam Frequency

    How often should you have a routine eye check-up for optimal eye health?

    • At least once a year
    • Every 10 years
    • Only if you notice problems
    • Never, if you have no symptoms
    Show correct answer
