3. Wear Sunglasses: Protect your eyes from UV rays by wearing sunglasses that block harmful rays when outdoors.

4. Practice the 20-20-20 Rule: To reduce eye strain from screens, every 20 minutes, look at something 20 feet away for 20 seconds.

5. Get Regular Eye Exams: Visit an eye care professional for regular check-ups to catch any issues early.

6. Limit Screen Time: Reduce the time spent on screens and take breaks to prevent strain.

7. Exercise Regularly: Maintaining a healthy weight and regular physical activity can help prevent conditions that can affect vision.

8. Quit Smoking: Avoiding tobacco can reduce your risk of cataracts and other eye diseases.

9. Use Proper Lighting: Ensure that you have sufficient and appropriate lighting when reading or working.

10. Consider Supplements: Some studies suggest that specific vitamins and minerals may help with eyesight. Consult with a healthcare provider before starting any supplements.

Always consult with an eye care professional for personalized advice and treatment.
