Here are some effective ways to improve and maintain your vision:

Nutrition and Lifestyle

1. Eat a balanced diet rich in eye-healthy nutrients13:

   • Consume fruits and vegetables high in vitamins A and C, such as carrots, spinach, kale, and citrus fruits
   • Include foods with omega-3 fatty acids like salmon, tuna, and halibut
   • Incorporate leafy greens, nuts, and berries for antioxidants

2. Exercise regularly35:

   • Physical activity can lower the risk of conditions that affect vision, like diabetes and high blood pressure
   • Aim for at least 30 minutes of moderate exercise most days of the week

3. Quit smoking or don't start46:

   • Smoking increases the risk of serious eye conditions like cataracts and macular degeneration

4. Maintain a healthy weight2:

   • Being overweight or obese can increase the risk of diabetes and other conditions that may lead to vision problems

Eye Care Habits

1. Practice the 20-20-20 rule47:

   • Every 20 minutes, look at something 20 feet away for 20 seconds to reduce eye strain

2. Wear sunglasses that block UV rays46:

   • Choose sunglasses that block 99-100% of both UVA and UVB radiation

3. Keep your hands clean5:

   • Always wash your hands before touching your eyes, especially when handling contact lenses

4. Use proper lighting for reading and close-up work7:

   • Ensure adequate lighting to reduce eye strain during near tasks

Eye Exercises

While eye exercises won't correct refractive errors, they may help with eye comfort and certain conditions17:

1. Near and far focusing:

   • Alternate focusing on a near object and a distant object for several repetitions

2. Figure eight:

   • Trace an imaginary figure eight with your eyes

3. Palming:

   • Gently cup your palms over closed eyes to relax the muscles around them

Regular Eye Care

1. Schedule regular comprehensive eye exams36:

   • Early detection of eye problems is crucial for maintaining good vision

2. Follow your eye doctor's recommendations6:

   • Wear prescribed corrective lenses as directed
   • Follow treatment plans for any existing eye conditions

3. Protect your eyes during activities4:

   • Wear appropriate protective eyewear during sports or when working with hazardous materials

By incorporating these practices into your daily routine, you can help maintain and potentially improve your vision over time. Remember that while these tips can support eye health, they cannot replace professional eye care or correct existing refractive errors without the help of corrective lenses or surgery.
