“Give your eyes a break.
Do you spend a lot of time looking at a computer, phone, or TV screen? Staring at any one thing for too long can tire your eyes. Give your eyes a rest with the 20-20-20 rule: Every 20 minutes, look about 20 feet away for 20 seconds.
Speak up if your vision changes.
Is your vision blurry? Do you squint a lot? Ever have trouble seeing things at school? Tell a parent or teacher if your eyes are bothering you or if you notice any changes in your vision.
Eat right to protect your sight.
Keep your eyes healthy by eating a well-balanced diet. Load up on different types of fruits and veggies, especially leafy greens like spinach, kale, and collard greens. Fish like salmon, tuna, and halibut have been shown to help your eyes, too.“
