7 Simple Ways to Protect Your Eye Health

Your eyes are one of the most valuable organs in your body, allowing you to experience the world around you. However, long hours of screen time, poor nutrition, pollution, and unhealthy habits can increase the risk of eye problems. Fortunately, a few simple lifestyle changes can help keep your eyes healthy and your vision clear.

Here are seven practical ways to protect your eye health.

1. Follow the 20-20-20 Rule

If you spend long hours using a computer, smartphone, or tablet, your eyes can become tired and strained.

Follow the 20-20-20 rule:
