As a part of Millennials, I should admit that I spend lots of time on devices. And, I know that it is not a good habit. we need to play more outside. just having a walk, going museums, or having a coffee with your friends. This is a real life. Anyway, Sometimes it is inevitable to avoid using devices. There are some methods to protect better your eyes according to the article from digitaltrends.com. Here you go.

    1. Maintain a comfortable working distance at the computer (close to arm’s length from the screen) and avoid hunching closer and closer.
    2. When using a phone keep the screen as far away from your eyes as comfortably possible — the greater the distance your phone is from your eye, the less eye strain it is likely to cause — provided the print size and images are large enough for comfortable viewing.
    3. Every 20 minutes, take a 20-second break and look off into the distance — at something 20 feet away. This is called the “20-20-20 rule” by many eye care providers, and it relaxes the focusing muscle inside the eye, relaxes the muscles outside the eyes that converge the eyes (points them inward to stay aligned on near objects), and stimulates blinking to remoisten the surface of the eyes — all comforting things!
    4. Get an eye exam. Even minor problems with your eyesight can increase your risk for digital eye strain. Also, ask your eye care professional about the best type of glasses for your digital viewing needs. You might benefit from eyewear specifically prescribed for computer or other digital device use.
    5. Ask your eye care provider about glasses that block blue light. There are a number of brands of eyeglass lenses and coatings that can reduce your exposure to HEV light when using digital devices.
    6. Make sure your eyeglass lenses (if you need them) have an anti-reflective (AR) coating. Eliminating reflections from your lenses can increase viewing comfort and reduce eye strain.
    7. Go outside and play more!
