Protecting your eyes from mobile and computer screens involves a combination of environmental adjustments, behavioral changes, and regular eye care. First, adjust the brightness and contrast settings on your screens and ensure the room is well lit, but not too bright. Use the 20/20/20 rule: for every 20 minutes of screen use, look at something 20 feet away for 20 seconds to rest your eyes. Regular eye check-ups with your eye care professional can help detect any early signs of eye strain. Lastly, consider investing in computer glasses that filter blue light.
