Ever since I got my iphone my eyes have benn red for 4?

Days. It's my first time getting a smart phone and I love how I now have portable device that lets me lay games, go online, even in bed at night. It's like I'm addicted to it and my eyes have never been red for days like this prior to me getting an iPhone.

We have a tendency to blink less when looking at computer screens. Be aware of how often you're blinking because it should happen quite often to moisturize your eyes. You could also buy eye drops that are basically just like tears. Do NOT get visine it's bad for your eyes!

Eye strain. You're probably way too concentrated on what you're doing so you don't blink enough. Because of this, your eyes get dry and red. Take breaks to do something else.

I get that all the time myself usually from my tv. Its due to your focus on one object for an extended period of time without blinking. You blink less when your focused on an object and when your on your phone for over an hour you start to almost get a headache from it and to get red eyes from it that means your probably looking at that screen for at least 3 hours.best thing to do is to close your eyes for 1 minute and for me go outside and let me eyes roam for about 5 minutes.either way 5 minutes per hour will reduce the redness you get from staring at your phone and 10 minutes of relieving your eyes would be even better.

Just like staring at a computer, you need to blink and use eye drops if you need them (liquid preservative free tears, not visine or any of that stuff).
