My eyes look red and dry after using mobile for a long time. Kindly help.

Hello doctor,

I have red veins in my eyes. It is not that bad when I look in a normal mirror, but I can see the red veins in my eyes when I use a flashlight. They are worse when I use the gadgets. I know it is due to eye strain, but I want to see if it is normal. I need to chat or an optional private online because I live in a province where boats are the only transportation to the mainland. I recently had redness of eyes for two to three weeks last month. It looks clear on seeing, but I can see the redness when I use a flashlight in a mirror. I have some blurry vision and sensitivity to light after someday of having redness. But after some weeks, my sensitivity to light is gone, but I have a sensitivity to brighter lights. But my right eye has redness when I look into some light, and my left eye is normal. I experience some starburst or glare in my right eye. Or maybe I have nearsightedness or farsightedness. I can see red veins on my left eye, which is worse at night or after gaming. I know gaming is so bad and can damage my eyes. Well, I love to, and I always blink and do some eye exercise while gaming or using gadgets. So now you know that this is maybe due to gaming. Can I know if this is normal or how I can treat it? Can eye drops help it? What kind of eye drops I need to use, like my eyes are a bit dry? I can send some pictures. I also see some improvement after I sleep but not that clear. I can still see some red veins.

Please help.
