One thing that happens to me sometimes is bishop blindness. Out of nowhere a bishop just takes a piece of mine. My way of coping with this is just by paying special attention to the opponents bishops, especially if they are near the side of the board where I seem to forget about them more often.
There are techniques for checking for errors before you make your move, and they can help. There was a book published on the topic years ago, but I can't remember the author or the title. I know I bought it, and that I no longer have it, and that I still make blunders.
I noticed that with practice and longer time controls my blunder rate has dropped considerably. I still lose but not because I left queen en prise or some other piece. In fact my OTB and CC chess is considerably higher then my blitz rating. I've also noticed that my blitz has improved from playing at longer time controls more often. You might want to try this.

It's interesting to figure out how the stronger players appear "less" chess blind.
You'll notice that almost ALL of them are extremely obsessive-compulsive about looking at all forcing moves on the board even before they start their move selection process. They also seem to be extremely good at not repeating the same mistakes over and over.
A rigorous thought process of making safety-checks prior to making a move AND looking at every forcing move for both sides (checks, captures, threats) is a must. What's even more important is that you must follow this process EVERY move (not just 8 out of every 10 moves).
I think you just need to lose more games to missed attacks, and it will naturally rise to the top of your thought process 
Momma did always say that if I kept playing with it, I'd go blind -- I didn't know she meant the chessboard!

Same here. I think of it as diagonal blindness, because of the queen's diagonal ability as well. That's a good observation....
Thankyou for all the response.
I have been playing lately in chess.com
I'm back to playing. :)
Practicing calculation will help get rid of chess blindness and improve your board vision. Try Polgar's Chess.
Wear glasses or contacts. Get lasik surgery if you qualify and could afford it.
I'm also very blind sometimes, but this mostly only happens during correspondence chess, like here. I just play more than 1 game at the time, and then it happens to miss some moves, like hanging a piece. I'm trying to lose this blindness, by watching every move from the start again.. this helps for me!
Get some chess glasses.

Here's an excellent tactics training book that focuses on chess blindness specifically from enemy threats on their next move: Looking for Trouble: Recognizing and Meeting Threats in Chess by Dan Heisman.
I think most of the people commenting here don't know what chess blindness is. It is when you are definitely much stronger than you are currently playing, and are failing to see basic capture. Look it up on wiki. It is typically diagnosed when a player suddenly drops one hundred or two hundred points of ability instantly.
I am struggling with this right now. I have been steadily climbing in all metrical standards (tactics trainer, blitz rating, etc.), then everything just stopped working in my mind the way it normally would. It...stinks...
Got to this post searching "why does chess blindness happen" 
It seems even the greatest are not immune:
https://en.chessbase.com/post/chess-blindness-of-the-champions
But i like the idea of slowing it down...
Help. How can I avoid chess blindness?
I can be good at tactics. But often I loose even when I have the advantage just because I dont notice an attack.
Or I dont notice an attack so I quickly start loosing in the start of the game.
Do I just have to practice? What are tips in improoving yourself agaisnt this.
