This questions is answered by me on the other
forum. Pred forte would not cause this. You may need
restasis. You need to be sure that your glasses RX is right especially that the reading segment is strong enough. When you read put drops like BLINK artifical tears in before you read, each 10 minutes look up from your reading, focus on something very far away like down the hall or out a window and make 5-6 very hard, strong blinks.
