I started using glasses from last 3 years. when I was not using glasses before three years at least I was trying to read long distance letters. But after wearing of glasses now I can't even recognize the letters, because those are completely blur for me.
I am a great Youtube fan and I came across a video called 'Throw Away Your Glasses' then inspired to do the exercises mentioned in the video. I have attached the video to my post here. If you have more time then read the book 'Take Off Your Glasses and See by Jacob Liberman'
First, Throw away your glasses
Rotating/moving your eyes 10 times in each direction
Moving hand hold object from far to near and focusing on it more while it is coming to you nearer
Bonus Tip: Rub your hands fastly and put your palms on your eyes for every one hour if your job is related to computers
