About 2 years ago, on a dark and rainy night, I made a left hand turn onto a wide, 6 lane avenue that was mostly empty.
I almost hit a man jaywalking in the middle of the street.
He was wearing dark clothes and I absolutely did not see him.
It scared me, because I've never had a problem seeing at night.
So at night, on local streets, I began slowing down when making turns and on curves.
This past spring, the same thing happened, except since I was going slower, there was no way I was going to hit him.
This freaked me out even more, because I'm only 32 yrs old.
So I started doing some research and from diff't resources I started doing a few exercises for my eyes. These have helped a lot and my night vision is close to being what it was a few years ago.
So now I'm going to share what I've done, and I hope this helps others out.
1)Palming my eyes. I cover my eyes with the heels of my hand, forming almost a cup, blocking out any light. I just relax for a minute or 2, and I feel all the tension draining out my eye muscles. I'll also flick my eyes L-R, R-L, up-down, diagonal, for a few reps.
2) As often as possible, I stare off into the distance, as far away as possible. You'll find this also relaxes the eye muscles, and works on long-distance vision.
3) I massage eye muscles on the forehead, above the eyelids, high up on the nose, on the temples. Go light & easy, this will give you a slight headache at first.
4) A quick fix for night vision is turn down your rear-view mirror at night to minimize light bouncing off the mirror into your eyes.
5) Another quick fix, is to look more at the right hand side of the road rather than the middle while driving. The blind spot in your eyes is reduced and you'll be able to focus more.
6) Put a few drops of honey, as natural a honey as possible, into each eye 2x a day. This burns like a mofo the first few times.
There are other exercises, but I haven't tried them consistently.
I hope this helps some of you..
