Can Excessive Blinking or Squinting cause you to see spots in your vision?

[WoWBlackWolf]

Can excessive blinking or squniting cause you to see small whiteish purple stationary spots in the center of your vision and see slighlty double vision? this may seem like a dumb question but I am always hyper aware of my vision because I have always had a fear of going blind even though my eyes are fine according to my eye doctor.

No the simplest thing I can say is it doesn't work that way.  Think of it like if you go out on a windy day or dive into a swimming pool you don't set up dangerous shock waves within your body.

Dr. Hagen,

If one has say, drusen, in back of the eye, that is a protuberance below the photoreceptors, would not repetitive blinking produce some kind of pressure wave thru the vitreous?

And this might put a mechanical set of pressure points on the photoreceptors that might in turn produce light?

Lot of conjecting on what might happen in the aging process.

excesisive blinking and squinting will not damage the eye but a eye MD should be consulted to determine why the blinking/squinting
