“Can dehydration cause blurred vision?”
I am a 34 year old male and I have blurred vision. I wonder if dehydration can cause blurred vision?

While I have not seen any literature about this topic, I do not believe dehydration as many of us experience it, can cause blurring of vision. In its extreme case, it may certainly cause blurred vision as well as blood clotting in blood vessels which have reduced serum and colliding red blood cells.

Yes, but there are many other causes. See a doctor!
Dehydration can cause dryness of the corneas, which can cause blurred vision. Dehydration can also cause metabolic changes in the body that can affect vision.
It would have to be pretty severe dehydration to cause this. Dryness of the eye surface is more common and a more likely cause of intermittent blurry vision. Constant or worsening blurry vision should be checked out with an eye exam.

Yes. A fine water film coats your eyes and makes your vision good
It's possible, but it would come and go, if your vision is blurry all the time then see an Ophthalmologist
