In brief: Keep a cool head.
If you are asking as to whether or not sweating can impair your vision during exercise, then the answer is yes.
The effect of the body's sweat is to cool the heat increase generated by exercise. The sweat can be profuse, depending on the ambient temperature and humidity. As it falls into your eyes, a burning and blurring can occur. It would be best to a bandana to absorb the sweat.
