I am afraid I don' t agree. First of all, you should know the symptoms of dehydrations, including longing for water all the time, dry mouth and swollen tongue, confusion, sluggishness fainting, fainting, inability to sweat and decreased urine output. If you feel pain in your eye, I don' t think it is in relation with dehydration. In order to prevent dehydrating, you need to drink plenty of water every day. Stop taking salt tablets before meals. Do not exercise outdoors when you feel dizzy, that will just accelerate your dehydration. And when you are exercising, remember to wear light colored clothes. I wish these could drive away your doubts, lol.

Signs and symptoms are dry mouth, eyes stop producing tears, which is good to moist eyes. Nausea and vomiting come step by step. All these are basic terms of suffering eye problems. Eye pain cannot be selected out of this list. Eye pain is the first and most prominent sign of getting dehydration. Of course, dry eye comes into being naturally.
