You need to use the eyes drops to moisture the eyes and use the warm compress to make your eyes feel comfortable.
Dehydration is often defined as the excessive loss of body water, with an accompanying disruption of metabolic processes. Symptoms may include headaches, decreased blood pressure, and dizziness or fainting when standing up due to orthostatic hypotension.

Mild dehydration won't cause blurred vision, but i am sorry to tell you that you will not only get blurred vision but also lose your marbles easily if you get severe dehydration.

Please attach enough importance to dehydration.
