Not Drinking Enough Water
Not drinking enough water daily, alongside eating a high-sodium diet can cause dehydration which eventually causes the eyes not to produce enough tears to keep the eyes moist and properly nourished. This in turn leads to dry eyes, redness and puffy eyelids.
Too Much Screen Time
Too much screen time tends to slow your blinking rate which eventually causes dry eyes and smeary vision. It can additionally make the eyes burn and water. Make it a point of note to look away from your screen regularly.
