What can decreased blinking during prolonged digital device use lead to?

Decreased blinking during prolonged use of digital devices can lead to discomfort primarily because blinking plays a crucial role in maintaining eye health and comfort. Blinking helps to spread tears across the surface of the eyes, keeping them moist and clearing away small debris. When blinking is reduced, which often happens when people focus intently on screens, it can result in symptoms such as dry eyes, irritation, and overall discomfort.

The other options, while they may seem plausible, do not hold true in the context of decreased blinking. Enhanced vision is unlikely because lack of proper lubrication can lead to blurred vision instead of improving it. Improved focus does not correlate with reduced blinking, as discomfort can actually hinder concentration and productivity. The concept of stronger eye muscles is also misleading since muscle strength does not directly increase from blinking less; rather, eye fatigue may result from the strain of fixed focus without adequate tear distribution.
