Summary : Normally, the cornea, the transparent front part of the eye, gets oxygen directly from the air. This happens through diffusion, where oxygen from the air dissolves in the tear film and then passes into the cornea. In this process, Blinking plays a crucial role, as It spreads the tear film evenly across the eye, ensuring a fresh supply of oxygen with every blink.
However, when we keep our eyes open for too long—such as while gaming, reading, or focusing intensely on a screen—our blink rate decreases dramatically. This disrupts the normal flow of oxygen, causing the tear film to evaporate more quickly and depriving the cornea of the oxygen it needs. As a result, the eyes become dry, irritated, and fatigued, often leading to blurred vision, redness, and discomfort.
If this continues for extended periods, the cornea may experience hypoxia, which can lead to serious complications such as retention of fluid in the cornea, corneal neovascularization (abnormal blood vessel growth), epithelial cell damage, corneal ulcers, and vision impairment.
