If we aren’t blinking enough on a regular basis, we reduce our nutrient supply to the eyes (per Healthline). You may also increase your risk for dry eyes. Eyes that aren’t adequately moist can cause painful or blurry vision. Additionally, the reduced supply of oxygen we experience when we blink less often can make us more susceptible to eye infections, since contaminants are also more likely to make their way into the eye. If we were to stop blinking altogether, the cutoff of oxygen could cause the cornea to swell.
Just like most habits, however, you can train yourself to blink more frequently. Experts at Advanced Vision Institute suggest implementing some 60-second power-blinking sessions throughout your day. During these sessions, try to blink 50 times within one minute while moving your gaze up, down, left, and right. You’ll want to make sure you’re getting in a full blink each time, not just a partial closure. Just be mindful not to squeeze your eyes tightly shut. Those who work on computers, in particular, may notice an improvement when it comes to eye strain and eye fatigue.
If you notice a change in how often you’re blinking along with symptoms such as redness, pain, light sensitivity, discharge, swelling, blurred vision, or issues with balance or muscle spasms, Healthline suggests consulting with your physician, as these can be signs of possible eye infection or an underlying health condition.
