how to cut onions without crying

• Use a sharp knife and cut slowly. Using a sharp, thin blade and cutting slowly minimizes the force applied to the onion, which reduces the number of tear-inducing droplets released into the air.
• Wear protective goggles. Wearing airtight goggles, such as swimming or laboratory goggles, provides a physical barrier that prevents the volatile compounds from reaching your eyes.
• Improve ventilation. Increasing airflow in your workspace using a fan or a stove hood vent helps disperse the irritating vapors before they reach your eyes.
• Manage expectations for home remedies. Common home remedies like chilling onions, holding bread in your mouth, or lighting candles have mixed results and often lack consistent scientific support.
