Today, my brother thought it would be hilarious to put vinegar in my contact solution. I took my contacts out hours ago and my eyes still burn. FML.

Cool the injury down with water or burn bandage for a few minutes. Increase the temperature gradually as required for longer periods of cooling. Contact a doctor is necessary.

This control method can regulate the burn-off process of contact bridge according to requirements so that the required flashing voltage is lowered and the flashing heating efficiency raised.
