When a patient is instructed to receive eye drops bid, it means they should administer the drops twice a day. "Bid" is an abbreviation derived from the Latin phrase "bis in die," which translates to "twice a day." Therefore, the correct understanding of this instruction is to perform a total of two applications each day. This dosing schedule is commonly used for medications that need to be delivered consistently throughout the day to maintain therapeutic levels in the eye.
