Final answer:
To remove foreign material from an eye, the best method is by rinsing the eye with clean, lukewarm water, which helps to flush out the substance without additional irritation. The correct option is A.
Step-by-step explanation:
To remove a foreign material from an eye using irrigation, the correct method is rinsing the eye with water. This process involves gently pouring or squirting water into the eye to flush out the foreign substance without causing further irritation or injury.
It is important to use clean, lukewarm water and to tilt the head so that the affected eye is down, allowing the water to run away from the eye, carrying the foreign material with it. Eye drops, while helpful for lubrication and medication, might not provide the necessary force to remove particles.
Using a wet cloth is not recommended as it could press the material further into the eye. Blowing air could also cause more particles to enter the eye or could damage the eye with the pressure of the air flow.
