How much pesticide that contacts the eyes is actually absorbed?

The correct choice indicates that very little pesticide that comes into contact with the eyes is actually absorbed. This option reflects the physiological characteristics of the eyes and the barriers that exist to prevent substances from entering the systemic circulation. The eye has several protective mechanisms, such as the tear film and the epithelial barrier, which limit the absorption of foreign substances.

While some absorption can occur, the surface area of the eyes is relatively small compared to the skin, and the unique composition of the eye tissues provides a degree of resistance to the absorption of chemicals. Therefore, even with contact, the amount that enters systemic circulation is minimal, highlighting the importance of using proper protective measures to avoid exposure altogether.

This understanding is crucial for safe pesticide handling practices, as it emphasizes the necessity of using goggles or faceshields to protect the eyes from direct contact, even if the absorption risk appears low.
