What is a key feature of effective eye protection when using pesticides?

Effective eye protection when using pesticides is critically important to prevent exposure to harmful chemicals. The primary feature that makes eye protection effective in this context is full coverage and resistance to chemicals. This means that the eyewear should fit snugly to the face to prevent any pesticide from splashing or entering the eyes from the sides, above, or below. Additionally, the lenses need to be made from materials that can withstand the corrosive nature of certain pesticides, ensuring that they do not break down or allow harmful substances to pass through.

While lightweight construction, fashionable design, and adjustable straps may enhance comfort or usability, they do not directly address the primary function of eye protection in a pesticide application context. The essential aspect is ensuring that the eyes are fully protected from potential chemical exposure, making full coverage and resistance to chemicals the key feature of effective eye protection.
