Why is it important to wear goggles or a face shield while applying pesticides?

Wearing goggles or a face shield while applying pesticides is crucial primarily to protect the eyes from pesticide exposure. Pesticides can contain harmful chemicals that may cause serious irritation, damage, or even blindness if they come into contact with the eyes. The application process can create situations where pesticides are aerosolized or splashed, so having appropriate eye protection is essential to safeguard against these potential dangers.

While there are other important safety considerations, such as compliance with safety regulations and preventing inhalation of chemicals, the specific focus on eye protection underscores the vulnerability of the eyes and the severity of possible health consequences from pesticide exposure. Additionally, enhancing visibility may not be a primary function of goggles or face shields; their main purpose in this context is indeed to provide a barrier against harmful substances entering the eyes during pesticide handling and application.
