Eye protection for handling pesticides must prevent chemical splashes from reaching the eyes and resist exposure to the active ingredients. Regular prescription eyeglasses are not designed to seal around the eyes or to protect against chemical splashes; they have gaps at the edges and are not tested or rated for chemical exposure. Because of that, they do not provide adequate eye protection in pesticide work. The right choice is chemical splash goggles or a face shield (or safety glasses with side shields that are rated for chemical splash) that fits properly and meets protective standards. If needed, you can wear prescription glasses underneath appropriately rated goggles, but relying on regular glasses alone leaves eyes at risk.
