Which type of safety glasses offers the least protection against chemical exposure?

  1. Open frame safety glasses

  2. Full-frame safety goggles

  3. Wrap-around safety glasses

  4. Sunglasses with UV protection

The correct answer is: Open frame safety glasses

Open frame safety glasses provide minimal protection against chemical exposure because they are designed primarily for impact resistance rather than a complete seal around the eyes. This type of eyewear has an open design that allows for air circulation but does not provide a barrier to splashes or flying debris, which are common risks in environments where chemicals are present. In contrast, full-frame safety goggles create a seal around the eyes, preventing any chemicals from entering, and wrap-around safety glasses offer a more comprehensive coverage that reduces the risk of exposure from various angles. Even sunglasses with UV protection, while not suitable for chemical exposure, do cover the eyes adequately to provide some level of shielding from certain hazards, unlike open frame safety glasses. Therefore, when evaluating protective eyewear specifically for use in environments where chemicals are a concern, open frame safety glasses are the least effective option.
