Which type of glass is worn over prescription glasses for additional protection?

Over-spectacle glasses are specifically designed to be worn over prescription glasses, providing an additional layer of protection without interfering with the vision correction that the prescription lenses offer. This type of eyewear is crucial in environments where hazards are present because it allows individuals who rely on corrective lenses to protect their eyes without the need to replace their prescription eyewear.

Welding goggles, while providing a strong protective barrier for the eyes, are primarily meant for use in welding operations and do not accommodate prescription glasses comfortably. Chemical goggles are designed to protect against chemical splashes and fumes but also do not provide the option to wear over prescription glasses securely. Safety glasses are designed to protect the eyes from impact and debris but may not fit over prescription eyewear without compromising fit or comfort. Thus, over-spectacle glasses stand out as the optimal solution for individuals needing both vision correction and eye protection simultaneously.
