Radiation safety glasses work by attenuating harmful rays, significantly reducing the amount that reaches the eyes. Research indicates that leaded glasses can decrease radiation exposure to the eyes by a factor of 7.9 to 10. However, optimal protection requires the wearer to face the radiation source directly, as turning the head can diminish the protective effect.

Despite some practical challenges in achieving maximum effectiveness due to room setups and staff training, leaded glasses still offer substantial protection. The recommendation is clear: whenever lead aprons are required, radiation safety glasses should be worn as well. Glasses with a 0.75mm Pb lead equivalency, like those made from SCHOTT S6HT glass, provide robust protection. While regulations vary, with Europe mandating such glasses for interventional radiology, in the United States, the decision often lies with individual hospitals.

In addition to standard protection, radiation safety glasses can be enhanced with side shields to offer further protection from scatter radiation. This is particularly important in environments where radiation sources can come from multiple angles. Adjusting the fit and ensuring the glasses are worn correctly are crucial steps to maximize the protection provided.
