Fitover Lead Eyewear - Model 42The new 42 lead Fitover eyewear, like the 89 and 90 leaded Fitovers, is made to wear over prescription eyewear. The 42 Fitover features a smaller vertical dimension than other fitover styles as well as 0.5mm Pb lead sheeting for side shields, thus decreasing the weight by approx. 20%. The fitovers are an excellent choice for those requiring splash protection.
