The Bouton Eva Bifocal Safety Glasses are the first women-specific safety eyewear for mature women in the workforce. Lady Eva Bifocal Safety Glasses feature a polycarbonate lens with built-in bifocals. Now you can read or see fine detail without having to remove your safety glasses or wear bulky safety glasses over the top of reading glasses. The Eva Bifocals are available in diopters ranging from 1.00 - 3.00 in 0.25 increments, so you're sure to get the correct reading power you need. Exceeds ANSI Z87.1-2015 High Impact Requirements.
