They are used on activities like working in a chemical laboratory, woodworking and working with power tools like drills or chain saws. They are also used by pilots of open cockpit planes and in snow sports. These glasses are essential for people dealing with high intensity lasers. Swimmers in oceans or swimming pools using chlorinated water have to wear these glasses for protection.

The designs of these glasses depend on their use. For glasses used in cold weather there are two layers of lens to prevent the inside of the lens to become foggy due to the condensation of water vapor, as in a single lens. In the two lens combination the inside lens being close to the body is warmer and prevents water vapor to condense. If water vapor gets in between the lenses the condensate would be almost impossible to be removed. The dual layer lenses must be air tight and so need precision engineering to fabricate.

Eye protection safety glasses used in swimming must be water tight to prevent saline or chlorinated water to irritate the eyes. These allow swimmers to see clearly whole underwater. However, these are usable only up to a few feet below water. Beyond this water pressure press the glasses too tight against the face.

Glasses used for power tools operation have to be made from unbreakable material like plastic including CR 39 and polycarbonate. These goggles need to have some ventilation to prevent sweat from forming inside the safety goggles and blurring vision.

These glasses are indispensible for people handling lasers at high levels. Exposure to laser beams may cause harm to the eyes which must be adequately protected. While performing laser surgeries or laser skin resurfacing the surgeons must wear these glasses to protect their eyes from flashback.

For manufacture of laser safety glasses the manufacturers have to attain a high level of craftsmanship to conform to ANSIZ136 series of standards. Only products conforming to these standards are permitted for use in medical field involving use of lasers. For use in educational field, the glasses should have the ANSI stamp on them. If used outdoor the goggles should have ANSIZ136.6 mark.
