Short answer: Safety glasses differ in lens (plano or prescription), in side cover (side shields or wraparound) and in the standard they are tested to. Choose them for the hazard of the job, then check which standard your site or customer requires.

Plano safety glasses have lenses with no power. Prescription safety glasses carry the wearer’s own power. Some frames, like ours, take either, so one frame can serve a whole team.
Side shields are small panels at the temples, and wraparound styles curve around the eye. Both reduce what can reach the eye from the side, such as dust and small fragments.
Always choose eye protection to match the risk assessment of the job. Welding, chemical splash and heavy impact need specific protection that ordinary safety spectacles do not give.
Three are common: EN 166 (the European standard for personal eye protection), ANSI/ISEA Z87.1 (the United States standard) and IS 5983 (the Indian standard for eye protectors). Which one applies depends on your site, your country and your customer, so ask before you order.
