How to choose goggles correctly?

Goggles mainly come in three types: dust-proof, impact-proof, chemical-proof, and radiation-proof. While the lenses of the first three types are all colorless glass, they actually have distinct characteristics due to their different protective properties.

Arc Radiation

People working in electric welding, gas welding, steelmaking, and glassblowing industries often need to wear goggles to protect against arc radiation. However, the lenses of arc radiation-proof glasses come in different shades, designed to meet different requirements. When choosing goggles, consider the intensity of the arc radiation during the work.

The stronger the arc radiation, the darker the lens; conversely, the lighter the arc radiation, the lighter the lens. This is because infrared radiation from strong arc radiation can penetrate the lenses and irritate and damage the eyes, leading to occupational cataracts over time. Conversely, wearing dark protective glasses for long periods of time when the arc radiation is weak can significantly impair vision.

Dust-proof Goggles

As the name suggests, dust-proof glasses are used to protect against dust. Generally, the requirements for these lenses are relatively low. Impact-resistant glasses have very high requirements for lenses; they must be impact-resistant. For example, lathe operators, sanders, and stonecutters should all wear impact-resistant glasses. If these workers wear standard dust glasses, flying iron sand and gravel will shatter the glasses, causing greater eye damage.

Chemical Splash

Chemical goggles must have lenses that are resistant to acids, alkalis, and corrosion.
