Readers ask: What Are Safety Glasses Made Of?

Most safety glasses are made from polycarbonate, a lightweight but strong material. Although the material is different, safety glasses can have prescription lenses or non-prescription lenses, like regular glasses.

What are safety goggles made of?

Safety eyewear generally comes with shatter-resistant polycarbonate lenses. This lens material is thin and lightweight, even with stronger prescriptions. Polycarbonate can scratch easily. Select a scratch-resistant lens coating and store glasses in a cushioned case when not in use.

Are all safety glasses polycarbonate?

Since then, polycarbonate lenses have become the standard for safety glasses, sports goggles, children’s eye-wear and a variety of other uses.

Are safety glasses made of glass?

Yes, safety glasses can have glass lenses. The most popular lens material for safety eyewear is polycarbonate. Trivex lenses are growing in popularity too. These lens types are more popular than glass lenses for many reasons, but mainly it’s because of their high impact resistant, lightweight, and UV light resistance.

What makes safety glasses safe?

Safety glasses are designed to protect the eyes from workplace hazards. They are made of strong polycarbonate material, reducing the risk that flying objects, dust and other hazards may harm the eyes. Safety glasses are the most common and effective personal protection equipment for American workers.

Which is better polycarbonate or plastic lenses?

Thinner and lighter than plastic, polycarbonate (impact-resistant) lenses are shatter-proof and provide 100% UV protection, making them the optimal choice for kids and active adults. They’re also ideal for strong prescriptions since they do not add thickness when correcting vision, minimizing any distortion.

Do polycarbonate lenses meet ANSI Z87?

Ultraviolet protection has been incorporated into the polycarbonate lens material when the lenses were manufactured. They meet ANSI Z87. 1- 2010 requirements and can block 99.99% of harmful UV sun rays.

Are safety glasses shatterproof?

Safety eyewear frames must be more durable and sturdy than frames for regular eyewear. Safety frames are made of different shatter-resistant materials depending on the application and sometimes include side shields.

Are safety goggles made of plastic?

Polycarbonate is the most common material used for lenses in safety glasses. Glass and plastic aren’t used for lenses in safety glasses because they’re likely to shatter under high impact. Lenses are tested differently than frames. For a basic impact test, lenses are tested separately from the frame.

What polymer is used for safety glasses?

The most popular lens material for safety eyewear is polycarbonate. This material has less than half the weight of glass, so the eyewear is more comfortable. Polycarbonate lenses are also more impact-resistant than glass lenses. Keep in mind that polycarbonate is a much softer lens material than glass.
