Reader strength and lens colour

These safety reader glasses combine a wraparound half-frame with a 3.0 diopter gray lens. The polycarbonate construction meets ANSI Z 87.1 -2003 and CAN/CSA Z 94.3 -07 impact standards while providing 0.999 UV protection. Scratch-resistant coating helps maintain optical clarity during extended use. Adjustable temples allow a secure fit for a variety of head shapes.

Indoor tasks requiring magnification

The fixed 3.0 diopter suits wearers who need consistent close-up correction for inspection, assembly or reading small print. Gray tint reduces glare in bright indoor or covered outdoor areas without distorting colour perception. Workers who need variable magnification, photochromic transition or foam-sealed dust protection should consider a different model.

3.0 diopter magnification

The single decisive specification is the 3.0 diopter reader power, which cannot be altered after purchase. Buyers must confirm this exact strength matches their prescription or task requirement before ordering.

Questions about this item

What frame material and size do the Pyramex SB1820R30 glasses use for fit?

The wraparound half-frame is made of nylon and polycarbonate in a universal size with adjustable black temples for a secure fit.

How do I adjust the temples on these safety readers, and what is the common mistake?

Slide each temple in or out until the frame sits level; the common mistake is leaving them uneven, which tilts the 3.0 diopter lenses.

When should I replace the lenses on the SB1820R30?

Replace them when the scratch-resistant coating shows visible wear or the gray polycarbonate lenses no longer meet ANSI Z87.1-2003 impact requirements.
