Product Description
The Pentax ZT500G is a prescription safety frame built for professionals who need reliable eye protection without sacrificing comfort or fit. Constructed from durable non-conductive plastic, this frame is engineered to meet the demands of high-risk work environments where electrical hazard protection is a priority. The wrap-around design delivers extended coverage and a secure fit, keeping your eyes shielded from flying debris, dust, and peripheral impact throughout a full workday.
Offered in a full-rim construction with a generous 58mm lens width, the ZT500G is sized for a large, comfortable fit that works across a wide range of face shapes. Its unisex design makes it a practical choice for safety managers outfitting mixed teams, while the lightweight plastic build ensures all-day wearability without pressure or fatigue.
What sets the Pentax ZT500G apart is its prescription-ready design. Unlike standard safety glasses that force workers to choose between vision correction and eye protection, the ZT500G accommodates your prescription directly in the frame — available in distance, progressive, reading, blue light, Transitions, polarized, and tinted lens options. Whether your team works under fluorescent lights, outdoors, or in variable lighting conditions, there is a lens configuration to match.
Backed by EyeWeb's 41-day free returns, 24/7 customer support, and vision insurance compatibility, the Pentax ZT500G is a straightforward, dependable choice for anyone who needs certified safety eyewear that actually works with their prescription.
FRAME MEASUREMENTS
To ensure your frames fit perfectly, you first have to determine which size frames are best for you. The best place to start is with the measurements on a pair you already own. You know those little numbers on the inside of its temple? That's what you're looking for. The frame measurements appear in the following order: lens width, bridge width, and temple length.
Frame Width
To find frame width, measure the front of the frame from screw to screw
Temple Length
Temple length is the measurement in millimeters of the ‘arms' of the frame. This measurement does not vary as much as the others, with 135mm, 140mm, 145mm, and 150mm being the most common options.
Lens Height and Width
Lens height is the distance from the top of a lens to the bottom. Lens Width is the distance from the left side of a lens to the right side.
