The Pentax ZT500 Dust Dam brings together high-performance protection and all-day wear comfort for professionals working in demanding, dust-laden environments. Crafted with a sealed “dust dam” design, these safety glasses block airborne particles from entering around the lens-frame interface—perfect for laboratories, factories, construction sites or any high-hazard setting.

Key Features

  • Superior impact protection: Designed to meet ANSI Z87.1 standards for high-mass and high-velocity impacts. 
  • Dust-sealed construction: The Dust Dam sealing system provides enhanced environmental protection, helping guard against dust, debris, and other fine particulates. 
  • Wrap-style frame: Offers extended side-coverage and a secure fit around the face for better protection and stability. 
  • Non-conductive material: The frame is made of non-conductive plastic, making it safe for use in electrical or mixed-hazard environments.

  • Removable head strap: Adds secure retention when working in active or movement-intense applications.
  • Multiple lens options: Compatible with prescription lenses or standard clear protective lenses, accommodating users with vision correction needs.

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

Frame Width

To find frame width, measure the front of the frame from screw to screw

Temple Length

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 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.

We offer a variety of lenses to suit your lifestyle and vision needs. Explore our lens options below:
