Product Description:

The Hudson SL-4 safety glasses offer accurate optical clarity, elegant style, and certified eye protection.  Engineered for professionals operating across active job sites, this model shields vision from airborne dust, dangerous splinters, and unexpected impacts.

Unlike standard plastic protective gear, the Hudson SL-4 features a premium metal frame in a sophisticated Slate finish. Its sleek rectangular design and inclusive, unisex fit give it a polished, professional appearance that is appropriate for both safety managers and workers on construction sites. 

The full-rim metal architecture ensures that workers wear their protective gear consistently over extended shifts by providing strong structural strength without adding heavy pressure points across the nose bridge or temples.

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.

Available Lenses

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

Distance lenses can be used in everyday life, whether you are shortsighted (wearing minus lenses) or longsighted (wearing plus lenses). They may also have the option of correcting astigmatism to give them clearer vision.

  • Tailored to one focus length
  • Wide field of view
  • Transparent lens

Progressive lenses are practical on a daily basis and provide clear vision to people who are either nearsighted (minus) or farsighted (plus). They transition seamlessly to the distance and can also accommodate astigmatism correction to enhance clarity.

  • Multiple focus zones
  • Smooth vision transition
  • Transparent lens

Reading lenses are ideal for everyday close-up work, and they are the best lenses that suit nearsighted (minus lens) and farsighted (plus lens). They may also contain astigmatism correction to provide clear, comfortable vision.

  • Tailored to near focus
  • Wide reading area
  • Transparent lens

Non-prescription lenses can be worn in day-to-day life to ensure eye protection and style, but not to correct vision. They do not correct shortsightedness or farsightedness, but provide comfort and sharpness to non-prescription users.

  • No vision correction
  • Wide field of view
  • Transparent lens

The blue light lenses are suitable to use every day when using a digital screen and whether you are near-sighted (minus lenses) or farsighted (plus lenses). They may contain astigmatism correction and may help in minimizing eye strain caused by exposure to blue light.

  • Tailored to one focus length
  • Blue light protection
  • Transparent lens

Transition lenses help in adjusting to the various light conditions, which is ideal whenever a person needs to use lenses in their daily life with either short-sighted (minus) or long-sighted (plus) eyesight. They may contain astigmatism lenses that provide clear vision both outside and inside.

  • Tailored to one focus length
  • Auto-darkening technology
  • Transparent lens indoors

Polarized mirror lenses minimize glare and improve clarity, which is perfect in a daily outdoor situation when a person has nearsighted (minus) or farsighted (plus) vision. Sharper vision can be corrected with astigmatism.

  • Tailored to one focus length
  • Glare reduction
  • Reflective mirror coating

Tinted lenses are ideal for everyday use, which helps reduce the brightness of nearsighted (minus) and farsighted (plus) individuals. They may have astigmatism correction to enhance clarity and comfort.

  • Tailored to one focus length
  • Decreases brightness and glare.
  • Available in various colors
