Let’s talk tints...
The safety glasses on your face could be a number of different colors. Every lens design is made for a specific environment or situation. While there are some which are general and can be used in a variety of settings, there are others which should be used for distinct circumstances.
For general indoor applications which require impact protection. These don’t have any tint or color shade, and are pretty simple, standard safety glasses.
These lenses are made to be worn indoors or outdoors, but they have a slight gray tint which helps reduce glare from the sun or overhead lights. Sometimes these are also called “smoke” lenses. Fork lift drivers going in an out of warehouses or plants would wear these.
These are normally worn indoors, in potentially low-light applications. The Amber color helps enhance contrast.
These lenses are designed to block mid-infrared wavelengths and heat, while still allowing visible light to pass through. IR Filter safety glasses are commonly used around welding and cutting. They don’t replace a welding mask, but offer more protection for those in the general vicinity. 5.0 IR Filter shades are more heavily tinted than 3.0 IR Filter lenses.
Blue Mirror lenses are gray lenses with a blue mirror coating which reflects light. This cuts back the amount of light that actually passes through the lens and helps reduce glare and eye strain. Use these for outdoor work.
Much like the blue mirror, these are grey lenses with a silver mirror coating. They’re also to be used outdoors to help cut back light and reduce glare. Color preference between blue and silver is mostly a aesthetics preference.
These are solid blue glasses, without a reflective coating. Use these for indoor applications where there are yellow, or sodium vapor lights. The blue tint offers high contrast and helps cut out yellow light.
Red or Orange safety glasses use a gray lens with a reflective layer of silver and either red or orange coating. This helps reflect some light back, and also increases contrast and helps with color recognition. Use these outdoors where color recognition is important.

Introducing the NEW P53D Omni-Block from Rock Exotica. This is a very strong, ultra-efficient double sheave pulley. And it’s the only double pulley in Rock Exotica’s Omni-Block lineup with a prusik minding feature.
All Omni-Blocks have an integrated swivel, which reduces the overall height of your rigging system, and allows the pulley to automatically align itself. Plus, you can install and remove the rope without detaching the pulley from the anchor.
The P53D has a Minimum Breaking Strength of 40 kN. This is much stronger than all other Omni-Blocks. It also has a Working Load Limit of 10 kN, making it the overall strongest offering from Rock Exotica.
Rock Exotica CNC machines their Omni-Blocks from a single block of aluminum. This makes them lighter and stronger than the competition. Everything they do with their designs is done to make your work easier, and safer.
Check out the video below to see the Rock Exotica P53D Omni-Block in action.
