20120008192 | IR FILTERS WITH HIGH VLT AND NEUTRAL COLOR - An optical filter composite is provided having effective filtering of infrared emissions, such as solar or laser emissions, while providing very high visible light transmission, preserving the ability to differentiate and recognize colors and providing a pleasing overall color as compared to the prior art. The present invention provides for filters that are formed by lamination, infusion and/or coating processes using filtering assemblies having a neutral color with high visible light transmission while also producing high levels of filtration in the infrared and near infrared range to provide effective protection against harmful emissions in these ranges while also producing a filter that has a color that is more pleasing and desirable to the wearer. | 01-12-2012 |
20110046582 | RETROFIT KIT AND METHOD OF RETROFITTING A PLUMBED EMERGENCY EYEWASH STATION - A retrofit kit for an emergency eyewash station and method of retrofitting a plumbed emergency eyewash station is disclosed. The kit includes a sterile eyewash fluid source. A pump assembly having an input port and an output port is also included. The input port is configured to connect to a dispensing structure of a plumbed eyewash station and the output port is configured to connect to the sterile eyewash fluid source. A drive assembly is configured to drive the pump assembly to draw sterile eyewash fluid from the sterile eyewash fluid source and discharge it through the dispensing structure of the plumbed eyewash station. The eyewash fluid discharged from the dispensing structure is configured to drain through a discharge of the plumbed eyewash station and away from the plumbed eyewash station. | 02-24-2011 |
20100231850 | SAFETY EYEWEAR - The present invention relates generally to safety eyewear and more particularly to a safety eyewear having a horizontal ledge defined within a lens of the safety eyewear for attaching the nose piece structure. The safety eyewear includes a frame and a lens. The nose piece structure configured for attachment to a central portion of the lens. The nose piece structure having a channel defining horizontal ledge indents for mating engagement with horizontal ledge protrusions defined within the central portion of the lens. The central portion of the lens defining horizontal ledge protrusions for inserting within the ledge indents of the nose piece structure when the nose piece structure and the lens are attached together. In another embodiment, the channel of the nose piece structure defines horizontal ledge protrusions for mating engagement with horizontal ledge indents defined within the central portion of the lens. | 09-16-2010 |
20100225879 | SAFETY EYEWEAR - The present invention relates to safety eyewear having a nose piece structure with multiple axes of adjustment. The nose piece structure includes a nose support and a nose pad. The nose support having a substantial inverse V or U shape configured for attachment to a portion of eyewear. The nose pad has a metal core overmolded with a soft deformable material which can be adjusted along an axis. An insert portion of the metal core extends outside of the material of the nose pad along a horizontal axis for insertion within the receiving portion of the nose support. The nose pad defines multiple non-uniform fins for comfort and adjustment along an axis. The receiving portion and the insert portion attached together to allow adjustment of the nose pad along an axis. | 09-09-2010 |
20100220283 | SAFETY EYEWEAR - The present invention relates generally to safety eyewear and more particularly to a safety eyewear including a wicking device attached to the safety eyewear to remove or absorb perspiration. The safety eyewear of the present invention includes the wicking device attached to a frame of the safety eyewear to remove or absorb perspiration. In one embodiment, the wicking device includes a brow-bar, sub-frame, and wicking material. The sub-frame removably or permanently attached to the frame of the safety eyewear using a variety of means for attachment to the eyewear frame. The brow bar removably or permanently attached using variety of means for attachment to the sub-frame. The wicking material removably or permanently attached using a variety of means for attachment to the brow bar. | 09-02-2010 |
20100220281 | SAFETY EYEWEAR - The present invention relates generally to safety eyewear and more particularly to a safety eyewear that includes a coloration or tinting of an outer peripheral edge of the lens for indicating a performance characteristic of the safety eyewear or the lens and selected absorption of visible wavelengths of light. In one embodiment, the eyewear includes a VLT rated lens having a light visible tint or slight mist tint to provide ornamental coloration of the outer peripheral lens edge. The lens has a roughened or textured cut along an outer peripheral edge of the lens to diffract light. The outer peripheral lens edge is color coded according to a performance characteristic of the lens or the eyewear. In operation, the ornamental color of the outer peripheral edge of the lens is activated upon the diffraction of light along the roughed or texture outer peripheral edge of the lens while still meeting industry VLT requirements for a substantially clear lens. | 09-02-2010 |
20100110370 | LASER PROTECTIVE EYEWEAR HAVING IMPROVED GLARE PROTECTION - A molded optical filter is provided having effective filtering of energy emissions at an optical density (OD) of greater than 4 in three energy emission bands corresponding to the wavelengths of laser emissions while preserving the wearer's ability to differentiate and recognize colors and having a pleasing overall color. The selective optical filter is a moldable polymer filter that has three dyes therein to produce sharp notch filtering ranges at about 530 nm, 700 nm and 1060 nm and a fourth color balance dye therein to adjust the overall color of the filter making it more pleasing and desirable to the wearer. | 05-06-2010 |
20090268157 | LASER PROTECTIVE EYEWEAR HAVING IMPROVED GLARE PROTECTION - A molded optical filter is provided having effective filtering of energy emissions at an optical density (OD) of greater than 4 in three energy emission bands corresponding to the wavelengths of laser emissions while preserving the wearer's ability to differentiate and recognize colors and having a pleasing overall color.
