ARLINGTON, Va. - The Office of Naval Research's  (ONR) TechSolutions department is set to deliver to Navy Special  Warfare Command personnel later this year new protective eyewear that  will eliminate the need for war-fighters to stop to change out colored  lenses to accommodate differences in light levels.
The Fast-Tint Protective Eyewear (FTPE) changes color quicker  than transitional lenses commonly found at an optometrist's office.  "Transition time is less than 0.5 seconds," said Stephanie Everett,  ONR's TechSolutions program manager. 
"Currently, war-fighters are using a set of interchangeable lenses  that require them to stop and manually switch lenses to adjust the  goggles to a particular light environment," Everett said. "But they  can't take the time to stop and remove and replace the lenses." 
Instead, they often simply remove their sunglasses when moving  inside, leaving their eyes unprotected. The FTPE was designed to enable  them to maintain ballistic protection under all lighting conditions,  without interrupting their operational tempo.
Liquid crystal solutions within the lenses contain customized  dyes that transition to amber, blue, dark gray or clear when an electric  charge is applied. Lenses can change color automatically as wearers  move in and out of varying environments, or lens colors can be altered  manually by pushing a small button on the side of the glasses.  Additionally, the lenses meet the American National Standards  Institute's ballistic impact safety requirements.
The request for new eyewear came to TechSolutions from war-fighters in July 2009, and the project is almost complete. The  initial delivery was for 30 pairs of the new eyewear, which have already  gone out for evaluation with war-fighters who will use them in training.  "They will provide structured feedback on the glasses," said ONR's  Command Master Chief Petty Officer Charles Ziervogel, who oversees the  TechSolutions department.
After this evaluation, Special Operations Command (SOCOM) is  expected to take delivery of the FTPE glasses. "SOCOM is buying 100  units based on the initial assessment and seeing the results from the  current evaluation," Ziervogel said.
Last August, an earlier prototype was assessed, which led to  design changes, which are incorporated in the current eyewear. "The user  feedback made this prototype even better," Everett said.

Results from this round of assessments are expected in April, and  the feedback will be forwarded to Ohio-based AlphaMicron. The company,  along with Naval Surface Warfare Center Crane, Ind., was selected to  develop FTPE.
"We expect additional minor design changes based on the results of the current assessment," Everett said. AlphaMicron will incorporate any changes into what will be close to a final product.
