ONR's TechSolutions Providing SEALs With New Glasses That Change Lens Color On The Fly

By Geoff S. Fein, Office of Naval Research, Corporate Strategic Communications
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. 

John F. Williams / Navy The experimental Fast-Tint Protective Eyewear sunglasses currently are going through field tests. User evaluations and final results are due in April.

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.
TechSolutions accepts recommendations and suggestions from Navy and Marine Corps personnel working at the ground level on ways to improve mission effectiveness through the application of technology. It is solely focused on delivering needed technology and moving the sea services toward more effective and efficient use of personnel. TechSolutions uses rapid prototyping of technologies to meet specific requirements.

Smith Optics Elite On APEL

Authorized Protective Eyewear List (APEL) now includes the Smith Optics Elite Division.
Established in 1965, Smith is known for high performance snow and motocross goggles, as well as their lineup of sunglasses.  However, what we care about most is the new Outside the Wire (OTW) Ballistic goggle and Aegis eye shield, both of which are listed as exceeding government standards.  The OTW and Aegis have interchangeable pieces so those wearing prescriptions aren’t left out.
Smith says they are getting ready to launch a complete tactical line of sunglasses, we are looking forward to seeing how they look and hold up.

Γυαλιά και Μάσκες



ΠΡΟΣΟΧΗ στην επιλογή γυαλιών ή μάσκας για την προστασία των ματιών.
Τα γυαλιά και οι μάσκες που μπορούν να προστατεύουν αποτελεσματικά τα μάτια μας έχουν συγκεκριμμένες προδιαγραφές, οι οποίες πιστοποιούνται από ανεξάρτητα εργαστήρια. Αυτές πρέπει να αναζητούνται στην συσκευασία τους και είναι:

ASTM F 1776-01, ANSI 87.1 2003, MIL-V-43511C

Στις φωτογραφίες φαίνονται τα αποτελέσματα από βολές ΒΒ σε γυαλιά που ήταν ακατάλληλα.

ΠΡΟΣΟΧΗ : η επιλογή του μέσου προστασίας ΝΑ ΜΗΝ γίνεται με βάση την εταιρεία κατασκευής μόνο, αλλά και με βάση το ειδικευμένο μοντέλο.

Για παράδειγμα, η εταιρεία SCOTT κατασκευάζει μάσκες προστασίας για διάφορα σπορ. Η παρακάτω μάσκα είναι κατασκευασμένη για την χιονοδρομία και έχει προδιαγραφές που δεν καλύπτουν τις απαιτήσεις στο Airsoft. Η ίδια εταιρεία κατασκευάζει εξαιρετικής ποιότητας μάσκες για Paintball που είναι κατάλληλες και για Airsoft.



Δυστυχώς, ακόμα και τα ειδικευμένα προϊόντα γνωστών εταιρειών κάτω από περίεργες, ακραίες και άγνωστες συνθήκες αποτυγχάνουν.
Στην παρακάτω φωτογραφία γυαλιά OAKLEY ράγισαν μεν, προστάτευσαν δε από ΒΒ που βλήθηκε από πιστόλι στα 5 μέτρα.
