I know you like your civi specs but..... The current range of Ballistic Eyewear consists of the Lightweight Ballistic Protection (looks like wrap around sunglasses) and the medium weight ballistic protection (small goggles). Both are designed to stop shrapnel and debris kicked up during operations. For normal use the sunglasses give a reasonable amount of protection and when things look like they are getting nasty stick them in your pocket and slide the goggles down off your helmet. The protection of the goggles is higher ballistically but both give 100% protection against UV. Currently they are both provided by the US Company ESS (Ice 2.4 and Advancer respectively). More info on their site at http://www.esseyepro.com/index.html. Both are provided with 3 interchangeable lenses. Clear for normal and low light, tinted for bright sunlight and yellow for flat light (Dawn and dusk). The yellow lens may change to a 'coral' colour (reddish to you and we but we can't issue rose tinted specs can we!) This may improve the recognition of certain shades of green. The extras in the packs include stickers, straps, covers etc. All are designed to encourage people to wear them. Unless you are an expert in technical specifications then you will not be able to compare the claims of rival manufactures. Needless to say if you are wearing a knock of set from a local Afgan shop then take a final good look at a picture of the kids or girlfriend. In an incident in which the issued stuff would have saved your sight the shop bought stuff may or will shatter and blind you. Scars in the bar are good for bragging but blindness is not. Nuf said. Despite a simple system some people still manage to deploy without corrective lenses for the issued ballistic eyewear. This rest of this sticky sets out the procedure and explains what happens in real life. Corrective lenses. Simple...... Get the QM to order the unfortunately named 'Vice RX Kit. NSN 8465 99 318 7191. This contains the dummy lenses and the 2 clips which make the same set of corrective lenses fit into either one of the protective eyewear. Picture below.....Don't wait for them to arrive. Go to your Med Centre and get a form FMED 79. Ring up your local optician (check with the Med Centre who they have a contract with; here its spec savers.) Get your eye test done and then take the form back to the Med Centre. On the form you can tick Respirator lenses, glasses etc. The one you are worried about is goggles. The key measurement (apart from presumably the fact that you need magnification?) is the PD measurement (pupil distance) When the lenses come back fit them into RX inserts, freshly issued from the QMs, and fit them to either of the protective eyewear systems. Some Facts: The normal lens issued is fine for most people. Although there are not specific boxes for bi or Vari-focal lenses the FMED 79 has a box that can be filled out and the necessary sections and space to allow the optician to state the requirement for bi or varifocal lenses. I have checked with the manufacture of the lenses, its currently a specialist firm in West Sussex, and they do make them and have done so. However they also pointed out some why vari-focal's are not a good idea. Vari-focals gradually increase\decrease the magnification which stops the need for the traditional bi-focal line seen in those type of glasses. It also obviously stops sudden switch from the reading bit to the distance bit of the lens (its also classed as being more fashionable, but that wouldn't mean anything to a tough and battle hardened solder like you would it!!) The trouble is that vari-focals need to be aligned with the wearers eyes very accurately. So a slight movement in the way the eyewear is being worn will shift the magnified bit away from where its needed to where its not. The smart money is tells me that in an active environment vari-focals are definitely not recommended as any knock will make the wearers sight even worse than wearing no glasses at all. The corrective lenses are made from toughened plastic and conform to CR 39. Whats CR 39? Wiki says: 'CR-39 is transparent in visible spectrum and is almost completely opaque in the ultraviolet range. It has high abrasion resistance, in fact the highest abrasion/scratch resistance of any uncoated optical plastic. CR-39 is about half the weight of glass and index of refraction only slightly lower than that of crown glass, making it an advantageous material for eyeglasses and sunglasses lenses. A wide range of colors can be achieved by dyeing of the surface or the bulk of the material. CR-39 is also resistant to most of solvents and other chemicals, to gamma radiation, to aging, and to material fatigue. It can withstand the small hot sparks from welding. It can be used continuously in temperatures up to 100 Â°C and up to one hour in 130 Â°C' In short getting a set knocked up at the local opticians because you can't be arsed to put the paperwork in may get you a dangerous piece of plastic (or worse still expensive glass) sitting over your delicate eyes. The manufacture regularly turns the corrective lenses around in a single day if required. If its taking months then its your unit or the Med Centre so kick up a fuss. If your in theatre now and reading this get down to the Med Centre and get it sorted by post.
