SGE Eyeglass Frame for Gas Mask – for prescription lens users (can be fitted with your prescription)FITS ALL SGE GAS MASKS/RESPIRATORS -New Model: Optical Lens Support 2 (just released near end of 2018)NEW Version #2 – comes w/removeable arms=backup glasses Brand new / New In Box – Manufactured in 2020 **NEW Model #2** Highly Improved Model: Cooler design/look/enhanced functionality. The new improved version has removeable arms that are not used when using it inside an SGE gas mask / respirator. But if needed, the arms can be snapped onto the lens frame giving users another pair of prescription lenses they can use as a backup or emergency pair. (Thats purely an additional feature, since you could leave the arms off & just store your mask with the lens support in place; It connects securely inside the mask & can be removed if desired.) For individuals making bug-out-bags or other emergency kits, this additional option is extremely nice & although the new model is slightly more expensive, it helps to make better use of the $ spent equipping the lens support/spectacle frame with your prescription lenses. Just like the old (edition #1), these work with ALL models of SGE gas masks [SGE150, SGE400, SGE400/3, SGE1000 (old model), SGE INFINITY, SGE400/3BB, and all Mestel versions, sizes & masks equipped with hood, and/or drinking system, etc.] NOTE: This listing is for the spec frame / lens support insert (GAS MASK IS NOT INCLUDED !!!!!!) Take these frames to your regular eyeglass company to have your prescription installed.Can be left inside the mask or removed if needed.
