R-5A Eyeglass Frames - Black Military issued Prescription Frame. Standard issue eyewear for all branches of the U.S. Armed Forces, these durable plastic eyeglass frames are proudly manufactured by Rochester Optical. The R-5A is a stylish, modern alternative to traditional BCGs (Birth Control Glasses), the former “standard issue” frames, offering a more streamlined look while maintaining military-grade durability. These unisex rectangular frames feature spring hinges for added comfort and are designed with enough vertical depth to accommodate a wide range of prescription lenses, including single vision, bifocal, and digital progressive (no-line bifocal) lenses. You can order the R-5A with your custom prescription, making them an ideal choice for everyday wear, duty use, or as a reliable backup pair. Available in classic Black and Brown, the R-5A delivers a combination of style, comfort, and strength that meets the demands of service members, veterans, and anyone who prefers rugged, dependable eyewear. Sunclips and Temple Replacement Kits are available for this frame.
