Solid-Center blocks provide the extra support needed on AR coated lenses to prevent costly cracking and crazing. Available in 24mm & 18mm round, 17mm & 19mm half eyes, and 17mm x 30mm oval.

For optimal support, use the solid center blocks with the OptiSafe® Blocking Pads and OptiSafe® Anti-Slip Pads. This combination will prevent cracking, lens slippage, and twisting.
