The three packages are designed around these particular factors and include specific lenses to give the sportsmen the maximum effects for his/her enjoyment. They can even be adapted to have prescriptions for those sports enhusiasts who need corrective vision lenses. This unique rimless prescription system known as intraSPX™ Prescription Insert System can be interchanged between any of the polycarbonate lenses and used accordingly against prevailing weather conditions or facility backgrounds. It is the thinnest, lightest sport optical insert system in existence in single vision or bi-focal format, and can be supplied in either hardcoated plastic or hardcoated polycarbonate material.
Each polycarbonate lens meets or exceeds the ANSI Z80.1 requirements for impact resistances. They are coated with a scratch resistant material and also blocks 100% of the harmful UV light rays. Each are carefully crafted utilizing a 6 base lens curvature, which closely matches the actual curvature of the eye. This important step eliminates virtually all distortion properties across the normal viewing range, and makes this system the best all-around package in today's marketplace.
