Circuit FLEX - Matte Black

Due to their unique frame design, Circuit FLEX sunglasses are an ideal choice when making prescription-corrected absorptive filters for patients with higher refractive errors. The frames provide 8-base protection, but with the removable 6-base adapter in place, lenses can be made to accommodate stronger refractive errors while still benefiting from the close temple fit that an 8-base frame provides! 

As stand-alone sunglasses, the Circuit FLEX are a stylish choice for both men and women. They are available in two sizes, large and extra-large, and feature a flexible nylon frame. The rubberized nose and ear pieces provide for a comfortable fit as there are no sharp edges and the wrap around design offers full coverage protection.

The gray polycarbonate lenses that come in the frame block 100% of UVA and UVB light and have 15% light transmission. However, by using Eschenbach’s Custom Solution service, you can create prescription-corrected filters in almost any tint you want! Select from one of our popular off-the-shelf Solar Shield® filter tints of yellow, amber, orange, gray, or plum. Or choose one of our Ambles tints: 15 Light Amber, 50/15 Gradient Amber, 65 Dark Amber, 75P Darker Amber Polarized, and 85 Darkest Amber. We can also customize the Circuit FLEX lenses in any tint of your choice!
