Shield Optical Clip

Enhance your adidas sport and sunglasses with the Shield Optical Clip, a precision optical insert designed for clear vision and perfect fit.

Due to the cambered angle of the Performance Insert™ a necessary decentration (see picture) or a special lens conversion from Silhouette International are required.

To maximize the visual performance of the Performance Insert™ following guidelines should be strictly observed:

• Sphere correction range should be +/- 4 diopters
  
• Cylinder correction range should be +/- 1 diopters
  

Use a precise modular PD to compensate for the frame facial wrap

• Plus lenses Make PD 1 mm narrower each side
  
• Minus lenses Make PD 1 mm wider each side
  

To maximize the sports performance of these frames and the Performance Insert™ adidas recommend polycarbonate lenses. The visual performance is improved because of the thinner lens centres and they also provide more protection.

Suitable for bifocal lenses / not recommended for progressive lenses.
