For those with prescription eyewear, ESS has the solution. After lenses have been corrected by an optometrist and fit into the CDI™ Rx Inserts, these low-profile, Rx integrations slide into the CDI™ like any other replacment lens.  One set contains two lens inserts.

• Optometrists can easily fit prescription lenses into the nylon-framed CDI™ Rx Insert with a range of corrections to +/- 6.
• These inserts slide into the CDI™ frame just as any other replacement lens for quick interchangeability.
