Until now, none of the service bureaus (Shapeways et al) have the proven capability to print a lens with this clarity and quality. This is one of the first posts I've seen that details how to do it. You might be able to find someone with a Formlabs printer on 3D Hubs, but they would have to follow this guide to achieve the result. Resin is not cheap either. Overall cost including man-hours of manual testing might cost over $300 if you really wanted it!
