Pilla or Randolph Engineering would be my top 2.

You see through the optical plane where the dot is projected, the target stays in focus. Usually regular distance focus prescription lenses work just fine. Optical sights and red dot optics don't require corrective lenses except for astigmatism to eliminate "flare"!
From Dr. Wong

Normally, the best lens for the red-dot scope viewing will be the best distance prescription. Demonstrate this lens while the patient looks at the red dot while holding out the scope. Because the red dot in the scope is not focused at "optical infinity" (it is closer), try a +0.12 or a +0.25 diopter lens over the best distance prescription to see if the dot becomes even clearer. If possible, judgment would be best if the patient can view at a distance greater than the standard 20 feet and with outdoor lighting. If the dot is distorted, use the phoropter once again to verify cylindrical power and axis as the patient holds the pistol (or scope only) in front of the phoropter. Final results should be demonstrated with trial lenses. If the red dot never becomes clear and round after all lens possibilities have been demonstrated, then a careful determination of ocular health involvement needs to be assessed.
