I have recently had a promotional email from Brownells promoting a red dot optic that is good for those with astigmatism. Some will recall I have suffered with red dots bursting in scopes. It sounds like a positive improvement. Once aginst the American name of the company doesn't really inspire but the design of the optic has to be credited.
From the advert;
ETCHED RETICLE
The CDC notes around one in three individuals face astigmatism, affecting red dot use. The Raider offers a superior option as its reticle isn't projected onto glass, reducing starburst effects. Illuminated within the optic, it prevents washout by weapon lights, unlike red dots. When activated, the reticle remains visible as a black silhouette, ensuring consistent visibility.
