Holographic sights work by providing a holographic representation of the viewing field onto holographic film allowing the reticle to remain centered and fully visible even in the event of obstructions or damage. As long as part of the viewing window is visible, the holographic sight remains effective. Opposed to reflected sights, holographic sights have unlimited eye relief and the reticle remains centered regardless of the viewing angle eliminating parallax error. This technology also eliminates blind spots allowing instant target identification and engagement. With EOTech sights, the shooter can acquire, identify, and engage with both eyes open maintaining peripheral vision and maximizing the shooters effectiveness in tactical scenarios. Holographic sights not only maximize effectiveness they’re also highly reliable.
