Red Dot vs. Holographic Sight

Here is a quick down and dirty on the difference between a Red Dot and a Holographic sight. 

Red Dot (Reflex): Uses an LED emitter bounced off a coated glass lens.

Pros: Unbeatable battery life (up to 50,000+ hours), lightweight, budget-friendly.

Cons: Can appear starburst-like if you have astigmatism; under a magnifier, the dot gets magnified along with the target.

Holographic Sight (e.g., EOTech): Uses a laser diode bouncing off mirrors to project a 3D hologram suspended in the glass.

Pros: The center 1 MOA dot stays precise under magnification (does not grow); faster target acquisition; works much better for shooters with astigmatism.

Cons: Chews through battery life (500–1,000 hours); heavier and more expensive.

So what should you go with?

Red Dot for standard home defense, budget builds, or set-and-forget battery life.

Holographic if you plan to run a magnifier or have astigmatism.
