Red dot vs. Holographic Sights

Red dot sights use a simple LED to project a red (or green) dot onto a specially coated lens. The dot is reflected back to the shooter’s eye, creating the appearance of the aiming point. This system is known as a reflex sight.

Sighting in your reflex sight

Sighting in a reflex sight requires patience and precision. Here's a basic method:

Astigmatism and reflex sights

Astigmatism, a common eye condition affecting the shape of the cornea or lens, can significantly impact the clarity of vision when using firearms reflex sights. For individuals with astigmatism, the reticle or aiming point may appear blurry, distorted, or elongated, making it challenging to acquire and maintain proper sight alignment. This distortion can compromise accuracy and hinder target acquisition, especially in fast-paced shooting scenarios.
