Buying Guide

What makes it tough for astigmatism sufferers to pick a red dot sight? The reason is a “collimating minating mirror” is used to create the dot. In the case of normal eyes, the beams of light contain one focal point.

The situation is different in astigmatic eyes since the beams of light get refracted into multiple focal points. It results in a dot that’s blurry and distorted.

Holographic Weapon Sights

HWS from companies like EOtech also produce an illuminated reticle. A key difference is the light bounces off something called a “holographic grate” instead of into one dot.

HWS setups can seem to have less distortion than red dot sights (RDSs) since the holographic grate can function like a polarizing filler. That said, it’s important to note that HWS products aren’t 100% aberration-free for astigmatism patients.

Prismatic Optics

These optics function more like rifle scopes, binoculars, and other traditional optics by using etched glass and lenses to manufacture reticles. The majority of shooters diagnosed with astigmatism report less aberrations vs. RDS/HWS systems. This is due to the lack of mirrors and collimators.

There’s also a side perk. The reticle is etched in glass instead of an image being projected on it. So, if the sight’s electronics fail or the batteries die the reticles usually go back to black.

Tips for Shooters with Astigmatism

  • Use corrected/polarized sunglasses when doing daylight shooting.
  • Consider HWS/prismatic optics if you can’t find the right RDS unit.
  • Focus on your target instead of the red dot
  • Test out a red dot sight to find a distortion-free unit
  • When visiting your optometrist show/draw the reticle pattern you view when looking into an uncorrected sight.
