Common FAQ

What Is Astigmatism?

Astigmatism is an imperfection in the curvature of the eye's cornea causing refracted light rays, which leads to blurry vision. Eye doctors call this "Refractive Error".

This may include:

  • Nearsightedness or myopia
  • Farsightedness or hyperopia

Bottom line - Human eyes aren't perfectly round, and an oval shaped eye will see reflections you might not normally see involving light. Astigmatic cornea distorts the light focal point in front or behind the retina.

eye shape astigmatism

Astigmatism exists within ~25 - 36% of the population have astigmatism according to National Health and Nutrition Examination Survey.

Did you know ? You could have a perfect 20/20 vision and still have some astigmatism

How Does Astigmatism Affect Reticle Clarity Through An Optic?

Here is what shooters with astigmatism see when looking through a red dot.

shooters with astigmatism see this

A reflex red dot sight is created with a collimating minating mirror. In a normal eye, those beams of light all have one focal point.  

However in an astigmatic eye, those beams of light are refracted into multiple multiple focal points. So the shooters with poor eye sight will see the blurry reticle that looks smeared, starburst and distorted.

This problem can be very annoying for some shooters when using a BDC reticle like the 68 MOA Eotech Reticle, a distorted reticle may hinder your ability to aim precisely.

A large size MOA dot, 6 MOA or more generally appears much rounder and with less starburst compared to a tiny 1 or 2 MOA dot

As mentioned above, get your eyes checked or renew prescription is important to fight astigmatism to get accurate aim.

How To Tell If If Your Optic Has Problem Or Are Your Eyes?

The easiest way to tell the difference is to take a picture of the reticle using a camera because it doesn't have astigmatism. If it looks round and clean on a camera, then the problem is with your eyes.

To test this, please assume:

  • No ambient light reflection in the background
  • No glaring sunlight
  • Clean lens & emitter
  • No oily lens surface
  • No smeared fingerprints on the lens or emitter
  • Reticle brightness isn't too high

Not all shooters have the same level of astigmatism. One optic reticle may be perfectly clear to one shooter, but bad for another. So it varies a lot.

Here are 7 tips to counter astigmatism when using an optic:

  • Correct eye sight
  • Clean the lens to avoid poor light refraction
  • Pick a bigger dot between 3 - 8 MOA sizes
  • Adjust diopter / Turn down the brightness
  • Zero the dot using the most center part if the overall shape looks distorted
  • Co-witness through a rear peep sight to sharpen the reticle by restricting the light rays entering your eye and eliminate reflections and some of the additional focal points.
  • Try polarized eye protection or polarized lenses.

We highly recommend buyers to check out optics in person at your local outdoor retail store.
