5 Best Red Dots for Astigmatism – Reviews and Buying Guide


Astigmatism is a common vision problem and can be defined as a refractive error where the eye cannot focus light evenly on the retina. Having astigmatism results in blurred vision when trying to view or shoot at any distance and a continually distorted sight picture during hours of observation. Let us take a look at a few red dots that deliver a reliable optical performance for shooters with Astigmatism. 

Unfortunately, I have astigmatism and cross eye dominance which makes it quite difficult for me to shoot with both eyes open. Majority of the time, my vision is blurred and I cannot spot my target or prepare for an accurate shot. It gets even worse at night and during the day when it is too bright outside. Before actually realizing that my eyes were the problem, I would often complain about the quality of the red dot sight that I had just purchased at that particular moment and I would even go ahead and purchase a new one hoping that I would be able to at least access some kind of optical clarity across the entire visible spectrum. With time, I came to realize that there are a bunch of red dot sights that have been optimized to meet the optical needs of individuals with astigmatism. In this article, we have picked 5 of the best red dot sights for Astigmatism.

How to overcome Astigmatism when using red dot sights?

The reason as to why your vision is affected when you are using red dot sights and not with other optics is because red dots work by reflecting a red dot image from an LED back to your eye. Once there is a reflection, astigmatism becomes a challenge. So, how can you deal with astigmatism when using red dot sights?

Reduce the brightness levels on your red dot to the lowest setting

Avoid maxing up on the brightness of your reticle. When the illumination of your red dot sight is on the highest brightness settings in the wrong lighting conditions, the bright red dot can appear to have a halo, bleed or starburst. To avoid this, you would need to turn down the illumination so that you can acquire a round, crisp dot.

Choosing Green Illumination over the Red One

We can deduce that dot sights with green illumination are preferred by most users with Astigmatism because there is less image distortion. For this reason, you should choose red dot sights with multiple reticles such as the ones that we have mentioned in the article above. This way you will be able to counter the blurry effect caused by astigmatism.

Try using polarized glasses

Polarized glasses help correct astigmatism as they help straighten out any scattered light before it gets to your eye. Once the light is concentrated on a single focal point, the effects of astigmatism is then reduced.

Get treatment

The best solution would be to see a doctor so that you can understand whether you would need to undergo surgery or find alternative solutions that could help you overcome astigmatism.


Astigmatism may seem a barrier to an immersive optical experience during your shooting escapades. However, this does not means that you won’t be able to enjoy hunting or sports shooting. After testing your red dot optic and confirming that indeed the issue lies in your vision, all you would need to do is ensure to seek alternatives to red dot sights and make the most of them.
