Red Dot Sights & Astigmatism

Tips for Resolving the Issue

Are you having issues with blurred dots when you look through a red dot sight? It may not be related to the sight. It may be astigmatism, and there are options.

Have you ever looked through a red dot sight and noticed that the image isn’t crisp and clean as you expected it to be? If what should be a dot instead looks like a comma or a star, or if you see several dots instead of a single one, you might need to learn about astigmatism and red dot sights. While the issue can be related to a shoddy sight, it can also be associated with a medical condition affecting the eyes.


Understanding What Astigmatism is All About

Understanding What Astigmatism is All About

Astigmatism is an eye condition that happens to be quite common. It means that the lens or cornea of your eye is shaped irregularly. When this condition is present, light cannot enter the eye to meet a focal point found at or behind your retina. Because eyes with astigmatism aren’t able to focus light rays on a single focal point, it distorts your vision. Regardless of how far away you are some an object, it may appear to be blurry or have another anomaly.

Many people have a mild case of astigmatism and have no idea about it. It’s rather common for a hunter to purchase a red dot sight and use it, only to think it’s defective when the actual issue is astigmatism. We’ll explain how to determine the differences between the two a little later in this article.

There are many options for treating astigmatism, such as getting glasses, contact lenses, or even having surgeries like LASIK. While this can offer an improvement to your overall vision, it can also end up being quite expensive. However, there’s never anything wrong with improving your vision and eye health.

Determining Whether Astigmatism or a Red Dot Sight is the Issue

Options for Using a Red Dot Sight When You Have Astigmatism

Red Dot Sights and Other Options for Those with Astigmatism

The most common type of red dot sights that cause issues for those with astigmatism is reflex style. There are also prismatic and holographic red dot sights, which have their pros and cons but also tend to be less problematic for anyone who has astigmatism. While what works for you is going to be unique compared to others, some of the options below might be good choices.

Holosun HS510C Open Reflex Circle Dot Sight

If you’re determined to stick with a red dot sight when you have astigmatism, the best choice is the Holosun HS510C Open Reflex  Circle Dot Sight. This 2 MOA dot scope offers nearly perfect clearness for most people without blurriness or distortion. Also, it provides three different reticle options, including:

  • Single circle
  • Single dot
  • Circle with a dot in the middle

For those who have astigmatism, this is an excellent feature. You can try the small red dot at 1 MOA or the larger red dot at 65 MOA to determine which offers a better hunting experience for you. It also happens to provide a titanium-alloy body for durability, a shock-resistant hood, and an unlimited field of view.

Other features of this red dot sight for astigmatism include the ability to be powered by solar power and batteries and an integrated QD mount that makes it simple to mount and remove.

Vortex Optics Spitfire 1x Prism Scope

Vortex Optics Spitfire 1x Prism Scope

Prism sights are another option for those who have astigmatism, and the Vortex Optics Spitfire 1x is a great example. This is because a lens and etched glass are used to create the reticle, which reduces distortion and can alleviate the issues associated with astigmatism. However, these can be bulky and heavy, so those who want a light scope may not be happy using it.

The reason we chose the Spitfire 1x is because it removes or nearly eliminates the starburst effect for most individuals, so all you have left is a sharp, bright reticle for your shooting. It also has a dual tactical ring with both red and green illumination as well as 12 different illumination settings so you can adjust it for your specific eye.

The reticle with this sight is excellent for both short and long-range shooting and makes a fantastic choice for someone who has astigmatism but prefers not to use corrective lenses. Some of the features include:

  • Lack of a blurry or starburst dot
  • A longer than average eye relief
  • Included rails
  • Clear etched reticle
  • Short to long-range abilities
  • Green and red illumination

Another perk with this model is that it comes with a lifetime warranty, so if something goes wrong, you can get it repaired, no matter when that occurs.

Sig Bravo3 Battle Sight

Sig Bravo3 Battle Sight

The final of our top recommendations for those with astigmatism is the Sig Bravo3 Battle Sight. It’s highly rated by hunters who have astigmatism with great features like identical magnification, crystal clear glass, and an adjustable diopter. It has a wide field of view compared to many red dot sights and will be easier to use for those with this vision issue.

It’s also a prism version, so it has all the same perks as the Spitfire 1x that we went over above. The quality of the glass on this sight is superb and offers a fantastic level of clarity that even expert hunters will appreciate. It provides an easy to use illuminated horseshoe dot reticle that might work better than a red dot scope will for those with astigmatism.


If you have a red dot sight that isn’t working the way it should be, consider that it may not always be the fault of the product. Even if astigmatism is the issue, there are solutions to the problem to ensure you can aim and shoot with the best of them. It might take some effort and time to find the right red dot sight (or alternative) when you have astigmatism, but there are plenty of options.

While most people wouldn’t say that astigmatism and red dot sights go together, some are going to offer a better experience than others. It’s up to you to decide whether this is the right option for you when compared to corrective vision procedures or using a prism sight instead. Now that you know your choices, you can start deciding the right path to take for yourself.
