Best Red Dot for Astigmatism

Red Dot with StarburstThe starburst, or blob as many people see when looking through a red dot, is nothing new to me. It’s something that I’ve always been bothered by ever since I started using red dots a few years back. I’ve always been good about keeping my eye prescription up-to-date, but glasses and contacts only make the problem a little better.

If you suspect that you may have astigmatism, seeing your eye doctor is the first step. Without my glasses, the starburst on my red dot is noticeably worse. I thought wearing glasses would be all that I could do. The dot would just never be clear for me. That is until I started my journey to find the best red dot for astigmatism.

Fast forward about a year… AfterRed Dot - No Starburst trying several different optic brands and MOA dot sizes, I finally landed on the right red dot for me. Now, I have options for both pistols and rifles that make it a much more enjoyable experience using red dots on my firearms. Is the dot perfectly clear and circular now? Almost. There’s still a very slight distortion to the circle, but it’s almost unnoticeable unless I’m really paying attention to it.

The brands

No-name $30 optics

These are generally the worst for me when it comes to the starburst or blob effect on the red dot. Don’t get me wrong, I’ve purchased my share of cheap red dots and some of them actually look ok. Holding zero is another story that I won’t get into. If you have astigmatism, it’s probably best that you stay away from red dots in this price range altogether.


Vortex makes some fantastic optics. I actually have a couple myself. I’ve used both the Viper and Venom on Glocks and I’ve used a couple other Vortex red dots on AR platform rifles. The dot looks decent to me, but not great. There’s a fair amount of starburst and it’s much more noticeable when the dot is on a brighter setting. If you have good eyesight, I would certainly recommend Vortex for their quality optics and customer service. However, if you have astigmatism, I would either look at their etched reticle options or consider one of our Top red dots.


Trijicon is well-known as one of the biggest players in the red dot industry. They are also one of the pricier options, for a good reason. Trijicon makes incredibly durable optics and sights. They are trusted by law enforcement and the military for that very reason. For me, unfortunately, I don’t see the dot as clearly as I had hoped. I know this is 100% due to my astigmatism and that someone with good eyesight would see a nice, crisp circle.


EOTech is certainly a popular choice when it comes to red dots for rifles. For those who have a little extra money to spend on a red dot, this is a trusted option. EOTech’s holographic sights have been used by the military throughout the years, so that says something for the quality and durability of these sights. For me, someone with astigmatism, they actually work pretty well. I think there’s something about the larger 68 MOA ring around a 1 MOA dot that just helps to keep things clear for me.


Holosun is another well-known red dot manufacturer. They have a huge selection of rifle and pistol optics available. One feature that Holosun offers on some of their red dot sights is the MRS (Multi-Reticle System), which gives you the EOTech-style ring around the dot option. For me, Holosun optics produce the clearest circle. There is almost no distortion to the dot, whatsoever. Even when I do away with the ring and just use the 2 MOA dot setting, it looks great.

Best Red Dot for Astigmatism [Pistol]

1. Holosun 507C X2

Holosun recently released the 507C X2, which introduced a couple of small upgrades to the older V1 model, including a side-loading battery tray. I’ve used both V1/V2 and X2 on several pistols and both look fantastic, to someone with astigmatism. I often utilize the MRS feature while at the range, switching back and forth between dot only, ring + dot, and ring only. If I’m shooting at closer distances, I typically use the ring + dot. If I’m shooting at a longer distance, I will use the dot only. No matter what setting I choose, I can say with certainty that this is the best pistol red dot for me.

  • 2. Holosun 407C X2

    The Holosun 407C is another great option for those with astigmatism. This red dot offers the same basic features, except for the Multi-Reticle System. You are limited to a 2 MOA dot only. The dot still looks very clear to me and I can see it with little to no distortion. I like having the MRS option, so this would be my 2nd choice. That being said, the price is a little more attractive on the 407C. So, if you’re on a limited budget, this would be a good option for you.

    1. Holosun 510C

    When it comes to the best red dot for astigmatism and choosing a good option for your rifle setup, I found the Holosun 510C to be at the top of the list. I love the MRS feature and often choose the 65 MOA ring + 2 MOA dot setting. Both the ring and dot are crisp and clear for me. This red dot is on the large size and mimics the EOTech-style holographic sight, but is a perfect fit for your AR platform rifles. When using the 510C with iron sights, you’ll get an absolute co-witness. If you’re looking for a lower 1/3, Holosun offers a riser to help bring you to the appropriate height.

    Check out our detailed review of the Holosun 510C.

  • Up to 50,000 hours of battery life
  • 2 MOA dot + 65 MOA ring

    The EOTech EXPS2 is one of the most popular models offered by the company. It’s durable, reliable and offers decent battery life. This holographic sight produces a 1 MOA red dot with a 68 MOA ring around it. Unlike the Holosun MRS models, however, you won’t be able to switch between reticles. You’ll get a lower 1/3 co-witness when used with an A2 front sight. As for how it looks to someone with astigmatism… I found it to be pretty darn crisp. I still think Holosun red dots look a little clearer, but I would put the EOTech in for consideration if you have less than perfect eyesight.

  • 1,000 continuous hour battery life
  • 1 MOA dot + 68 MOA ring
  • Extremely durable construction

  • Defective Red Dot or Astigmatism Test

    If you’re seeing a starburst, comma, blob, or a series of small dots, you might be wondering if you have a defective red dot. While it’s certainly possible, there is a simple test that you can try to see if your red dot is working properly.

    Turn the red dot on and, using your mobile phone, point the lens down the sight as you would with your eye. How does the dot look? Is it crisp or is it showing you what your eyes are seeing? If the dot looks good, there’s a possibility that you have astigmatism.

    If that’s the case, and you haven’t already, make an appointment with an eye doctor. They are often able to prescribe glasses or contacts that will help to correct it. Again, this is the first step in your hunt for the best red dot for astigmatism.


    While I found the sights reviewed in this article to be the best red dots for my astigmatism, I can say for sure that they’ll work as well for everybody. We all are unique and have different levels of astigmatism and other eye conditions.

    In addition to testing, I’ve also done a lot of research on my own and found similar responses to people with astigmatism. At the very least, I hope this article helps to get you started in the right direction.

    If you have astigmatism and have found something else that works better for you, I’d love to hear about it in the comments.
