5 Best Optics For Astigmatism

Does your reticle look blurry?

There is a chance you have astigmatism, and here are the 4 best sights for astigmatism with nice and crisp reticles to help fix the blurriness and aim with clarity and consistency.

They are generally prism scopes or scopes with glass etched reticles.

In this article, you will also learn why astigmatism exists and how to diagnose if the reticle is blurry or is your eyes bad.

Let's check it out.


4 Best Sights For Shooters With Astigmatism

Note: Every red dot or holographic sights will have slight lens distortions

Works For Cross Eye Dominance - Tilt the rifle to the dominance eye while maintain good cheek weld position using a tall mount.

Up to 700 Yards - Perfect for limited division 3-Gun competitors or range-goers who wish to engage targets from point blank to extended range up to 700 yards.

Shockproof -  Rugged construction withstands recoil and impact.

Features:

  • Magnification: 1X
  • Objective Lens: 25mm
  • Eye Relief: Unlimited
  • Reticle Type: 2 MOA + 65 MOA ring
  • Turret : 0.5 MOA / Click
  • Length: 3.3 inches
  • Weight: 4.94 oz

holosun 510c on sig mpx

Why buy the HS510C - The 510C is by far the best large POV red dot great for people with astigmatism at a hard to beat the price point.

Multiple Reticle Options - Cycle through 4 different reticles from a single dot to a 65 MOA ring reticle.

Fast Target Acquisition - Large CQB 65 MOA reticle circle for range estimation, perfect for accurate close-range shooting with a rapid holdover reference point

Near Infinite Battery Life - Solar failsafe technology extends the battery life longer to keep you in the fight longer without ever changing the battery

Features:

  • Magnification: 1X
  • Objective Lens: 35mm
  • Eye Relief: 2.39"
  • Reticle Type: TA11 BDC
  • Turret : 0.33 MOA / Click

shield rmsc reflex red dot sight

Why use Shield RMSc – The RMSc shares the same mounting footprint as the original RMS red dot, and it has the clearest lens and dot as far as for shooters with astigmatism. They gonna love it!

Durable polymer glass - Withstands up to 10X greater shock impact than glass optics plus minimal lens reflection for shooters with stigmatism

Perfect for single stack pistols - Fits flush on the Hellcat OSP slide. Looks great, feels great and built tough.

Super lightweight for CCW - Carry it any where you go without feeling like there is weight on you. 

USMC shooting HK M27 with ACOG 3.5X

Why Use Trijicon ACOG - The Trijicon ACOG reticle is clear as day on 3.5X for shooters with astigmatism because the a Prism sights etched the reticle on the glass instead of reflecting it causing light refraction , which means better clarity, eye boxes, good eye relief, and wide field of view.

Aim Both Eyes Open - Trijicon's Bindon Aiming Concept allows shooters to aim with both eyes open for improved situational awareness.

Improved Eye Relief - Get better cheek position and flexible eye box behind the scope without scope shadow

Various Reticle Options - We recommend the ACSS reticle for fast ranging and target acquisition.

Works In Low Light - Hit targets during dusk or dawn. Fiber optics on top of the ACOG illuminates the reticle even in low light conditions.

Features:

  • Magnification: 3.5X
  • Objective Lens: 35mm
  • Eye Relief: 2.39"
  • Reticle Type: TA11 BDC
  • Turret : 0.33 MOA / Click
  • Length: 8 inches
  • Weight: 14 oz

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.

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 without knowing until you get behind a red dot sight.

To learn more please reference WebMD

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.

Check out our scope guide for shooters with astigmatism 

Is It A Big Deal?

Having astigmatism can be very annoying for some shooters because they can't see a clean reticle but not for others.

For fast point and shoot applications, having a slightly distorted reticle isn't a big deal if it's intended for rapid combat effective hit.

However, for precision shots, a distorted reticle may hinder your ability to aim precisely.

If the reticle is too distorted, then it's better to visit your eye doctor.

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

Sometimes it's hard to tell whether the blurry reticle is due to your vision or is with the optic itself.

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

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.

Tip: Keep your optic lens clean!

Factors That Affect Reticle Clarity

Here are few factors that can make the reticle look fuzzy.

  • Anti reflection coating
  • Dot size
  • Dot brightness
  • Light transmission
  • Glass tint
  • Open vs closed emitter

7 Tips To Fix A Blurry Reticle

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.
