Why Is My Red Dot Blurry? [Possible Reasons + How to Fix]

A blurred or distorted vision is a shooter’s worst enemy as it gets in the way of precisely aiming at your target.

We’ll tell you all the possible reasons we know of, plus ways to fix that blurry vision.

Why Is My Red Dot Sight Blurry? [4 Reasons Why]

There could be several reasons behind hazy red dot sights. But here are four common reasons that cause such issues.

1. Dirty Lens

You might not notice dirt or water soiling your scope when you go out in the open to hunt or spend time in the shooting range.

With this, your red dot reticle might appear blurry the next time you peep on it.

How you store your scopes and gears also matters in this situation. If you keep it in a damp area, your lens will also appear moist.

2. Astigmatism

Poor eyesight would get in the way of seeing properly through the red dot sight.

There are a few different ways to know if the distorted image you see is caused by poor sight or a defective red dot.

We’ll discuss more of this in the following sections.

3. Minutes of Angle (MOA)

Dot size based on the Minutes of Angle (MOA) is a SIGNIFICANT factor you should consider. There are chances where you’re using inappropriate MOA for your intended purpose.

Higher MOA or a bigger dot size is ideal for fast-moving targets at a close range. Smaller red dot sights, on the other hand, are best for long-distance shooting.

4. Reticle Brightness Adjustments

When you have astigmatism, you’re likely to see a starburst reticle if the brightness is too low. This happens especially when you don’t wear corrective lenses.

How to Fix a Blurry Red Dot Sight

Is your red dot sight blurry? Here are 4 quick fixes you can do to address that distorted sight:

1. Wipe your lens clean – It’s best to clean your scopes before and after shooting sessions. While in the middle of hunting, wipe your optic lens occasionally to remove smudges and dirt.
2. Wear corrective glasses – If you have conditions causing poor eyesight, the best way to address this issue is by wearing corrective glasses prescribed by an eye doctor.
3. Use the right MOA – It’s also important to use an MOA that fits your condition and intended use. The size of your reticle would greatly impact precision.
4. Adjust reticle and magnifier – Shooters with astigmatism should increase the reticle’s brightness for it to appear rounder and crisp. You should also adjust the magnifier scope through the eyepiece, similar to prism optics and long-range scopes.

What Is Astigmatism?

Astigmatism is an eye condition caused by an irregularly shaped eye’s lens (cornea).

The light passing through the eyes is bent, and only part of the object is focused, which can create irregularities in a person’s vision.

Many shooters with astigmatism see DISTORTED red dots or multiple dots simultaneously.

People with mild astigmatism barely notice vision issues because they have good eyesight. There’s only a problem when they peep through the reticle.

Distinguishing Red Dot Astigmatism From Defective Optic

Use these tips to distinguish if the blurry dot is just a problem with a faulty optic or caused by bad eyesight.

• Take a picture of the dot while covering the front lens.
• Check the dot’s actual shape through the back iron sights. Looking through the rear peep sight reduces the light your eyes take in.
• Rotate the optic while keeping its focus on a target. When the distorted image moves with the optic, it’s defective.

If your scope passed the initial checks, blurry red dot sights are caused by vision issues and not a defective optic.

Frequently Asked Questions

Let’s answer more questions before wrapping things up.

What Distance Do You Zero a Red Dot?

The best distance to zero in for handgun users is 15 to 25 yards.

Why Is My Front Lens Slanted?

This is to allow enough light to beam from the LED emitter to the inside surface for the shooter to see at any viewing angle.

Why Does My Red Dot Look Like a Star?

If you don’t see a round dot, you might have astigmatism.

Is a Green or Red Dot Better for Astigmatism?

A green dot is said to be more helpful than a red dot. Prismatic sights are also good for people with astigmatism.

What Does Parallax-Free Mean?

Red dot parallax-free means the reticle doesn’t move away from the target even if you change head position.

Is a Red Dot Sight Better than Reflex Sights and Iron Sights

You can get better accuracy with red dot sights than with iron sights.

Iron sight is also quite difficult to use with its three focal points: two rears and the front sight.

On the other hand, open sights and a reflex sight provide brighter reticles and wider fields of view for better eye relief.

Conclusion

A blurred dot can get in your way to precisely aim at a target.

You can try these tips to address such issues. But, it’s best to first identify the reasons behind the distorted dot to get accurate solutions.
