Is your red dot sight blurry? Most likely it's caused by the LED emitter red dot starburst or using a red dot with astigmatism.

Here are 5 things you can try to see a much more crisp dot for better aiming.

Wear Corrected Lens

Most red dot sights on the market today have a clean dot under a digital camera. For the most part, correcting your vision is the best thing to do before anything else.

Shooters with different levels of astigmatism and bad eyesight will see smeared or blurry reticles due to the imperfection of eyeball curvature and it's different for every person.

We also recommend using prism sight where the glass etched reticle is much more clear for shooters with astigmatism.

Use A Bigger Dot

Please try a 6 MOA or bigger dot sight, so the bloom effect of the emitter red dot starburst is less under daylight use, and the dot is much rounder and crisp for shooters with astigmatism to see.

If the reticle brightness is turned up on a 1 MOA dot, shooters will generally see the starburst more than the rounded dot. You can still aim with it, unfortunately that's the what shooters have to deal with.

Since everyone's eyesight is different, a larger dot red dots that work with astigmatism are the best, while there are multiple brightness settings.

Reticle Brightness Adjustment Matters

See the difference below:

Please dial up the brightness while using a big dot reticle. The user with astigmatism without wearing glasses will see a crystal clear dot when the brightness is dialed up under the sun. Outdoor ambient light will wash the LED emitter starburst away, and leave the shooter a round dot to see.

Wipe Dirt Off The Lens

Cleaning off dirt, rain droplets, finger smear and oil residue off the lens will do the trick for the most part.

For shooters that train under rainy conditions or have occasional mud splashes all over their rifles, keeping the optic lens clean is something the shooters have to do constantly.

Use A Magnifier Scope

For a red dot with a magnifier scope setup, shooters must adjust the eyepiece (diopter) adjustment on the magnifier to focus the reticle.

The red dot and magnifier work independently, so the user must dial the eyepiece so the magnifier scope lens can focus on the reticle.

This works the same way for glass etched reticles on prism optics and long range scopes.
