Don’t worry if you haven’t known much or even anything about either red dot sights or reflex sights. The reason is simple: many people also have the question of “Reflex sights vs. red dot sights, which are better?"

So, let’s read this article to uncover the answer.

How To Differentiate Between Reflex Sights Vs. Red Dot Sights?

There is no difference.


We want to stress that the Red dot sight IS NOT a specific type of sight. Therefore, it is uncommon to make a comparison between reflex sights and red dot sights.

Red Dot Sights, Some More Details

Professionals and people with knowledge use the term “red dot sight(s)” to refer to any weapon optic that uses a red dot as an aiming point.

In some sights, aiming points may also be in other colors (for instance, green dots).

The red dot sights include three different categories. They are:

  • Prism sights
  • Reflex Sights
  • Holographic sights
Among the three types, Prism sights are often magnified, making them better at long distances.

Holographic sights are similar (but in higher quality) to a type of reflex sight called exposed reflex sight.

Prism sights and holographic sights both have appealing characteristics. However, they also have drawbacks: Prism sights have an eye relief, and Holographic sights are much more expensive.

What Do You Know About Reflex Sights?

Reflex Sights, what are they?

So, now you know clearly that the reflex sight is just one of three types of red dot sight, don’t you?

But, you should also know that people usually use the two terms (red dot sights and reflex sights) interchangeably.

Next, we should briefly discover something about reflex sights.

Types of Reflex Sights

There are two types of reflex sights: exposed reflex sight (use battery powered light beam) and tube-shaped reflex sight (use tritium).

In an exposed reflex sight, there is a lens that functions as a mirror. The aiming point is projected forward onto a glass. The lens reflects it and allows you to see the red dot.

But tube type is one kind of reflex sight, in which there are TWO different lenses, and the aiming point is projected forward from the rear glass to the forward one. The beam of the light is contained within the tube.

Many gun lovers consider the characteristic of having no eye relief is the most significant advantage of the reflex sights.

That way, you can position your head anywhere and keep all eyes open while using the weapon.

They can also easily re-acquire targets with this weapon.

One more plus of reflex sights lies in the fact that they are so affordable in comparison to prism sights and holographic sights.

Some holographic sights are almost ten times expensive than reflex sights (but the quality is not that higher).

Have you known the following?

People use reflex sights for many weapons, in home defense or tactical use, in all types of general shooting. For an average rifle user, a reflex sight seems to be the most suitable.
