Dots will look a bit fuzzy, and this is normal. Often, they look different from eye to eye. Look at the reticle with one eye, then the other. Red dot sight reticles will not appear defined and sharp like in a riflescope.

Most red dot sights are defined as Reflex Sights, which use an LED emitter, as opposed to holographic sights which use a laser diode. While the original sights were only offered in red, today green reticles are very common, and some other colors are available. A "closed" or "tube" design incorporates a lens behind the emitter and seals the space inside so that foreign elements or environmental conditions have less of an effect on or interference with the projected reticle. Red Dot Sights can be an "open" design, which is where there is a single lens located in front of the emitter. A red dot is ideal for hunting turkey or deer, and some people even use red dots for target games like trap, skeet, and sporting clays. The larger the dot, the quicker most people find they can find and shoot their target. Competitive speed shooters also use red dots on their handguns for the same reason. Much of our military uses red dot sights on their small arms because the hit percentage is drastically higher than with iron sights. A red dot sight can be used for precision shooting but is ideal for very close or very fast shooting. Red Dot Sights provide a cleaner sight picture than iron sights and allow the shooter to stay focused on the target rather than on the front sight. Therefore, they do not have a set distance of eye relief like a traditional riflescope. Most red dot sights are zero power, or one power. A red dot sight is an optic that uses a projected reticle, often a single dot only, as an aiming device.
