A laser dot sight device includes a red dot sight that is mountable to a firearm to facilitate a shooter to aim the firearm with the red dot sight. The red dot sight includes an emitter housing, a lens housing extending upwardly from the emitter housing and a lens that is integrated into the lens housing. The lens housing is comprised of a translucent material thereby facilitating light to pass through the lens housing. In this way the lens housing can facilitate the shooter to have unimpeded peripheral vision while looking through the red dot sight.
