A first cavity (11) is provided inside the sight base (10); the sight frame (20) is arranged on the peripheral side of the sight base (10) close to an eye side, and a second cavity (21) and a through opening (22) communicating the second cavity (21) with the first cavity (11) are provided inside the sight frame (20); the light source member (30) is arranged at the end of the first cavity (11) close to an object side, and is used for emitting light towards the eye side; the collimating lens group (40) is arranged in the first cavity (11); the reflector (50) is arranged in the first cavity (11), and is disposed corresponding to the through opening (22); and the beam splitter prism (60) is arranged in the second cavity (21). The axial position of the light source member (30) relative to the sight base (10) is adjustable; or the collimating lens group (40) comprises a first lens (41), a second lens (42) and a third lens (43) which are sequentially arranged and all have refractive power, and the axial position of the second lens (42) relative to the sight base (10) is adjustable. The red dot sight can hide the bright spot of the light source to reduce the exposure risk of the shooter, and can also ensure that parallaxes are within an allowable range when aiming distances are different, thereby ensuring and improving the aiming precision.
