An adjustable object lens device includes an outer barrel, a rotary component coupled movably to the outer barrel, an object lens unit disposed movably in the outer barrel, a decorative unit coupled to the rotary component, and a limiting unit. The limiting unit includes a press ring that is movably retained in the decorative ring, and that abuts against one end of the object lens unit, and a biasing member disposed in the outer barrel and abutting against the other end of the object lens unit, thereby securing the object lens unit between the biasing member and the press ring.
