    An optical design for an immersive head-mounted display (HMD) with a liquid lens is described. This design combines the liquid lens with an immersive HMD system to improve the image quality for myopic and hyperopic users. A penta-prism is also incorporated and used to change the direction of the optical path to improve any optical aberration caused by the gravity effect. This immersive head-mounted display has a field of view of 14.9 degrees, focal length of 47.78 mm, and f-number of 5.97 with an exit pupil diameter of 8 mm, eye relief of 15 mm. The value of the MTF is above 0.9 at 3.3 lp/mm.
