Abstract
A lens assembly can be removably attached to an eye cone of a HMD. The eye cone displays images to an eye of a user of the HMD. The eye cone includes a peripheral wall that extends towards rear of the HMD. The lens assembly includes a corrective lens and a frame. The corrective lens corrects a vision error of the eye of the user. The frame includes an inner surface onto which the corrective lens is attached. The frame also includes a wall that receives a peripheral wall of the eye cone for removably securing the lens assembly to the HMD. The HMD can include another eye cone that displays images to the other eye of the user. Another lens assembly can be removably attached to the other eye cone.
