A method for projecting a light beam on a retina of a user via eyewear worn by the user, the method comprising: receiving, via a network overlay of the eyewear, image data and/or video data from a remote device; converting, via a source of the eyewear, the image data and/or video data into a light beam; coupling, into a beam steering device (300, 400, 500) of the eyewear, the light beam as an incident light beam orthogonal to a first plane of a first overlay (340, 440, 540) of the beam steering device (300, 400, 500), the first overlay (340, 440, 540) being coupled to a substrate of the beam steering device (300, 400, 500), the substrate having a first refractive index, the substrate defining a cavity (370, 570) having an electroactive material disposed therein, the electroactive material exhibiting a variable refractive index; receiving, at a second overlay (345, 445, 545) of the beam steering device (300, 400, 500), the incident light beam from the electroactive material, the second overlay (345, 445, 545) defining a second plane tilted with respect to the first plane to define a tilt angle; steering the incident light beam by simultaneously applying a first electric field to the electroactive material between the first overlay (340, 440, 540) and the second overlay (345, 445, 545), and a second electric field to the electroactive material between a third overlay (330, 430, 530) and a fourth overlay (335, 435, 535) of the beam steering device (300, 400, 500), the third overlay (330, 430, 530) and the fourth overlay (335, 435, 535) each defining a plane (P1, P2) orthogonal with respect to the first plane, such that the electroactive material attains a second refractive index based on a strength of the first electric field and the second electric field; and outputting, after refraction by the second overlay (345, 445, 545), the incident light beam as an output light beam onto the retina of the user, wherein the applying the first electric field includes applying a first electrical signal to an electrode layer of the first overlay (340, 440, 540) and to an electrode layer of the second overlay (345, 445, 545), and wherein the applying the second electric field includes applying a second electrical signal to an electrode layer of the third overlay (330, 430, 530) and to an electrode layer of the fourth overlay (335, 435, 535), wherein the electroactive material comprises a liquid crystal material, and wherein one or more of the first overlay, the second overlay, the third overlay and the fourth overlay (340, 440, 540;
