Tunable non-round fluidic lens with immersed lens shaper

The optical device according to one of the preceding claims, characterized in that the container (2) forms a semi-finished lens-blank having a circumferential boundary region (2a) that is configured to be at least one of:

• formed, shaped, machined, cut, sanded, milled, in order to form an outer contour (10a) of the container (2) that fits a desired frame (10), particularly a spectacle frame (10), for holding the container (2).

The optical device according to one of the preceding claims, characterized in that the optical device (1) comprises a front lens (40) arranged in front of the membrane (21) of the front wall (20) for protecting the membrane (21) and for providing a base refractive power.

The optical device according to one of the preceding claims, characterized in that the container (2) comprises a spacer ring (50) arranged between the lens shaper (22) and the back wall (30).

The optical device according to one of the preceding claims, characterized in that the spacer ring (50) forms a sealing ring for the container (2).

The optical device according to one of the preceding claims, characterized in that the optical device (1) comprises an actuator means (60) which is configured to adjust said volume (V) of the first lens (100) in order to adjust the curvature of said curvature-adjustable area (23).

The optical device according to one of the preceding claims, characterized in that adjusting said volume (V) comprises compressing a portion of the volume (V) so that the liquid contained in the volume (V) presses against the membrane (21) and thereby adjusts the curvature of said curvature-adjustable area (23), and/or wherein adjusting said volume (V) comprises expanding a portion of the volume (V) so that the fluid (F) presses less against the curvature-adjustable area (23) of the membrane (21) and thereby adjusts the curvature of said curvature-adjustable area (23).

The optical device according to one of the preceding claims, characterized in that the optical device (1) comprises an actuator means (60) which is configured to pump fluid (F) into and/or out of the volume (V) to adjust said volume (V) of the first lens (100).

The optical device according to one of the preceding claims, characterized in that the container (2) comprises a pierceable seal (27).

The optical device according to one of the preceding claims, characterized in that the lens shaper (22) is connected to the back wall (30) via a hinge (53) so that the lens shaper (22) can be pivoted with respect to the back wall (30).

The optical device according to one of the preceding claims, characterized in that the lens shaper (22) is connected to the back wall (30) via a circumferential flexible seal member (28).

The optical device according to one of the preceding claims, characterized in that the optical device (1) comprises a second lens (200) having an adjustable focal length.

The optical device according to one of the preceding claims, characterized in that the optical device (1) is formed as a pair of spectacles, particularly for virtual reality or augmented reality, or a headset (1), particularly for virtual reality or augmented reality, wherein the first and/or the second lens (100, 200) are held by a frame (10) that can be worn by a user such that the respective lens (100, 200) is arranged in front of an associated eye of the user.

The optical device according to one of the preceding claims, characterized in that the optical device (1) is configured to adjust a focal length of the first lens (100) and a focal length of the second lens (200) simultaneously, particularly once a base correction has been set for each lens (100, 200).
