Vision correction for near eye display

An optical system, comprising:

• a first lens that is flexible, and
• a vision correction adapter, wherein
• a shape of the vision correction adapter is based on a degree of astigmatism and an orientation of the astigmatism, and
• the vision correction adapter is configured to alter a shape of the first lens to conform to the shape of the vision correction adapter to correct for the astigmatism.

An optical system, comprising:

• a first lens that is flexible and includes a first optically transparent member having a first surface and a second surface, and
• a vision correction adapter, wherein
• a center region of the vision correction adapter includes an opening,
• a tilted surface of the vision correction adapter is tilted with respect to an optical axis of the optical system,
• a tilt angle and an orientation of the tilted surface of the vision correction adapter are based on double vision, and
• the vision correction adapter is configured to tilt the first lens according to the tilt angle and the orientation of the tilted surface of the vision correction adapter to correct for the double vision.

An optical system, comprising:

• a first lens including a first optically transparent member having a first surface and a second surface,
• a second lens including a second optically transparent member having a third surface and a fourth surface, and
• a vision correction adapter, wherein
• at least one of the first lens or the second lens is flexible,
• a center region of the vision correction adapter includes an opening, and
• the vision correction adapter is configured to perform a plurality of (i) altering a distance between the first lens and the second lens to correct for one of nearsightedness and farsightedness (ii) altering at least one of a shape of the first lens or a shape of the second lens to conform to a shape of the vision correction adapter to correct for astigmatism and (iii) tilting at least one of the first lens or the second lens according to the shape of the vision correction adapter to correct for double vision.

A method of fabricating a vision correction adapter for an optical system, the method comprising:

• obtaining vision correction information for at least one of nearsightedness, farsightedness, astigmatism, or double vision;
• determining one or more of (i) a thickness of the vision correction adapter or (ii) a shape of the vision correction adapter based on the vision correction information;
• and
• fabricating the vision correction adapter based on the determined one or more of the thickness of the vision correction adapter or the shape of the vision correction adapter, a center region of the vision correction adapter being hollow.
