Apple patents headsets with swappable lenses for better vision
Apple describes a head-mounted display system that uses a fixed lens to adjust the basic focus of the image for different users. It adds a separate, removable prescription lens to correct specific eye issues like astigmatism, reducing the need for many custom parts.
In the filing’s own words
A head-mounted device may include a support structure that supports a display and a fixed lens. Vision correction lenses may be removably coupled to the fixed lenses to help customize the head-mounted device to the vision of a particular user. To reduce the number of prescription lenses needed on hand at a demonstration site, the demonstration site may include multiple head-mounted display units with different virtual image distances for providing different amounts of spherical correction to the displayed image. For example, a baseline unit may accommodate users that do not require a prescription, a myopic unit may accommodate nearsighted users, and a hyperopic unit may accommodate farsighted users. These different head-mounted display units, when combined with the cylindrical correction of a supplemental prescription lens, may be configured to accommodate a greater number of prescriptions with a fewer number of supplemental prescription lenses on hand.
What exactly they claim (claim 1)
1. A head-mounted device, comprising: a support structure; a display coupled to the support structure and configured to display an image; a lens through which the display is visible from an eye box, wherein the display and the lens are separated by a distance that imparts a spherical correction to the image; and a supplemental prescription lens that imparts a cylindrical correction to the image.
