Publication number: 20190353930Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include an inner optic portion having a scaffold between an anterior portion and a posterior portion. The scaffold is characterized by a substantially uniform thickness formed from a material characterized by a modulus that his higher than the modulus of the peripheral portion. Openings within the scaffold are filled with a low modulus material. When applied to an eye, the lenses are configured to provide one or more lenticular volumes between the posterior surface of the lens and the cornea. The disclosure further relates to methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses.Type: ApplicationFiled: August 5, 2019Publication date: November 21, 2019Inventors: Eugene de Juan, JR., Cary J.

Patent number: 10459255Abstract: An eye-mounted display is used to enhance vision of a user with visual impairment. Images of a user's unimpaired view of a surrounding environment are captured. These image are modified to compensate for the user's visual impairment. For example, the captured images can be magnified, an angular extent of the captured images can be compressed, or a contrast of the captured images can be enhanced. Also, the captured images can be modified by including identification of an object, a face, or an emotion. For a captured image including text, the text in the captured images can be modified. The eye-mounted display projects the compensated images onto the user's retina. When the user's retina has a damaged section, the eye-mounted display projects the compensated images away from the damaged section.Type: GrantFiled: February 1, 2018Date of Patent: October 29, 2019Assignee: Tectus CorporationInventors: Kuang-mon Ashley Tuan, Michael West Wiemer

Publication number: 20190324292Abstract: An eye-mounted display includes a scleral contact lens with one or more femtoprojectors that project images onto the user's retina. The scleral contact lens has a non-circular perimeter, for example elongated along the direction of the eye opening. The non-circular shape can result in less slippage and/or rotation of the contact lens relative to the eye. If the contact lens is elongated (compared to traditional circular lenses), then it can contain conductive coils that enclose a larger area. Thus, the lens increases coupling efficiency for power or data transfer. There can also be more space within the contact lens for payloads.Type: ApplicationFiled: April 18, 2018Publication date: October 24, 2019Inventor: Kuang-mon Ashley Tuan

Publication number: 20190235276Abstract: An eye-mounted device includes a contact lens, a femtocamera, and a femtoprojector. The femtocamera and femtoprojector are both contained in the contact lens. The femtocamera detects imagery of a user's surrounding environment, and the femtoprojector projects corresponding imagery to the user's retina. A line of sight of the femtocamera and a line of projection of the femtoprojector can be parallel to, or even collinear with, each other. Imagery signal paths from the femtocamera to the femtoprojector are also contained in the contact lens. In some embodiments, the imagery signal paths are register-less and asynchronous. The eye-mounted device can include other components, such as image processing circuitry. Also, the eye-mounted device can communicate with another device worn by the user, e.g., in a necklace or a headpiece.Type: ApplicationFiled: February 1, 2018Publication date: August 1, 2019Inventors: Michael West Wiemer, Kuang-mon Ashley Tuan

Publication number: 20180149884Abstract: An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.Type: ApplicationFiled: November 27, 2017Publication date: May 31, 2018Inventors: Gregory David Miller, Brian Elliot Lemoff, Kuang-mon Ashley Tuan, Herbert John Kniess, Ion Opris, Michael West Wiemer, Drew Daniel Perkins

Publication number: 20170131566Abstract: Methods and apparatus can fit coverings to treat eyes. The treated eye may comprise a natural eye, for example an eye treated for refractive error with a contact lens, or an eye having an epithelial defect of the eye, such as an eye ablated with PRK refractive surgery. In many embodiments, the covering can be identified so as to provide improved flow of tear liquid under the covering. The covering can be identified based on an inner corneal curvature and an outer corneal curvature and one or more of a limbus sag height or a conjunctival sag height. The covering may form a chamber when placed on the eye to pump tear liquid under at least a portion of the covering. The covering may comprise an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration.Type: ApplicationFiled: June 16, 2016Publication date: May 11, 2017Inventors: Eugene de Juan, JR., Yair Alster, Cary J.
