An eye-mounted device includes a contact lens and an embedded imaging system. The front aperture of the imaging system faces away from the user's eye so that the image sensor in the imaging system detects imagery of a user's external environment. The optics for the imaging system has a folded optical path, which is advantageous for fitting the imaging system into the limited space within the contact lens. In one design, the optics for the imaging system is based on a two mirror design, with a concave mirror followed by a convex mirror.

A variety of femtoprojector optical systems are described. Each of them can be made small enough to fit in a contact lens using plastic injection molding, diamond turning, photolithography and etching, or other techniques. Most, but not all, of the systems include a solid cylindrical transparent substrate with a curved primary mirror formed on one end and a secondary mirror formed on the other end. Any of the designs may use light blocking, light-redirecting, absorbing coatings or other types of baffle structures as needed to reduce stray light.

A device includes the elements of full eye coverage goggles and magnifying binocular loupes. So wearers have eye protection against small particles, such as virus when doing delicate procedures requiring magnification to fine details. The device could work with other personal protective equipment to reach higher level protection.

In various examples, a dental and medical loupe system for lighting control, streaming, and augmented reality (AR) assisted procedures is provided. Facial recognition algorithms and/or inertial measurement unit (IMU) sensors may be used to determine when a light disposed on eye-glasses of a wearer should be activated. As a result, instead of requiring a medical practitioner to manually turn on and off the light source, facial recognition may be used to determine when the dentist is looking toward a face of a patient, and to turn on the light when a face is present and off when a face is not present. In addition, some examples leverage augmented reality (AR) functionality to overlay patient and procedure information on one or more lenses of eye-glasses worn by a practitioner to allow for an un-occluded view of the actual location where the procedure is being performed.

A method of obtaining ophthalmic measurements. An individual wears frames. Control simulations are performed to determine an average far gaze view line, average intermediate gaze view line, and average near gaze view line. The average far gaze view line intersects the lens plane at a second intersection point. The average intermediate gaze view line intersects the lens plane at a third intersection point. The average near gaze view line intersects the lens plane at a fourth intersection point. The far region extends from a first position above the first intersection point to a second position below the second intersection point. The intermediate region extends from the second position to a third position below the third intersection point. The near region extends from the third position to a fourth position below the fourth intersection point. The control simulation takes into account the height and stature to fit the natural viewing dynamic.

A method for determining filtering capabilities of a magnification device suitable for providing protection from light when viewed through the magnification device is disclosed. The filtering capability of the magnification device is determined based at least one of an input power of the inputted light signal, a magnification level of the magnification device and an orientation of the filtering within the magnification device. Further disclosed is an lighting system that generates a light, which when reflected into the magnification device is prevent from causing damage to a user's eyes based on the selection of the filtering system disclosed herein.

A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

A protective loupes eyewear assembly having an eyewear frame with magnifying loupes. The eyewear frame has notches in the top of the frame and a bottom shelf structure on the inside of the frame. An insert assembly with a pair of outwardly extending tabs and a mating configuration is constructed to slip into the notches at the top of the eyewear frame and into a bottom shelf structure behind the eyewear frame to provide laser protection for use in the dental, surgical and other arts.

The present invention is attachable lenses to provide ability to increase capacity to read or focus on otherwise unseen details of objects, the attachable lenses provide magnification and the ability to have reading glasses on otherwise non magnified lenses as in safety glasses or sunglasses. The attachable lenses of the present invention provide a dual-use eyeglasses, a pair of glasses made for far sight and the attachable lenses applied to said glasses for close reading. The attachable lenses disclosed in the invention are capable of being manufactured in glass or hard plastic lenses of varying magnification strength which are attached to the non-magnified lenses of various types of glasses or spectacles by means of adhesion, either liquid adhesion or attached adhesive tape, both the liquid adhesive or adhesive tape being optically transparent to allow amplified vision.

In an embodiment, a modular augmented reality display is provided that incorporates prescription eyewear that can be used separately by the wearer. In an embodiment, an image is generated from a removable display attached to the eyewear and directed into the edge of a prescription lens, which acts as a waveguide. The image is internally reflected within the prescription lens, and is directed to the wearer by an image combiner embedded within the prescription lens. In an embodiment, the augmented reality display includes a wearable belt pouch that includes a battery and support electronics connected to the eyewear so that the weight on the eyewear is reduced.
