The present specification relates to a contact lens having an integrated light source for electroretinography and a method for preparing same, the contact lens, having an integrated light source for electroretinography, comprising: a light source; a scattering material for scattering light from the light source; and an electrode for measuring changes in the electroretinogram due to the stimulation from the light source.

The present invention relates to a system for corneal crosslinking of injured corneas, treating keratoconus, or correcting vision, the system comprising: a hyaluronic acid-dye conjugate; and a contact lens including an LED light source.

In the present invention, a dye is activated by receiving light irradiated from the LED light source of the contact lens so as to generate radicals, thereby generating a covalent bond between amino acid radicals of corneal collagen, and strengthening a collagen layer. In the present invention, the hyaluronic acid-dye conjugate, in which hyaluronic acid is bound to the dye, is used to improve penetration of the dye in the cornea, and the contact lens is used together with the hyaluronic acid-dye conjugate to further improve the penetration of the dye. In addition, the structure of the lens which presses the center of the cornea deforms the shape of the cornea, thereby having a vision correction effect.

An electronic case for electronic spectacles may include a base comprising a cavity formed therein. A first spectacle retention device may be located within the cavity. The first spectacle retention device may be configured to retain spectacles. An electrical control system may be included. An electrical connector may be configured to couple the electrical control system in electronic communication with the spectacles.

In certain embodiments, an ophthalmic procedure contact lens for ophthalmic treatment of an eye with a laser beam includes a frame, an objective lens, and an illumination ring. The frame has an eye end, an operator end, and a flange-like shape with an interior region. The eye end is configured to be disposed outwardly from the eye. The objective lens is disposed within the interior region of the frame. The objective lens transmits the laser beam through the eye end to treat the eye. The illumination ring is coupled to the frame and provides annular illumination through the eye end to illuminate the eye. The illumination ring includes a ring substrate and light emitters coupled to the ring substrate. The light emitters emit light.

A contact lens configured to decrease dark adaptation comprises one or more LEDs and directs light from the LED away from the fovea and toward the parafovea or perifoveal regions of the retain. In some embodiments, soft contact lens embedded with one or more arrays of microLEDs and electronics operating the LEDs is configured to be worn at night in order to inhibit dark adaptation and reduce oxygen consumption by the rods. The contact lens may be made of a single layer of a contact lens material or multiple layers sandwiching a flexible transparent plastic layer comprising the electronics and the LED arrays. The contact lens may be made of a hydrophilic hydrogel material that is biocompatible to the human cornea, or a silicone hydrogel material. The contact lens may be spherical and may provide refractive correction to the eye of the wearer.
