An optical system includes, from an image side to an object side, a first lens having a positive refractive power, a second lens having a positive refractive power, and a third lens having a negative refractive power. The first lens, the second lens, and the third lens form an optical path with the object side facing a screen and the image side adapted to provide an image from the screen to a user. In one aspect, the optical system is adapted to correct at least one of a group of aberrations including astigmatism and field curvature; or, lateral color.

An embedded reflective eyepiece includes an optical lens, a beam splitter and reflective coating at a convex surface of the optical lens and a circular polarizing reflector surface having a concave surface of the optical lens. A method for forming a magnified image includes emitting circularly polarized light from a display source, at least partially refracting the circularly polarized light across a convex surface of a beam splitter reflective coating across a lens, at least partially reflecting refracted circularly polarized light internally off a concave circularly polarized reflector surface of the lens, and at least partially reflecting a reflected circularly polarized light internally off of the beam splitter reflective coating at the convex surface.

A lens assembly includes at least three lens elements. One lens element closest to an imaged object of the lens elements is a first lens element, which is made of an electromagnetic radiation absorbing material.

Provided herein are disclosures relating to systems and methods of detangling jewelry. The jewelry detangling system may include a body, the body further including a cavity and a plurality of arms located in a cavity of the body and operably coupled therein. The plurality of arms further include corresponding beds dimensioned to receive jewelry pieces thereon during the detangling process. A magnifier including a frame and a lens may be coupled to the body of the jewelry detangler and rotatable about a hinge thereon about a plurality of positions.

The present invention is a magnified screen cover and protector for electronic devices. The invention comprises a magnified surface layer with a top protective layer and a bottom adhesive layer. The invention magnifies the screen of an electronic device with diopter and/or magnification power ranges so that the user may comfortably use the electronic device without the aid of wearing prescription eyewear, contact lenses, reading glasses or other visual aids. The touch screen sensitivity and functionality of the electronic device is unaffected by the magnified screen cover protector, so usability of the electronic devices touch and sensitivity functions are not compromised. The present inventions additional benefit is protecting the glass and/or plastic surface of an electronic devices main viewing screen from scarring, shattering, debris and breakage. Other embodiments of the magnified screen cover protector would include a three dimensional (3D) magnification layer for viewing text images, and video in a three dimensional (3D) visual simulation on an electronic devices screen.

A See-Through Display System with the ability to correct visual deficits such as presbyopia, color blindness and poor night vision is disclosed. This invention enables the correction of visual deficits using camera(s), microdisplay (s), controlling circuit(s) with digital grayscale control and see through optics such as free form lens/mirror, half-mirror, diffractive and/or holographic optical element(s).

A method and a mirror selectively magnify an image reflected by a discrete portion of a reflective area of the mirror while an image reflected by the remainder of the reflective area outside the discrete portion remains unchanged. A light-transmitting area is placed within the reflective area, outside of and adjacent to the discrete portion, and a light source is located for directing light through the light-transmitting area to illuminate a space adjacent to and confronting at least the discrete portion of the reflective area.

Optical systems for displaying an image are described. The optical systems include a first and second optical lenses separated by air. A partial reflector is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature in a range from 20 mm to 200 mm. A reflective polarizer is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature greater than about 500 mm. A retarder layer is disposed between the reflective polarizer and the partial reflector. The first optical lens can have an optical birefringence of less than 15 nm/cm and the second optical lens can have an optical birefringence of greater than 15 nm/cm. A method of fabricating an optical assembly is described.

An ocular optical system for imaging of imaging rays entering an eye of an observer via the ocular optical system from a display screen is provided. A side facing towards the eye is an eye-side, and a side facing towards the display screen is a display-side. The ocular optical system includes a first lens element, a second lens element, and a third lens element from the eye-side to the display-side in order along an optical axis. The first lens element, the second lens element, and the third lens element each include an eye-side surface and a display-side surface. Lens elements having refracting power of the ocular optical system are only the first lens element, the second lens element, and the third lens element.

An optical system for a virtual image display device includes a light guide, a reflector, and an intermediate image forming portion. The light guide is configured to guide image light emitted from an image display element that displays an image, to proceed in the light guide. The light guide includes a partial reflector, a first portion on one side of the partial reflector, and a second portion on another side of the partial reflector. The partial reflector transmits the image light incident from the first portion and reflects the image light incident from the second portion to guide the image light to exit the light guide. The reflector reflects the image light transmitted through the partial reflector and the second portion back to the partial reflector. The intermediate image forming portion forms an intermediate image with the image light in the light guide.
