Abstract: A method for modifying focal length of lenses of a HMD in accordance with a user's eyeglass prescription data and without the user having access to the eyeglass prescription data is disclosed. The method includes receiving an identifier that uniquely represents the user viewing content on the HMD. The method also includes obtaining eyeglass prescription data corresponding to the unique identifier that includes data for correcting eye defects of the user. The data is then applied by modifying optical properties such as focal length of the lenses to provide corrected vision to the user while the user views content on the HMD without the user having to wear prescription eyeglasses or contact lenses.

Abstract: Embodiments of the invention generally provide electrochromic devices and materials and processes for forming such electrochromic devices and materials. In one embodiment, an electrochromic device contains a lower transparent conductor layer disposed on a substrate, wherein an upper surface of the lower transparent conductor layer has a surface roughness of greater than 50 nm and a primary electrochromic layer having planarizing properties is disposed on the lower transparent conductor layer. The upper surface of the primary electrochromic layer has a surface roughness less than the surface roughness of upper surface of the lower transparent conductor layer, such as about 50 nm or less.

Abstract: A fisheye lens filter for a fisheye lens includes an optically clean dome sized to fit over the fisheye lens. The dome includes in some embodiments a coating layer(s) to filter out light as desired for use in recording an image. The fisheye lens filter provides an unobstructed field of view in front of fisheye lenses preventing optical aberrations such as vignetting while providing filtering effects.
Abstract: A projection lens includes: first to fifth lenses; a light shielding ring; an aperture stop; and a lens barrel. The light shielding ring is rotated in a circumferential direction of the lens barrel by a rotation mechanism. In a case where an image forming panel is shifted with respect to an optical axis of the projection lens, a part, through which the light passes, is biased in the projection lens, whereby temperature distribution occurs in the lens barrel in the direction perpendicular to the optical axis. The thermal deformation of the high temperature side of the lens barrel due to the temperature distribution is greater than that on the low temperature side. The respective lenses may be tilted due to thermal deformation. By rotating the light shielding ring through the rotation mechanism, the temperature increases uniformly in the circumferential direction of the light shielding ring.
Abstract: An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. At least one lens among the first to the sixth lenses has positive refractive power. The seventh lens can have negative refractive power, wherein both surfaces thereof are aspheric, and at least one surface thereof has an inflection point. The lenses in the optical image capturing system which have refractive power include the first to the seventh lenses. The optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.
