摘要： Astigmatism is an optical aberration that displaces the eye's vertical focal plane with respect to its horizontal focal plane. This displacement in focal planes, which may be caused by an irregularly shaped cornea and/or crystalline lens, causes images to appear blurry. Astigmatism can be corrected by implanting an optic, such as section of a spherical lens, whose projection onto a plane perpendicular to the optical axis is noncircular (e.g., rectangular or elliptical). Because the optic is noncircular, it provides more optical power along one axis than along another axis. As a result, it introduces an astigmatism that can be used to offset or compensate the eye's corneal and/or lenticular astigmatism when aligned properly with respect to the principal meridians of the cornea and/or crystalline lens.

摘要： An optical and mechanical design of a sealed, non-round fluid-filled lens capable of providing variation of optical power. The fluid lens includes at least three optical components: at least one mostly rigid optical disc, at least one mostly flexible optical membrane and a layer of a transparent fluid that is in communication via a fluid channel with a reservoir of excess fluid contained in a reservoir that can be accessed to augment the fluid volume inside the fluid lens to change the power of the fluid lens. The fluid lens is capable of providing correction of spherical and astigmatic errors, and utilizes contoured membranes to provide for a substantially constant desired spherical power over a substantially full field of view of a user.

摘要： Aspects of the present invention provide an ophthalmic lens comprising at least one regressive and at least one non-regressive rotationally symmetric optical design element. The regressive and non-regressive optical design elements can be combined so as to form a desired optical power profile for the lens while simultaneously exploiting the different relative orientation of the astigmatic vectors of the constituent regressive and non-regressive design elements, thereby resulting in reduced unwanted astigmatism. The regressive and non-regressive rotationally symmetric optical design elements can be positioned on different lens surfaces and in optical communication or can be collapsed onto the same lens surface. The regressive and non-regressive rotationally symmetric optical design elements can each contribute to the total add power of an ophthalmic lens. The regressive and non-regressive rotationally symmetric optical design elements can be combined with any other optical design feature positioned on the same or a different surface of the lens.

摘要： An endoscope realized as either a borescope or a fiberscope including one or more fluid filled lenses is described. In an embodiment, the optical power of the fluid filled lenses may be adjusted to adjust the focal length associated with the endoscope. Thus, variable working distances are allowable while maintaining focus on an object in front of the endoscope. The endoscope may include a distance sensor, which is used to determine a distance between the endoscope and a sample. A processor may compare the measured distance to the current optical power of the one or more sealed fluid filled lenses. The processor may transmit signals to one or more actuators coupled to one or more sealed fluid filed lenses to change the optical power of the one or more sealed fluid filled lenses based on the comparison.

摘要： A binocular loupe containing one or more sealed fluid filled lenses is described. The binocular loupe includes one or more eyepieces, a distance sensor, and control electronics. In an embodiment, the optical power of the fluid filled lenses may be adjusted to adjust the focal length associated with the binocular loupe. The distance sensor may be used to determine a distance between the binocular loupe and a sample while a controller compares the measured distance to the current optical power of the one or more sealed fluid filled lenses. The controller may transmit signals to one or more actuators coupled to one or more sealed fluid filled lenses to change the optical power of the one or more sealed fluid filled lenses based on the comparison.
