Abstract: The present invention is directed to a method and means for enabling contact lens wearers to photograph their own eyes using an electronic device with a camera such as an iPhone with a macro lens, for example, Olloclip® Macro Pro Lens Set 7× lens, and a custom three-dimensional printed eyecup attachment. The eyecup attachment is designed to position the camera at a suitable and reproducible distance from the eye to ensure that the system can focus appropriately on the lens details. The eyecup attachment also serves to block stray light and diffuse the ambient lighting. In addition, the eyecup attachment ensures that the camera is held in the correct orientation while photos are being captured. The capture images are analyzed using image processing software to determine the angel of rotation of the contact lens.

Abstract: Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface and defining a volume of lens material therebetween. The ophthalmic lens may exhibit a first cylinder power. A difference of the volume of lens material of the ophthalmic lens and a volume of lens material of a comparative lens may be minimized. The comparative lens may consist essentially of the same lens material as the ophthalmic lens and exhibit a second cylinder power different from the first cylinder power.

Abstract: A method of measuring the thickness of an ophthalmic lens includes forming an ophthalmic lens over a convexly curved surface of a forming optic, the ophthalmic lens including a light absorptive component, and with the ophthalmic lens remaining over the convexly curved surface of the forming optic, measuring the thickness of the ophthalmic lens using information about the light absorptive component of the ophthalmic lens and an intensity reference value associated with the forming optic. The method includes passing light having a wavelength through the ophthalmic lens and the forming optic, whereupon the light absorptive component of the ophthalmic lens absorbs some of the light passing through the ophthalmic lens. The light passing through the ophthalmic lens and the forming optic, which is not absorbed by the light absorptive component of the ophthalmic lens, is used to generate an image having pixel intensity data.

Abstract: The present invention is directed to a system that may be incorporated into currently available electronic devices such as laptops, cell-phones and tablets, that help the user to maintain a viewing distance that is safe for the eyes. In order to avoid near-point stress on the eyes which may lead to the onset of myopia and/or accelerate the progression of myopia, especially in children or young adults, the system of the present invention monitors viewing distance and automatically distorts the image and/or text display into a format that is unreadable, for example, through blurring or pixilation, when the device is too close to the viewer. Alternatively, the system may automatically turn off the display when the device is too close and turn the display on when the device is at the proper viewing distance.

In particular, the present invention relates to a composition comprising an esterified anti-inflammatory lipid mediator, which is an ester of an anti-inflammatory lipid mediator that is a reaction product of the anti-inflammatory lipid mediator and a polyol wherein the majority of the anti-inflammatory lipid mediator is present in an ester form.
