Bipolar progressive power ophthalmic lenses are described, the constant power distance portion and reading portion regions of the progressive power surface being reduced to mathematical points and the surface astigmatism aberration is spread over a maximally large area of the lens. The points are the ...

The first thing an MTF chart displays is the distance from the center to the corner of a “full-frame” image. All MTF charts for Canon EF, TS-E and MP-E lenses assume a full-frame image at 36x24mm in size (the same size as a traditional 35mm film negative or...
A technological visionary in the field of optics, Clarium Lens has made it to the front page for its announcement of introducing an advanced broad range of Clarium Lux lens products which would help the company to build a competitive portfolio. As per credible sources, the newly included range...

NaviLens is a high-density artificial markers system for long distance reading. The tags generated by this system are designed in order to be read from a long distance, without the need of focussing and even in motion. This makes them useful for blind and low vision people. All you need ...
This creates problems: Using Gaze to target UI components that are on distant objects can be difficult, and icons can be difficult to discern from far away. The ConstantViewSize Solver addresses this by scaling the UI component up or down based on the user’s distance. For this sample app...
For example, I can simulate very shallow depth of field with this lens, even though it's a 24mm. That lets you get really creative and make some truly amazing images.THINGS THIS LENS IS GOOD AT:- Tilt shift photographs.- Macro, due to the super low minimum focus distance.- Very low ...

Furthermore, measurements were taken at a curvature of 15 mm, which represents the extreme risk of the cornea for developing glaucoma [2]. The distance between the two rings was measured by using the microscope’s built-in software (Zen Software: Saint-Louis, MO, USA). Figure 2. ...
