Lens is a skinnable graphic tool for viewing the screen area in different zooms (magnify from 1x to 64x). This program was designed as a demo of the krpRegions library (the library for creating cool looking user interfaces), however, many people with poor eyesight have found a freeware version of this program very helpful. Lens has a skinnable interface (Figure 11), so you can modify the program's appearance for your convenience. You can also easily create your own "skins" for this program, using any graphic editor. Here are some examples of the skins:

You can specify zoom, refresh rate, and the name of skin file. For Win2k and higher there are some working modes, you can choose a preferred one. Also you can use a popup menu (Figure 13) to mange the program.
