Color Overlays Views
You can use two types of overlays: a simple one that uses a single overlay color and an advanced one that uses up to four overlay colors. For many menus, a simple overlay will provide what you need with minimal complexity. You may find, however, that an advanced overlay provides greater flexibility when you are creating complicated menus.
As a consequence of hardware overlay use, a screenshot program (for example, the one automatically built into Windows that activates when a user presses the PrtSc key) often does not capture the content appearing in the hardware overlay window. Rather, a blank region containing only the special mask color is captured. This is because the screen capture routine doesn't consider the special video memory regions dedicated to overlays - it simply captures the shared main screen as rendered by the software's graphical subsystem. Some Digital Rights Management schemes use hardware overlay to display protected content on the screen, taking advantage of this quirk to prevent the copying of protected documents by way of screen capture[citation needed]. Disabling the support for overlays causes the normal overlay-using software to fallback to the shared memory, thus enabling screenshot capture.
Irlen Overlays are the original colored overlay technology. They are used by hundreds of thousands of students and over one-million people worldwide. Irlen Overlays are the only colored overlays available backed by more than a decade of scientific research and used by more than 4,000 school districts worldwide.
Colored overlays are most effective for individuals whose difficulties are isolated to reading. If you experience challenges with writing, math, depth perception, night driving, or the environment, colored filters (worn as glasses) will be your best treatment option. However, colored overlays are an important first step in determining whether the Irlen Method can work for you and provide your first experience with relief.
