Scotopic Tester and Filter Printer APK

In this release the filters are closer to the filters developed by Arnold Wilkins. I would like to thank Professor Wilkins for his work on this subject.

Scotopic Sensitivity Syndrome (also known as Irlen Syndrome) is a syndrome where people perceive printed matter more clearly using a colored transparency. Some signs of Scotopic Sensitivity Syndrome include letters that appear to vibrate, headaches while reading, halos around words when reading and skipping lines while reading. Using an overlay of the right color helps perception and thereby indirectly contributing to one's ability to read.
Many teachers have reported improved success when teaching reading with this technique as an adjunct.
This program goes through the color spectrum and allows one to compare two different colors on the screen to see which one is most helpful for perception. According to researchers, the overlay on the page doesn't need to be very specific to be of help.

If one were to place a lens over the eye then the precision needs to be much greater.
If you would like glasses with tinted lenses to help with perceptual problems due to Scotopic Sensitivity Syndrome then go to an Irlen Center. There is one in Long Beach, CA.

To use this app you must have a printer that will print overhead transparencies. You will also need to buy your own overhead transparencies that work with your printer. After selecting the color filter that is most appropriate, you may e-mail the filter to yourself for printing or some printers have phone software that will allow you to send the filter directly to the printer.

When you print the software make sure the page set up is set to print the whole page.
