Ed is suffering from macular degeneration. He's color blind and using a computer is getting harder. Leo says making the characters bigger and bigger on the resolution settings. But Ed says he also has Retinitus Pigmentosa, which is like looking through a milky glass, so making the characters larger doesn't help much. At some point, screen readers like JAWS can help. But they're very costly. Ed should check with the Foundation for the Blind and Lighthouse for the Blind for assistance. There's a Chrome plugin called Deluminate, which inverts the luminance of a website. There's also open source screen readers like NVDA.
