Presentation professor Andrew Abela suggests when you design a page in your presentation, you use the squint test to tell if the page's purpose if obvious enough to your audience. Squint your eyes at the page and try to guess what the page is about, using only the blurry information you can see. If you can successfully guess the purpose of the page while squinting, your page is obvious enough For example, if you squint at the page and you clearly see that the items on your page are converging together and your presentation is about items converging, your page is obvious enough for your audience.
Obviously,
